Need To Help Four Stroke Combustion Pump Engine
(OP)
Hi,
I’m making a training tool/website to help people learn about engineering, but I’ve got a bit of a problem. I was working on 3D model of an engine and labelling parts etc. but there is one piece whose function I do not known (see below image).
I’ve asked around but no one I know seems to know what it is. The second below image is a close-up.
This is what I do know:
• Lit is belt driven so it turns (possibly centrifugal filter?).
• The pulley is small so it turns fast.
• There seems to be a connection to the lube oil sump.
• There are jubilee clips so it is easy to remove (which again points to some sort of filter).
So, does anyone know what it is? Item ‘2’ on the below image is for a lube oil filter (probably, informed guess), so why would they have a secondary filter on the suction side of the lube oil system (assuming that it is a filter and it is related to the lube oil system)?
The model can be found at the link below, it is interactive so you can zoom in to get a better look etc.

Any help is welcomed!!!

I think the two bits sticking out the far end might be terminals to connect some heavy duty cables. Also the clips holding it on are not jubilee clips but heavy duty clamps.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Thank you for your responses. There is a lot of conflicting views on this part. The main consensus is for a scavenging dry sump pump, possibly with an alternator attached. Difficult to say though. I might have to try and find a manual! Thanks again for the responses.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
