ID'ing L50 and L52 transmissions

L45 4-speed (what you have) and a L50 5-speed both use either a 63/32N input bearing or a 032-2.

The L52 5-speed, which was only available in 1983, has a slightly stronger input bearing with either B32-14UR or 32BC08S1N part number written on the bearing race.

You will need to remove the nose cone from the transmission to expose and read the numbers from the input bearing race.

Really pulling the front nose cone is going to be the best way to ID the transmission.

There actually is a way to know if the transmission is from an 83 simply by reading the serial number stamped into the bottom of the cast iron housing. If the first and second digits are 211 or 212, or if the first number is a 3, then 100% no questions asked it is a L52.

Identification:
G52/54 84-88' are twin stick, use a 8 bolt center section, 6 bolt gear t/case pattern, 21 spline output.
G58 89-95' twin stick, 8 bolt center, 9 bolt chain t/case, 26 spline
W56 85-88' (single stick), 89-95' (twin stick), 10 bolt center, 6 bolt t/case, 21 spline
R151F 86 - 87 (turbo only) will have two housings of four bolts each just like a G52, the difference would be the large rubber plug on the bottom of the bellhousing.

Info provided by Marlin Crawler
All 84 to 95 22R trans are 25.5" long including the bellhousing. The only shorter trans is the 79-83 year trans which are 20.75" long with bellhousing. These early short trans have had a poor service record due in part to their small bearings and lighter gears. The 82-83 L52 5 speed which had a 80 x 20 mm front input bearing has had the best service record. A number of years ago, I invented a way to install a oversize 80 x 23 mm input bearing with an inproved gear set which features a greater helix angle for added strenght. I call it my L52HD and is the strongest 20.75" long trans.

whoa thanks 4crawler, been looking for this for a while now. Don't like the 3-4 shift in my g54???? Not that there is anything wrong with the trans just seem to me like too big of a jump.

Guage Swap

83 did a great job on getting this info:
https://www.yotatech.com/forums/f114...e-swap-164182/

Originally Posted by 83
Part of this was posted by others over at the Marlin site, but I added to it & figure we could use our own swap thread over here in the pre-84 area. I think '79-81 trucks are different, but if you have an '82 or '83 with the "newer" style gauge, this will work.

**EDIT: The person who made this list came up with the numbers by counting every slot in the plug. The FSM numbers them differently because it only counts slots that have a wire in them, so don't try to compare the two or you'll get confused like I did!
It also seems better to use the wire #, as opposed to color, since some seem to be different. I'll post at the end of this thread what wire color I've got in what #slot. For that part I used the numbers from the FSM, not from this list below. Feel free to post here or PM me with any questions.

SR5----------Non-SR5---------Wire Color----Function

1<-----------------1-------------->GY------------>Right turn signal
2
3<-----------------3-------------->BR(B BR)------->Speed Sensor (-)
4<-----------------6-------------->GL------------->Speed Senson (+)
5
6
7<-----------------23------------->YG-------------->Water Temp
8<-----------------9-------------->RW-------------->Panel Lights (+)
9<----------------15-------------->YR--------------->Fuel Gauge
10<---------------12-------------->Y---------------->Ignition switch power
11<---------------21-------------->YB--------------->Oil Idiot Light
12<---------------22-------------->YW-------------->Charge Light
13<---------------14-------------->WB-------------->Ground
14<--------------------------------------------------Tach-must run a wire
15<---------------17----------------GB---------------Left Turn Signal
16----------------16----------------RB---------------Panel Lights (-)
17
18
19<---------------11---------------G-------------------4wd
20
21<---------------19---------------BY------------------Seat Belt
22
23<---------------13---------------RG------------------High Beam
24<---------------20---------------GW-----------------Brake

So if you get an SR5 cluster and simply plug it in to your truck, any of these wires that aren't the same number won't work. When I just plugged my cluster in, the right turn signal was all that worked. So you need to pull the wires from the corresponding number out of the plug and re-insert them into the SR5 location.


This shows what the back of the cluster looks like and the wire numbers. It also, if you can see it, shows you where the separate oil & volt cluster hooks in.



So to get the oil gauge & voltmeter working, you need to splice into the main cluster wires. You could get away with just splicing into hot wires here and there, but I liked doing it the way it would have been if it had been wired for it from the factory.

