Fixing before it breaks is usually a lot cheaper than after. Depends on how many other parts it takes with it when it breaks.

One other thing. Fixing it it the shop is much easier than in the field. It usually breaks at the worst possible time and place.

I have a couple of 420's. You can't just raise the seat. At least that's what I've found. You need both up and back to keep the "working angle" towards the pedals.

It's pretty obvious that these machines were made for a smaller generation! At 6', long legs, big feet, I'm a bit cramped. It's more obvious if the operation requires a lot of movement, like loader or dozer as opposed to farming operations like plowing or discing. I raised the seat and moved it back...

If you flush it per the manual it's gone (water). Put in an additive it absorbs\changes it but it's still there. That's assuming there's enough additive to overcome the problem.

Got a chuckle out of your last line......

"Ease the shaft out...."

Given the project so far, I'm surprised to hear the word "ease"

The plug in your photo, what case is it in? Drain transmission\differential together? Must drain something!

I've only removed them when they were on the top of the sprocket. Front idler backed off, no binder. I used a loose fit pin to finish driving the master out.

I did use a binder when reinstalling it.

I know it's a removal. The center wear point has gone beyond the track hole on the inside (it was still in line at first). The wear point is now catching the inside of the track on the opposite side. The pin has possibly dropped down slightly into the wear areas and caught. Possible it's catching on...

If the outside is flush, it probably is the second side catching the wear ridge. You should be able to feel the wear area.

Can you tap it back out a little and get a strip of emery cloth around it to clean it up?

I bought a loader with cleats. Got it cheap too.

Why? Broken transmission case. Enough said...

Just stopped to think about that. First crawler I bought also had a loader and cleats...... And a broken transmission case......

A pressure wash, Dupont rebuild and he might get a bite. In spite of the money spent it looks like....

When it's running, the oil level is lower. It's not over filled is it? Level above the pan gasket?

I once watched 2 guys turn the pins on my Dad's D2 Cat! Sledge hammer and a long handled pin punch. 2 day job!

Can you get enough space to remove the clutch bolts? Rotate the engine to get to the next set?

Maybe through the starter opening with a long extension?

Driveshaft rusted into the rusted clutch?
