Oil Pump Screen

[Aiken Racing]

I have a 5-port pump on my Kent and I need to get a rebuild kit for the pump. It got pretty chewed up due to loosing a bearing so I'm replacing the whole inside. I mic'd the ID of the whole pump and it's within spec. Both the rotors

I read in a couple posts about a oil pump screen.... I don't have any screen in my pump and if I should where does it go and where can I get one?

Thanks,
Chris

Chris: Absolutely, you should have a sump pick-up screen! There are lots of little chunks (casting flash, timing chain roller shell pieces, valve seal springs, etc.) that can get loose and chew up the pump; if substantial enough, a piece can jam the pump and take out the whole engine.
The common FF dry sump pan has a trough running down the center, with the suction pick-up fitting on the right side. Across the trough, opposite the pick-up fitting, is a plug; the plug should have a brass screen soldered to its end, so that the end of the screen seals around the pick-up fitting.
IIRC, Dave Bean has the pieces. On the pan I use, the pick-up fitting is "male cone shaped" so that the screen centers on the fitting as the plug is screwed in. Once together, I don't remove the plug until the pan is off and can be cleaned. You'll be amazed at the junk that can collect in there.

Yes you want to run a screen on the oil pan pick up. If you do not have the type of pan that uses a plug/screen that screws in from the opposite side of the pick up tube, you can have the fitting that screws into the bottom of the oil pan drilled out and a stainless screen epoxied in to place. We sell those screens if you can not find one. Would not run an engine without a pick up screen. Neil

Well I was told that I have the DB-1 oil pan on my Citation.

I don't see where a screen would mount onto my pickup.

Is there any screen I can use that is not something that I have to buy at a race shop?

I'm not sure I understand what you are talking about drilling out fitting in the bottom of the pan.

You can see the bottom of my pan here:

That looks like an ARE pan not a DB1 and would probably require one of the screens that Porter sells which is shaped like a tube with a closed end . You drill the end of the pan fitting so that the screen slips into the end of it and epoxy into place.

Yeah, that looks nothing like the pan on my DB-1. My oil pan has a screen at the bottom of the oil pan. It's a fairly coarse screen shaped like a witch hat that surrounds the hole on the INSIDE of the pan, around the oil pump inlet.
