NO.: TSB-97-37A-001DATE: March, 1997
MODEL: 1995-97 Eclipse 2.0L Non-turbo
SUBJECT:
POWER STEERING BELT ALIGNMENT AND TROUBLESHOOTING PROCEDURES
PURPOSE
This bulletin contains procedures for checking power steering belt alignment and correcting misalignment.
SYMPTOM AND CONDITION
The customer may complain of conditions related to misalignment of the power steering pump pulley.
AFFECTED VEHICLES
1995-97 Eclipse equipped with the 2.0L Non-Turbo (420A) engine
DIAGNOSIS PROCEDURES
Use the following diagnosis procedures to check the alignment of the power steering belt. If the belt is found to be out of alignment, shim the power steering pump pulley according to the steps in the REPAIR PROCEDURES.
VEHICLES WITHOUT AIR CONDITIONING
First, visually inspect the alignment of the power steering pump pulley to the crankshaft pulley. If belt and pulley misalignment cannot be visually verified, check the alignment with a straight edge as shown in the illustration.
VEHICLES WITH AIR CONDITIONING
Inspect the alignment of the power steering pump pulley by looking at the position where the belt rides on the idler pulley (tensioner). If the belt is riding over the edge of the idler pulley as shown by the overhang in the side view in the following illustration, the power steering pulley is misaligned.
If the power steering pulley is out of alignment, use the following procedures to shim the power steering pump into proper alignment.
1. Remove the bolt holding the power steering pump bracket to the front area of the engine mount. Loosen the remaining two bolts attaching the power steering pump bracket.
2. Add the necessary number of 1 mm shims between the pump bracket and the front engine mount so the pump is moved to where the pulley is in alignment.
Note:
FOR BETTER PULLEY ALIGNMENT ON VEHICLES WITH AIR CONDITIONING:
a. Move the power steering pump closer to the engine (along the adjuster slot in the power steering bracket) then tighten the upper attachment bolt.
b. Tighten the two lower power steering pump bolts, last.
c. Adjust the power steering belt tension by using the idler tension pulley.
3. Go back to the diagnosis procedures to check the belt alignment again before returning the vehicle to the customer.
