STEERING 17 iii. HYDRAULIC SYSTEM AIR BLEEDING : NOTE: Before proceeding to bleed the system:  All pipes and hoses are securely fitted and fastened.  Always use recommended oil from closed containers. Any dirty oil poured in the system will result in damage to pump / gear. CAUTION: It is recommended to use the strainer present in the reservoir while pouring the steering oil in the steering reservoir to avoid entry of dirt and contaminants into the hydraulic circuit.  Fill the reservoir nearly full. Crank the engine for 10 seconds, if possible, without allowing it to start. If the engine does start, shut off immediately. Check and refill the reservoir. Repeat at least three times each time checking and refilling the reservoir. CAUTION: Ensure that the oil does not drop down to the lower level of reservoir or run out of the reservoir; to avoid air induction into the system.  Start the engine and check for any leakage in the system and if noticed take corrective action.  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 ‘MAX’ mark on the reservoir CAUTION: Do not force the wheel against lock position.  With the engine at steady speed, check for bubble / foaming in the oil. If present, it indicates that air is getting sucked into the system. Check the suction line fittings and correct if necessary.  Once the system is bled properly there should not be any change in oil level in the reservoir if the engine is started & stopped repeatedly.  Now the system is ready for driving - top up or remove excess oil so that final oil level is at ‘MAX’ mark on the reservoir. CAUTION: Do not start the engine without oil in the power steering system. This will result in serious damage to the pump. If the oil level fluctuates when turning the steering wheel and oil overflows after engine is stopped, it indicates that the bleeding was not performed perfectly. It can cause noise and early damage to the pump in this case one should again repeat the bleeding procedure. Do not load the system until it is bled properly. Severe damages could occur otherwise. iv. TOE IN ADJSUTMENT : 1. To adjust the “TOE” loosen the lock nut and hold the OBJ assembly with spanner to avoid the rotation. 2. Loosen or tighten the tie rod tube as needed. 3. While adjusting the “TOE IN”, adjust the length of both tie rods by rotating in same direction such that their lengths remain equal at all times. 4. The Toe in value should be in the range 2- 5mm. NOTE:  Ensure that number of threads of exposed out of the lock nut is same on LH and RH side.  For vehicles with ESP, Steering Angle Sensor (SAS) calibration has to be done after wheel alignment.
