Sump pan

Would welcome some advice from anyone?s experience here. I picked up this dry sump pan and I am not sure about the baffling? Does the pan need this or has it been added. i.e. is this a normal looking dry sump pan. Also where the scavenge pipe goes it just has a hole at the bottom?

Cheers

Doug

Looks like an original period piece & everything seems to be where it should be as far as I can remember.

Thanks for the replys... Not wishing to get to technical, but does that mean the effect of the rotating crankshaft and oil windage, the oil gets forced or assisted into the small gap that runs lengthways between the baffle and pan?

Yup!

Some people in GB actually call it a windage tray.
Works a bit like a carpenters plane & shaves the oil away from the crank& also keeps the oil that's down there being picked up by the crank. That would create oil foaming & also result in a loss of power.

It is nice to get things for next to nothing, it is also important to evaluate
what you have received is going to do the job for you.

While it wont be difficult to clean the outside and inside of this pan, it is going to be extremely difficult to get the rust and crud removed from the oil channel which is underneath the windage tray. The tray looks to be welded to the pan so removal for cleaning will be difficult, the windage tray should not be welded to the outer pan, take a look at the photo of the oil pan posted under Dry Sump Pan, note the removable oil channel collector cover strip which also has the four oil scrapers formed into one edge.
Dry sump pans need to be thoroughly cleaned during rebuilds & servicing. With a bit more work your tray will make a reasonable dry pan sump.
The single outlet bung is normal, this can be a clamp on arrangement or screw in BSP attachment, depending on how you want to run the pipes/hoses. Quite often a small round shaped wire strainer is also placed inside the scavenge connection to keep unwanted bits of metal from entering the oil pump should something "let go" in the engine. The dry sump scavenge/pressure oil pump is an expensive item and needs lots of care.

Good luck with the clean up.

Thanks for the post and photo's... I did the clean up and got it dipped, it come out really clean. I was conscious of any crud under the pan so I am keeping a close eye on the gauze strainer, and clean it regularly. I have done some good tests including very long straights at max rpm. Just need to see how things go on the track now(?).

Cheers
