- Loosen the alternator mounting bolts, release the belt tension and remove
the alternator belt.
- Remove the attaching bolts and remove the upper front cover and gasket.
Rotate the engine in the normal direction of rotation until the camshaft pulley
mark aligns with the V-notch at the top of the front housing. The notch in
the crankshaft pulley will now be aligned with the arrow on the front housing,
unless the belt has jumped time.
- With brake pliers or another suitable tool, remove the tensioning spring.
Now, remove the bolt from the tensioner and remove the tensioner.
- Inspect the tensioner for bearing wear. It should rotate freely and smoothly.
If not, replace it.
- Make sure the belt remains engaged at all three sprockets and that crankshaft
and camshaft sprockets are properly in time. Locate the tensioner on its swivel
pin with the slot through which the mounting bolt passes centered over the
bolt hole. Install the bolt, but do not tighten it.
- Install the tensioner spring. With a wrench on the crankshaft pulley, turn
the engine in the normal direction of rotation (clockwise) exactly two full
turns until the timing marks are again aligned. Torque the lockbolt to 28–38
ft. lbs.
- Install the upper cover and alternator belt in reverse of removal. Replace
the cover gasket and torque the bolts to 57 ft. lbs.
