transaxle rebuild thread?

[BFB]

i think im going to attempt my 1st transaxle rebuild this winter and wondered if there might be a how to sticky somewhere?
yes i do have a jig a few other vw trans tools, and i know i have some old vw books too that might have the process in them but i doubt they have any info other than stock rebuild.
thanks in advance

An interesting thing happens in forums where everyone starts parroting the same thing and "common knowledge" takes over.
Most experts aren't.

This was my old thread of just an average guy trying to build his own transaxle... not a how to, plenty of mistakes were made. It may help you along the way or at least familiarize you a little.

I have asked about interest in posting a trans build thread, didn't get much interest in it. I am more than willing to answer any questions along the way.

There's at least one thread in the Vanagon section if I remember right done by Gears, it will be a late bus box build with a lot of oiling mods.

In this section you could follow this one if you have a type 1 IRS
https://www.thesamba.com/vw/forum/viewtopic.php?t=...mp;start=0

Long Enterprises might still have their website up and have a free disassembly of a swing box on it.

Swing/ IRS/ bus box you don't have to have every single factory tool to rebuild them. VW went kind of nuts with the special tools at times and there are work arounds for some of them and others not really used at all by rebuilders.

Start a thread and there are plenty of people that can guide you through it if you get stuck.

I've always thought The Samba need to separate Engines and transaxles into separate forums.

it would be nice if we had a few more forums or sub forums. transaxle forum, electrical. a drag racing forum. autocross. formula vee. or even just a racing forum,

Personally I'd love a good walkthrough of a more or less stock transaxle rebuild, that's one of the few parts of VWs that I feel intimidated by.

Parts, and tools are the biggest hurdles in rebuilding transaxles imo.

We’ve gotten spoiled in a sense that we use the distributor drive gears that are og VW in an engine, and everything else is available new at various quality levels at prices that aren’t too harsh on the wallet. Sure, there are components available to build an entirely new transaxle. There are nos parts “stashes” that places like Weddle find, and are gracious enough to offer them at fair pricing, but new replacement parts are mostly high end performance parts at high end prices.

Like esde mentioned, a stock rebuild is simply replacing parts worn out of spec with parts that aren’t. It’s when you want to replace something as an upgrade, or replace a NLA part with a more commonly available later model part is when you can get into trouble. Something as simple as needing to replace the differential bearings in a swing axle can then change the bearing pre-load/gear backlash that would then need VW tools, or ones fabricated to function as the VW tools to reset. The next issue is having the shims to adjust the positioning of the diff within the bearings to reset the preload/backlash. One extreme is the current S/A in my personal 67 Beetle has parts from 5 different transaxles ranging from 61-79 from both Type 1/Type 2. Another extreme was when I was able to do a budget rebuild for a 63 transaxle with og replacement parts after getting three loaded gear carriers with all replacement parts needed for $10 each in a trans core buy, and the cost of some gaskets/seals.

I get it. There are those mechanically inclinded that would like to know what’s inside. Casting Timmy, and anthracitedub are the only two I know of in the performance forum in the 17 years I’ve been a member to tackle, and follow through on getting tools/completing a rebuild. There are a few Type 2 builds in some of the other categories.

For those interested, you will basically need to...

-Be willing to spend some money to acquire the needed tools
-Fabricate the tools you cannot readily find
-Be willing to spend some money on new/used replacement parts that may/may not be readily available
-Be willing to have multiple core transaxles on hand to harvest replacement parts

I was fortunate enough to have a mentor/teacher standing over me to guide me with “that adjustment/tolerance is fine”, or “that’s not together correctly” to be able to have my first few rebuilds go well without incident once installed. If you don’t have this person, you can add to the list above,

-Be willing to remove the transaxle one, or more times to correct an adjustment, or mistake

I know of more than one person that has rebuilt an engine without the use of a torque wrench that had/have engines that ran well for extended periods of time. There are varying levels of a transaxle “rebuild”. You’re going to have to go all in to get something the level of quality Mcmscott would produce.

For those wanting to learn to “save money”, put a big rock over the rabbit hole. Unless you’re going to rebuild 3-5 transaxles, the set up costs/time investment will outweigh simply buying a rebuilt transaxle.