Back of gauges


Cut & labled


Connectors


My voltmeter ended up having some different wire colors than the FSM page listed, but they were all in the right location in the plug, so it was easy to figure out.
What I came up with after looking over the diagram is this, as far as what wires to tie the mini-cluster into:
Mini-------------Main
19 & 21(oil)---------->17
18 & 22-------------->6
21(volt) & 23--------->12
24------------------->Oil sending unit (SR5 model for GAUGE, not idiot light)
20------------------->Ground

Notice there is a #21 in each gauge for some reason.

If you want the oil idiot light and gauge to work, you need both sending units; one hooked up to the main cluster (switch), one hooked up to the new oil gauge (gauge). I just left the idiot light out..

Splicing into main cluster


Connecting to mini-cluster (I used 16 gauge wire)


I'll need to pull the part that connects the wire to the oil sending unit off a truck in a junk yard & splice it in, but for now I just have the wire wrapped around the sending unit and it works fine, but I'm guessing it'll eventually vibrate off if I leave it that way. That's it, mine works great.




***Here are my wire color locations (using the FSM slot #'s)

1___2___3___4___
G___BY__RG__GW

5___6___7___8___9___10___11___12
YR__Y___YB__G__WB__Tach_GB___RB

13___14___15___16___17
GY__Br____GL___YG__RW

Remember, B is black, Br is brown, L is blue.

how they work:

https://www.expeditionexchange.com/equal/ check these out. We used them when I did tires and they work awesome and are a lot cheaper! And they really do work for the life of the tire. There are different sizes of bags for different size tires but theyre awesome. You just toss the bag into tire before it's mounted and the bag dissipates once you start driving and the material locates where it needs to go. Really works. double checked it on the balancer every time and it zeroed out ever time.

I ended up with a rear tank from a '93 F150. It measures 34.5" x 26.5" x 8". It looks exactly the same as the one Harry put in his truck, but I never actually measured his and I'm not sure he did either. I'm not sure it holds 22 gallons, seems too small.


the ones I found from Ford vans looked like the pictures clutter1 posted and measured 34" x 23" x 11". This one is probably the 22 gallon one (definitely holds more than the one above anyway). Good size, but thicker than I wanted.

The F150 tank is nice and thin and shouldn't hang down much. Its actually a little less than 8" thick at the thick end, and the other end is closer to 7". Unfortunately, putting the thin end towards the rear to minimize dragging also puts the filler on the wrong side. I guess I'll see how it works out...
Hopefully this info will help somebody.

Talking 1st Gen Head light conversion: Rectangular to Round (or Vice versa)

OldDirtyDirt did a nice write up on converting square to round headlights
This can be used to go round to rectangular too..
Parts you will need:
-two headlight aprons (doors, bezels) of the kind you want
appropriate grill (79-81 grills are not compatible with rectangular headlight -aprons and vice versa with out hacking stuff up)
-2 headlight buckets (round or rectangular)
-side marker lenses (again they are specific to the headlight style)
-head light lenses assemblies (now is a good time to updgrade to H4 style housings)









Side marker lights will need plugs swapped:

Differential breather extension/part numbers

Been meaning to post this for awhile, a recent thread reminded me:

Nissan Part number 38323-C6010

Toyota 90404-51319: for 3/8” Barb
Toyota 90404-51026: for 1/4” hose
Nissan 38323-C6010: for 3/16” hose

or a standard 1/8" NPT to 1/4" hose barb fitting. as 4crawler mentioned it's not a perfect fit but his worked well.

Toyota part number for the OEM breather is 90930-03031

Didn't want to quote the whole post to get the information across, but this is in reference to the L50/52 scenario...

L52's were NOT an 83 model year only transmission!!

The engine data plate in my 81 that I just sold last week very clearly stated that it was factory equipped with an L52 transmission.

Door Hinge Pin replacement/Quick Release Door mods

consolidating some info on door pin replacement and quick release hinges for half doors or tube doors:

wheatus did a nice write up on replacing door hinge pins

Originally Posted by wheatus
It seems that you can purchase lower door hinge replacements but not upper hinges. I modified my hinges to use replacable pins and bushings. To do this modification you will need: 12mm socket, ratchet, at least 3 inch extension, files or grinding tool, hammer, punch, vise, hacksaw, and a helper. (I will try and get the part numbers of the pins and bushings i used. I took my hinges to the parts store after i removed the old pins and bushings and found something close.)

