Well I finally found a little time to work on my swap, Started modifying front drive shaft, it needs to be lengthened 3 3/4 inches

Cutting it apart in lathe


Cut apart

dmarsh4x4

Well it has been a while I had to drop a used motor in my Tacoma, 295,000 miles with the last 5,000 running on three cylinders, I guess it was time. here are some photos

I like how high this sets, I think I know what my next project is


here is the retubed front shaft for the 4Runner it was done with heavy wall tubing,


Next, I will shorten the rear shaft, with an adapter to go from the yoke to the large tube size so it will not need to be retubed

Started on the rear shaft here is a couple of photos, I should have it finished up in a couple of days.

Up date on rear drive shaft, this is why you can not just shorten a Toyta drive shaft

Drive shaft reduces in size at yokes


So you can make an adapter to increase the size of the yoke


Adapter welded on, and machining to match drive shaft ID


Press into shaft and check run out


Weld up, and you have a finished shortend drive shaft, and a couple hundred extra dollars in your walet.


If you do not have a lathe you can have a shop machine the adapter for you and still weld it up your self.

Ok a couple of pictures to catch up on progress, I pulled the tank to remove the fuel pump and it was worse off than I thought it would be


That is what is left of the pump after cleaning with pool acid and water, below is inside of tank


Anyways I was planing on a two tank system for WVO, and I would like to not have the stock tank hanging down in front of the rear tire, so I think I will fab up a tank to go where the spare tire is, it looks like I can go about 33X24X8 which will be about 27 gal. hope to start on that next week.

Here is a shot of what I did for trasfer case mount this should work for now, I did not want to get fancy here as it will be replaced and new cross member when I go to dual cases.



Other things I have been working on, wiring and mounting accessories and hoses, started on exhaust, here are a coupl of shots

Hey Dmarsh, you better hurry up before it starts snowing again

dmarsh4x4

OK here is a small update, I started on fuel tank, no pictures yet, did a lot of researching on in tank heater for WVO, I think I have decided how I am going to do it, I will post picts as I progress on the tank and heater.

Here are a couple of pictures of my throttle and cable setup

Is that the throttle control that came with your om617 or did you cobble it from other donor parts?

dmarsh4x4

That is what comes on OM617, I added the bracket to hold the throttle cable and the 1/4 circle cable guide from the old Toyota motor. Using the stock 617 linkage allows the manual stop and vacuum stop to work correctly.

Awesome work man. I enjoy your creativity in accomplishing this swap.

DMarsh,
Can you provide the plate thickness and overall dimensions (initial square) that you used to make the adapter plate? I believe it was from 6061 aluminum.
Thanks.

PowerstrokeJoe

I believe his was 1/2 inch as was mine. My initial square was 18"X18" I used steel though. Its a bit more of a pain to work with.

dmarsh4x4

Bobcat86, Thanks for the kind words

Jmorris430, my adapter is 1/2" thick 6061 aluminum and it was 17" X 17" to start with

Dmarsh when you relocated your cross member back 4" to move the tranny and tcase, besides shortening your rear DS and lengthening the front, how did you make room for your shifter setup? What about your slave cylinder lines? Any other adjustments?

dmarsh4x4

I opened up the shifter hole in the floor and put a piece of sheet metal to cover the old hole and ditched the center console, for the clutch slave I ran a new hard line to clear the exhaust

JKGen813

Ok gotcha that's what I was thinking, any other changes with using the r150 tranny that you can think of? I'm doing the swap in a 91' Standard cab. Thanks in advance

JKGen813

One more question Dmarsh, also meant to ask about your flywheel bushing adapter, would you happen to have your dimensions on that, I got some from someone else but they used the W56 tranny and flywheel and I'm not sure they will be the same. I need these so that I can be precise when trying to explain to the machine shop. I appreciate your help, just want to make sure I have everything in line before I pull the trigger.

Are you going to keep the merc oil filter, or swap to a remote oil filter and cooler? The reason I ask is Im doing a 617 conversion in my wifes 95!! I think im going to do a remote system, just out of ease of parts and mounting an aftermarket oil cooler!!


Justin

dmarsh4x4

JKGen813, I will look for my drawing I used for my pilot bushing I think it was real close to the one you have a drawing for

Justin, I am using the stock oil filter and maybe the stock cooler, if you go with a remote filter it needs to have a thermostat for the oil, i think it needs to runs about 215 deg.

JKGen813

Thanks DMarsh, I spoke with Luke at 4x4 Labs and he confirmed that the pilot bearing adapter in both his kits for the w56 and r150f transmissions are the same size, he's going to sell me one for a fifty spot I think it's worth it for the precision and piece of mind alone.

Justin, I'm also going to use the stock oil cooler and have some new SS braided lines made at a local custom hose shop, for the exact reason DMarsh mentions above.

Thanks
