CAUTION: Do not use automatic transmission fluid in power steering system. Only use MoparT, Power

Steering Fluid, or equivalent.

(9)Fill power steering pump reservoir to correct fluid level.

(10)Connect the negative battery cable on the negative battery post.

(11)Start engine and turn steering wheel several times from stop to stop to bleed air from fluid in system. Stop engine, check fluid level, and inspect system for leaks. See Checking Fluid Level.

POWER STEERING PUMP PULLEY SERVICE

SAGINAW VANE SUBMERGED PUMP (HAM CAN)

REMOVE

(1) Remove the pulley with Puller C-4333 (C-4068) (Fig. 1).

Fig. 1 Pulley Removal (Typical)

CAUTION: Do not hammer on power steering pump pulley. This will damage the pulley and the power steering pump.

(2) Replace pulley if bent, cracked, or loose.

INSTALLATION

(1) Install the pulley with Installer C-4063 (Fig. 2). Do not use the tool adapters.

Fig. 2 Pulley Installation (Typical)

(2)Ensure that the tool and the pulley remain aligned with the pump shaft. Prevent the pulley from being cocked on the shaft.

(3)Force pulley flush with the end of the shaft. With Serpentine Belts; Run engine until warm (5

min.) and note any belt chirp. If chirp exists, move pulley outward approximately 0.5 mm (0.020 in.). If noise increases, press on 1.0 mm (0.040 in.). Be careful that pulley does not contact mounting bolts.

SAGINAW T/C STYLE PUMP

REMOVE

(1)Mount power steering pump assembly in a vise using one of the pump mounting bosses (Fig. 3). Do not clamp the body of the power steering pump in vise.

Do not press or hammer on the shaft of the power steering pump in an attempt to remove the pulley. This will damage the internal components of the power steering pump.

(2)Remove the power steering pump pulley from the power steering pump shaft using Puller, Special Tool C-4333 (Fig. 4).

INSTALL

Do not press or hammer on the shaft of the power steering pump in an attempt to install the pulley. This will damage the internal components of the power steering pump.

(1) Place the power steering pump pulley on the end of the power steering pump shaft. Make sure the pulley is installed squarely on the end of the shaft (Fig. 5).

Fig. 4 Removing Power Steering Pump Pulley

CAUTION: When installing the pulley on the Saginaw T/C style power steering pump. The spacer that is provided with either the replacement power steering pump or pulley MUST be used when the pulley is installed on the pump. The spacer provides for the correct pulley location on the power steering pump to provide correct accessory drive belt alignment. The alignment is critical in controlling accessory drive belt noise. It also prevents the pulley

Fig. 5 Pulley And Spacer Installed On Pump

(3)Insert the Pulley Installer, Special Tool C-4063, (without adapters) through hole in spacer. Then thread it into the end of the power steering pump shaft (Fig. 6). Tighten the installer into shaft.

(4)Hold the Pulley Installer with one wrench so it will not rotate. Turn hex (Fig. 6) down threaded rod of installer pushing the pulley onto the shaft of the power steering pump (Fig. 6). Ensure that the tool and the pulley remain aligned with the pump shaft so pulley does not become cocked on shaft.

(5)Continue to push pulley onto shaft of power steering pump until Pulley Installer, Special Tool C-4063 will no longer turn. This will ensure the spacer provided is fully seated against the front of the power steering pump shaft (Fig. 7).

(6)Remove the Pulley Installer, Special Tool C-4063 from the shaft of the power steering pump. Remove the supplied spacer from the hub of the power steering pump pulley and discard.

POWER STEERING PUMPÐINITIAL OPERATION

CAUTION: The fluid level should be checked with engine off to prevent injury from moving components. Use only MoparT Power Steering Fluid. Do not use automatic transmission fluid. Do not overfill.

Wipe filler cap clean, then check the fluid level. The dipstick should indicate FULL COLD when the fluid is at normal temperature of approximately 21°C to 27°C (70°F to 80°F).

(1)Fill the pump fluid reservoir to the proper level and let the fluid settle for at least two (2) minutes.

(2)Start the engine and let run for a few seconds. Then turn the engine off.

(3)Add fluid if necessary. Repeat the above procedure until the fluid level remains constant after running the engine.

(4)Raise the front wheels off the ground.

(5)Start the engine. Slowly turn the steering wheel right and left, lightly contacting the wheel stops.

(6)Add power steering fluid if necessary.

(7)Lower the vehicle and turn the steering wheel slowly from lock to lock.

(8)Stop the engine. Check the fluid level and refill as required.

(9)If the fluid is extremely foamy, allow the vehicle to stand a few minutes and repeat the above procedure.
