Secondary Timing Belt

SECONDARY TIMING BELT

REMOVE OR DISCONNECT
1. Secondary timing belt actuator. Secondary Timing Belt Tensioner Plate and Actuator
2. If the belt is to be used again, mark the direction of rotation.
3. Tensioner pulley/arm assembly.
4. Timing belt, by carefully sliding it off of the pulleys. Do NOT bend, kink, twist, or pry on belt as damage may occur.
- "Kinking" is folding belt so that the diameter at any point is less than 60 mm (2.36 inches).

INSPECT
- Belt teeth and back side of belt for cracks, tears or other damage. Replace the belt if any of these conditions are found. Overall belt width below 32 mm (1.26 inches) indicates a side wear condition.

INSTALL OR CONNECT

Figure 18. Timing Belt Routing:

1. Timing belt by routing it around the idlers and sprockets. Do NOT bend, kink, or pry on belt as damage may occur.
A. Start at intermediate cam sprocket and work counterclockwise.
B. Make sure the belt is installed in direction of rotation.
C. Engage teeth into all sprockets, place rubber hose behind belt at intermediate sprocket and accumulate slack at tensioner location.

2. Tensioner pulley to mounting base.
- Use flat magnet, tape or cup plug to hold pivot tube in pulley during this step. Otherwise, pivot tube may fall out.
- After starting pivot bolt, rotate arm counterclockwise to position square lug at 6 o'clock.

TIGHTEN
- Bolt to 50 Nm (37 lb. ft.).

IMPORTANT: The arm bushing and pivot must be clean and NOT LUBRICATED.

Figure 19. Timing Marks:

3. Actuator and side plate.
- Make sure the reference marks on the sprockets are properly aligned.

INSPECT
- The installed actuator assembly to assure it is free and rotates under its own weight.

4. Pull paper clip (retaining pin), using needle pliers, and discard allowing the pulley to move into the belt.
5. Remove sprocket clamp, and any other belt-holding devices.
6. Gently rotate the tensioner pulley 10-15 Nm (89 lb. in. - 11 lb. ft.) counterclockwise into the belt using the square lug in the arm and engage the actuator shaft in the arm socket.
7. Rotate the engine clockwise (the direction of engine rotation as viewed from the front) three times to seat the belt. Check the sprocket reference marks to insure correct timing. DO NOT REVERSE ENGINE ROTATION.
8. Repeat step 6, and apply 16-20 Nm (12-15 lb. ft.) of torque to set the initial tension on the belt.

INSPECT
- Tensioner pulley position. Refer to procedure in "Secondary Timing Belt Tensioner Plate and Actuator".