1. Roll down the window, it makes the door easier to handle when removed.
2. If not equiped with power windows or locks skip to step 4.If equipped with power options you will need to remove the kickpanel and disconect the wiring.
3. Pull the wiring through the A pillar.
4. Using the ratchet, extension, and 12mm socket remove one bolt from each hinge.
5. Have your helper hold the door as you remove the last two bolts.
6. Remove the 4 bolts holding the hinges to the door shell. There should be a total of 8 bolts.
7. Place the door shell in a place where it will not get damaged.
8. Take pictures or mark the hinges top and bottom to aid reassembly later. Work on one hinge at a time so you do not mix parts.
9. Secure the hinge in a vise.
10. Using a flat file or a grinding tool, a dremel or a die grinder work well, to grind the puddle weld holding the pin. Be careful not to grind too much off of the hinge.
11. Use the punch and hammer to knock the pin out of the hinge.
12. Remove the old bushings.




13. File, drill, or grind the hinges to fit the new pins and bushings. Notice that not all of the holes are the same size, check the fitting often.



14. Line up your marks or refer to your picture for reassembly.
15. Install new bushings.
16. Install new pin.
17. Reassemble the hinge.



18. Using the hacksaw you can cut off the excess pin. (optional)
19. Repeat steps 8-18 for the other hinge.




20. Reinstall the hinges to the door shell.
21. Have helper hold the door as you mount the hinges to the body.
**If you go this route, use the hinge version of the right, not the left***

1st Gen Plug Differences: 79-81 vs 82-83

so just because you have a 1st Gen truck, there are differences between the 79-81 and 82-83 that are not as obvious as the round and rectangular headlights;
Found this when swapping steering columns today:
the light/wiper switches look the same-

81 switch plug in on top, 82-83 is on the bottom


I will try to post more plug differences...

I am very interested in this. Ive always wanted to put intermediate wipers on my truck. I hate the only low and high option. I wonder if there is anything else than to just swap the controls.

that is something I am not sure about..., there are 21 pins on each connector...

Tuning a weber 32/36 series Carb

From this thread:

NOTE: This ONLY goes for the 32/36 DGV/DGEV/DGAV etc series of carburetors not the 38.

This procedure assumes no modifications have been done internally to the carburetor. Including but not limited to primary and secondary main jets, air corrector jets.

It also assumes you have no vacuum leaks ANYWHERE including the popular two-piece adapter that typically comes with the kits. I HIGHLY suggest using the Transdapt 1 piece adapter. Others have had decent results with the LCE spiral adapter as well, even though that is also a two-piece unit. Easy way to test for vacuum leaks at the adapter is to spray carb cleaner in and around the entire base of the carburetor. If a change in idle (usually a stumble) is noticed then the adapter is leaking air into the engine and needs to be fixed before any accurate tune is achieved.

Other common areas for vacuum leaks are Valve cover gasket, oil pan gasket and timing cover gaskets.


Carburetor Set Up and Lean Best Idle Adjustment



Base line Settings
Speed Screw 1 to 11/2 turns
Mixture Screw 2 turns
Your settings with engine running
Speed Screw ____________
Mixture Screw ___________




It is important to follow all linkage and lever installation instructions. The number one and two reasons for tuning errors are improper linkage installations and over tightened linkage nut, causing a binding in linkage assembly.

CALIBRATIONS MAY VARY DUE TO REGIONAL FUELS AND STATE OF ENGINE TUNE AND PERFORMANCE. POOR RUNNING QUALITY DOES NOT MEAN A DEFECT IN THE CARBURETOR. AN ADVANTAGE OF THE WEBER CARBURETOR IS ITS EASE OF ADJUSTMENT AND TUNING.


SET UP ADJUSTMENTS

Start set up by confirming carb base line settings. Do not depend on the factory delivered settings. Check them before the carb is installed.

All settings are done with choke disengaged or warmed up so that the choke is fully opened and disengaged. This is done on automatic choke carburetors by first opening the choke butterfly by hand and inserting a wood block or wedge of some kind to hold open while the linkage is cycled (linkage operated through its full movement ) to clear the choke cam. (You will hear a metallic click as the cam is released. You can check the fast Idle screw under the choke assembly to confirm that it is not in contact with the choke fast idle cam.)

