Hey, guys
I'm starting to mull over going through my manual tranny when I swap out my engine. The synchros are getting a bit notchy, so I was looking over one of those bearing and synchro kits available on ebay.

Before I take the plunge, I wanted to get hints from others who might have done this before. I have checked the FSM, and they seem to require a number of bearing pullers and a press to get the gears on and off the shafts. Also, there appear to be several calibrated thickness washers that are used to adjust bearing clearance, which might have to be changed out when new bearings are installed.

To give a bit of background, I have rebuilt a number of British gearboxes (MGB and Midget/Morris), and I also took my 1979 Toyota truck tranny apart to replace the gaskets and seals (but I did not take any of the gears off the shafts or out of the main plate, just pulled the bellhousing and casings off).

I just don't want to get into a situation where I am dead in the water for lack of a puller or press. What do you think?

Cheers,
Paul

I rebuilt a 4Runner 5 speed years back. I believe it was from a 90 model. It was not too bad as long as I kept everything it perfect order when disassembling it. I had never done one (other than my 80s 944 trans) and it came out perfect when done. I ended up replacing several bearings and all of the synchros. It'[s a bit of an advanced job, but a rewarding one when finished.

Before you go that route, replace the shifter bushing (www.marlincrawler.com has an OUTSTANDING poly replacement that beats OEM by a mile) & if you aren't already using it, switch to a GL-4 synthetic gear oil such as Redline MT-90 or Amsoil 75w-90.

GL-4 only!!! GL-5 doesn't work well with Toyota synchros.

Thanks, Zembonez
Did you need any special pullers or presses, or were you able to get by with brass drifts and such to get the gears off the shafts?
Cheers,

Anytime you work on a manual trans it's a good idea to have a puller available to remove bearings, gears etc. Even parts that could be driven off by impact really should be pulled off to avoid damaging them... especially if they are going to be reused (as many are). A really good pair of snap ring pliers normally comes in handy too.

Thanks for the info, guys
I replaced the shifter bushing and seat about 20K miles ago, at that time I changed out the gearbox oil for Amsoil 75W-90 GL-4. It helped a lot, but I still think the synchros are getting a little long in the tooth. I've got the snap ring pliers, so I'll start hunting around for a set of bearing pullers.

Cheers,
Paul

Nope, the r150's were used in the V6 trucks. I am a bit mystified as to the exact designation of my trans. My door sticker says the truck has a build date of 1/93, but the trans designation is W55. Most parts resources seem to indicate the W55 wasn't available as late as 1993, by then they used a W56 or maybe even a W59. I still need to do more research.

My conundrum is timing. Rebuilding the trans along with the engine R&R will mean the truck will probably be out of service at least a month (given my penchant for cleaning everything before it goes back in). The ideal situation would be to obtain a second tranny to rebuild ahead of time.

Cheers,
Paul

Yes. That's exactly how I am. That's why i am looking for one to build and have ready to bolt up once I pull mine out. I have the v6. From my understanding all those w series are interchangable. I have to find an r series.

Marlin crawler I've never heard anything but good about.

Pace place I know nothing about but would trust over autozone unless some google searching came up with bad reviews.

Autozone I'd be afraid of it being their usual quality...1 in 4 bad out of the box. or sure it's got a lifetime warranty but you're going to use the warranty every 5 years.

Hey, guys
I'm the one who started the thread (name might look a little different since my home computer dumped my login and I couldn't remember the @@#$#@@ password! Had to re-register. Why don't they have a "forgot your password" question here?).

I've decided to go with the Marlin Crawler rebuilt W55. I started looking into the special tools and shop press needed to press or pull the gears on and off the shafts, and all the selective washers of different sizes to get all the clearances right. If I were younger, I might consider buying the tools, but this might be the last trans I attempt to rebuild. In any case, they have a good warranty, and after factoring out the cost of the tools, the price of the rebuilt unit looks acceptable. My new engine is still hanging on the stand, I will probably shoot for doing the swap in the spring. I want to go through the brake system first, plus I'm going to pull the bed and replace all the rubber fuel lines (I'm getting a whiff of gas coming up between the bed and the cab after driving it).
Cheers,
Paul

Now that you're back on, shoot an email to an admin (a lowly mod like me can't mess with usernames/PW)

For which transmission, go by the build sticker. I know W55/56 were differentiated by one was for 2wds, one was for 4wds. technically the gear sets shold be interchangeable, only the mainshaft length and rear housing are different...but toyota consistently used one in 2wds and one in 4wds. I think the W59 was when they went to the new engine in the tacomas.

As for availability, I think the W55 was used in IS300s till the 2000s though that one's NOT interchangeable since the IS uses a dual mass flywheel which needs a different length input shaft.
