I have a 2004 Sixty-5 apart and need to order some parts. The bike pukes out oil like a big dog until fully warmed. The worm gear has a neoprene seal and seems to mate securely. I could not get the spindle to turn with the timing cover off. It would rock back and forth. I took the caps off the spindle and examined pumps and althought there was surface wear in the larger pump (scavenge) the pressure pump was pretty bad.

I thought of the Spindle but the matching worm has a cork seal instead of neoprene.

Anybody with advise on ordering, I thought of installing the high capacity pumps.

One other note is the spindle bearings look good but wea on the teeth.

I just re-read my above post and it makes no sense, sorry. I meant to say I was going to order the HC improved spindle and worm but the improved worm has a cork seal and not neoprene. Is that a concern.

I am also stumped by the fact the neoprene worm gear appears to have a good seal.

The faces of the pumps are not gouged or grooved but do not look smooth, they feel smooth. Never lapped in?

The bike has 2,400 miles on it.

Draining the front drain bolt I get over 7 oz. oil after a couple of hours.

The spindle bearing surfaces look good but with everything assembled thumb pressure will not spin the spindle.

I will assemble the pumps, plungers and spindle without caps and spring and see if everything turns without binding and report back.

Do you mean that oil accumulates in the sump after 2 hours of running or after 2 hours of being stationary?

I would say that high capacity pumps are overkill on a standard engine IMHO

Oil dribbles out of the sump drain, after around two hours 6 oz cup has overflowed.

Oil can seep through the timing side bearing into the sump and also via the big end bearing. Leaving the engine stopped with the piston at the top of the bore helps to reduce seepage through the big end.

Also don't overfill the oil tank. Halfway between min and max is normally sufficient.

There is an oil seal on the timing side crankshaft behind the timing pinion on the later 500 engines to keep oil from the timing chest from leaking into the crankcase, it might be time to replace this.
