JDcrawlers Messageboard

If your looking to know how thick the ice needs to be, give the king of obsolete an email. Has an amazing collection of different restored crawlers in northern Manitoba. Runs the ice up there all the time. Although he doesn't have any jd crawlers he has about a dozen internationals and cats. I'm sur...

I have a 420 with 4 bolt pads and a 40 with 2 bolt pads. I even have some pads that look to be 6 bolts or a generic pad, might be that someone used 4 bolt pads and drilled them to fit the 2 bolt. Are the 4 bolt pads for 420 and later or is there 420's with 2 bolt pads? Just curious in my quest to fi...

If it is a free floating part like a broken bolt flange, then you can weld it pretty easily, but if it is locked say cracked along a piece this is were you get into a lot of trouble. I've had some casings welded and it took the welder a lot of time to do it, but for a broken ear wasn't that bad, an ...

I have a 420 and a basket case 40, the 420 tracks have 4 bolts the 40 has 2 bolts. I have a 4 roller - is it possible for any of the final drive, steels or through out assembly to be the same to a 420.

My 57, moved it with pinch bars, wow was that a lot of work, pulled it off the trailer with a come along. Than pinched each track back and forth into the yard. Not recommended but possible.

Has anyone been able to make a controller? I can see the idea but has anyone build one? Was it real common to just through them away when they stopped working, seems to be alot of guys with out one, including myself.

Dave

What is the price estimate on a set?

Dave

Some more pics of the hydraulics after i put new rams and hoses on. Had to cut the old rams and there mounts off to get these ones to work. Now it barely creeps and i'm not dumping oil from the rams. If i get a chance later i will rebuild the valves. Got a pic of the holt plate on the blade as well....

Is it possible to get the flat track pads? I have the field pads now but would like to switch to the flat ones. I guess if the price is unreal then i might look at making a set.

Dave

Any possibility of some pics of the rebuild?

I might go after mine this winter.

Dave

If you look at the center of the blade you can see the holt weld plate on top of the blade. I have since rerun new rams and hoses. Cleaned them up a little bit as i continue to work on the crawler. I re aligned the blade mounts and put new bolts in as some were rusted and a couple were broken. I'll ...

This is the 1958 420c that i got from Fogswamp here on the board.



Dave

The 420 i got in Washington from Fogswamp had the same blade, mine says holt on the front, might be different on yours but i swear the blade is the same. I have the gearmatic winch on mine, carco is owned by the same company that owns gearmatic now. I used a 7000lb trailer to haul the crawler from T...

Worst part of up here is the price of gas jumped about 5 years ago and killed all the foundries the only ones left are doing aluminum. All the steel work i know of is out of china. I'll have to work on it in the winter, tried to get some parts off it and they are rusted solid, probly how they broke ...

Sent paccar an email and they haven't got back to me, seems alot of people are looking for the manual for the 8a, google had pages of guys trying to find them in one forum or another. I need to pull the winch apart and see whats missing, i'm working on casting a new cover, be aluminum but hopefully ...
