View Full Version : D8 water pump problem

09-17-2013, 09:21 AM
Need help: Water pump leaking on D8 8R. Frame #8R 9605, Engine #8R9605. The water pump is not the one shown in my books. There is no easily accessed packing nut to tighten. It is more of an enclosed type where the shaft is hard to see. The part number on the main housing/casting is 2H4729.
I got the pump mostly apart but there is what appears to be a faulty seal. I cant figure out how to remove the seal, and what is the part number so I can start looking for it. This pump appears to lack any means of tightening any type of packing.

Probably got changed out for a late 2U pump.
Does it look like this?
Just looking at it quickley, looks like the impellar needs to be removed and the shaft/bearing assembly pulled out to access the seal.

Yes it does look like that. Now that I know what I am looking for I can start looking for seals. I'll try Florin tractor in Sacramento. Thank you very much for the help.
