Found in twincam camchest?

[BVHOG]

Ok, so I pulled down an 06 twincam camchest this morning, owner bought on craigslist and had some noise and sluggish performance. Had no idea what was done. First off found it sumping, over a quart in the cases. I pulled it down this morn and found a gear drive 551 easy start setup along with a fueling oil pump and plate combo with S&S quickee pushrods. Appears everything else is still 88 inch and never touched. Crank is only 2 1/2 thou run out. Pretty much the best I have seen in an 06 ever. lifters had some scoring on the body but pump/plate and everything looks great.O-ring was pinched on pump to case causing the sumping and inner bearings were in backwards. 
Now for the question, I found these 3 pieces in the chest when I opened it up, what the hell is/was it? any ideas, doesn't seem to fit anything and it may have a 4th piece that should have been there too. Seems to have been a sleeve or something. It's not a pivot for a tensioner and it's not a relief plunger.

A dowell pin?

Can't tell the size, but a case half dowel?

Nope, no dowel, too thick of wall, I can't imagine what it is unless the last mechanic just plain dropped something in it.

Mystery solved, it is the pivot bushing in the previous factory tensioner, guessing they got one piece out but not the rest.  I guess I gave them the benefit of the doubt that the last mechanic would have cleaned out the camchest first.

Did you ever find out why its sumping? I have an 01 that fills up with a qt or more and is slow to rev up also.

"O-ring was pinched on pump to case causing the sumping .... "

"O-ring was pinched on pump to case causing the sumping .... "

Probably because the o-ring was installed into the hole in the case first, rather than putting it on the oil pump tube and then pushing it into the case.

I've NEVER installed a TC oil pump any other way. O-ring in case, push pump into it. I can't count the number of installs I've done. No sumping ever.

I've always pressed the o-ring flush into the case, lube the pump and slide it in. I've never had one sump or leak.

I have, and why I don't do it that way any more.  Even the SM says to put on the pump first, probably to reduce the risk of cutting that o-ring.

Key word here is lube as it aids install without tearing or friction on the ring to move it out of position . Either method will work but I preferred the o ring on pump and into the case .

My 06 Dyna service manual states to put the O-ring flush in the case lightly oiled and then install pump.  That's the way I do it, takes a little care and finesse not a wham bam I am done process.  Bob

with the end of the inlet of fuelling pumps not being beveled,its not hard to pinch the O ring

[joe_lyons]

Gotta spit on it, with some good spit.lol

I checked on 07 Softail manual and it does say to install the oiled Oring into the grove in the cam chest, not on the oil pump.

Don't think it matters at all as long as you are careful when seating the pump/plate.

Perhaps check again.  You might be reading about the small o-rings, not the scavenge port o-ring.

BTW, I read that exact same thing in the SM's.  You're close to the area in the SM that talks about the scavenge o-ring.

[Coyote]

Yes, I did misread it. Having done it both ways, I still don't think it matters if you are careful mounting the plate/pump. The manual also has them installed separately but I've always put the pump on the plate first.

The reason I'm posting is not to argue that the scavenge o-ring cannot be installed in the engine casing first and successfully not pinched/cut by then pushing the oil pump tube into it.  Rather, by installing the o-ring on the pump tube first, there is less risk of a pinch/cut.

Heck, I know guys who can set the flywheel endplay by just pushing and pulling on the sprocket shaft.  Yes, there are skillful hands out there.  However, there are a lot of varying skill levels on HTT.  My attempt is to do some of those folks a favor.
