Next turn the center spindle on tool T10052 evenly and strait until the hub separates from the taper of the camshaft.

How To Step 34

Remove camshaft seal using extractor tool 3240. Inspect camshaft for possible groove from old seal wearing on camshaft seal surface area. Lubricate the seal lip of cam seal with clean motor oil and using tool 10-203 tap new cam seal into place. If a groove existed on the camshaft, locate the new seal a few millimeters outward on the camshaft so that it rides on a new surface area.

How To Step 35

Install camshaft hub to camshaft so that the hub aligns or centers with the timing mark on the rear timing belt cover. Torque camshaft hub to 74 ft lbs using counter holding tool T10051.

How To Step 36

Install camshaft sprocket onto the hub leaving the (3) 13mm bolts hand tight at this time. Line up the camshaft sprocket alignment holes with the hub and install tool locking pin 3359.
