M/T : Manual Transmission A/T : Automatic Transmission COMPRESSION
If the there is lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure.
1. | Warm up and stop engine. Allow the engine to warm up to normal operating temperature.
2. | Remove ignition coils. (See EE group - ignition)
3. | Remove spark plugs. Using a 16mm plug wrench, remove the 4 spark plugs.
4. | Check cylinder compression pressure.
A. | Insert a compression gauge into the spark plug hole.
B. | Fully open the throttle.
C. | While cranking the engine, measure the compression pressure.
Always use a fully charged battery to obtain engine speed of 250 rpm or more.
D. | Repeat steps (a) through (c) for each cylinder.
This measurement must be done in as short a time as possible.
Compression pressure : 1,420kPa (14.5kgf/cm², 206psi) Minimum pressure : 1,270kPa (13kgf/cm², 184psi) Difference between each cylinder : 100kPa (1.0kgf/cm², 15psi) or less
E. | If the cylinder compression in 1 or more cylinders is low, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat steps (a) through (c) for cylinders with low compression.
• | If adding oil helps the compression, it is likely that the piston rings and/or cylinder bore are worn or damaged.
• | If pressure stays low, a valve may be sticking or seating is improper, or there may be leakage past the gasket.
5. | Reinstall spark plugs.
6. | Install ignition coils. (See EE group - ignition)
Timing belt tension adjustment
1. | Remove the engine cover(A).
2. | Remove RH front wheel.
3. | Remove the 4bolts(B) and timing belt upper cover(A).
4. | Turn the crankshaft pulley, and align its groove with timing mark "T" of the timing belt cover.
5. | Temperarily loosen tensioner pulley(A) by center bolt.
6. | Timing belt tension adjusting.
(1) | Rotate crankshaft in regular direction (clock wise view from front) through angle equivalent to two teeth (18°) of camshaft sprocket(A).
(2) | Give tension to timing belt rotating tensioner in arrow direction tool and set timing belt not to give slack to tension side.
(3) | Tightening tensioner bolt.
Tightening torque Tensioner bolt 22.6 ~ 28.4Nm (230 ~ 290kgf.cm, 16.6 ~ 21.0lbf.ft)
(4) | Recheck the belt tension, When the tension side of timing belt is pushed horizontally with a moderate force [approx. 2kg (20N, 5lb)], the timing belt cog end sags in approx. 4 ~ 6mm (0.16 ~ 0.24in.)
7. | Turn the crankshaft two turns in the operating direction (clockwise) and realign crankshaft sprocket and camshaft sprocket timing mark.
8. | Install the timing belt upper cover(A) with 4bolts(B).
Tightening torque 8 ~ 10Nm (80 ~ 100kgf.cm, 6 ~ 7lbf.ft)
9. | Install RH front wheel.
10. | Install engine cover(A).
VALVE CLEARANCE INSPECTION AND ADJUSTMENT MLA (MECHANICAL LASH ADJUSTER)
Inspect and adjust the valve clearance when the engine is cold (Engine coolant temperature : 20°C) and cylinder head is installed on the cylinder block.
1. | Remove the engine cover. (See page EM - 8)
2. | Remove the upper timing belt cover. (See page EM - 9)
A. | Loosen the upper timing cover bolts and then remove the cover.
3. | Remove the cylinder head cover.
A. | Disconnect the spark plug cables and do not pull on the spark plug by force.
Pulling on or bending the cables may damage the connductor inside.
B. | Disconnect the P.C.V hose(A) and the breather hose(B) from the cylinder head cover.
C. | Disconnect the accelerater cable(A) from the cylinder head cover.
D. | Loosen the cylinder head cover bolts(B) and then remove the cover(A) and gasket.
4. | Set No.1 cylinder to TDC/compression.
A. | Turn the crankshaft pulley and align its groove with the timing mark "T" of the lower timing belt cover.
B. | Check that the hole of the camshaft timing pulley(A) is aligned with the timing mark of the bearing cap. If not, turn the crankshaft one revolution (360°)
5. | Inspect the valve clearance.
A. | Check only the valve indicated as shown. [No. 1 cylinder : TDC/Compression] measure the valve clearance. •Using a thickness gauge, measure the clearance between the tappet shim and the base circle of camshaft. •Record the out-of-specification valve clearance measurements. They will be used later to determine the required replaement adjusing shim.

B. | Turn the crankshaft pulley one revolution (360°) and align the groove with timing mark "T" of the lower timing belt cover.
C. | Check only valves indicated as shown. [NO. 4 cylinder : TDC/compression]. Measure the valve clearance. (See procedure in step (6))
6. | Adjust the intake and exhaust valve clearance.
A. | Turn the crankshaft so that the cam lobe of the camshaft on the adjusting valve is upward.
B. | Using the SST(09220-2D000), press down the valve lifter and place the stopper between the camshaft and valve lifter and remove the special tool.
C. | Remove the adjusting shim with a small screw driver(A) and magnet(B).
D. | Measure the thickness of the removed shim using a micrometer.
E. | Calculate the thickness of a new shim so that the valve clearance comes within the specificified value.
