Need a tiny oil pump.

[Pete.]

Ok folks this will get you thiking.

I need an oil-pump out of a small 4-stroke. Something like a 50cc or 125 possibly.

It must be physically as small (thin mainly) as possible. It must have a fully-separate housing from the engine casing, in other words if it's removed from the bike it must still work as a pump, but I don't mind making a backplate for it. It should ideally also normally run at crank speed or higher.

Any ideas?

Seen them used as chain lube system

Hmm good lateral thinking, but this must be an engine-oil pump.

What you lubing?

Would a 2-smoke autolube pump not do it? or would it not have a high enough throughput? Early suzuki ones run at the same rev speed as the rev counter cable.

I've seen a scotoiler used to lube the bearings in the supercharger on a top-fuel drag bike.

These are very good if you can work out how to fit it in your application:

I like the look of that Morgo unit, seems perfect but there's no indication on price or dimensions at first glance. It also quotes scavenge in the text which is what I want it for - to scavenge oil from my turbo.

Keith my mate has a couple of old triumph pumps but I didn't want something that I migh have trouble replacing/servicing.

There is a very nice bespoke pump I could egt from the states that is 100% specific to my bike model ad the application for around a couple of hundred quid plus shipping. I just had the idea I might be able to manufacture something, since I've made everything else so far.
