John Deere JD350 Crawler Tractor and Crawler Loader Service Manual (SM-2063)

What's Covered in This Manual

This is the original factory Service Manual (SM-2063, January 1974 printing) from John Deere Dubuque Works for the JD350 crawler tractor and crawler loader - an earlier machine in the same crawler line as the 350C and 355D covered elsewhere in John Deere's catalog, so make sure you have the manual that matches your specific machine's generation. The JD350 runs a vertical, 3-cylinder, valve-in-head engine available in either gasoline or diesel form, and the manual's serial number explanation shows exactly how to decode the engine type (gasoline or diesel) and cylinder count straight from the tractor's own serial number tag.

The drive train on this machine uses a sliding gear transmission paired with a Hydraulic Direction Reverser, and the manual devotes a full section to each, along with the final drives, steering clutches, and brakes, and a separate section for the optional Power Steering System. Two winch options are covered in detail as well - the No. 3315 Power Winch and the No. 3310 Manual Winch - each with its own dedicated section, reflecting how this crawler could be configured for forestry or heavy pulling work in addition to dozing and loading.

Beyond the drive train, the manual covers the complete engine (basic engine, lubrication, governor and speed control, cooling, fuel systems), the electrical system, the track system, the full hydraulic system, and the loader main frame, boom, buckets and hitches for machines set up as loaders. A trouble-shooting section and a special service tools listing round out the book. For anyone restoring or maintaining a JD350, this manual is the complete original factory reference for every system on the machine.
