Re: flathead fuel pump push rod
Maybe the large hole in the rear bearing is not lined up with the bushing above it. I found this out as I disassembled mine for rebuild.
The previous owner did a rebuild and when he couldn't put the rod down, he must have just knocked it down and it bent the edge of the bearing into the gap between the two rear journals. It worked but I had a hard time pulling the cam out for my rebuild. You may be able to look down thru the bushing and see the problem? Terry Last edited by Overkill-F1; 02-29-2020 at 07:03 PM. |

Re: flathead fuel pump push rod
All you will be able to do is tap the bearing further inwards with another bearing as a punch, not rotate it or pull it out.

There is always an electric fuel pump.

I would place something solid over the old bearing to spread the force of the tapping. If it was mine I would try this before removing the cam, lifters, etc. because you would still have to pull trans, flywheel and rear cover. Terry |

Re: flathead fuel pump push rod
We may be getting the cart before the horse here. Need to determine what the problem actual is first. It is most likely the cam bearing being in the wrong position, but that needs to be verified.

Re: flathead fuel pump push rod
Does the rod go in but is a tight fit?

Re: flathead fuel pump push rod
I know I posted earlier but this seems like the type of problem that will only get worse if you try to enlarge or move the cam bearing without disassembly.
