Engine/Transmission (1994 - 1998) clocking turbo

[btanner]

I know that on bigger trucks that you can loosen the housing and rotate the housing. I am having some clearance issues on my truck that would be resolved if I could clock (rotate) the turbo and intercooler intake up. SO is this possible and if so what exactly should I look out for. I'm sure that you don't want to take it complete apart because of the shims and such on the turbo. Thanks for any help

The Hx35 or 40 are very easy to clock,take a little pressure off the snap ring and turn away.

Or you can loosen the (4) bolts that connect the compressor housing to the exhaust housing.



Much easier especially if you dont have a large set of pliers



no shims, just make sure everything is bolted tight and make sure the turbine spins freely and if its a new turbo preoil too.

If you rotate the center section any more than a little the oil drain will not be correct

I understand that

It SHOULD be an easy job if the tabs on that snap ring are parallel or, better yet, bent slightly away from each other. On mine, they were bent a little toward each other. Every pair of pliers, vise grips, etc. I had would slip off. I finally used my dremel tool and a ball-shaped grinder to grind a little divot in each tab. Then I modified a small spare C-clamp to have points instead of flat surfaces at the clamping points. That worked real well to squeeze the tabs and loosen the snap ring. It was kind of a lot of fooling around to simply clock the housing. But it was all I could think of at the time.



Piers told me, whatever you do, don't let that ring jump out of the groove. It can be a real pain to get it back in!

I had to "clock" mine just alil bit when I replaced the turbo. I loosened the 4 bolts and rotated it.

When i installed my new PDR35 I clocked mine a little wrong and had a hard to find oil leak that was from the return line into the rubber hose. I reclocked by loosening all 4 bolts and rotating, piece of cake.
