Here's the deal... I have an Onan L634T (same as a Cummins 6A3.4T). It is not a dodge-cummins engine... it's an old UPS truck engine. It's going into a Land Cruiser.

I am attempting to install the "rear main seal wear sleeve". A steel band that goes on the tail end of the crank. There is pretty much no way to do this, without having the Cummins Service tool "Oil and Wear Sleeve Driver", part #3823420.

This tool is discontinued.

I brought the motor to Cummins West, they said they could do it. Now they say they don't have the tool.

Does anyone out there work on these motors? Maybe an older UPS mechanic (they stopped using these engines ten years ago).

any help would be appreciated.

(this is also on POR, sorry for the cross-post, but i am up a creek)
 
are you talking like a speedi sleeve? what about getting something from one of those kits?

Or what about having a machine shop make the tool or what about making your own tool.

You might also try heating the sleeve in an oven then sliding it on the crank after it's good and warm. Should open it up enough to let you slip it on before it cools but you have to be quick about it...

i tried the heat in the oven... i got it half way on. then it wouldn't budge. i needs to go about 1.5" over the crank. but, in any case... problem is solved. Cummins West finally found the tool... so now it's finally time to do the conversion.
