Default sumping

Thought I would start a new thread here to possibly get a wider scope of answers. Hope this doesn't confuse anything. So besides improper oil pump/cam plate installation bad oil pump or bad scavenger pump what else would cause sumping.

Poor seal at the interface between the oil pump pickup and the scavenge port in the crankcase. I think that was mentioned/discussed in your previous post?

Not sure if the clunk you heard is relative or not, but do you know if they checked your pinion shaft run-out, might effect oil pump alignment.

I don't know if they checked the run-out. I'm going down there tomorrow to speak with them personally. They called me today and basically said we did everything we could but can't fix the sumping so come get your bike. By the way if anyone knows of a good mech in south Florida please let me know. Some things are within my ability but this is not.

I asked you about runout in your previous post. That is one of the first things the techs should have checked. Once runout exceeds .005"-.006", the pinion will start working on the oil pump and beating out the bronze bushing in the cam plate.

I would not pick up the bike. The dealer worked on the bike and it has not operated properly since. If you pick it up, by default, you are basically letting them off the hook. If indeed they have contacted corporate, you need to get the name of there contact and verify that contact has been made and that there is a record of your problem at corporate. I would then get in touch with the local H-D rep and arrange a meeting at the dealership between you and the dealer's service manager. But I would not pick up the bike just yet.

I've been in touch with the service manager.... Sort of. It takes him a couple days to get back to me and I asked him about the run-out and he didn't know so I'm going there to sit down with the service manager and the tech tomorrow. He said the rep for our area will be down in a couple weeks and he wants me to bring the bike back then. Should I refuse to pick it up and just leave it there until he comes?

djl is giving you good advice. Leave it there till the issue is soved to its previous condition. Say you take it and rep never shows and come to find out they never contacted them. Now its a he said she said and you must ha e screwed with it after you picked it up. Leav it there. It wont take up much room.

They don't just get to give up because they haven't fixed it. Unless they want to buy it back from you under some lemon law provision.

If the pump "O" ring is disturbed, or the pinion shaft is so far out, it whipping the pump around, losing the seal.
I'd not think there is a need for any "jailhouse lawyer" advice on this, because that, is usually much more of a PITFA than it's worth.

If you are comfortable with that agreement; your call. However, that would not stop me from confirming with corporate that there is a record of your problem and I would also contact the rep to confirm the meeting.

Before you do any of that, ask the techs if they blocked off the oil passage required to be blocked off on the new cam plate. You will need a 1/4"x20x1/2" socket head screw to seal the port and the port will have to be tapped; it is the right size for the required tap and does not need to be drilled. Seems to me the techs didn't follow instrucitons. The screw (PN 94667-00) should have been included in the H-D kit. Andrews wil supply the screw at no charge.

I thought that this might be the problem but wasn't sure that the port allowed oil to flow into the crankcase. I thought it was more related to low oil pressure; just wasn't sure that this could be the source of your problem. I did some checking and, if your cam plate is an early '99, this should solve the sumping problem.

Check the link and go to page 4 for clarification.
