Hello Everyone,
I've noticed recently that occassionally when attempting to start the 70 when the starter button it would spin up but not crank over the engine. The next time the starter was engaged it would crank normally. Well... This week the starter would spin but the engine would not crank over at all. The ring gear on the flywheel looks decent all the way around, I rolled it over by hand to check the whole gear and all the teeth are there...
I didn't think to take a picture of the pinion engagement but it looked pretty good. The pinion gear turned freely without dragging on the over-running clutch so I expected a failed clutch.
The starter appears to have been gone through recently but I don't really know much about the history on this tractor.
So I ordered up a new drive, pulled the starter to find the pinion gear appears to have broken away from the inner clutch sleeve, it freely rotates and slides up and down about 1/8" inside the drive.
The starter is a Delco #1108981 and according to the parts book uses a #1924589 drive assembly. This is a 1954 Year #15523
I ordered one locally (using the Delco #) and so far it looks compatible.
My concern is putting in the new drive to have the same failure occur. Anyone else have a similar starter drive failure?
The new drive looks beefy enough but only has 3 spline teeth inside vs 6 on the old unit, should I even be worried about this?
Is there a source for a heavier duty drive that someone can point me to? this one ran $28 and online I found one that was over $60. (Standard Motor SDN233)
Here are the pics I took after disassembly. Thought/opinions anyone?
Thanks! Carl
