Installed a new 39 Mt starter today ... no start yet

YMMV, but I haven't had much luck with that starter on an N14

First one kicked out the starter gear while my driver was idling in the cold a few hours after install and chewed up the flywheel pretty good.

2 weeks later replacement died while in a dock. Went back to the old heavy style and no more problems.

 

I put a 39mt on my cat about 4 years ago. I did have to replace the top magnetic relay once, but otherwise has been trouble free.

 

Biggest killer of starters is weak batteries. A starter will always draw X amount of watts. If battery voltage is low, the starter will suck more amps to compensate. Amps = heat. Heat = dead starter.

 

I replaced several MT starters on my 3406E Cat... Finally bought a started with gear reduction.. I like it much better. Not sure if those are available for N14 engine..

 

That's what the 39mt is, a gear reduction starter.

 

I swapped out my old 42mt for a 39mt about this same time last year and it's been a good starter so far.

 

I've got 4 of theses 39mt starters out on the road and oldest one is 8 years old.. no problems at all. At half the weight of a 42mt there sure nice to install too.!
