Honda HR-V: Camshaft Inspection

Inspection

1. Rocker Arm Assembly - Remove

2. Rocker Arm Assembly - Disassemble

3. Camshaft Sprocket - Remove

4. Camshaft End Play - Inspect

Fig. 1: Lost Motion Holder Tightening Sequence With Torque Specifications

1. Put the rocker shaft holders and the lost motion holder on the cylinder head
2. Tighten each bolts two turns at a time in sequence
3. Seat the camshaft by pushing it toward the camshaft pulley end of the cylinder head.

4. Zero the dial indicator against the end of the camshaft. Push the camshaft back and forth, and read the end play. If the end play is beyond the service limit, replace the thrust cover and recheck. If it is still beyond the service limit, replace the cylinder head. If it is still beyond the service limit, replace the camshaft.

Standard (New): 0.05-0.25 mm (0.0020-0.0098 in)
Service Limit: 0.4 mm (0.016 in)

5. Camshaft - Remove

6. Camshaft - Inspect

1. Wipe the camshaft clean, then inspect the lift ramps. Replace the camshaft if any lobes are pitted, scored, or excessively worn
2. Measure the diameter of each camshaft journal.

3. Zero the dial indicator to the journal diameter.

4. Clean the camshaft bearing surfaces in the cylinder head. Measure the inside diameter of each camshaft bearing surface, and check for an out-of-round condition:
   • If the camshaft-to-holder clearance is within limits, go to step 6.
   • If the camshaft-to-holder clearance is beyond the service limit and the camshaft has been replaced, replace the cylinder head.
   • If the camshaft-to-holder clearance is beyond the service limit and the camshaft has not been replaced, go to step 5.

Standard (New): 0.045-0.084 mm (0.00177-0.00331 in)
Service Limit: 0.15 mm (0.0059 in)

5. Check the total runout with the camshaft supported on V-blocks:
   • If the total runout of the camshaft is within the standard, replace the cylinder head.
   • If the total runout is beyond the standard, replace the camshaft and recheck the camshaft-to-holder oil clearance. If the oil clearance is still out of standard, replace the cylinder head.

Standard (New): 0.03 mm (0.0012 in) max.

6. Measure the cam lobe height.

7. All Removed Parts - Install

1. Install the parts in the reverse order of removal.

CAMSHAFT TIMING INSPECTION

Inspection

1. Cylinder Head Cover - Remove

2. Camshaft Timing - Inspect

1. Turn the crankshaft so its white mark (A) on the crankshaft pulley lines up with the pointer (B).

2. Check the No. 1 piston at top dead center (TDC). The "UP" mark (A) on the camshaft sprocket should be at the top, and the TDC grooves (B) on the camshaft sprocket should aline up with the top edge of the cylinder head.
   NOTE:
   • If the marks are not aligned, rotate the crankshaft 360 degrees, and recheck the camshaft pulley mark.
   • If the marks still do not align, remove the cam chain and reinstall the cam chain properly.

3. All Removed Parts - Install

1. Install the parts in the reverse order of removal.
