Distributor shaft end play

cstory · Apr 22, 2017

How much end play should distributor in MF 135 with
continental engine have? All Help Appreciated...

Not critical, cap or rotor has a spring plunger or arm that pushes down when running..

It should have very little, if any, end play. A little is ok but if its excessive it will cause the shaft to bounce at idle.

Since it's a Delco-Remy (General Motors) GM distributor they say .024" - .047". I would rather it be close to .024", to me .047" is too much.

The Z series Continental had a thrust plate on the cam that can wear and cause axial movement of the cam shaft that can drive the distributor up. Are you breaking rotors?

Not breaking rotors, just able to lift up an rotor shaft and it move up 1/4" or more...

Exactly, what I am experiencing with 135 at idle, not smooth
but throttle up or put under a load pulling disc plow tractor
runs much better.

A 1/4" ? It's toast. It'll need a new shaft and bushings. Or just get a reman unit and be done.

The shaft for the rotor is held down to the lower driveshaft in the distributor by the advance weight springs. When you lift up on the rotor shaft does it feel like something is pulling it back (like a spring). Sounds like you may have a problem with the advance weight mechanism underneath the plate the points attach to.
