Piston (4) moves up and down inside the bore of each accumulator (2). Nitrogen gas charge (3) has a charge of approximately 5520 kPa (800 psi). Each accumulator is charged with nitrogen through charging valve (1).
Oil enters pressure oil chamber (6) from the brake pump. The oil reaches the pressure oil chamber through outlet port (7). The oil pushes piston (4) upward. The pressure of the oil compresses the nitrogen gas.
When the pressure in the accumulator reaches approximately 14973 ± 345 kPa (2172 ± 50 psi) for the 834K and the 988K or when the accumulator reaches approximately 14485 ± 345 kPa (2100 ± 50 psi) for the 836K, the supply of oil is stopped. When either brake pedal is pushed, oil from pressure oil chamber (6) flows out of port (7) to the service brake control valve. This action applies the service brakes.

EQUIPMENT HYDRAULIC SYSTEM
6.4.1 DESCRIPTION
Fig. 6-20 Pilot valve
The control system of the control valve is of a power assisted type with different levers for the functions: booms lowering/raising and bucket roll-back/dumping.
The control valve spools are actuated by hydraulic connections. The circuit pressure (30 bar) is ensured by a pressure relief valve equipped with an hydraulic accumulator.
It is possible to install, upon request, a third lever controlling a third spool of the control valve, in case it becomes necessary to mount a special type of equipment requiring a third hydraulic function.
A questo proposito, il supporto in cabina é predisposto a ricevere la terza leva di comando.
WARNING
The piloting system of the control valve is equipped with a safety device allowing its cuttingoff. Actuate the cut-off device to lock the control levers in neutral position when the equipment is not in use.
6.4.2 PILOT VALVE
The pilot valve is of a modular type and is composed of two valve assemblies connected by two screws. If the booms or the bucket lever is actuated, the plunger of the pilot valve moves to direct pressurised oil to the port of the equipment control valve selected, moving the corresponding spool.

Adjust Rolling Moment of Drive Pinion Bearing
STEP 50
Install the spacer ring on the pinion shaft.
Note – As per experience the required rolling movement is obtained by use of the spacer ring [e.g. s=8.70 mm (0.34 inch)] available at disassembly.
However, a later checking of the rolling movement must be done.
WARNING
Always wear heat protective gloves to prevent burning your hand when handling heated parts.
STEP 51
Insert the assembled drive pinion into the differential carrier and install the heated bearing inner ring.
