JDcrawlers Messageboard

I suggest replacing the switch if needed and repair the wiring, then keep a spare key "in a discrete location" at the farm. Find a good hiding spot on the crawler and put the key there when leaving, not taking the key home, many do this.

Welcome to the Boards. I am going to say it will not fit without modifications to the mounting pin ears. There are no same part numbers used for the buckets of the two machines, that I found. You say it is local, best to go measure it up yourself to be sure. Measure the ears where it pins to the boo...

I can't see any pro to doing such. You will need a way to turn excitation to your alternator on and off (depending on the alternator you have) as well as control power to any electric gauges, except an ammeter which can stay live, you might have. A battery master switch located in a discrete locatio...

Below is a link to the 6300 Bulldozer parts catalog. Try using the part numbers you are looking for in your search, if you haven't.

I agree with Bruce. find a loader crawler and keep this one for parts. To me it does not have a great value as it sets. The biggest plus would be if that 15,000 they spent on repairs included a complete new undercarriage, a few hours before it got damaged and parked.

You posted sugar was put in the gas tank. Does it have a gas engine? A 450B should have a 4-cylinder 219 CID diesel engine. If it is diesel the 4219 engine was used in a lot of JDs, not just crawlers around that time frame. Some air compressors and generators also used the 4219. You should be able t...

Welcome to the Boards. You posted the PTO control handle is moving and it feels like it is moving something inside. Confirm the handle is moving the shaft going into the transmission. Also, that the PTO shaft is not rotating (confirm it is the shaft out of the tractor that is not turning, not just t...

The 450G adjusters used a check valve with a zerk in one hole, instead of the zerk and set screw ball set up having two holes, side by side. Some of the 450G adjusters also had hinged covers over the zerk check valve. The zerk/check valve would be between ears that had holes for the cover hinge pin....

Duplicate post deleted.

Welcome to the Boards. The ball should go in under the square head set screw located beside the zerk where grease is pump in to extend the adjuster, IF that is the one you have. looking at the parts catalog it appears two different ones were used. One uses the ball and set screw the other uses a che...

I was just looking at the drawing in the online parts catalog and guessing size relationship.

I bet at least part of the reason was JD figured out they were giving away money having the specs online so people could substitute things.

A few years ago, JD online parts catalogs had info on some parts like hardware, shims, some seals and O-rings. They did an upgrade, and that type of info was taken away from the general public catalogs. I think a dealer might have access to some info as the parts guys at the dealer I use have been a...

Welcome to the Boards. I suggest you give Lavoy a call. He provides this site for our use. his business sells and repairs crawlers like your 440IC, if fact I think he has one in his shop now from things on his Facebook page. His phone number is 701-361-1006 during Central time zone business hours. H...

They appear to be for alignment of the moving parts so I would think stacks of washers would work, might take a bit of fiddling to get it where you want it.

A search using the part number on the JD parts site shows that is the only place that dowel pin was used. Finding a salvage yard with a transmission parted out is likely about your best chance. Send Lavoy an email or give him a call he might have a suggestion of someone to check with. What is your g...
