16G bearing tolerance? FP hopefully?

well forced performance just plain won't answer me, so maybe i can get the answer from one of you guys....

my turbo is a FP TD05H-18G, and i got it with excessive shaft play. rebuilt the whole thing with a FP rebuild kit, but the compressor side thrust bearing just slides in and out of its race much easier than the turbine side. (the turbine side takes a bit of effort to slide the bearing in, whereas the compressor side will slide out if you turn it up side down, something the turbine side doesn't...)

so needless to say, there's a chance that the compressor side needs to be machined to accept an oversized bearing to get things back to tolerance...

but for the life of me, i cannot find the specs for something like this....

Forced Performance won't respond to my e-mails, they're probably laughing at me as we speak, which sucks, because besides having the turbo itself, i bought one of their rebuild kits, paid $100, got 3/4 of the stuff i could have gotten somewhere else, and more than likely didn't even get mitsu parts.

so if anyone has or knows these specs (or could toss a dial caliper on a fresh 16G CHRA's compressor thrust bearing race) that would be great.

wow, nothing?

Journal bearing bore spec is .618", and I don't find it even remotely amusing.
Try calling next time 972-984-1800 x 103 leave a detailed message and I will call you back.

well, it passes spec.... i guess the compressor side just sits a little looser?

so 2 more questions that i won't be mad if I don't get answers.

1. I pulled this little tiny square of felt off from in between the nut and the compressor wheel... is this necessary for the rebuilding of the turbo or thrown in there in say... the balancing process? it didn't come in my FP specific kit...

2. the spring plate... reusable? some rebuild kits come with it, some do not (my FP kit). my understanding is that it keeps pressure on the center plate, keeping end-to-end play to a minimum... that part doesn't wear out like say the thrust bearings?

1. That is what Loctite 272 looks like after it dries, it's not felt.
2. That is an oil deflector and it does not do anything but act as it's name applies, it is never under load unless the bearings have failed.
