So I haven't seen this come up before, but knightops on another bike forum may have seized his 850 motor after a rebuild. Are these pumps self priming, or is there a way to get oil into the pump without splitting the cases and doing it manually?

If the impellers in the pump have oil on them the pump will prime itself. I think there was another problem.
If the bearings were lubed upon assembly they would have been fine until the pump picked up.

I have not purposely opend the pump and cleaned every drop of oil out of it, but I have had the oil pump screen off and drained every drop that would drip from one before. Reinstalled it dry as that would get it, and never had an issue with the pump not priming and pressurizing.Life is what happens while your planning everything else!
When your work speaks for itself, don't interrupt.

The clearances in these engines are pretty tight and typically even if the oil pump is completely dry there is a film of oil left on bearings. I would suggest that if someone is putting an oil pump that has been removed and reassembled that they manually check it before installation and that way when they reinstall it it will be primed I'd never depend on the dummy light to ensure lubrication got there. Any engine I reassemble and install all bearing and gear assemblies with assembly oil. I want to rotate the crank and pistons’ feeling bearings and gears for binds etc.
I would imagine that if a person was worried that they may be able to pull loose the oil tube going from the head to the engine and make an adaptor to back pressure oil with a syringe. Possibly if in doubt you could remove the plugs and remove the same line and hit the starter till oil came out but what a mess.To fix the problem one should not make more assumptions than the minimum needed.

I don't think he even got it started did he? It stopped turning while cranking I thought.Greg

My experience is any non-submerged oil pump has to have some oil ran through it before assembling onto the motor. If it was disassembled/cleaned then installed dry (or with only a slight amount of oil in it), they won't self-prime.Fast, Cheap, Reliable... Pick any two

I should have been clearer in what I meant... if the pump is submerged and will fill with oil via gravity (not the case with the XS pump), then you don't need to prime them. I'm with you, I always pour some oil through the pump to make sure it's primed...Originally posted by BA80 View Post
