TEST NO. 2 - STEERING CIRCUIT AND RELIEF VALVE (SHEET 5 OF 5)
If indications recorded in steps t and v above are less than indications
obtained at same pressure in test no. 1 steps p and r there is leakage in
the circuit. Leakage can be caused by one of the following:
(1) Worn or damaged piston in a steering cylinder assembly; perform steering
cylinder assembly test (page 3-560).
(2) Worn or damaged parts in steering gear. Perform steering cylinder assem-
bly test (page 3-560) to isolate fault. If steering cylinder assemblies
check okay, then steering gear is defective. Remove, replace, and repair
steering gear (page 3-510).
Disconnect flowmeter (12) hoses (10 and 11) and remove fitting (9).
Remove cap (5) from fitting (4).
Remove plug from hose (3) and reconnect hose to fitting (4).
Reinstall quick disconnect coupling and adapter (7) in fitting (8).
Reinstall fill cap (2) in hydraulic reservoir. Close and lock access door in
front of loader.
Remove flowmeter from loader cab.
Before performing following step, warn personnel to stay away from sides
of loader between front and rear chassis. Failure to do so will cause
death or serious injury to those personnel due to chassis pivoting and
crushing them. If personnel are injured, obtain medical assistance
af. Start engine and turn steering wheel through several complete turns to bleed
any air from hydraulic system. Turn off engine and check for hydraulic oil
leakage at connections.
