Interesting, I can see rust in part of that crack which means it has been broken for a long time on the inside of the crack. That is something that happened before it was put in the vehicle probably. The discs are the same for the most part, The new one will have that metal in it, you just will not see until is starts to wear a bit. The metal part and spring covers are just a manufacturer change. I would just have that Z-bar welded up and you will be good to go. If you get a new one be sure it is the same because there are two different styles and they require different rods.

I knew what this was going to be when he ruled out the other stuff. I had the misfortune to have to drive a Stuart tank backward off a prime mover (designed for the Abrams) under the same circumstances, at 3AM, after having gone without sleep for about 40 hours.

Once you're going, you're going....until you shut the engine off, or until you die.

Not to mention those trailers have these really short ramps...just enough to help get the nose of the Abrams up there. With a short little tank like the Stuart, one moment everything is on the level and then once you're past the balance, WHAM!....you're looking at the night sky. Jeez, I thought I was gonna have a heart attack!

Had I been better rested I would have had the presence of mind to say, "You want me to do WHAT?!"

Well, anyway...congratulations. Once you get this puppy back together you'll have lots less to worry about.

Cheers,
TJ

Got all the parts for my repair yesterday. It seems to me, that there was an earlier repair on my M151 done by a former owner. They did not use the gaskets. So I have now new gaskets between engine and clutch housing, clutch housing and gear box. Some screws and bolts were not re-installed at the bottom of the clutch housing's pan. Now they are. Power pack is back in the body and everything on the passenger side is mounted again.

Tomorrow we will work on the driver side.

Two questions:

In which TM can I find anything about the correct play for the clutch and clutch pedal? How do I adjust it correctly? From my point of view, I can only adjust the pole coming out of the clutch housing.

In which TM can I find any information about the starter motor? I have the feeling that it is not well adjusted and would like to check the measurements. At the moment it looks like the pinion is always on or in touch with the flywheel.

The clutch adjustment is exactly as you said, take the spring off and screw it in to raise the pedal and out to lower the pedal. The manual says 2" of pedal free play if I remember correctly. I recommend setting it with what you are comfortable with. As long as it fully engages when the pedal is up then it is good. The starter is fine and there are no adjustments. Someone turned the drive while it was out of the vehicle. (wonder who that was Richard? :roll: :twisted: ) It takes the engine spinning at higher rpm than the starter to wind it back in. Put it in the way it is and the first time you start the engine it will go back to normal.

Hello Rick,
Hello George,

Thank you very much. The clutch pedal has been adjusted, everything is fine now. I also received some pages from Ken from the TM with the measurements in Millimeter. :D

Rick, you're right with the starter. We started the engine, stopped it and pulled the starter to double check. Everything was in the correct position now. As you said. But is wasn't me who turned it outside the vehicle. :wink:
