Outer timing cover equivalences

Post by madsundaysurvivor »

I need a outer timing cover for a b44vs 1969, Do I only have to take in mind the diameter of the hole for kickstart?
All models (b25, b44, bb50) and years hace the same outer cover?

No, you also need to check the slot position for the points wires, the type of hole for the crank end seal as the B25 version has a circlip which moves the seal out further which risks it not fitting a B44 crank. There were other detail changes as every year there were changes.

Outer timing cover should not be affected by the crank seal, to my knowledge. The later outer timing covers move the wiring for the points to a slot or a hole at the points cavity so the wires do not have to be trapped inside which is a lot handier when removing the timing cover.

Everything being factory then it should still work, but if in the past the end of the B44 crank has been hammered to a balloon and then shortened to bring back to size then it could miss the B25 seal.

kommando: I think you're right, but that applies to the inner cover, not the outer.

Thank you for your answers. I knew about the difference between the seal of b44 and b25.
about the outer timing cover, I don't use points on the hpi ignition (is like the electrex) so the position of the cable hole is not a problem.
So, Could I fit a b50 cover in my b44?

What about the kicker shaft hole diameter? Is that the same?

yes, what about it? that's my main doubt.
I don't have the kickstart quadrant either, I could buy a b50 if the gearbox side is the same

I know the early ones had a smaller diameter, don't know about the B44, but later B25 and B50 had large diameter....just need someone who knows for sure.

The early B25, B40 and I think the early round head B44 had the smaller kick starter shaft.
