Find the master pin, burn the center out of each end with a torch, let it cool, and it will drive right out. I have master pins in stock, $25, how much sledgehammer work do you want to do to save $25.

Bolt has strength markings on the head, hex plug will not, plus they look quite different. Bolt likely has a lock washer under it, hex plug will usually have exposed threads showing. It is not likely a hex head plug. Original is standard square pipe plug, not that it couldn't have been replaced. Lavoy

Hadn't thought of the serial number change, good call.

Don't remember for sure, but it is not a bolt, never will be, so don't take any more bolts. It is a 3/4" NPT pipe plug, lower side of the trans facing to the left just ahead of the LH steering clutch housing.
Look in your service manual, should be a pic there.

If it catches when it is flush, the end of the pin is mushroomed. Doesn't matter if you can't see it visually, you are dealing in thousandths of a inch. Grind the circumference of the pin, not the end, will make a huge difference.

LH side of the transmission, basically below your left foot as you sit on the crawler. 3/4" NPT plug.

40 does not have a water pump, possible you have a 420? I will have some rebuilt water pumps in a few weeks. New radiators are available, I don't normally keep them in stock.

Grouser pads are hard on the rest of the undercarriage, drivetrain etc. Best example I have is stomp a shovel in the ground til it is all the way in. Then pull on the handle or try and twist it, same thing as a crawler with grouser when you are trying to turn. Loader just adds another 3000 lbs plus ...

That is a Greenville Steel Car Company/ATECO loader. Noise in the clutch could be bad throwout bearing. As for clutch, not hard to do, done more than I can count, just put an engine back in one yesterday. I have clutch kits on hand. I would advise getting a parts and service manaul prior to tackling...

Not at this time, not in the near future, but I am reasonably sure they will be available again.

All your greasing is overkill. Clean the shaft up, clean up the inside of the clutch tube, antiseize on reassembly and you will be fine.

I run 0W-30 Mobil 1 in several, never an issue.

Starter distance is the same, but it will be lacking some critical mounting holes of the later center section and so will not work.
Lavoy

I have some on hand.
