Motorbike oil pump turned up last week, and I had a little time to work with it this weekend. Before going to all the hassle of making a proper cover plate- made a temporary cover out of mild steel sheet and epoxied pipe elbows in place for the oil ports. Hoping RTV flexible gasket will provide some sealing, but oil will probably leak oil all over the place. So long as some goes where it’s supposed to ie over the atomising tube, I really don’t mind. Any spillage will go back into a sump, just the same as the overflow from the atomizing tube. After a bit of struggle managed to get the gear removed from the drive shaft, so for initial test runs, motive power will be via an electric drill chucked on the drive shaft.
If that goes well I’ll then have an idea what kind of revs will be needed for the pump, and can calculate some pulley ratios. A final cover plate should really hold the driving motor too. That ratio will be needed to set the approximate distance between pump shaft and motor shaft.
