Hyster H30F-H60F:
Distributor breakage

I am continually replacing the drive gear roll pin. I upsized the pin and loctited the gear to the shaft, which lasts longer but then the timing weights flew off and destroyed the unit. I have replace the entire distributor x2, with cycle repeating itself. When I hold the distibutor I can feel vibration through it, what could it be?
My distributors are electronic so there are no distr. cam lobes. Help is needed. If this is the wrong forum please direct me. /Glenn

Turn out to be the governor, was missing 8 out of 10 ****. When the only 2 dropped into the pan the cam was allowed to float horizontally which changed to mesh of the cam gear and the distributor gear. Engine is now undergoing a total rebuild.

Thanks, I will start with the pump. Just what I want to do, climb under a grungy old forklift but better that removing the counterweight etc to remove the cam.

Well, I'd probably start by checking the oil-pump out. Broken teeth, excessive wear or debris can shear that pin easily.
A screwed pump would also give you the vibrations.
Short of that, pull the camshaft and check the gears and the bearings.
I honestly can't think of how worn cam bearings would break the pins, but if it's not the oil pump then we're just going to have to eliminate everything else.
A worn cam bearing or damaged distributor gear could give you your vibrations though...

The forklift is a Hyster H30F with a G193 Continental L4 engine. I do not have any serial #s at this time.

We'll need some more info.
What is the model & s/n of the unit, and what engine is it?

From what you've allready been through, you'd better check the cam and the timing chain/belt and tensioner.

But we will need more info to give you a better idea of what to look for.
