REPAIR PROCEDURE
1. Remove the right front wheel.

6. Turn the crankshaft counterclockwise to line up the holes on the lock and the cam chain auto-tensioner, then insert a
1.2 mm (3/64 in)-diameter pin into the holes. Turn the crankshaft clockwise about 90 degrees to secure the pin.
Remove the cam chain auto-tensioner, and be careful not to drop the bolts into the timing case.
NOTE
If the holes in the lock and the cam chain auto-tensioner do not line up, keep turning the crankshaft
counterclockwise until they do, then install the pin.

7. Remove the cam chain auto-tensioner filter and inspect for damage.
•

If the filter is not damaged, clean it with brake cleaner. Do not use a fabric or shop towel to clean the filter. This
will leave lint and foreign particles in the filter screen.

•

If the filter is damaged, install a new filter onto the new cam chain auto-tensioner.

8. Install the new cam chain auto-tensioner with filter, and torque the bolts to 12 N∙m (9 lb-ft). Then, remove the pin.

9. Make sure the case cover mating surfaces are dry. Apply liquid gasket (HondaBond 4) to the chain case cover
mating surfaces and to the inside edge of the threaded bolt holes as shown.

10. Install the component within 5 minutes of applying the liquid gasket, and torque the bolts to 12 N∙m (9 lb-ft).
11. Install the engine splash shield or undercover.
12. Install the right front wheel and torque the nuts to 108 N∙m (80 lb-ft).
13. Top off the engine oil level.
14. Start the engine, warm up to operating temperature, and check for leaks.
