i recently heard aboute the silencer ring you guys have been talking about so i decided to take a look when i removed the front turbo intake boot i noticed some oil spray not a lot but enough to notice, I know from working on rigs at penske TL a bad turbo can mean big trouble seen trucks run on oil!. so what should i think aboute this. the shaft has no end play just a little up and down not much, the oil worried me though, I think im going to back down my plate tommorrow just incase it is the turbo dont want to big of a pocket buster any help would be great truck is in service every day. every day counts

thanks brendan white

 

Contact the folks at http://www.htturbo.com/ for a rebuild kit, about $75

 

looked at web site relativly cheap how hard is it to do or mess up! has any one done a rebuild kit befor or is it worth geting an hx35 from piers for $650.00

 

Are you sure the oil did not come from the K&N filter?

 

Go to the Holset site and download the instructions. You'll have to Google it as I did not save the page. Not too bad to do. Mine is due but I just have not found the time yet. ANY side play is not good and may weep oil. A good point was brought up by hayseed, do you have an oiled filter element? A lot of people over oil these and the turbo will suck the oil out of it in time. Another thing is remove the lower boot going to the intercooler,,look for oil in intercooler. If any there it has been weeping for awhile.

 

you know i was thinking the same thing aboute the k&n because i had just cleaned it not to long ago but not sure though i will keep a close eye and ear on the situation and keep up with the posts if it is im going to get an HX35 from piers I did have the boot off by accident (blew off on a hot run down the road the other day man what a noise i almost craped my pants) but did not see any oil down there when i was puttin it back together.


thanks for the info with out this FORUM id be #$%& up creek this is the best thing iv ever found on the internet thanks to all

 

B'

I had the exact same thing when I ran a K&N. It was new from the box and coated both the turbo and intake hose from the air box with a film of oil.

 

You have it backwards, slight side to side play is allowable, front to rear isn't.
Side to side 0.013 - 0.020
Front to rear 0.001 - 0.005

hown would i go about mesuring the play or do i just visulize what it would be and determin from there eaither way it is deffinitly a little wore i haul some heavy equipment and its just my luck ill be towin a bobcat or somthin and have the thing start drinking oil for dinner

 

Dial indicator... As posted above, side to side isn't bad - it's front to back that's the problem. The fins aren't hitting the compressor housing when you wiggle it side to side are they? If you really concerned, you could have HTT rebuild it for you too. If your in a hurry and can't have the truck down for a couple of weeks, overnight ship the center section to them and have them check it out and overnight it back to you. Only delay is if they have a backlog. Call HTT, they'll guide you and sell you only what you need.

 

My method is crude but works.
You can feel the allowable side to side by wiggling it but shouldn't be able feel fore to aft.

 

Thanks for the correction infidel. Learn something everytime I read the forums!!
