730d transfer diesel pump

[KENWORTH]

hi all, need some good advice. my transfer pump seems to weep fuel. i install a new mounting gskt and it seemed to run better and the fuel leakage stopped for a while. it now still seems to weep fuel, but not as much. i think it runs not as well also. can these transfer pumps be rebuilt or replaced? thanking you all in advance. bruce.

The gasket is only used to keep any slung motor oil from the governor side from getting out. The pump is kept tight and dry by two lip seals inside on the shaft on either side of the weep hole. Yes, they can be re-sealed, lots of folks repair them. I had my last one worked over by Albert at Renaissance Tractor, Chealis, WA. The pressure has to be in the correct range or the injector pumps will not fill in the proper time and the tractor will lose power at times of full fuel demand.
