7.5L Valve Clearance Adjustment
NOTE:
Hydraulic valve lifters are used. No valve adjustment is required. If valve clearance is incorrect, use oversize or undersize push rod to obtain correct clearance.
- Rotate crankshaft in normal operation direction until No. 1 cylinder is at TDC of compression stroke. Using Lifter Bleed Down Wrench (T71P-6513-B), apply pressure to No. 1 intake valve lifter until lifter is completely bottomed.
- Hold valve lifter in this position while measuring clearance between lifter and valve stem. Record measurement. Repeat this procedure for intake valves No. 3, 7 and 8, and exhaust valves No. 1, 4, 5 and 8.
- Rotate crankshaft 360 degrees (one turn). Bleed lifter and check intake valves No. 2, 4, 5 and 6, and exhaust valves No. 2, 3, 6 and 7. Record measurement and compare it to specification. See 7.5L COLLAPSED VALVE LIFTER CLEARANCE table. If clearance is not within specification, use shorter or longer push rod to obtain correct clearance.
