JDcrawlers Messageboard

Gee, lots of views, no ideas? My "C" has intermittent power to the left track. When the left track is in certain positions it won't pull and the right one does all the work. I try to steer right and nothing happens. Then I re-engage the right track moving the left one on around a bit, and it will en...

Sometimes you can get a twelve point box end wrench on the square nuts, yet that may not fit all rails and all situations. I finally welded a piece of maybe 3/8" square stock onto a long bolt that I could hold with a heavy padded glove and wedge between the nut and the rail (keep your teeth out of r...

My understanding of the different bolt grades is that those with the higher numbers have higher tensile strength, meaning that if you are trying to separate the bolt (have it "fail in tension") by pulling it by its ends along its length, the higher grade will take more pounds per square inch before ...

I really love the soft "Charmin" feel of foam motorcycle grips on my 450s B&C and get them at the local motorcycle shop. They last several years of consistent use through the extremes of hot and cold in North Idaho. They slip on slightly tight and after a little coaxing, don't require any cement or ...

You might try "Norcan" in Spokane, Washington. They have lots of used tractor parts.

While on the road I found some air horns in a friends garage and blew air through them. They worked perfectly. So I took one apart and found the chamber, the flat round disk, and, ... A spring! I thought, 'Gee, I don't remember mine having springs between the back cover against the disk!' Back home,...

Thanks to all for the continuing stream of ideas. I disassembled them. Yes, there were bugs, mostly paper wasp nests, and I cleaned out all the dirt and crud. Neither the horns nor their trumpets showed any adjustability as I remember. There was just the trumpet, the base with an input slot shaped w...

Most first-time crawler buyers think they know what kind of crawler they want but once they discuss their proposed uses they realize that a different crawler may suit their needs better. Sometimes even a different type of machine is better than a crawler for their proposed uses. I was thinking if y...

If you really want to go and look at this machine, bring somebody with you who knows old Deere crawlers... even if you have to pay them. Minimize your risk as much as you can. I second Ken's advice. I "ran into" a JD Crawler mechanic and asked him about the frozen clutches on my 450B. He explained ...

On the 450A the connection from the steering lever to the clutch/brake is completely mechanical. The input and output shafts of the steering cylinders are the same piece of metal. When the 450A sits awhile the pivots of the linkages inside the clutch housings can get rusted. When you activate the cl...

When I had this problem the wire from the starter button to the starter had broken behind the instrument panel. Also the rubber had split covering the starter button switch. Bought another switch at NAPA, its cover fit my starter button. My unit has had the neutral switch disconnected. If yours is s...

Interesting thread. In North Idaho a mill will not accept logs until a logger presents a standard form contract from the landowner stating location and permission to log. It keeps people from stealing logs from unattended land. The mill then sends to the owner a computer printed statement of every l...

If it is like a 450, there is a setscrew in the brake drum that locks it to its splined shaft. You access it through a plug above the small bearing housing in the final drive, and you will have to look in the top of the clutch housing as you rotate the clutch to see when it is lined up. The setscrew...

I just fixed the same problem on my 450B. The angling frame has a "tab" on each side on which the blade and the curved plate ride, and where the shims would be located. With the blade off, looking at the end of this tab, it had the cross section of a football - worn top and bottom, fat in the middle...

My left clutch engages intermittently and does not pull well under load. The right one seems to work normally. I understand (or as near as I can tell from the manual) that, unlike the 450B whose steering clutches are held engaged by the pressure plate springs, the 450C has a hydraulic "throw in" pis...
