Hi

I'm putting the finishing touches on my rebuilt '54 261 engine. I have put #1 cylinder at TDC by watching the valves and lining up the "BB" on the flywheel with the pointer in the bellhousing.

Then, I attempt to drop the distributor in the hole and align the tang on the distributor with the oil pump drive slot.

Now the problem begins... As soon as the cam gear and distributor gear start to engage, it becomes difficult, if not almost impossible to push the distributor any further into the hole! :mad: :mad: I've even lightly tapped the housing with a hammer to get it to seat, but that just makes it all the more difficult to pull out! :mad: :mad:

When I disassembled this engine, I don't remember this being so tight. In fact, I pulled it out with one hand quite easily.

Does the fact that this is a rebuilt engine with very tight clearances make this much difference?

Yes, I did check the obvious and the cogs on the gears do in fact "mesh" in coordination with each other.

As always, any input is greatly appreciated.
Steve
