Military Cletracs / New M2 tracks
Last post by CDXXVII - April 11, 2026, 04:23:07 PMThere is a company manufacturing new halftrack tracks. They can make them for the Cletrac also although the tread design does not match the original Cletrac tread.

Last post by CDXXVII - April 11, 2026, 04:07:25 PMHi,
The Cletrac HG and Oliver OC3 are pretty common since there were many built over more than 10 years. They are close cousins with similar appearance. The manufacturer's plate can be found on the bell housing. If present, it will say what model and serial number. From the serial number you can determine the year of manufacture.
Most were used hard so I would inspect the frame where it attaches to the transmission and where it attaches to the track frame.
I can't say to much about the value. I see parts machines asking $500-$800 and runners $2000-$3000. The 68" gauge machines are less common.

Last post by Skiroule69 - April 06, 2026, 03:08:04 PMHello everyone! I'm new and glad to be here! Might as well get right into it! Roughly a month ago, my high school buddy's dad passed away and left him all the equipment, vehicles, and tools. Due to lack of storage space, he's going to be liquidating a few things. When he asked me if there was anything I was interested in, I immediately spoke up for his dad's vintage snowmobile (my main addiction) and the Cletrac that I haven't seen in 30+ years.
Back then it still ran and was usable, but I gather it has sat for decades and the engine is now seized. Not long before his dad passed, he had given it a diesel fuel enema and was trying to get it freed up. Beyond that I have no idea what condition it's in. I wish I could provide you guys with information on a year and model, but the 15 year old kid I was then didn't pay attention! All I remember is that it had a pretty wide stance, sat up off the ground a bit and was stick control (so not an early model with a steering wheel).
I've been looking at pictures and wonder if it's an HG-68, but I'm not 100% on that. I called 'dibs' on it for now, but while he's sorting through the estate, I'm trying to gather some information on what I should be on the lookout for when I finally am able to see it up close, and a very general ballpark value. My buddy hasn't got a clue what it's worth, so I'm trying to come up with a baseline to start with that's fair for both of us.
I know very little about these machines beyond what I've watched on Youtube. Besides checking track, sprocket, and roller condition what else should I be on the lookout for? As I gain more information I'll keep you guys updated. I'm excited to finally see it once he gives me the word. His dad was always a really nice guy to me, and I'm thrilled with the idea of resurrecting one of his old machines.

Last post by CDXXVII - March 21, 2026, 08:10:06 PMCarl,
I'm not sure if I am stating the obvious but have you tried Zimmerman Oliver Cletrac in Ephrata Pennsylvania USA?
Been in business for about 40 years. Very knowledgeable.
I worked in Darwin Lanc in 2012 and stayed in Preston. Really enjoyed the area.

Last post by jimmar - March 14, 2026, 03:02:48 PMHello, I recently purchased a 1942 AG3H with the 00C engine but haven't found any available parts yet. Will let you know if I do. Fortunately I don't need anything for it yet as it's in pretty good shape. Just needs some new paint.

Last post by Robert Barbour - March 11, 2026, 02:49:05 AMAll of my crawlers have the double cut sprocket with an odd number of teeth except my 1940 D8, some of my Cletrac's go back to the thirties. If that idea was patented the patent has long expired. it is common practice today.
