.2) Detecting the crankshaft; if there is a crack; it is necessary to replace it. Look carefully at the crankshaft main journal, the connecting rod journal and its transition circle. The slanting smashing 糜 糜 邸 邸 (5) 撕 龊 龊.
.3) Look at the crankshaft main journal and the connecting rod journal; after the scale exceeds the limit, the correction is corrected according to the correction level. The crankshaft journal correction is as follows:
.4) Check the hardness requirements of the crankshaft journal and the connecting rod journal; it is necessary to meet the skill requirements. Otherwise, it should be re-disposed; to satisfy the demand.
.5) The radial runout of the crankshaft and the thrust of the crankshaft face the radial runout of the common axis of the main journal; it is necessary to meet the skill requirements. Otherwise; it is necessary to proofread.
.6) The axis of the connecting rod journal; it is necessary to meet the skill requirements for the parallelism of the common axis of the main journal in the whole length.
.7) When the front and rear transmission gears of the crankshaft have cracks, damage and severe wear; the crankshaft should be replaced.
.8) If there is a crack in the crankshaft balance block bolt, it is necessary to replace it. After the crankshaft replaces the balance block or the balance block bolt; the dynamic balance experiment is performed on the crankshaft assembly; the unbalance amount is guaranteed to meet the skill requirement.
.9) If the flywheel and pulley bolts are cracked, scratched or stretched beyond the limit; replace them.
.10) Carefully look at the shock absorber of the crankcase feet; if damaged, rubberized, cracked, deformed or cracked; it is necessary to replace.
.11) When installing the crankshaft; pay attention to the bearing of the main bearing bush and thrust tile. Check the axial clearance of the crankshaft and tighten the straight bolts and horizontal bolts of the main bearing cap as required. (First straight; rear horizontal)
