Removal Drain the differential lubricant. See LUBRICATION . Disconnect the clutch pump check valve electrical connector. Remove the clutch pump check valve mounting bolts. See Fig. 1 . Remove the clutch pump check valve by carefully pulling straight out of the differential carrier. Remove the “O” ring seals from the valve. The “O” ring seals may be reused if not cut or damaged. If reinstalling original valve, inspect for damaged, loose, or missing pick up screen, damaged or missing “O” rings, damaged electrical connector, or oil passages restricted by dirt or debris. Installation NOTE: Inspect the clutch pump check valve “O” ring seals to ensure they are not cut or damaged. Replace cut or damaged “O” ring seals with NEW seals. 1. Lubricate the “O” ring seals with Synthetic Gear Oil (12378514 for United States or 88901045 for Canada) or equivalent. Install the “O” ring seals to the valve. Install the clutch pump check valve to the differential carrier by carefully pushing the valve straight in until fully seated. 2. Install the clutch pump check valve mounting bolts. See Fig. 1 . Tighten the bolts to specification. See TORQUE SPECIFICATIONS . Connect the clutch pump check valve electrical connector. Inspect differential fluid level. See LUBRICATION . Fill differential as necessary.

1. Disconnect the brake booster vacuum check valve (1) from the brake booster. 2. If the vacuum check valve (1) needs to be separated from the vacuum hose (3), release and reposition the clamp (2) on the vacuum hose (3) and remove the check valve (1) from the hose (3). 3. If replacing the vacuum check valve (1), remove the grommet (4) from the brake booster and discard the grommet. 4. If removing the vacuum hose (2), take note of the vacuum hose routing then disconnect from the engine intake manifold connection (3) by releasing tension on the vacuum hose clamp (1) and sliding the vacuum hose (2) off the intake manifold connection (3). Installation Procedure Important: A small amount of denatured alcohol can be used as an assembly aid when installing the vacuum check valve and/or grommet. Do NOT use soap. 1. If the vacuum hose (2) was removed, install the vacuum hose into position on the vehicle as noted prior to removal, then connect the vacuum hose (2) to the engine intake manifold connection (3) and secure with the vacuum hose clamp (1). 2. If the vacuum check valve (1) is being replaced, install a NEW grommet (4) to the brake booster. 3. If the vacuum check valve (1) was separated from the vacuum hose (3), install the check valve (1) to the vacuum hose (3). Install and secure the clamp (2) into position on the hose (3). 4. Connect the brake booster vacuum check valve (1) to the brake booster.

1. Disconnect vacuum hose at speed control servo and install a vacuum gauge into the disconnected hose. 2. Start engine and observe gauge at idle. Vacuum gauge should read at least ten inches of mercury. 3. If vacuum is less than ten inches of mercury, determine source of leak. Check vacuum line to engine for leaks. Also check actual engine intake manifold vacuum. If manifold vacuum does not meet this requirement, check for poor engine performance and repair as necessary. 4. If vacuum line to engine is not leaking, check for leak at vacuum reservoir. To locate and gain access to reservoir, refer to Vacuum Reservoir REMOVAL /INSTALLATION . Disconnect vacuum line at reservoir and connect a hand-operated vacuum pump to reservoir fitting. Apply vacuum. Reservoir vacuum should not bleed off. If vacuum is being lost, replace reservoir. 5. Verify operation of one-way check valve and check it for leaks. a. Locate one-way check valve. The valve is located in vacuum line between vacuum reservoir and engine vacuum source. Disconnect vacuum hoses (lines) at each end of valve. b. Connect a hand-operated vacuum pump to reservoir end of check valve. Apply vacuum. Vacuum should not bleed off. If vacuum is being lost, replace one-way check valve. c. Connect a hand-operated vacuum pump to vacuum source end of check valve. Apply vacuum. Vacuum should flow through valve. If vacuum is not flowing, replace one-way check valve. Seal the fitting at opposite end of valve with a finger and apply vacuum. If vacuum will not hold, diaphragm within check valve has ruptured. Replace valve.

NOTE: Hydraulic valve lifters are used; no valve adjustment is required. When valve and/or valve seat is machined, valve clearance is reduced and may cause improper valve operation. Different length push rods are available for correcting clearance. Valve lifter must be collapsed to check valve clearance. 1. With valve cover removed, position piston No. 1 at TDC of compression stroke. Completely collapse cylinder No. 1 intake valve lifter and hold valve lifter collapsed. Using feeler gauge, measure clearance between rocker arm and valve stem. 2. Clearance should be within specification. Refer to COLLAPSED VALVE LIFTER CLEARANCE table. Replace push rod, if necessary, to obtain correct clearance. 3. Position crankshaft as specified. See, in this article, VALVE CLEARANCE CHECKING SEQUENCE table, and check appropriate valves. Replace push rods if clearance is not within specification. 4. If push rod(s) is replaced, ensure corresponding cylinder piston is below TDC. It will be necessary to loosen or remove rocker arm to replace push rod. CAUTION: DO NOT operate or crank engine after installing push rod until valve lifter has leaked down to normal operating position. COLLAPSED VALVE LIFTER CLEARANCE
