[QUOTE="Marcus Bowden, post: 117215, member: 3287"] Plus a Honda oil pump supplying into the gallery and cylinder lubricators blanked off, cams and followers have done over 300k so I know it works, it's just big ends I have to keep replacing. Plane bearing floating bush is what I've just put into an "A" comet with the supply pump increased to 3/16" wide delivering half as much again. On post-war Comet's, I'm thinking of increasing the size of the Honda pump and directing it all into the filter housing so it gives a constant supply with mechanical seal to the main shaft possibly restricted as I like to see at least 8 to 10 psi to cams, normally running at about 1 Bar. As for modifying a twin to plain bearings is yet to be thought about. Never have I replaced a ships B/E bearing and they do hundred's of thousands of "hours" lasting 25 to 30 years that I've sailed on! Roller B/E's take little oil but the contact surface is bearly measurable. [/QUOTE]
