Rear chain lubrication screw

[stevewhitt]

Hi Guys

There is a hole in my primary chain cover which needs, I believe, a chain lubrication screw!

The part book lists 5770-43, which I think is correct - please let me know if I am wrong.

I get the feeling there should be a screw in addition to the needle?

I can't seem to find anyone who sells one. Drags doesn't even list it, neither do ACMEStainl.

Any ideas very welcome.

The screw has a needle point on the end and a knurled cheese head - there's one here:

Thank you very much Simon, for some reason, not in my parts list.

hi some clutch chain cases just have a screw on the outer case and some have a longer tapered screw and spring to lube the rear chain i think the longer ones are on the open rear chain guard the fully enclosed chain guard has a rubber pipe from the oil tank to lube the chain on my Ariels with the long screw i turn it in to turn the oil off and stop the oil getting on the rear tyre and i lube the chain with a spray on lube and once a year i take the chain off a wash it and if it is ok i put it in grease you get in tins and heat it up

The type you are looking for was only fitted to the few contracts with steel chain cases instead of the usual ally ones. They used I different arrangement with a plunger, Screw and spring. I have never seen one but I may have a pattern that I can draw for you.

Hi Roger
Can I take you up on your offer of a drawing for part number 5770-43 please?

I have one of the few metal chain cases and need the adjuster.

Thanks

Sorry I don't have a sample to draw.

Thank you for looking Roger. I will try the larger audience on here and FB.

Evening all,

Does anyone have a drawing or can provide me with a sketch of what the oil adjustment screw looks like (its not the same as for the aluminium chain case). Its part number is 5770-43.

Thanks in advance
