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
- Put the rocker shaft holders and the lost motion holder on the cylinder
head
- Tighten each bolts two turns at a time in sequence
- Seat the camshaft by pushing it toward the camshaft pulley end of the
cylinder head.
- 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
- Wipe the camshaft clean, then inspect the lift ramps. Replace the
camshaft
if any lobes are pitted, scored, or excessively worn
- Measure the diameter of each camshaft journal.
- Zero the dial indicator to the journal diameter.
- 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)
- 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.
- Measure the cam lobe height.
7. All Removed Parts - Install
- Install the parts in the reverse order of removal.
CAMSHAFT TIMING INSPECTION
Inspection
1. Cylinder Head Cover - Remove
2. Camshaft Timing - Inspect
- Turn the crankshaft so its white mark (A) on the crankshaft pulley
lines up with the pointer (B).
- 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
- Install the parts in the reverse order of removal.
