Kohler Starter ? K301

[oe espo 32]

So tried firing up my 312A after sitting all winter.  Dang mice behind battery!  Wouldn't crank over very fast.  Fired up the 314 no problem.  Battery was older in 312 so I just swapped batteries still wouldn't crank fast.  Dropped to 10v under load.  Pulled starter and cleaned it.  brushes don't look bad but it was howling.  the bushings were in fact pretty sticky.  looks like bronze or oilite bushings.

Do I put a drop of some sort of lube on these bushings when re assembling??

Also bendix sticking really bad  i red here that it should have kohler lube but i want to stick back together and try it.  so maybe some lithium?

What else could cause slow crank?  Thanks.  

Should I clean up the stator and file the brushes or not

Clean the bendix drive and shaft and lube it with a dry graphite.

With any electrical problem you need to start by cleaning and tightening all electrical connections including the grounds. Also, charge the battery and take it to an auto parts store and have it load tested.

a drop or two of motor oil would be good.

File the brushes down to clean up?  Stator?

I'll add a drop of oil to the bronze bushing it was sticky before I cleaned it.

I would file/sand the brushes before reinstalling them. Also check the bushings for wear. If they're sloppy,  that will cause a slow starter. Replace if necessary while you have it apart.

Well armature is toast.  After several teardowns wouldnt spin over.  Took to starter shop.
