7-2 Disintegration of crankshaft connecting rod 
mechanism 
1、Check the connecting rod axial clearance 

(1) Use centi-meter or feeler to measure axial 

spacing 

[Benchmark]:0.15-0.24mm 
[Limit]:0.30mm 

 

 

2、Check the connecting rod bush vertical clearance 

(2)Remove the bush cover 

[Attention]: Parts and components of various 
cylinders should be placed in good order. 
(1) Clean the bush and axle diameter 

 
 
 

 

  (4) Place clearance gauge on the connecting bearing 
diameter. 

 

 
(5) Tighten bush cover according to regulated torque 

torque: 40±2N.m                             

 

 

[Attention] Do not turn the crankshaft 
(6) Remove the bush cover, measure the maximum 
width of the spacing ruler 

[Benchmark]: 0.020-0.044 mm 
[Limit]: 0.07 mm

(6) Replace the bush if width is beyond the limit. 
[Attention]: 
·In replacing the bushes, you should use the products 
of same brand and from the same manufacturer,which 
can accord with the request of clearings. 
3. Removal of connecting rod bearing cover and 
connecting rod bush 

 

(1)  The threaded section of the connecting rod bolt is 
to be equipped with protective sleeve to prevent from 
scraping the cylinder hoe and crankshaft connecting 
rod axle diameter. Then knock the piston connecting 
rod out with the handle of a hammer. 
[Attention] Put the parts and components of various 
cylinders in good order. 
 

(2) Use a caliper to measure the crankshaft axial 
clearance. If the axial clearance is above the limits, it 
is needed to replace the axial thrust washer or the 
crankshaft. 
[Benchmark]:0.02-0.22mm 
[Limit]:0.30mm
