INSTALLATION
1. Degrease the press-fit section for the chain cover front oil seal, and install the front oil seal to the chain cover using ST.
CAUTION:
Do not apply fluid such as engine oil to the front oil seal and the chain cover; otherwise engine oil leakage may occur.
NOTE:
• Use a new front oil seal.
• When tapping the front oil seal in, protect the radiator fin with cardboards etc. so as not to damage the radiator fin by the plastic hammer.

(4) Draw reference lines (A) and (B) on the crank pulley bolt using a marker as shown in the figure.

(5) Draw end line (C) on crank pulley using a marker at the same position as reference line (B) drawn on the crank pulley bolt in step (3).

(6) Use the ST to lock the crank pulley, and tighten the crank pulley bolt to the angle where reference line (A) and end line (C) are aligned.
NOTE:
It should be approx. 60° when reference line (A) and end line (C) are aligned.
