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
