HANDLING POWER STEERING
P OWER STEERING (When provided)
Power steering is fitted for lighter steering effort and easy
manoeuvrability. The system consists of steering gear box,
hydraulic pump and hydraulic reservoir suitably mounted and
connected by piping. Pump drive is through belt from engine.
Power assistance is available during normal functioning of
the power steering system.
In case of any failure in hydraulic system, the steering
can be operated mechanically with increased steering
effort for bringing the vehicle to a repair station.
Procedure for oil filling and bleeding the power
steering system.
( Ensure that the reservoir is totally
cleaned before starting the work. )
1. Fill the reservoir nearly full. Crank the engine for 10
seconds without, if possible, allowing it to start. If the
engine does start, shut off immediately. Check and refill
the reservoir. Repeat atleast three times, each time
checking and refilling the reservoir.
2. Check for any leakage in the system and if noticed
take corrective action.
3. Start the engine and steer the vehicle from full left to full
right turn 3-4 times. Add fluid if necessary to maintain
the level up to the filter top.
4. With the engine at steady speed check for bubble /
foaming in the fluid. If present it indicates that air is
getting sucked into the system.
Check the suction line / fittings and correct if necessary.
5. Once the system is bled properly and free from foaming,
there should not be appreciable change in fluid level in
the reservoir, when the engine is started / stop repeatedly.
Top up or remove excess fluid so that the final level is
at ‘H’ mark on dipstick.
6. Now the system is ready for driving.
CAUTION
Do not allow the fluid level to drop significantly or run out
of the reservoir during the above operation. This may
induce air into the system.
Do not start the engine without fluid in the power steering
system. This will result in serious damage to the pump.
NOTICE
Always use recommended brand of fluid from closed
containers. Any dirty fluid poured in the system will result
in damage to pump/gear.
