To my untrained eye the starter looks pretty good. I did find a 2" piece of pinion sleeve spring 2 (#53) broken off. I wonder if that is the source of my problems. Maybe something to do with the spring not always winding enough to engage the pinion. Though, I would think that it would happen all of the time. Any idea if it is replaceable?
Part # 23443-43600.

I edited one of my posts, just before the description of your procedure to dismantle, including the exploded view of the 1971 Part Manual, so people can refer more easily to the part numbers you mention. This is the first time that I pay attention to the ISO Starter. Out of curiosity I've compared the parts numbers. Incredible that Nissan went though so much trouble just to change the bolts and screws. And because of where the screw goes, the solenoid also changes, and the gear case. All the internals are the same. Go figure. And all of this for only a couple of years!!mtnPatrol wrote:...

You might be able to source this spring in other places. If it's similar, will probably do the trick. Difficult to say for good if that was a source of your problems, but probably you're right.

As I looked closer, I noticed a good sized recess that extends approximately 25% of the way around the bushing. It is fairly wide as well. The recess is near the far end of the bearing. In it sits something like felt. That material was only in about half of the recess. Is that recess and material supposed to be there?

The only thing I have to show for all that work is a hole in my thumb where my scribe slipped and stabbed me
Since mine grinds more than occasionally I'm going to get a new starter. Will this one do the trick: http://www.amazon.com/DB-Electrical-SHI ... B00AWMRLGM?
