Can anyone provide instructions on disassembling a Nippon Denso starter for my L210? Inherited tractor from my deceased uncle and wanting to get it running again. Grew up as a kid with my cousins playing around with it. (yeah I shouldn't have, but we made it out alive!) :)

Why do you think the starter needs rebuilt? Are you equipped with the required tools for a rebuild? Do you have a source for parts? We have a local shop that rebuilds starters. I took my Mitsubishi starter in - bad Bendix spring. I couldn't get the part. He could get a complete Bendix for about $75 but a complete brand new starter was under $200. I opted for new. If you have no local starter rebuild shop I can provide information for mine in Eastern Washington.

I provided an answer on your previous post, it's literally 4 or six small bolts and it comes apart, not a lot to it.

Now the issue is have you ever rebuilt a starter?
Most haven't and it's best to leave it up to professionals.

Have yours rebuilt locally or just buy one new.
Save the old starter even if you buy a new one!

Nearly anyone can bolt on a new starter... and most mechanics who wish to make money do just this. (They get paid to bolt it on and also get their 'cut' on the starter cost)

I have fixed many 'bad' starters. (I do not 'rebuild'...no repainting.)

The starters I have fixed were from Snowmobile, lawnmower, car, truck, JohnDeere bulldozer... and even my Kubota tractor.

In most cases, it is as simple as disassemble. clean, lubricate and resemble.

Sometimes I have to fabricate a replacement part, make a spring, add some silver-solder to contact-points, resolder a wire....etc

One was simply a lack of lubrication.... it would spin fine with no load... but as soon as it had the load on it... the bushings would have so much friction that the starter would stop spinning. A good cleaning and lube of the bushings fixed that issue.

In many cases, I use dremel-tool with fiberglass brush to clean the area where the brushes make contact. (commutator)

I have NEVER encountered a starter which could not be fixed.

In some rare cases, the gear on the starter may need to be replaced if the teeth are worn down.

Whats your starter doing / not doing. Is it clicking, grinding, not spinning?

Clicking, Check solenoid: Put starter in a vice hook up a (12V battery) ground to the nose cone flange. connect the Positive to the terminal on the solenoid with the cable running to the motor. If it spins, probably a bad solenoid. To confirm, you can hook the positive to the battery side of the solenoid & 12v to the trigger stud on the solenoid, no spin or click, bad solenoid. (weak batteries kill solenoids)

Grinding: worn bushings / bearings will let the armature slop around and hit the Pole shoes.

Not spinning / getting real hot: leads could be shorting out or worn brushes

Tear into it, take pictures as you go (for reassembly) and see whats going on. It may just need a good cleaning, dress the armature & brushes with emery cloth, grease the bushings and clean all contact points (It gets it's ground from its mating surface) Good luck.

Oh yeah, if you have a "Good" number on the starter you can get all the consumable parts.
