I recently found a D6B to use to move dirt and trees on my property. I don’t have any issues with it but I am wondering why I can’t seem to find anything with my serial number. All I see is 37A657. It’s on the left rear of the frame. Is there something I’m missing?
Welcome to the HEF, Casey Allen. Good to have you. We have the skill and we have the tools and we know how to chat. If you are looking for a Forum, the HEF is where it’s at!!
Welcome also. 36A657 is the Serial Number. Today it would be written 36A00657 because Cat never bothered with the zeros back then. With a machine of that era there won’t be a lot available online, even in the official factory systems. What exactly were you looking for.?
Is there another place that the serial is stamped on these? I’m just looking to find a little more about it. I’d like to know what year it is and for sure what motor is in it.
If the engine is original you should find the same Serial Number on it as you found on the tractor. There are a couple of members here who have access to old documentation which would include Serial Number locations. Production of the 37A started in 1959 so I would hazard a guess your tractor dates to either 59 or 60. Manuals appear to be available. The Operation & Maintenance Guide is SEBU6451. The Parts Manual is UE033764 covering all 37A tractors. EDIT: just so that you are aware. All parts & service information for your tractor will be based entirely on the Serial Number, not the year of manufacture.
Thanks for the info. Here’s a picture for fun.
This is what the Serial Number plate on the engine looks like on a slightly newer (1965) 76A-prefix D6C tractor. Yours should look somewhat similar.
Thanks again for the information. It seems be a decent old machine, but I’ll have to work on it at some point for sure. I just want to have my ducks in a row when that time comes!
I completely agree which is why IMO your first requirement should be to get hold of some manuals.
37A657 is a Direct Drive narrow gauge with D333A engine (4-1/2" bore) built in 1961
Thanks old magnet.
