Hand oil pump

I have been restoring a 1924 bike (sorry not a Norton) with the hand oil pump and drip system.

Has anyone a picture or drawing of one. One that shows the non return setup that stops the oil going back into the tank.

Mine is missing.

Thank you

I suspect you might need a two-way tap - like the one on the attached picture (1902 Minerva-engined Quadrant). At top left the bottom of the pump is visible.

Turn the lever sideways and lift the plunger slowly. The pump fills up. Turn it down and push a slug of oil into the sump. Wait for it to emerge all over your trousers and do it again...

Nothing flashy like a non-return valve.

And here is a 1913 Douglas arrangement. The pump is spring-loaded and goes to a sight glass variable drip feed to the crankcase.

Thanks I have the pump its the innards thats the problem. I imagine a ball sits inside the spring, so as you release the plunger the oil is sucked up, the ball? seats and stops the oil returning into the tank.

Hello Robert, I have a 1924 HUMBER motorcycle with the hand pump oiler you enquire about, and from memory, there is a small 'clack 'valve disc beneath the pump. Google LEWIS MOTORCYCLES and go to Leon's web site, contact him and he may be able to give the required info you want.
