ALL ALUMINUM SLIDE CAM-PULLEY Scale adjustment, improved visibility, durability and strength. All factors have been improved.

Easy and precise valve timing adjustment

Valve timing is adjustable for ±20° of crankshaft angle if two bolts that fix pulley and plate are loosen. Vernier scale enables small adjustment of valve timing.. If valve timing is changed, engine characteristic is changed for specification of camshaft or characteristic of boost. This is effective even for stock camshaft.

Strength of timing belt is optimized for each vehicle. Even expansion of engine by heat is considered to stabilize tension of timing belt.
	With usual production technology, teeth portion is shaped by pressing from outside. With this production, fabric of teeth is pulled and the tension will reduce strength. Thus, with the new production technology, fabric of teeth is  aligned to metal mold of teeth and teeth rubber is filled in the fabric to keep strength of the teeth fabric that can accept high torque.
	High density H-NBR is used for teeth rubber to strengthen teeth portion.
