Timing Chain Component (RH) Installation Note

WARNING: This page is about a different car, the 2003 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

Rotate the crankshaft clockwise until the keyway is in the 3 o'clock position.

Position the mark on the exhaust camshaft to 12 o'clock position.
Position the mark on the intake camshaft to 3 o'clock position.
NOTE:
- Install the timing chain (RH) by aligning the colored links on the timing chain (RH) with the marks on the timing sprockets.

Install the timing chain (RH) in the following order.
1. Timing chain crankshaft sprocket
2. Chain guide
3. Timing chain
4. Tensioner arm
5. Chain tensioner
NOTE:
- The chain guide should be installed to the actuator and allowed to hang freely when the bolts are installed. Do not hold the chain guide in an upward position when the bolts are installed. The actuator causes a wear O-ring and this installation method will allow that wear to continue.
NOTE:
- If timing marks in the timing chains are not evident, use a permanent-type marker to mark the crankshaft and camshaft timing marks on the timing chain.
  1. Mark any link to use as the crankshaft timing mark.
  2. Count 29 links from the crankshaft timing mark and mark as the exhaust camshaft sprocket timing mark.
  3. Continue counting to 42 mark the link as the intake camshaft sprocket timing mark.

CAUTION:
- Install the camshaft journal thrust caps last, or damage to the thrust caps may occur.
Tighten the bearing caps evenly in several passes in the order shown in Fig 5.
NOTE:
- After adjusting the camshaft end play using the thrust caps 1R and 5R, tighten the other bearing caps.
