I’m looking for owners manual or maintenance manual for a HD6G S#6-26726. Crawler runs but, has an oil leak that I’m trying to figure out where it is coming from. It is slinging oil all over the front ( belts, alternator and radiator). I’ve seen manuals on eBay but, not sure if they are for my crawler. If you have info that can lead me in right direction I would appreciate it. Thanks in advance.

I like having the real book, but until you do. General Gear in Idaho a seller of after market steering clutch parts had lots of crawler tractor manuals on their site.

General Gear has a downloadable service manual for the early HD6 and also a parts manual for the later series HD6.

Thank you Ray 54 and Les Kerf for the information. Are manuals sold by serial numbers?
