4. Remove the bolts, then remove the camshaft hold-

ers from the cylinder head.

5. Lift the camshaft out of the cylinder head, wipe it

clean, then inspect the lift ramps. Replace the

camshaft if any lobes are pitted, scored, or excessively

worn.

6. Clean the camshaft bearing surfaces in the cylinder

head, then set the camshaft back in place.

7. Place a plastigage strip across each journal.

8. Install the camshaft holders, then tighten the bolts

to the specified torque shown on the previous page.

9. Remove the camshaft holders. Measure the widest

portion of plastigage on each journal.

PLASTIGAGE STRIP
If camshaft-to-holder oil clearance is out of toler-

ance:

And the camshaft has already been replaced,

you must replace the cylinder head.

If the camshaft has not been replaced, first check

the total runout with the camshaft supported on

V-blocks.

Rotate camshaft

while measuring.

If the total runout of the camshaft is within toler-

ance, replace the cylinder head.

If the total runout is out of tolerance, replace the

camshaft and recheck. If the oil clearance is still

out of tolerance, replace the cylinder head.

11. Check cam lobe height wear.

Check this area for wear.

Inspection and Adjustment

Brake Pedal

Pedal Height

1. Disconnect the brake pedal position switch connec-

tor, loosen the brake pedal position switch locknut,

and back off the brake pedal position switch

until it is no longer touching the brake pedal.

2.

Lift up the carpet. At the insulator cutout, measure

the pedal height from the middle of the right side of

the pedal pad.

3. Loosen the pushrod locknut, and screw the pushrod

in or out with pliers until the standard pedal height

from the floor is reached. After adjustment, tighten

the locknut firmly.

NOTE: Do not adjust the pedal height with the

pushrod pressed.

Lower the pedal

4.
Screw in the brake pedal position switch until its

plunger is fully pressed (threaded end touching the

pad on the pedal arm). Then back off the switch 1/4

turn to make 0.3 mm (0.01 in) of clearance between

the threaded end and pad. Tighten the locknut firm-

ly. Connect the brake pedal position switch connec-

tor.

CAUTION: Make sure the brake lights go off when

the pedal is released.

PAD

5. Check the brake pedal free play as described below.

Pedal Free Play

1. With the engine off, check the play on the pedal pad

by pushing the pedal by hand.

Free Play: 0.5 - 2.0 mm (0.02 - 0.08 in)

2. If the pedal free play is out of specification, adjust

the brake pedal position switch.

CAUTION: If the pedal free play is insufficient, it

may result in brake drag.
