The top clearance between the journal and a new bearing shell is the
result of a summation of the production tolerances of the bearing
ponents .
轴颈与轴瓦的顶部间隙是轴承装配成分产生的公差的总和.
The top clearance for a new bearing will normally be in the range stated
In Data .Note that the figures are to be used for guidance only .
一个新轴承的顶部间隙通常在数据规定的列表中记录那个数值仅做为指导.
For the top clearance of a specific bearing ,see the measurement in
the Adjustment Sheet in Volume I ,OPERATION .
对于特殊轴承的顶部间隙看操作卷1中调节垫片的测量法.
1. Open the crankcase door at the relevant cylinder .
打开相应缸的曲拐箱道门.
2. Turn the crankthrow concerned to BDC .
把有关的曲柄臂盘到下止点.
3. Measure the clearance in the crosshead bearing by inserting a feeler gauge
Between the bearing cap and the crosshead journal at the top of the
upper bearing shell .See Data .
在上轴承顶部,轴承盖与十字头轴颈间插入塞尺测量十字头的轴承间隙.
4. The difference between the actual clearance measurement and the
measurement recorded in the Adjustment Sheet (or the clearance noted for
a new bearing installed later) must not exceed .If so ,the crosshead bearing must be disassembled for inspection .See Procedure 904- .
