Hard to say on the coolant leak, hands and eyes on the machine is the only way to confirm where it is.

The track adjuster is not spring loaded to retract. You are going to have to force it back. Don't loose the ball that is under the set screw.

Sounds like your right side steering clutch may be bad. When you pull the left lever to turn left it disengages the left side clutch, so the left side stops driving (in fact you stop it when you pull further back and apply the brake for a quicker turn). The right side continues to drive when the lef...

My thought is that the throwout bearing carrier at the outer end of it's travel means you have maximum available adjustment available in the future. As things wear the carrier/bearing will move deeper into the slot during adjustments, as the clutch discs get thinner and the pressure plate fingers ge...

The parts catalog shows the earlier units being subbed to the later unit parts including the T164040 shaft. Give Lavoy a call or send an email (postmaster@jdcrawlers.com), he might know of a good late model salvage yard.

Did the dealer do a system wide search for the shaft? There might be one setting on a dealership's shelf somewhere, my dealer has found a couple obsolete parts that way before for me. Is there an upgrade change? Looking at the online parts catalog it looks like that part number is in a group of part...

I can't see it being a safety feature. Without being able to see it, saying why/what has taken place is hard. I suggest you open the left side and compare everything you see in both. Remove the cotter pin and see what happens. The brake has to actuate when you pull the steering lever, but that shoul...

Have you aligned the tracks as covered in the service manual?

The on line parts catalogs are at jdparts.com. Do a model search for 6305 to find the parts catalog for that blade. It may not be what you are looking for as a diagram, but the pages for lift, angle, and tilt show the hose for each going to parts on the valve body. Here is a link direct to that part...

A quality 15W40 diesel engine oil is fine.

The parts catalog for the 6305 (inside mount, 6 way blade) shows the hose/tube locations for the functions.

Play in the bushings is the internal wear and will exist in every pin/bushing interface of the chain. Your concern in installing the master pin is more fit in the chain link pin boss, as they should be a slight interference fit. What is the clearance between the pin and the hole it goes into of the ...

Known brand 15W/40 diesel oil in all but the cars, pick ups, and small engines. I know some fleets run 15W/40 in everything with no issues.

Actually measure the pin hole in the chain rail, the dimension might reveal a clue. I wonder if some one has put 350 chains on your 440IC, those pins are larger OD. Are there any signs of welding on the sprockets?

Good morning and welcome to the board. It would help answer your question(s) if you include the model of your machine. A 1968 JD crawler loader could be a 350 or a 450, and there are some differences that will come into play for at least some things. In this case both were plumbed from the injection...

Welcome to the board. Just a housekeeping item. Posts about 350 machines and newer, like your 450E, should be on the Late Model Board to get best exposure, as technically there are a lot of drive train differences. This post will likely get moved over there when Lavoy, or a moderator, see it. No har...
