933G Crawler Turbo gone bad

Dont know if these guys would have a turbo or not but might be worth a shot.

Your 3S9226 is correct for the 42Axxxx.

Might broaden your search to include Turbo's from the 63Bxxxx industrial, Marine, Genset engines that also use the D320.

I can't tell you how interchangeable they are but I wouldn't be surprised if they are or at least have parts that are.

Here are some Turbo assy. numbers taken from the D320 Rack Setting Charts.

4M9129
3S5856 which interchanges with a 7M9730
5S9141, 4M9134 which also interchanges with 3S5856 and 7M9730

Good luck with your search.

Thanks for all the info.

I'm a little confused on the following

"Here are some Turbo assy. numbers taken from the D320 Rack Setting Charts.

Are these turbo's for the Rack mounted D320's?


Thanks for the search leads.

Rack Setting Charts refer to settings for the fuel injection pumps by controling the movement of the fuel rack. The settings apply to various power ratings for the application and the manual also lists some equipment required to make output requirements such as special governor applications and various turbo's.

All those turbo assy numbers are related to the D320T.

Why would they have different Turbo's and Fuel Tuning settings for the same motor?

I guess I could Understand the load differences between a Marine/stationary applications but the Turbo differences seem unnecessary.

D320 engines vary from 130hp to 54hp and 2400 to 1500 rpm, depending on application. The turbo's have a narrow operating band thus requiring various versions to make ratings at various loads, altitudes, rpm's etc.

My rack setting manual info for the 933G isn't included but penciled in is 42A5918-up being rated at full load rpm @ 1900 @ 60 hp and I believe this is for the D320T. This would be the target requirements.

The 7M9731 unit that gemdozer has was used on the 922 59A loader (and other applications I'm sure) and is rated at 2400 full load rpm and 80.5 hp.

For any other application (other than parts) you would need to know the engine serial number and it's application to track down whether an interchange is suitable.

Oldmagnet,

Thanks so much for the education. I really appreciate it. So what is the likelihood the unit Gemdozer has will have the same internal shaft, bearings etc. as my unit? I mean could it be as simple as having my 2 end pieces put on his unit?

Not that easy....the various applications are made by changing nozzles (housings) and different diameter wheels and different shaped wheels (turbines). There is a pretty good chance there is some common hardware but there is no way of knowing exactly without the part numbers. Also the applications are usually packages, with matching governor requirements and rack settings.

I'm not saying a replacement has to be exact but it should at least be close to original.
