Notice: The timing chain on the LD9 (VIN T) Twin Cam Engine is not
to be replaced with the timing chain from any other model year. The timing
sprockets are different on the Twin Cam engine and the shape of the links
matches the sprockets. Engine damage may result if the wrong timing chain
is used. The timing chain and the crankshaft sprocket must be marked so that
they are reinstalled in the same side facing out at the time of reassembly.
Important: Read the entire procedure before removing the timing chain.
- Mark the timing chain and the crankshaft sprocket outer surfaces for reassembly.
Ensure that this is done in order to prevent noise and increased wear on the
chain.
- Remove the timing chain guides.
- Reload the timing chain tensioner assembly to its "zero"
position. Use the following steps:
3.1. | Form a keeper from a piece of heavy gauge wire. |
3.2. | Apply slight force on the tensioner shoe to compress the plunger. |
3.3. | Insert a small screwdriver into the reset access hole. |
3.4. | Pry the ratchet pawl away from the ratchet teeth while forcing
the plunger completely in the hole. |
3.5. | Install the keeper between the access hole and the blade. |
- Remove the tensioner assembly retaining bolts.
- Remove the tensioner. Ensure all of the slack in the timing chain
is above the tensioner assembly when the tensioner is removed.
- Remove the timing chain.
- Inspect the parts for wear, replace them as required.
- Replace the timing chain shoe or guides if the scoring exceeds
1.12 mm (0.045 in).
