If wheel seems fine, remove the wheel and then you can access the backplate bolts etc. I don't have repair guide for KKK (I have done several Holsets and Schwitzers), but it would be useful so you can check the factory tolerances for rear seal groove wear limits etc.

Here are few links you might find useful:

Repair guide for KKK:

Reviving an old thread...

Where can one buy a quality k27 rebuild kit?

Still debating rebuilding mine... while I’m in there... motor was fully rebuilt just putting on the final pieces... turbo has some slight play, fine oil mist in intake...

Does anyone have a link to specs for normal end play and axial play? For all I know it’s in spec, 65k miles, not sure if rebuilt before...
