, then use 3# open-end wrench to adjust the screw
⑸
, use a feeler
gauge to measure the valve clearance, after adjusting to the corresponding clearance range, 3# open-end wrench
to fix the screw
⑸
, 8# torx wrench lock Tighten the nut
⑷
, tighten the torque to 9±1N.m, and finally measure
the gap again.
Intake valve clearance: 0.12±0.02mm, two intake valve clearance difference
≤
0.02mm, exhaust valve
clearance: 0.20±0.02mm, two exhaust valve clearance difference
≤
0.02.
CAUTION:
