I got a chance to see CarolinaTurboT replace his stock turbo with a TE-44, today. When we examined the (old) stock turbo, there appeared to be a few thousandths of endplay in it. I was wondering if this is what's considered to be beyond tolerance for use. Thanks.

as I recall, if you can feel the shaft move in and out, that is too much?

Best to call John Craig at Limit for a good opinionm, tho....

Thrust bearing movement is .003" from the manual.

Radial movement, up/down of the shaft in the middle, must be between .003" and .006". I didn't realize there was a good section on the turbocharger in the service manual.

Got it. Man, the turbo didn't have that many miles on it and he obviously doesn't mistreat his car. Can common radial force (boost to decceleration) have that much wear and tear on the thrust bearing? I'd say it was a bit over that .006 tolerance. He also had a little oil in the compressor side.
