No oil pressure. How did I screw up?
I replaced the oil lines on my '84 FXR because it started leaking big time & meanwhile the hoses were over 30 years old. I had to pull the oil pump because it was in the way of a couple of fittings. No oil pressure after I reassembled - no suck at the gravity feed inlet, no blow at the return. The gears on the high pressure side of the pump turn when I crank engine but pump does not seem to be working, even though it was working before I took it apart. Yes, I put back the 2 woodruff keys when I reassembled, and replaced both gaskets using no sealant.

Yes, according to the dealer manual for that year. I triple checked. However, I just discovered that I am supposed to prime the pump by following this procedure: 1st take the plug out. (with the check ball)crank motor till oil comes out,replace plug,take out plug where tappet screen is,crank till oil comes out out,replace plug.crank motor about 30 more seconds to oil thru lifters and your ready to go.

So okay, removed the plugs one at a time and cranked and cranked. Finally I dumped in oil in the plug hole where tappet screen is until it overflowed and cranked it. Finally the output port of the oil pump started spewing oil, so I guess that's it!
F*ck me. Oil spilled everywhere, it took many hours altogether, and I'm still not ready to test it until I finish putting the bike back together. But I DIDN'T screw up really, I just didn't know to prime the oil pump by dumping oil in the uppermost plug hole until it overflowed.
