The cam chain tension adjuster is maintained to proper tension automatically.

| Note if it is difficult to compress the plunger because of internal engine oil, disassemble the adjuster by releasing the inner circlip “c” and spill out the oil. |
| Caution do not turn the adjuster body until the outer circlip “a” exceeds the groove “b”. If the inner circlip “c” is caught in the groove “b”, plunger may not go out automatically from the adjuster body even if pushing force is applied on the head. In such case, it needs to be disassembled. |
