David Brown Case 885, 885N, 995, 1210, 1212, 1410, 1412 Tractor Service Manual (P/N C4077-90960)

• 89-page J I Case (David Brown) shop manual PDF covering Models 885, 885N, 995, 1210, 1212, 1410, and 1412.
• Engine coverage is configuration-specific: the 885 uses the 3-cylinder 355011, 164 cu. in. diesel; the 995 uses the 4-cylinder 455071; the 1210/1212 use the 455031; and the 1410/1412 use the 455011. The 4-cylinder engines are 219 cu. in., with the 1410/1412 also receiving dedicated turbocharger coverage.
• Transmission coverage separates the 885/885N six- and twelve-speed synchromesh units, the 995 twelve-speed synchromesh, the different twelve-speed design used in the 1210/1410, and the 1212/1412 Hydra-Shift with its four-speed hydraulic planetary section and three-range constant-mesh gearbox.
• Build differences are identified where they affect repair work. These include the early 995 front support arrangement before serial no. 934315, the 1210 clutch change at serial no. 11154230, and the August 1972 engine-block suffix markings used to identify Borg & Beck ("B") versus Laycock ("L") clutch installations.

Component Documentation

Front axle coverage is split by configuration rather than treated as one generic assembly. The two-wheel-drive section covers wheel bearings, spindles, pivot pins, axle main member, tie rods, and toe-in, including the shim-adjusted 885N hub. The four-wheel-drive axle section is specifically for the Model 1210 4WD and goes into the axle assembly, final drives, front differential, drive shaft, and transfer gearbox, including pinion and spacer-setting work.

Steering coverage distinguishes manual steering from hydrostatic power steering. Power steering is optional on the 885, 995, and some 1210 tractors, while it is standard on the 1210 4WD, 1212, 1410, and 1412. The 885 uses a roller-type pump with a separate reservoir; the other power-steering configurations use a gear pump with an integral reservoir. Side-mounted and transverse steering-cylinder arrangements are both covered, along with bleeding, pump, cylinder and steering-valve overhaul, and pressure diagnosis.

Engine repair content goes well beyond tune-up data. It covers tractor splitting and engine removal, cylinder head service, rocker gear, valve settings, timing gears, camshaft, pistons and rings, crankshaft and bearings, oil pump and relief valve, water pump, and the 1410/1412 turbocharger. The diesel section covers C.A.V. and Simms pump timing and R&R, governor/idle settings, fuel-system bleeding, injector testing and nozzle overhaul. It does not provide an internal injection-pump rebuild procedure. Electrical coverage centers on Lucas alternator/regulator and M45/M50 starter testing and overhaul, including 8TRD/14TR regulator schematics, diode, rotor, stator, armature, and solenoid checks rather than a full tractor wiring-harness diagram.

The Selectamatic section documents depth control, height control, traction control (T.C.U.), remote-cylinder operation, hold and by-pass valves, spool and latching valves, rockshaft ram cylinder, top-link sensing unit, hydraulic pumps, filters, three-way and remote valves, troubleshooting, pressure checks, bleeding, and linkage/control adjustments. Pump arrangement changes with the tractor: the 1210, 1212, 1410, and 1412 use a front-mounted crankshaft-driven pump, while the 885/885N/995 arrangement is driven from the PTO housing. PTO repair coverage includes the 885/995 two-speed unit, two-speed units on the 1210/1212/1410/1412 when equipped, plus single-speed and reversible-shaft arrangements for the 1410/1412. Rear final drives, differential lock, bevel-pinion setting, drum and disc brake systems, and brake adjustment are also covered.

Specification Highlights

• Engine setup data includes 0.010 in. cold valve clearance, 650–700 RPM low idle, and a 90 ft-lb final cylinder-head fastener torque. Cooling capacity is model-dependent: 9 qt for the 885, 14-1/2 qt for the 995, and 15 qt for the 1210/1212 and 1410/1412.
• Power-steering test pressure is 700 psi on the 885 with separate reservoir and 1000 psi on the other power-steering systems. Selectamatic pump relief pressure is 2000 psi on all models. Hydra-Shift diagnosis for the 1212/1412 includes operational tests, pressure testing, sequence-valve checks, and brake-band adjustment; the specified relief setting is 71–75 psi. Injector opening pressure is 2575 psi in service, with 2725 psi specified for a new injector assembly or new spring.
• Factory tooling references include Case tools 964172 and 964173 for steering-valve seal/centering-spring work, DB 8208 for bevel-pinion setting, and David Brown 961977 and 962234 for model-specific Selectamatic pressure testing.

Representative illustrations include the Model 1210 4WD front differential and drive-shaft exploded view, the basic power-steering schematic, the 1410/1412 turbocharger exploded view, Hydra-Shift pressure-gauge and early-cover test-point drawings, the disc-brake exploded view, and the Selectamatic hydraulic-system schematic.

The manual also calls out repair traps that are easy to miss without the factory data. Using overly long bolts in the lower timing-cover locations can force the engine front plate forward, causing an oil leak and possible damage. On the three-cylinder engine, turning the camshaft or crankshaft with the timing gears removed can cause piston-to-valve interference. During gear-type power-steering pump repair, driving on the shaft end can damage the pump bearings.

Because the covered repair work includes tractor splitting, heavy axle and transmission assemblies, high-pressure hydraulic and injector testing, and brake service, use proper supports, pressure isolation, and normal shop safety practices before disassembly or testing.
