I bought a Precision sc61 about 2 months ago..I was looking at it today and noticed a white ring on the compressor housing where the blades spin. I felt for shaft play and there is absolutely no in and out play but there seems to be quite a bit of up and down movement.Is this normal or do I have a defective turbo? When my car idles with its big injectors it pops a bit and when it does and im looking in the turbo I can see the shaft move slightly on each pop.Just curious to see if anyone else experienced this or if I have to send it in..

My precision sc34 is solid like a rock it wouldnt move a tiny bit in/out or up/down

get oil in it and see if it still has play..dry there should be a little play..

1FastCoupe

it has oil in it..im currently using it..I just don't see how a brand new turbo would have shaft play like that...

HYBRID_H@TCH

oh wow..if its on with oil in it and it has a good amount of play it might be a defect..

same thing with my gt3076r talked to precision a few times. it seem like they doesnt want to do anything about it. turbo was used for a few hours only..

Same with my SC50.

So I take it this is not normal wear. What causes this? Like i said it has absolutely no in and out play..

What does your oil return look like?

1FastCoupe

-10 straight down to a 45degree into the oil pan..It might go slightly upward before the oil pan but not noticeably upwards..

sh!tsWEAK!

A little bit of side to side shaft play is normal for non-ball-bearing turbos because they "float" on oil. My SC61 has a little bit of side to side, and I've had no problems whatsoever. In and out shaft play is what you should be worried about.

1FastCoupe

yeah a little I wouldnt worry about either but when the blades touch the front cover is where my concern is..

i just replaced my sc50 i had in for about 3 months because of shaft play. it was caused because the oil return line i used for the first month and a half had a very slight incline b4 it sloped down to the pan. this might be your cause. the problem was bad enough that it would have cost about the same to get the turbo rebuilt as it would to buy a new one.

Did you ever notice any smoke after getting on it or prolonged high revs?

We just got a brand spankin new gt40r from precision and it has alot of play, i mean u can hear this thing clanking when u wiggle it, I called them and they told me it was normal for a dry ballbearing turbo. I wonder if hes just BSing or its really true.

That's normal for the ball bearing stuff. I did the same thing when i got my first one! lol

shortyz21

if it doesnt touch the housing, its fine leave it alone.

ive heard of a few other ppl having problems with precision stuff.. poor form IMO. My gt2871r had no play at all, in and out or side to side. After 2 months, it still has none and is as tight as a muslim *****.

OK that makes me feel better haha, that thing is pretty damn loose.

its normal to have a bit of up and down and thats what mine had but it got worse until it was hitting the housing..The part that sucks is I have been reading posts about people trying to get their turbo's warrantied and Precision doesn't want to work with them..I dont think it was the oil line as the cause because I have never seen smoke nor smelled any oil burning. It must be one of those factory defects but last night it finally went it wont spin now because the propellers are now resting on the housing so we will see what Precision has to say about this. I'm sure they will tell me to take a hike and then in my opinion I won't want to use precision again. I felt a SC50 turbo's shaft play yesterday that had 2000miles on it and it had no up and down play what so ever.

1FastCoupe

fullblown, if its pretty loose that is exactly how mine felt and it lasted 1500 miles. Like I said in my previous post I tested an sc50 and there was none..
