Cylinder base issue

#1

Post by PanScott » Sat Nov 09, 2019 11:43 pm

Last January, I blew a front cyl base gasket. It was blown completely out at the oil feed area. It is a 56FL That has 63 outside oiler heads on it. The heads are fed through the can cover like a Knuck and had been together and running for years. When I took it apart it had 48-62 cylinder base gaskets which has the oil feed hole in it. It had shit chrome washers on the cyl base studs which I think smashed out and loosened up causing the base gasket to blow. I replaced the gaskets with 63-84 base gaskets to plug the oil feed hole, and bought proper heat treated washers. I fired it up today and damn it, it is leaking at the cylinder base stud. I gotta tear it down and am wondering, should I plug the feed hole in the case?

There is no reason not to plug both oil holes, remember that there is also one for the rear cylinder too. I would suggest a small Allen head set screw, just be sure to flush out the chips before installing the screw and try not to screw them in too deep so as not to block the oil going to the lifters.....

BTW: The head bolts use thick 7/16 flat washers. The cylinder base studs call for 7/16 split lock washers, H-D # 7056. Those should not loosed.....

Exactly, the cyl bases had chrome flatwashers on it., I put Colony lock washers on it.
