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 |

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.

There was a "Canadian" 210 starter that was geared down; that would be even better... -- A host is a host from coast to & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433 |
