If needed, align the strain piston earlier than tensioning, utilizing needle-nosed pliers or a skinny wire (the opening in strain piston and gap in housing should overlap). Tighten the stress piston solely far sufficient in order that the stress piston will be secured utilizing a T40001 pin.
Insert a V.A.G 1331 hex torque wrench into the hex socket, and torque the tensioning curler nut in counter-clockwise course with uniform non-extreme drive till the toothed belt might be aligned with the mark on the cylinder block. Use the T10008 locking plate to lock in place the curler. To loosen toothed belt, loosen the nut of the tensioning curler by turning the wrench within the clockwise course.

Rotate the crankshaft till the primary cylinder is within the top dead center (TDC) place. Set up the timing belt within the particular order. First, place the belt on the coolant pump, after which on the tensioning curler and, lastly, on the camshaft gear.
Rigidity the timing belt by pulling out the T40001 pin and unbolting the T10092 tensioning bolt. The engine should not be greater than hand heat. If the timing belt tensioning system is totally prolonged, it should be pressed again within the put in place with the tensioning curler. This process can take as much as 5 minutes. Extreme power throughout compression can injury the tensioning curler.
Flip the 3387-pin wrench in counter-clockwise path till the T10008 locking plate will be eliminated with out pressure. Flip the pin wrench clockwise till a drill bit might be pulled via the tensioning lever and the housing of the tensioning system. Maintain the tensioning curler on this place and tighten the securing nut of the tensioning curler, as you apply 20 foot-kilos of torque. Flip the crankshaft two rotations and examine whether or not the camshaft and crankshaft marks align with their reference factors.
