REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4 and 5
- Drain the cooling system and remove the front cover.
- Crank the engine until the timing marks on the camshaft and crankshaft gears are aligned.
- Use a gear puller to removal both of the timing gears.
- Before installing the timing gears, be sure that the key and spacer are properly installed. Align the gear key way with the key and install the gear on the camshaft. Be sure that the timing marks line up on the camshaft and the crankshaft gears and install the crankshaft gear.
- Install the front cover and assemble the rest of the engine in the reverse order of disassembly. Fill the cooling system.
- Follow the procedures for timing gear cover removal and installation and remove the front cover.
- To remove the crankshaft gear, install gear puller (Ford part) no. T83T-6316-A or equivalent and using a breaker bar to prevent the crankshaft from rotating, remove the crankshaft gear. To install the crankshaft gear use tool (Ford part) no. T83T-6316-B or equivalent while aligning the timing marks as shown in the illustration and press the gear into place.
- The camshaft gear may be removed by taking out the Allen screw and installing a gear puller, Ford part no. T83T-6316-A or equivalent and removing the gear. The gear may be replaced by using tool (Ford part) no. T83T-6316-B or equivalent. Tighten the Allen head screw to 12-18 ft. lbs. (16-24 Nm).
MEASURING TIMING GEAR BACKLASH
See Figures 6 and 7
Use a dial indicator installed on block to measure timing gear backlash. Hold the gear firmly against the block while making the measurement. If excessive backlash exists, replace both gears.
