Dear Steel Soldier Community,
Starter motor loosens recurrently
The problem occurred after about 1 tank of gas.
The engine would not start because the starter drive gear was slipping on the flywheel, it was not engaging properly.
Analysis:
Both fixing screws were loose and the starter could be moved by hand with a play of 5 mm.
Action taken:
Screws tightened with ratchet, was enough for 2 starts.
Further measures:
Disassembled both screws one after the other, cleaned them completely and also cleaned threads in the engine block. Tightened with 30 Newtonmeter and secured with Lock Tide.
After another 4 starts, same problem.
Screws again cleaned and tightened with 40 Newtonmeter.
Interesting, front screw (screw towards cooler) loosens while tightening the rear. Distance to flywheel not checked.
2 starts, starter again completely loose.
OK, I found this video that explains the distance and how to check it, as well as the logical procedure with the shim washer.
What is the fault if the starter is tight for 1 to 2 starts, the starter pinion engages the flywheel cleanly and then comes loose? Now it sounds like the starter pinion is not engaging cleanly and spinning on the flywheel.
For general information, my M1009 did not have the rear support on the starter motor installed.
After a little research I now know it is the 28MT DELCO REDUCTION starter motor. ( Link to the corresponding YouTube video LINK )
What is the most expedient thing to do?
Please do not get me wrong. It's really frustrating to be afraid that the starter drive wheel will slip again on the flywheel every time you start the engine.
Please describe troubleshooting step by step and in plain English so I can minimize translation misunderstandings (errors).
Best regards

I used a 1/8 inch Allen wrench. The measurement you want is .125 inch and that is same as 1/8 inch. A 1/8inch round drill bit would work also.
Now the question to the community:⅛-Zoll bzw 0.125 Zoll (= 3.2mm)
