Has anybody here ever overhauled their own transmission? I have an 87 Toyota pickup 4x4 w/ 22R and a 5 speed transmission. Turns out the tranny sounds like it has a bad bearing in it. Sounds like bearing in the intermediate plate for the output shaft is going. It makes noise in 3rd and 4th and when I shift into 5th the noise is much louder. Third and forth gear are in front of the intermediate plate and fifth gear is behind the intermediate plate which would change the load on the bearing and the noise it makes.

I've discussed this with a tranny guy and he told me as long as I had a press I should be able to do this. I rebuilt a 4 speed tranny out of a 76 B210. I replaced what would likely be the same bearing I will need to put in my tranny. 15 years ago I did a 3 speed tranny out of an old 63 Chevy pickup.

Anybody out there with experience rebuilding one of these? I believe it is a G52, but won't know for sure until I pull the tranny and read the 'signs.'

Any help would be great!

You are planning to install all the bearings??

I had planned to do this job but had way to much work at the time worth it to me to just have it done.

With my luck I would have lost one of the small parts or found way more wrong then I thought like chipped gears.

The my Transmission guy just grabbed the extra parts and it was done if it was at home it would no doubt still be sitting a few years later.

In fact I have 2 Transmissions and bearing kits I just never got around to doing.

As long as you have the time and the tools

 

Might as well replace the synchros while you're in it that far.

 

I say go for it. These might help you..

Bag and label EVERYTHING you remove. And take pictures if you think you may have any questions about where it came from when putting it back together.

 

Unfortunately I have a lot more time then I do money... If I am going to fix this it is going to be like everything else I will have to do it myself.

I thought I had mentioned that the syncros for 1st and 3rd are worn and need replacing too.

Thanks! Can't have too many manuals or info. I've noticed the links you given me are different then the manual I already had. http://jeep.yager.net/docs/trans-toy...air_manual.pdf

 

I have the 1987 repair manual for truck and 4runner and it shows you how to rebuild all the w and g series and automatics. It covers every thing for 87.

 

Is it the factory service manual for the whole vehicle or is it just for the transmission? Are you interested in selling it if it is the Factory Service Manual?

For the whole vehicle but it breaks every thing down for you tells you how to test every thing. The books about 2.5 inches thick. To bad you weren,t around closer i,d just loan it to you cause i,m not really interested in selling,I just got my truck and i,m still working on it. Sorry you should be able to find one.I thought i seen on here some where or it was CL here in Portland Or

 

I've been looking, just missed one on an auction for under $80... Not sure I could spend that much on one. It's a shame my 85 FSM won't work on my 87... Too much is different.

Thanks any way,

You might check out this site. https://techinfo.toyota.com/

This is an official Toyota site that has service manuals back at least as far as 1990, and some older stuff. A 2 day subscription costs $15, and you can download as many manual sections (all pdf's) as you have time and patience for. There's about 400 files total.

 

Wouldn,t the transmission section be the same? My haynes goes from 1979 to 1995 and the trans looks the same. You could probaly go to the main library in town and find one to copy.

 

This is relevant to my interests, sounds just like the issue my truck has, 5th makes a hell of a racket, 4th less as much. I don't really want to overhaul it on my own, but it'll need attention eventually.

 

Hey, anybody know if the tranny overhaul can be done without a hydraulic press? I can buy one if I have too, but really don't want to buy a tool for only one job... Kind of a specialized tool... I guess I could use it as a nut cracker when it is not being used for its original purpose...

No responses, so does that mean no can't be done without one, nobody knows, or nobody cares?

 

To do it right you will need a press. And possible the ability to make some tools. The worst part is getting the old bearings off of the shafts. I say go for it, if you cant press the old bearings off or get the new ones on you can always take it to a machine shop or transmission place and get them to do it.

 

Press, or no press, you'll need several different brass or aluminum drifts and a brass hammer. I've even got a babbitt hammer I use sometimes on things that must not be marred.
Tho I've never done one of these, I've rebuilt other kinds, and its possible that you might get it done with some soft tools, some common sense, and maybe a bearing separater plate.
Please keep us informed!!

 

Thing is, I have access to a press, but it is 8 miles away and when and if I can catch the guy there to use it. Plus, not crazy about the idea of hauling transmission assemblies across town in the family car, trying not to get oil on/in the car. Would sure feel better having the press at the house so I could use it when I needed... Just wish the press didn't cost $100...


Thanks for the replies!
