STEERING 25 E. PROCEDURE FOR ADJUSTING FREE PLAY/NOISE This procedure to be followed only when there is any noise reported from the Rack and pinion steering gear assembly during vehicle operation. Procedure to be carried out by trained / expert operator. Dismantle the gear assembly from the vehicle and follow the procedure as given under Step 1 Clamp the steering gear assembly properly and check the free pinion torque using dial type torque indicator (Range: 0~0.6 kg-m). Step 2 If the average pinion torque falls below 0.15 Kg-m, tighten the yoke cover to 10º after loosening the Locknut and check the average free pinion torque found between 0.09 to 0.15 Kg-m. NOTE: (This step can also be tried on vehicle level condition without removing the steering gear assy. While carrying out this adjustment, free pinion torque need not be checked. Noise level can be checked in vehicle level ) Step 3 If the average pinion torque found not OK, repeat the step 2 till to achieve the required average free Pinion torque of 0.09 to 0.15 Kg-m. Refer Step 2 photograph Step 4 After achieving correct pinion torque, tighten Locknut to 4 Kg-m torque by supporting the yoke cover with 15mm hexagonal box spanner socket to reassemble the gear in the vehicle and check for the noise by road test.
