Removal
NOTICE: During engine repair procedures, cleanliness is extremely important.
Any foreign material (including any material created while cleaning gasket surfaces)
that enters the oil passages, coolant passages or the oil pan can cause engine failure.
NOTICE: Do not rotate the camshafts unless instructed to in this procedure.
Rotating the camshafts or crankshaft with timing components loosened or removed
can cause serious damage to the valves and pistons.
- With the vehicle in NEUTRAL, position it on a hoist. For additional information,
refer to Section 100-02.
- Remove the coolant expansion tank. For additional information, refer to
Section 303-03.
- Remove the RF wheel and tire. For additional information, refer to Section
204-04.
- Check the valve clearance. For additional information, refer to Valve Clearance
Check in this section.
- Remove the timing drive components. For additional information, refer to
Timing Drive Components.
- Mark the position of the camshaft lobes on the No. 1 cylinder for assembly
reference.

in damage to the camshafts.
NOTE:
Mark the location and orientation of each camshaft bearing
cap.
Remove the camshafts from the engine.
- Loosen the camshaft bearing bolts in the sequence shown, one turn at
a time. Repeat until all the tension is released.
- Remove the camshaft bearing caps.
Installation
- NOTICE: Install the camshafts with the alignment slots in the camshafts
lined up so the Camshaft Alignment Plate can be installed without rotating the
camshafts. Make sure the lobes on the No. 1 cylinder are in the same position
as noted in the removal procedure. Rotating the camshafts when the timing chain
is removed, or installing the camshafts 180 degrees out of position can cause
severe damage to the valves and pistons.
NOTE:
Lubricate the camshaft journals and bearing caps with clean
engine oil.
Install the camshafts and bearing caps in their original location and orientation.
Tighten the bearing caps in the sequence shown in 3 stages:
- Stage 1: Tighten the camshaft bearing cap bolts one turn at a time until
finger-tight.
- Stage 2: Tighten to 7 Nm (62 lb-in).
- Stage 3: Tighten to 16 Nm (142 lb-in).
- Install the Camshaft Alignment Plate.

Timing Drive Components.
- Install the RF wheel and tire. For additional information, refer to Section
204-04.
- Install the coolant expansion tank. For additional information, refer to
Section 303-03.
