bridge oiling

I want to oil the bridge on my 56 inch omc cylinders. Can somebody help.

I think there is a service bulletin showing where to drill the holes, anyone got a copy?

I recall Bill Gohr mentioned that. Anybody know about it

i scribe each piston then center it up and drill it, chanfuer the holes..... i scribe them with it all bolted up torqued to spec, even if i'm just puttin it together just to get that scribe mark.........

Size hole??

Yup!,1.5 to 2 mm will do it as it is under pressure . Be sure to champher the holes as this helps as well.

if the bridge is still full size, 1/8 or 7/64, three, three holes per piston...

Any pics. of that Fred? I would like to understand this better, thanks.
