Starter issues

replaced starter and still have to replace contacts and brushes yearly what is the problem

 

Did you replace with an OEM starter, a rebuild or...? What kind of environment do you live in? Humid, with salty roads?

 

Replaced with new one I guess I need to get an original Nippon

 

Hard to beat the Nippon Denso starters for these trucks.

I would think that many rebuilds would use the Denso shell and works (there's so many of them out there on Japanese based vehicles, for the last however many years) principally because the most common failure point is the easily replaced contacts/plunger. But I've never bought one. I just fix the Densos I have.

 

they have to be replaced due to what? wear or ?
the starter is the second to the last end of the line electricaly speaking, the grounding of the starter is the end... anyway, it is a system and if the grounding of the motor is not very good all of the current that is flowing through the brushes has to go somewhere. Is the commutator clean and smooth? if not you are running the brushes over sandpaper everytime you use the starter. A voltage drop check on the starting system would be a good place thing to do also.

 

I bought a rebuilt from Toyota price was not bad I could live with eating the core charge

Giving me one to rebuild when time allows
