Part of the Case Repair Manuals.
This 89-page Ji Case / David Brown Shop Manual covers the 885, 885N, 995, 1210, 1212, 1410, and 1412 tractors, one factory document for the whole family instead of guessing which pages apply to your rig. Inside you get full Selectamatic hydraulic lift system coverage, a spool valve and control valve overhaul walkthrough, plus troubleshooting for the diesel fuel system when your tractor won't start or won't lift. You'll also find the front axle, transmission, differential, and clutch procedures laid out the way David Brown techs actually worked them. Set spool valve total movement within 0.001 inch of the dimension etched on the valve itself, and confirm your minimum traction control position before you touch the lift arms. No more flipping through a stack of loose photocopies hoping you grabbed the right model. Pull it up on your phone at the tractor, jump straight to the Selectamatic section through the bookmarks, and get the job done right the first time.

Ji Case / David Brown 885 – 1412 Series Common Problems This Manual Covers
David Brown 995 diesel engine missing and surging while running, black smoke from exhaust
Check the fuel system troubleshooting chart on page 32 and drain the water trap, since water contamination is the top cause of constant misfiring. Replace the fuel filter per the maintenance schedule on page 33, bleed air from the injection lines, and confirm the engine settles to the specified 650 to 700 RPM low idle on page 4.
Manual Section: Diesel Fuel System: Troubleshooting p. 32Engine cranks normally but won't fire and start in cold morning weather
Run the electrical system checks on page 40 to rule out weak battery voltage or slow starter draw before blaming the fuel side. If cranking speed is normal but the engine won't fire, pull the rocker cover and verify valve tappet clearance is set to 0.010 inch per page 4; tight valves bleed off compression and prevent starts.
Manual Section: Electrical System: Troubleshooting p. 40Hydraulic lift fails to raise the bush hog or other rear implement
Trace the circuit on the hydraulic schematic on page 73 to isolate whether the pump, control valve, or ram cylinder is causing the lift failure. Pull the control valve spool and measure its total travel; it must fall within 0.001 inch of the dimension etched on the valve body per page 83. Check the suction filter for debris too.
Manual Section: Selectamatic Hydraulic System p. 73Splitter gear stuck jammed in low position, transmission won't shift into high range
Work through the transmission operational checks starting on page 49 before pulling the top cover; inspect the shift rail detent and splitter fork for burrs causing the jam. On 885, 885N, and 995 models, confirm the combined transmission, differential, and hydraulic reservoir holds its full 24 quart capacity from page 76, since a low level makes shifts bind or feel notchy.
Manual Section: Transmission: Checks and Adjustments p. 49Steering wheel spins too easily with almost no resistance during normal field operation
Open the power steering pressure test procedure on page 16 to isolate whether the pump, relief valve, or cylinder is at fault. Check the reservoir fluid level and bleed trapped air from the lines, a common cause of low steering resistance. Confirm engine idle holds at the specified 650 to 700 RPM, since a slow pump won't build flow.
Manual Section: Power Steering: System Operating Pressure p. 16Frequently Asked Questions
How to reset the hydraulic control valve on a David Brown 885?
To adjust the hydraulic control valve on a David Brown 885, clamp the control valve assembly in a soft-jawed vise and mount a dial indicator against the adjusting nut end of the spool valve. Adjust the inner nut so that the total movement of the spool valve is within 0.001 inch of the dimension etched on the valve, then tighten the outer nut. p. 83
What are the torque specs for the main bearing bolts on a David Brown 995?
For 4-cylinder engines, such as the David Brown 995, the main bearing retaining cap screws should be tightened to a torque of 140 ft.-lbs. After tightening, bend the corners of the tab washers against the flats of the cap screw heads. p. 29
How to reset the traction control mode on a David Brown 1412?
To adjust the traction control on a David Brown 1412, set the selector dial to T.C.U. position. Loosen the locknut on the traction control screw, turn the screw in or out until it just contacts the traction control valve, and then turn it one additional turn from this contact point. p. 79
How to adjust pickup point for weight transfer on David Brown tractor?
The "pickup point for weight transfer" is related to the traction control system. To adjust, set the selector dial to T.C.U. position and move the control lever fully forward to increase traction control pressure. The proper position is determined with the implement in working position and the tractor moving at desired speed. p. 75
