note

●

Thoroughly clean all parts to be assembled.

●

Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.

Install the valves.

(1)

Using the SST (09222-03100), push in a new valve stem seal.

note

●

Do not reuse old valve stem seals.

●

Incorrect installation of the seal could result in oil leakage past the valve guides.

(2)

Install the valve, valve spring and spring retainer.

note

Place valve springs so that the cone shape side is upward retainer side.

(3)

Using the SST (09222-3K000, 09222-3K100), compress the spring and install the retainer locks. After installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring compressor.

(4)

Lightly tap the end of each valve stem two or three times with the wooden handle of a hammer to ensure proper seating of the valve and retainer lock.

Install the swing arm and the hydraulic lash adjuster assembly (A).

(1)

Until installing HLA shall be held upright so that engine oil in HLA should not spill and assured that dust does not adhere to HLA.

(2)

HLA shall be inserted tenderly to the cylinder head not to spill engine oil from HLA. In case of spilling, air vent shall be done in accordance with the air bent procedure.

note

Stroke HLA in engine oil 4~5 times by pushing its cap while pushing the ball down slightly by hard steel wire.

(Take care not to severely push hard steel wire down since ball is several grams.)

note

After installed on engine, lash adjuster might give out unusual noise. If air is mingled then apply slow racing (Approx. one minute for 1 racing) from idle to 3000rpm and is removed from adjuster.
