What type of Turbo is this?

[gasser]

I know the pics maybe hard to tell exactly, but I would like to know what Turbo this is. This is on the M109A3 I purchased from GL. The engine is a Hercules LDT-465.

All I have to go by is the pictures right now ... I haven't seen the truck in person yet.

Any ideas?

Thanks all,

Looks like the "D" to me. Smaller diameter, fatter exhaust housing.

If I had to be lunch on it, I'd bet it was a "D" turbo. The "C" turbo usually has the 3LG319 cast in the compressor side of the housing. Just for kicks I went out and was comparing turbos out in the yard. The known whistler on the tractor didn't have the 3LG319 cast in it but trust me, it's a whistler. Then I went an compared it to 2 take off turbos. Thought both were D turbos. One thing I noticed, the "C" turbo on the tractor and the 2 take off turbos had a date cast in the compressor side of the housing. The one known "D" turbo I looked at did not. As soon as I dry off a bit I'll go out and check the other known "D" turbo in the wrecker and see what it has. Thought I knew quite a bit about turbos but after today I know evel less.

yes sir that is the "D" turbo. Get like one more PSI out of it but no wine of the turbo.. but that could be nice sometimes.

OK, just went out and had another looksee at the 5 turbos here at Casa De Recovry. Seems to me that the key is (and I've been missing this) is the exhaust side of the turbo. Reaching inside the fenderwell and stretching a tape across the side of the exhaust side I came up with this. The "D" turbo in my wrecker and Mike's deuce measured roughly 3" in width. Off to the tractor and did the same measurement and came up with about 1 1/2". Also checked the ventilated engine and the other turbo in the van body and both are 1 1/2" approx. I've always looked at the compressor side trying to see the differences and should have been looking at the exhaust side. Guess I need to stop complaining about not being able to find "C" turbos, I've got 2 besides the one on the tractor. Perhaps on my next day off, I'll be swapping turbos on the wrecker.

Also, I may get this backwards, the exhaust housing on the D is held on by four bolts and the C is held on by a clamp.
