t3 rebuild
 

i have a .42/.48 airesearch t3

i was thinkin about rebuilding it since it has quite some shaftplay

i started to take it apart but i have trouble taking off the wheel.
i took off all 6 bolts to remove the housing, i then took off the 4 bolts near the oil feed.
i was told that the wheel should slide out after those bolts, but it doesnt!

what am i doing wrong?

how do i get the wheel off?

Blaast is going to tell you that you shouldn't disassemble it. He's probably right.
When you take it apart (or put it back together) you need a T-handled wrench, otherwise it's easy to twist the turbine shaft and perma-jack-up the setup.
If you take it apart you need to pay attention and mark how the compressor is oriented to the shaft. They're balanced together for a reason.

Most HMTs won't notice too much shaft play until there is contact with the housing. Once there is contact with the housing, all bets are off as things aren't going to balance right, nevermind being damaged and won't perform correctly. To be able to do a "simple" rebuild, you need to get to that turbo before there is any contact or binding... Basically while it still functions fine, but is out of spec.

Also, once it's out of spec, the rings wear the center housing quickly... May not seal right again.

BTW, if it's been rebuilt before, it may have non standard sized bearings, seals, turbine shaft.. etc..

You guys are reading in my mind but let's narrow down all the reasons for not attempting a "home made" turbo rebuild to the simple fact that the result will not be warrantied. if you have it rebuilt by any profesional turbo shop equipped with the necessary tools (much more than just a T-handle!!!), the result should be warrantied so in case of problems, you are covered.

throughout the considerable amount of turbos I rebuilt for HMT fellows in the last years, i had to send replacement chras under warranty a few times to trouble shoot sturdy problems. in most cases, it just confirmed the turbo was NOT the problem but still, it was a pleasure to do it.
