Important: The camshaft drive sprockets have numbered slots that must be aligned
with the pins on the camshafts.
When the numbered camshaft drive sprocket slot is properly installed
on the camshaft pin, the reference mark near the gear of the drive sprocket,
will align with the notch on the engine rear cover (1,2,3,4).
- Install the camshaft drive sprockets.
Ensure the camshaft
pins are installed in the correct numbered slot on the drive sprockets.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
Important: Use new camshaft drive sprocket bolts, the old bolts are not reusable.
- Install the camshaft drive sprocket bolts with washers.
Tighten
| • | Use the relevant J 42069-1 or the J 42069-2 to hold
the camshaft drive sprockets and the camshafts in place while tightening the
camshaft drive sprocket bolts. |
| • | Use the J 36660-A
to tighten the camshaft drive sprocket bolts to 50 N·m (37 lb ft)
on the first pass, 60 degrees on the second pass and 15 degrees
on the third pass. |

- Install
the crankshaft drive gear.
- Install the NEW crankshaft drive gear bolt, hand tighten only.
Important: Install the alignment pin in the correct
numbered, alignment slot on the camshaft gear.
- Install the camshaft gear.
Notice: Refer to Fastener Notice in the Preface section.
Important: Use a new camshaft gear bolt. The required
tightening method will stretch to its yield point, therefore, the bolt is not reusable.
- Install the camshaft gear bolt.
| • | Use the kits tools J 42069-1 and J 42069-2 within the J 42069
to hold the camshaft gear and
the camshaft in place while tightening the camshaft gear bolt. |
| • | Tighten the camshaft gear bolt. |
Tighten
Tighten the camshaft gear bolt to 50 N·m
(37 lb ft), plus 60 degrees, plus 15 degrees.
Notice: Ensure both components are aligned correctly or serious engine damage
will occur.
Important: Do not rotate the crankshaft if the camshaft
is not locked in place with 1-2 and 3-4 camshaft locks, J 42069
, and J42069-2.
Important: Do not rotate the camshafts unless the crankshaft
is at 60 degrees BTDC or valves may contact the pistons.
- Install the timing belt and ensure proper alignment. Refer to
Timing Belt Replacement
.
- Install
the J 42065
in order to hold
the drive gear and tighten the bolt using the J 42098
.
