Hi Guys
Muskrat: Don't know about the scroll - a toolmaker in the BSA Owners Club assembled that part of the motor, and he is on holiday so I cannot find out
A10Boy: I have used a normal gasket with loctite 5910, and then just Loctite 5910 - no change - assembled three times with same result - oil leakage
Certainly there is no mention in the Haynes manual of a cork seal, but in the BSA Draganfly catalogue it mentions the cork seal 67-708 as an Idler Pinion Oil seal.
I used grease in the dynamo drive sprocket compartment, and had agrease / oil combination dripping out
I, like yourselves cannot see where it is coming from, as there appears to be sealant on the oil pump/ dynamo drive sprocket interface
I am wondering that, as there are signs of the chain having fouled or jamed the lower side of the compartment, whether this has bent the lower end of the compartment down, so oil from the oil pump area can access the compartment
Is the oil pump area full of oil for the pump to pump, or is this just residual seeping out of the pump?
The pump has brand new parts ex SRM
