Honda HR-V: Cylinder Bore Honing
Honing
1. Oil Jet - Remove
2. Cylinder Bore - Honing
- Measure the cylinder bores. If the engine block is to be reused, hone
the
cylinders and remeasure the bores. Only scored or scratched cylinder bore
must be
honed.
- Hone the cylinder bores with honing oil and a fine (400 grit) stone.
Honing Pattern: Within 30-60 degree cross-hatch pattern (A)
NOTE:
- Use only a rigid hone with 400 grit or finer stone such as Sunnen, Ammco,
or equivalent.
- Do not use stones that are worn or broken.
- When honing is complete, thoroughly clean the engine block of all metal
particles. Wash the cylinder
bores with hot soapy water, then dry and oil them immediately to prevent
rusting.
NOTE : Never use solvent, it will only redistribute the grit on the
cylinder walls
- If scoring or scratches are still present in the cylinder bores after
honing to the service limit, rebore the
engine block. Some light vertical scoring and scratching is acceptable if it
is not deep enough to catch
your fingernail and does not run the full length of the bore.
3. All Removed Parts - Install
- Install the parts in the reverse order of removal.
ENGINE COMPRESSION INSPECTION
Inspection
NOTE: After this inspection, you must reset the PCM. Otherwise, the PCM will
continue to stop the injectors
from operating.
1. Engine - Warm Up
- Start the engine. Hold the engine speed at 3, 000 rpm with no load (M/T
in neutral, CVT in P or N)
until the radiator fan comes on, then let it idle.
2. HDS DLC - Connect
NOTE: For specific operations, refer to the user's manual that came with the
HDS. Make sure the
HDS is loaded with the latest software.
- Turn the vehicle to the OFF (LOCK) mode.
- Connect the HDS to the DLC.
- Turn the vehicle to the ON mode.
- Make sure the HDS communicates with the vehicle. If it does not
communicate, go to the DLC circuit troubleshooting.
3. ALL INJECTORS STOP - Select
- Select ALL INJECTORS STOP in the PGM-FI INSPECTION menu with the HDS
- Turn the vehicle to the OFF (LOCK) mode.
4. Ignition Coil and Spark Plug - Remove
5. Engine Compression - Inspect
- Attach a compression gauge to the spark plug hole
- Step on the accelerator pedal to open the throttle fully, then crank the
engine with the starter motor, and measure the compression.
Above 880 kPa (8.97 kgf/cm2, 127.6 psi)
- Measure the compression on the remaining cylinders.
Maximum Variation
Within 200 kPa (2.04 kgf/cm2, 29.0 psi)
- If the compression is out of specifications, perform a cylinder leak
down test to determine the problem
area. Then check the following items, and remeasure the compression:
- Incorrect valve clearance
- Confirmation of camshaft timing
- Damaged or worn cam lobes
- Damaged or worn valves and seats
- Damaged cylinder head gasket
- Damaged or worn piston rings
- Damaged or worn piston and cylinder bore
- Remove the compression gauge from the spark plug hole.
6. Ignition Coil and Spark Plug - Install
7. ALL INJECTOR STOP - Select
- Select PCM reset in the PGM-FI system to cancel ALL INJECTORS STOP with
the HDS.
ENGINE OIL JET AND BOLT INSPECTION
Inspection
1. Oil Jet and Oil Jet Bolt - Remove
2. Engine Oil Jet and Oil Jet Bolt - Inspect
- Inspect the oil jet and the oil jet bolt as follows:
- Make sure that a 1.0 mm (1/32 in) diameter drill bit will go through
the nozzle
hole (A) (1.2 mm (0.047 in) diameter).
- Insert the other end of a 0.8 mm (1/32 in) drill bit into the oil
intake (1.0 mm
(0.039 in) diameter). Make sure the check ball (B) moves smoothly and
has a
stroke of about 4.0 mm (0.157 in).
- Check the oil jet bolt operation with an air nozzle. It should take
at least 310
kPa (3.16 kgf/cm2, 45.0 psi) to unseat the check ball.
3. All Removed Parts - Install
- Install the parts in the reverse order of removal.
