One shot grease

Hi, what's the general consensus on one shot is it still drain old oil and pump in grease or leave whatever oil is in there and pump grease in

iirc the later hubs didn't have a drain port - just a fill port....now here's the fun, there are also two later hub styles I think....one with a lower fill port which is also the level port, so just fill till it dribbles out....the other has the fill port higher up and is designed for the one-shot grease hence why there is no need for it to act as the level port too....as the one-shot is pre-measured.

I used One-shot on our previous 1991 110 with no issues and our current 1988 110 I have used oil....again, no issues....

Some say that with the earlier Railco top bush, one-shot is not thin enough to make it through the little lube hole to lube the top bush....whether there is truth in this or not I don't know!

Hows that for mudded waters!

Its good stuff and does work fine in the older motors with no issues I can see.

Ok thanks , got some on order
