To replace the
Valve Stem Oil Seal and valve spring, remove firstly the valve
Rocker Arm and cover, then the required valve rocker arms and the spark plugs. Attach a shop air supply hose to apply compressed air by holding the valves in the open position using Spark Plug port adapter (J 22794) in the Spark Plug hole. Remove a bolt from valve Rocker Arm, then put a flat washer onto bolt, and then bolt into vazle Rocker Arm bolt hole for vazle spring to be removed from. Take care with compressed valve springs, as they have high tension. The valve spring compressor (J 5892-D) will compress the valve spring using its slotted end that hooks under the washer on the valve Rocker Arm bolt and steady pressure until the valve keys are accessible. Safe enough, make use of valve spring compressor (J 38606) if required in order to achieve a total engagement on to the valve spring. Take off the valve keys, gently relieve the valve spring tension, and then get rid of the compressor tools. Then, take out the valve spring cap and valve spring with Valve Stem Oil Seal. Mount the valve into the correct valve guide, identify the correct Valve Stem Oil Seal, and apply the oil to the valve guide as well as the Valve Stem Oil Seal. Mount the Valve Stem Oil Seal unto the valve guide using valve stem seal installer (J42073) ensuring of a space of 1 - 2mm between the seal and the guide. Put back the valve spring and valve spring cap and re-compress the valve spring using valve spring compressor (J 5892-D) or (J 38606) if necessary. In order to install the valve stem o-ring seal and valve stem keys, grease should be used to secure the keys. Gradually reduce the valve spring pressure as long as the keys are seated and remove the compressor tools. Finally, ensure the valve stem keys are installed, and either tap the valve stem or remove Spark Plug port adapter (J 22794), and then install the spark plugs, valve rocker arms, and valve Rocker Arm cover.
