Installation Clean the mating surface of the motor (A) and gearbox. Apply a thin coat of silicone grease to the new O-ring (B) and carefully fit it on the motor. Apply grease (Nippon Grease WR-S or equivalent grease) into the motor shaft (C).

Install the motor on the gearbox by engaging the motor shaft and worm shaft. Note the motor installation position (direction of motor wires (D)). Before tightening the bolts, turn the motor 2 or 3 times right and left about 45 degrees and check for close contact at the mating surface of the motor. Loosely tighten the bolts. Then, holding the motor head firmly, tighten the bolts alternately to tighten the motor securely. CAUTION There must be no foreign material and O-ring trapped in the mating surfaces and there must be no loose contact (lift) at the surfaces. Install the removed parts in the reverse order of removal and note these item: Make sure the motor 2P connector and EPS wire harness 6P connector properly connected. Make sure the motor and EPS wires are not caught or pinched by any parts. After installation, start the engine and let it idle. Turn the steering wheel from lock-to-lock several times. Check that the EPS indicator does not come on. aaa
