necessary, crankshaft may only be turned slightly for adjustment
and blocked at flywheel ring gear.
——Engage timing belt tooth with crankshaft grooves，and pull

2 tension pulley mounting bolts and loosen crankshaft locking
device.
——Rotate crankshaft clockwise (viewed from the pulley end) 2
turns until no.1 cylinder reaches its TDC of compression.
