probably your bands will clean up just fine, but there is a company in newark, n.j. that sells lining, fairly inexpensive. i redid my case 310 brakes for $38, plus the cost of the rivets, and time spent, about an hour. its on the net, search for brake lining. the also have clutch linings, in almmost any size ya want.

Kent: I would like to talk to you about these Clark crawlers also The American Tractor Company. You can usually find me on Hartparr Oliver site. I have also seen some modified narrow HG Cletracs that were set up the same way. And you may or may not know tha some of the larger Military Cletracs were built by John Deere at the Wagon works.

Bob S.: As noted, Clark parts were acquired by U.S. Tractor after WWII. They built straight blade, manual angle blade, and loaders using essentially Clark design as Models 10/10A, but generally with Continental F124 gas engines as opposed to Clark Waukesha. Another difference is that the Clark blade cylinders (straight blade) are trunnion type, pivoting from midway along the barrel while U.S. Trac pivoted from the top. Early straight blades used LaPlante-Choate blades, probably Clark leftovers. Some models also had a 6000 lb winch, again ala Clark. U.S. Trac logo is winged globe with a dozer atop it pushing a blade of dirt and underneath the words "Around The World". The serial number on a U.S. Trac should be on a plate on top of transmission down from dash and will typically start with "051 thru 054". The hydraulic tank/valve unit may also have a serial number on top, as will the straight blade on rear top center. With due respect I think the Beetle was made by another company prior to WWII, but not certain. Interestingly in the rush to get into production an original U.S. Trac sales brochure from 1949 shows pictures of a Clark "dressed up" as a U.S. Trac. American Tractor of Cherubusco Il. was the sucessor to U.S.Trac, and it was later part of J.I. Case/Terratrac. Loader version sold on Ebay in last week for 1500 and free 500 mile haul, may still be photos at Link ImageEvent.com/61wm300.

I noticed your reply to bob s. and seem very informed on cat dozers. My dad has a D2 cat that was used in farming operation in maybe 1940-1950's. He has kept it in shed and semi-restored. He has past away and now I am trying to at least determine an apprasial price. Would you have any help for me? Thanks!! Kent

Hi Kent, the best place for expert info on your crawler would be the Antique Caterpillar Machinery Owners Club, Link The guys on there collectively have several hundred years knowledge and experience on Cat equipment and are quite willing to share it with others. I'm sure you will find them very helpful.

I just remembered, it was called the Clark Airborne. Weighs 3000 lbs. but doesn't look it. Designed for the U.S. military ca. 1941. It wasn't exactly parachuted, but dropped in by a wooden glider (so I've read). Had a shuttle clutch, a little Waukesha gas engine, and four speeds in forward and reverse. After the war, production rights were bought by U.S. Tractor Corp. in Ohio. They may be the ones that made the Beetle.

Sounds like it's a Clark Air crawler. I've got photos, but don't know how to post to this forum. check the forum for oddball-orphan tractors. The crawler has been discussed recently and I think there are some Internet links. Besides the Clark Air, which was parachuted by the military, there are a few similar crawlers made later, like the Beetle. It may have been adapted from the Clark Air, I'm not sure, but was used, maybe even parachuted into forest fires for . . . fighting fires.

Jdemaris. What is the process to clean a John deere 350b brake band? Mine is out and a bit greasy. In the process of changing seals and O-rings in final and trans. Clutch discs look good and brake has lots of meat on it. JD wants 350.00 for band alone. Final comes off easy, so I will try to clean band.

I've seen some that were soaked in parts cleaner and they worked okay. Also laquer thinner. When I was a field mechanic, used to take an oxy-acetylene torch, hold it a distance from the band, and run it around until the grease cooked out it and it was dry. The brake bands never seemed to be too critical in the 350s (steering, that is) as long as the lining was still there. Winch brake bands are another story. As you probably know, the steering-clutch disks are kind of touchy and have to be right. Deere used to offer heavy duty clutch disks, but in all the years I worked as a Deere mechanic, I never saw them get used. Too expensive I guess and nobody wanted to experiment. I think they were metallic, but again, I've only seen them in the parts book.

I will give it a shot. I have rosebud tip that puts out plenty of heat. I'll just keep it moving. The band isn't all that bad just a slight film. The discs look good just a bit rusty. I have a JD7 tool to set things right.