Set the Idle stop screw (speed screw see fig 1) by backing out the Idle speed screw until it is not in contact with the throttle stop lever. Cycle the linkage again to be sure that the linkage comes to close without any assistance. (Checking for linkage bind) Now bring screw back into contact with the lever and continue to open or screwing in 1 turn no more than 11/2 turns.

Set the mixture screw (see Fig 1) by first screwing in until the screw stops, bottoms out.

DO NOT FORCE OR BIND AS THIS WILL CAUSE DAMAGE TO THE SCREW AND IT’S SEAT IN THE BODY OF CARBURETOR.

Back out the screw 2 full turns.


TUNING
  • BE SURE TO FOLLOW THE NEXT INSTRUCTIONS IN THE PROPER SEQUENCE, DEVIATION WILL CAUSE THE CARBURETOR TO NOT FUNCTION TO ITS IDEAL SPECIFICATIONS AND MAY NOT PROVIDE THE PERFORMANCE AND FUEL ECONOMY AS DESIGNED.
  • Start the engine, the engine will run very slowly more like a tractor. As long as the engine stays running idle speed is not important at this point.
  • The first thing to do is not set up the idle speed, but to set the Idle mixture screw to lean best idle setting. First, turn in the mixture screw until the engine dies or runs worse, then back out the screw (recommend turning ¼ to ½ turn at a time). The engine should pick up speed and begin to smooth out. Back out ½ turn more, or until the screw does nothing or runs worse then turn back to the point where it ran its best.
  • Use your ear, not a scope or tuning instruments at this point. You want to tune the engine by sound. Adjust to best, fastest and smoothest running point.
  • Now that the mixture screw is at its best running location, you can adjust the Idle speed the screw. The screw will be sensitive and should only take ¼ to ½ turns to achieve the idle speed you like.
  • Check and set idle to your driving preference. Put the car in gear and apply slight load, (AC on) and set the Idle as you like it. Don’t set it too high, as this will cause causes excessive clutch and brake wear. The Idle only needs to be 7 to 900 RPM with light load or AC on.
  • Recheck timing and vacuum hook ups. Recheck mixture screw to lean best idle again. If all is still best and smoothest idle then confirm and note the final settings.
  • To confirm settings with the engine running. Start by screwing in the mixture screw and count the number of turns it takes to bottom out and note if the engine dies. If Idle Mixture screws are with in ½ turn of base line setting then all is well and have fun. Also check the speed screw and note how many total turns from initial contact. You may have opened (turned in) the speed screw. Your final setting should be under 2 full turns. Reset the screws (back in) to the best final settings (Per your notes) and go on a test drive and have fun. If the settings are other than described then you may want to recalibrate the Idle circuit (low speed circuit) to your engines needs. This is done by following the rule of thumb BELOW.

Simple Rules for low speed calibration
If the mixture screw is more than 2 1/2 turns out turns then the Idle jet is too lean (too Small). When the mixture screw is less than 11/2 then the Idle jet is too rich (too large). These assumptions are based on the fact that the speed screw setting is not opened more than 11/2 turns. If the speed screw has to be opened 2 or more turns then this is also an indication of a lean condition usually requiring greater change. At times it may appear to be showing signs of richness or flooding it is really a lean condition. See pictures and notes in the tech 2 article supplied in the kit instructions, view and please understand the need to keep throttle plate as near to closed as possible so as not to prematurely expose the transition holes. This is what causes the visible rich condition, and confirms the need to increase the jet size.

JET KITS are available if needed.


EXAMPLE: With the speed screw set at no more than (1 1/2) turns in after contact with the stop lever; and the best idle occurring with the mixture screw set at 3 turns from bottom, indicates the need for a larger Idle jet. Achieving the best idle at under 2 turns indicates the need for a smaller idle jet.

The secret to understanding the critical nature of the carburetor set up and the advantages of a WEBER over other carburetors is the Idle circuit. Referred to as the low speed circuit by Weber, this circuit is responsible for 80% of the driving operation. This is the reason that the Weber should give a fuel economy improvement over most factory carbs along with significant performance gains. In the worst case you should not see a significant fuel economy loss over stock, while improving HP & Drivability.

The Weber Carburetor is a sequentially timed device to the motor like the distributor. Time taken in the setup will provide more fun later.

" http://www.redlineweber.com/html/Tec...lean_best_.htm " That's where 99% of that info from that thread came from. But I know I have answered that question so many times about how to tune it and how to pick which jetting etc etc. Thx ocdropzone. I'll add those other links as well to that thread.
