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 gear puller T82T-6256-A to remove the camshaft sprocket and use crankshaft damper removal tool T58P-6316-D to remove the crankshaft sprocket.
- 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.

See Figures 6, 7 and 8
- 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).
See Figures 9 and 10
The crankshaft gear sprocket is not serviced separately from the crankshaft. Do not try to remove the sprocket or you will damage the crankshaft.
Remove the camshaft sprocket as follows:
- Remove the camshaft.
- Use a press to remove the sprocket from the camshaft.
- Remove the thrust plate and sprocket key.
- Inspect the camshaft and related parts for wear and damage.
- Clean the nose of the camshaft and install the thrust plate.
- Place the key in the keyway on the camshaft.
- Heat the sprocket in an oven to 500°F (260°C).
- Remove the sprocket from the oven, align the sprocket keyway with the camshaft key and install the sprocket on the camshaft until it is fully seated. Allow the camshaft assembly to cool before installation
- Install the camshaft in the engine and align the timing marks on the gears.
