Cool Td04 shaft play

I had just rebuilt my td04 15t , i noticed it has a lil shaft play. It can wiggle back and fourth to each wall of the compressor housing. when i rebuilt it i marked the wheels, and installed the new bearings. I guess the shaft is a lil worn. It has no back to front play just a lil play and its making me worry =/

I rebuilt a TD04 last winter myself for my 900 vert. I had the wheels professionally balanced and marked before i rebuilt it. playing the balance by eye is Ok. you should feel just a tad bit of play in the shaft. It's perfectly normal. As long as the compressor and exhaust wheels are not scraping the housing you should be good to go.

When the turbo house balanced the wheels ($20) they also polished and inspected the shaft. You should have had a good look at the shaft. There should have been zero scoring or heavy scratching on it. If your shaft was damaged the rebuild won't last.

Just my $.02, but if its just a bit of play you should be ok.

Pour some oil in the oil supply port while turning the wheel and watch the play go away. It should tighten up pretty good...
