Part of the John Deere Parts Manuals.
Part numbers for the 85G excavator are settled here: John Deere parts catalog PC11200, 600 pages of exploded views. The John Deere 85G parts manual PDF numbers every piece on the machine, from track systems and axle hydraulics through bucket teeth, control linkage, control and load holding valves, and the swing bearing and its mounting hardware. Each callout is paired with its part number, quantity, and the substitution notes that tell you when a number has been superseded. Hardware is spelled out to the detail that decides a parts order: an ISO 70 A relay, a 50A fuse on the harness pages, a 3400mm refrigerant extension hose for the cab air conditioning. Bookmarks and a live text layer put you on the right illustration in seconds.

John Deere 85G Common Problems This Manual Covers
John Deere 85G hydraulic hose and fitting part numbers hard to match on the main pump lines
Start at the lines, hoses and fittings group on page 466, which opens with the suction lines, and trace each callout number to its listing. Where a hose or sleeve is sold by cut length, the remarks column gives it as CTL, so measure your old line end to end and compare before you order.
Manual Section: Lines, Hoses & Fittings p. 466Blown fuses and bad relays, need correct amperage and part numbers for the electrical panel
Pull the fuse and relay listings in the electrical section starting on page 152. Verify amperage before you swap anything: the 50A fuse is called out on page 173 and the ISO 70 A relay appears on page 119. Order by the listed part number, not by the color of the plastic body.
Manual Section: Vehicle Electrical Systems p. 173Cannot identify the correct seal kit or rod part number for boom, arm, or bucket cylinders
Open the hydraulic cylinders group, pages 536 through 557, where the arm, blade, boom, bucket and swing cylinders are listed cylinder by cylinder. Every seal, wear ring, rod guide and bushing carries its own part number, so match the full seal set against your cylinder before you order.
Manual Section: Hydraulic Cylinders p. 536Track chain, idler, and roller part numbers unclear when ordering undercarriage components
Go to the track systems pages in the wheels, tires and tracks group, pages 46 through 71. Match each roller, idler and chain callout to its listing, and check the Serial No. column against your machine's serial number before you order.
Manual Section: Wheels & Tires & Tracks p. 46Fuel filter and fuel hose part numbers hard to pin down on the engine auxiliary pages
Check the external fuel supply group in the engine auxiliary section, which begins on page 124. The fuel filter is listed as MIU802997 on page 143, and bulk hose is sold by cut length, 250 mm on page 145, so measure before you order. Supersessions are noted in the remarks column, so a replaced number points you to the current one.
Manual Section: Engine Auxiliary System p. 124Solenoid and relief valve part numbers difficult to locate in the control valve assembly
Work from the excavator section opener on page 342 into the control and load holding valve group, pages 426 through 465. Match the solenoid valve and relief valve callouts in the exploded view to their listings, and check the listed quantity before you order.
