Removal Procedure
- Remove the crankshaft rear oil seal housing. Refer to
Crankshaft Rear Oil Seal and Housing Replacement
.
Important: Every 11-crankshaft rotations, 3 of the 5 dark links on the timing chain will
line up with the timing marks.
- Rotate the crankshaft until the correct timing chain and timing marks align:
• | The left hand balance shaft sprocket timing mark (1) is at the
12:00 position |
• | The right hand balance shaft sprocket timing mark (2) is at the
2:30 position |
• | The crankshaft sprocket timing mark (3) is at the 4:30 position |
• | The 3 timing marks (1-3) on the sprockets line up with a
dark link on the chain |
- Remove the balance shaft chain tensioner
bolts.
- Remove the balance shaft chain tensioner.
Installation Procedure
- Collapse the balance shaft chain tensioner
using the following procedure:
1.1. | Rotate the ratchet release lever (2) clockwise and hold. |
1.2. | Collapse the tensioner shoe (1) and hold. |
1.3. | Release the ratchet lever. |
- Slowly release the pressure on the shoe, until the ratchet lever moves
to the first detent and a "click" is heard and felt.
- Insert a pin through the hole in the release
lever in order to lock the tensioner shoe in the collapsed position.
Notice: Refer to Fastener Notice in the Preface section.
Important: Ensure the tensioner release lever is facing outward.
- Install the balance shaft chain tensioner and bolts.
Tighten
Tighten the balance shaft chain tensioner bolts to 10 N·m (89 lb in).
- Remove the pin holding the tensioner to tighten any slack in the balance
shaft drive chain.
- Verify the correct timing chain and timing mark
alignments:
• | The left hand balance shaft sprocket timing mark (1) is at the
12:00 position |
• | The right hand balance shaft sprocket timing mark (2) is at the
2:30 position |
• | The crankshaft sprocket timing mark (3) is at the 4:30 position |
• | The 3 timing marks (1-3) on the sprockets line up with a
dark link on the chain |
