Honda Accord: Cam Chain Inspection

Special Tools Required

Cam Chain inspection Gauge 07AAJ-RWCA100

1. Remove the front wheels.

2. Remove the splash shield (see step 25 on page 5-5).

3. Remove the cylinder head cover (see page 6-73).

4. Rotate the crankshaft pulley two turns clockwise.

5. Set the No. 1 piston at top dead center (TDC). The punch mark (A) on the variable valve timing control (VTC) actuator and the punch mark (B) on the exhaust camshaft sprocket should be at the top. Align the TDC marks (C) on the VTC actuator and the exhaust camshaft sprocket.

6. Measure the clearance between the cam chain (A) and the tensioner arm (B) with the cam chain inspection gauge (07AAJ-RWCA100).

- If the clearance is OK, go to step 17.

- If the clearance is more than the service limit, go to step 7.

Chain-to-Arm Clearance

Service Limit:

MIL on with P0341:        4.3 mm (0.17 in)

Without MIL: 5.5 mm (0.22 in)

7. Remove the oil pan (see page 7-11).

8. Support the engine with a jack and a wood block under the engine block.

NOTE: Do not hit the oil pump and the baffle plate when placing the jack on the edge of the engine block.

9. Remove the cam chain (see page 6-62), and check the teeth on the crankshaft sprocket, the VTC actuator, and the exhaust camshaft sprocket for wear and damage. If any of them are worn or damaged, replace if necessary.

10. Check the oil passage on the auto-tensioner for clogs.

If the auto-tensioner is clogged, replace it.

11. Measure the length of the oil pump chain auto-tensioner rod.

Oil Pump Chain Auto-Tensioner Rod Length

Service Limit: 13 mm (0.51 in)

12. If the length is over the service limit, replace the oil pump chain (see page 8-25). When replacing, check the teeth on the crankshaft sprocket and the oil pump sprocket for wear and damage, if any of them are worn or damaged, replace if necessary.

13. Check the oil passage on the oil pump chain auto-tensioner for clogs. If the auto-tensioner is clogged, replace it.

14. Install the new cam chain (see page 6-64).

15. Remove the jack and the wood block.

16. Install the oil pan (see page 7-30).
