NOTE
Do not remove the primary timing chain lower
guide (1). The primary timing chain lower guide
is not serviced separately. If the primary timing
chain lower guide requires replacement, the oil
pump assembly (2) must be replaced.

6 Remove the primary timing chain (1). NOTE
For ease of removal, remove the chain from the
crankshaft sprocket, bef ore attempting to
remove from the camshaft intermediate
sprockets.

• cracked or broken guide surface (2), and
• cracked or damaged guide base (3).
2 Replace a damaged guide as required.

Figure 6A1 – 133
Primary Timing Chain Lower Guide
1 Inspect the primary timing chain lower guide for the following:
• worn guide surface (1),
• cracked or broken guide surface (2), and
• cracked or damaged guide base (3).
2 Replace the primary timing chain lower guide by replacing the oil pump assembly, refer to
