This manual was planned and written for the Service Department; its place is in the shop. Use the manual whenever in doubt about correct maintenance procedures. Use it as a text book for training new Service Department personnel who are unfamiliar with John Deere Tractors.

Some 1000 and 2000 Series pumps will not have a serial number plate. A model number (A) will be stamped on the hub of the pump housing. This will aid in pump identification, however, design changes for non-serialized pumps are usually tied to the application or vehicle serial number.

Non-serialized and serialized 1000 Series pumps have different model numbers, however, the designs are the same.
Non-serialized 2000 Series pumps have different designed pressure compensator valves (stroke control valves) and pump shaft rotary assemblies than serialized pumps. Although the designs are somewhat different, the function is the same.

NON-SERIALIZED and SERIALIZED 2000 Series pump differences will be called out in this technical manual. All current designed John Deere Radial Piston Hydraulic Pumps have serial number plates.

They are concise guides for specific-machines. Technical manuals are on-the-job guides-containing only the vital information needed for-diagnosis, analysis, testing, and repair.
