- Place the primary camshaft
drive chain tensioner oil tube (1) in position on the cylinder block.
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.
- Install the primary camshaft drive chain tensioner oil tube bolts.
Tighten
Tighten the primary camshaft drive chain tensioner oil tube bolts to
9 N·m (80 lb in).
- Install the primary camshaft
drive chain.
Important: Do not remove the J 42038
.
- To assist in primary camshaft drive chain installation, use an open
end wrench on the hex cast into the camshaft to provide minor adjustments
to the secondary sprocket position.
- When installing the primary
camshaft drive chain you must set the base engine timing. Base engine timing
is set with cylinder number one at top dead center (TDC) starting the intake
stroke and with the correct camshaft to balance shaft to crankshaft relationship.
To set the correct base engine timing proceed as follows:
5.1. | Rotate the crankshaft until cylinder number one is at top dead
center and the crankshaft sprocket timing mark (6) is at the four o'clock
position using the J 43032
. |
5.2. | Rotate the balance shaft until its timing mark (7) is at
the five o'clock position. |
- Make sure the darkened chain links on the primary camshaft drive
chain are facing toward the front of the engine.
- Center the timing mark (1) on the left hand intake camshaft
between the paired darkened timing links (2) and wrap the chain around
the sprocket. Allow the remainder of the primary camshaft drive chain to drop
into the crankcase area once the timing mark is aligned.
- Fabricate a hook out of wire and feed it down through the right
cylinder head. Use the hook to pull the remainder of the primary camshaft
drive chain up to the right intake camshaft sprocket.
- While pulling the timing chain up to the right cylinder head,
align the darkened chain links with the balance shaft (7) and crankshaft (6)
sprockets.
- Wrap the primary camshaft drive chain around the right intake
camshaft sprocket and align the darkened link (8) with the sprocket's
timing mark (9).
- Make sure all the timing marks are properly aligned with the darkened
chain links.
- Install the primary camshaft
drive chain tensioner shoe (1).
- Install the primary camshaft drive chain tensioner shoe bolt using
the access hole in the cylinder head.
Tighten
Tighten the primary camshaft drive chain tensioner shoe bolt to 30 N·m
(22 lb ft).
- Collapse the primary camshaft
drive chain tensioner using the following procedure:
14.1. | Rotate the ratchet release lever (2) counterclockwise and
hold. |
14.2. | Collapse the tensioner shoe (1) and hold. |
14.3. | Release the ratchet lever and slowly release the pressure on the
shoe. |
- As the ratchet lever moves to its first click, hold the tensioner
shoe inward. Insert a pin through the hole in the release lever.
- The locked ratchet mechanism should hold the shoe in a collapsed
position.
Important: Ensure that the primary camshaft drive chain tensioner release lever
faces toward you before tightening.
- Install the primary camshaft drive chain tensioner (1) and primary
camshaft drive chain tensioner bolts.
Tighten
Tighten the primary camshaft drive chain tensioner bolts to 25 N·m
(18 lb ft).
- Ensure that all the timing
marks (1-9) are properly aligned. Make adjustments as necessary.
- Remove the pin holding the primary camshaft drive chain tensioner
to tighten any slack in the timing chain.
Important: Ensure that each chain guide access plug has an O-ring installed.
- Install the four chain guide access plugs.
Tighten
Tighten the chain guide access plugs to 5 N·m (44 lb in).
- Install a NEW O-ring on
the camshaft position sensor.
- Lubricate the O-ring with clean engine oil.
- Install the camshaft position sensor.
- Install the camshaft position sensor and bolt.
Tighten
Tighten the camshaft position sensor bolt to 9 N·m (80 lb in).
- Install the front engine
lift bracket, hex head bolt and TORX® internal drive bolt.
Tighten
- Tighten the front lift bracket hex head bolt to 50 N·m
(37 lb ft).
- Tighten the front lift bracket TORX® internal drive bolt to
25 N·m (18 lb ft).
