D950 starter. Need one.

[fastline]

Per my other posts, I just got a D950 patched up and running. However, it is obvious to me that it cranks over slower than normal. Even when jumping off a running vehicle and confirming that I am getting 11.3V during cranking at the starter (which is roughly normal), it just does not crank worth a damn. I inspected the brushes and commutator is is good shape. Certainly not the issue. I meter tested all bars, but didn't test the rotor as i didn't have all my tools.

Starter pulls 150A. I'd like to figure out if there are other starters for these? Only one variant? Need to see if there are any options out there. This is a direct drive starter and I REALLY want a gear reduction or 'high torque' starter on it. Sort of ridiculous how much this tiny diesel struggles.

I know this is not a fuel timing or binding issue.

What did you do to the motor?
Sounds like it's way to tight since your pulling 150 amps.
And no there is no gear reduction starter available for the engine that I know of.

The engine struggled like this before I did anything to it. Only thing that was done was hone and rings basically. I am not convinced the starter is not hosed. A friend had this thing before and likely cranked on that starter for an hour at a time. What I suspect is shorted windings that I cannot detect without other equipment. I REALLY hate throwing parts on a whim but the engine is certainly free.

I do agree, it should not be struggling like this.

Oh now if someone over cranked on it, and overheated it, you more than likely need a starter.
