not a torque-to-yield design.
6. Tighten the bolts in sequence using the following steps and torque values:
Step 1: Tighten bolts 1-8, 27 Nꞏm (20 ft. lbs.).
Step 2: Verify that bolts 1-8, all reached 27 Nꞏm (20 ft. lbs.), by repeatingstep 1 without loosening the bolts.

6. Hold the camshaft with Special Tool 8428 Camshaft
Wrench , while removing the camshaft sprocket
bolt and sprocket.
7. Using Special Tool 8428 Camshaft Wrench, gently
allow the camshaft to rotate 5° clockwise until the
camshaft is in the neutral position (no valve load).
8. Starting at the outside working inward, loosen the
camshaft bearing cap retaining bolts 1/2 turn at a
time. Repeat until all load is off the bearing caps.
CAUTION: DO NOT STAMP OR STRIKE THE CAM-
SHAFT BEARING CAPS. SEVERE DAMAGE WILL
OCCUR TO THE BEARING CAPS.
NOTE: When the camshaft is removed the rocker
arms may slide downward, mark the rocker arms
before removing camshaft.
9. Remove the camshaft bearing caps and the
camshaft.
INSTALLATION
1. Lubricate camshaft journals with clean engine oil.
NOTE: Position the left side camshaft so that the
camshaft sprocket dowel is near the 1 o’clock
position, This will place the camshaft at the neu-
tral position easing the installation of the camshaft
bearing caps.
2. Position the camshaft into the cylinder head.
3. Install the camshaft bearing caps, hand tighten the
retaining bolts.
NOTE: Caps should be installed so that the
stamped numbers on the caps are in numerical
order, ( 1 thru 4 ) from the front to the rear of the
engine. All caps should be installed so that the
stamped arrows on the caps point toward the front
of the engine.
4. Working in 1/2 turn increments, tighten the bearing
cap retaining bolts starting with the middle cap
working outward.
5. Torque the camshaft bearing cap retaining bolts to
11 N ꞏm ( 1 0 0 i n . l b s . ) .

(Two links marked during removal).
7. Using Special Tool 8428 Camshaft Wrench, rotate the camshaft until the camshaft sprocket dowel is aligned with
the slot in the camshaft sprocket. Install the sprocket onto the camshaft.
CAUTION: Remove excess oil from camshaft sprocket bolt. Failure to do so can cause bolt over-torque
resulting in bolt failure.
8. Remove excess oil from bolt, then install the camshaft sprocket retaining bolt and hand tighten.
