Question about Denzo direct drive starter variations
 

I have breakfast with groups of old car guys. This morning a old guy
that runs a starter/ alternator repair shop, says that a man brought
in a denzo direct drive starter that was on a small ford tractor with
probably a 3 cyl kubota diesel engine. It had exploded from not
disengaging when the engine started. This is basically the same as a
starter in a 89 nissan B210 except for a different starter drive and
more interestingly the nissan starter uses 4 brushes and the diesel
starter uses only 3, 2 + brushes and 1 - brush. The diesel armature
uses .003 smaller wire. His whole sale cost for the diesel starter is
5 times more than the car starter. He told the customer, if you want
to take a chance, I will put diesel starter drive on the cheaper car
starter and save you a lot of money, if it doesn't perform
satisfactorily, return it and get your money back.
My question is about the different electrical flow patterns and
torque values in the 2 armatures. And i would think that the diesel
would want more torque and need more electricity and not want fewer
brushes to conduct that electricity.
PS I hope the guy isn't mistaken and the the diesel model really
did have 4 brushes and one of them disappeared in the over speed.
Thanks for listening

I'll bet the Nissan starter works just fine there. The larger wire
should compensate. You didn't mention relative brush size between the
two. I'd give it a try if it were my tractor.

There was a "Canadian" 210 starter that was geared down; that
would be even better...
