Kawasaki WORKHORSE 250 (2003) [153/322] Connecting rod big end radial clearance

CRANKSHAFT/TRANSMISSION 9-13

Crankshaft/Balancer Shaft and Connection Rod

Connecting Rod Big End Radial Clearance

•

Set the crankshaft on V blocks, and place a dial gauge [A]

against the connecting rod big end.

•

Push [B] the connecting rod first towards the gauge and

then in the opposite direction. The difference between the

two gauge readings is the radial clearance.

If the radial clearance exceeds the service limit, the crank-

shaft assembly must be replaced or disassembled and

the c rankpin, needle bearing, and connecting rod big end

examined or wear.

Connecting Rod Big End Radial Clearance

Standard: 0.008 ∼ 0.020 mm (0.0003 ∼ 0.0008 in.)

Service L imit: 0.07 mm (0.003 in.)

Connecting Rod Big End Side Clearance

•

Set the crankshaft on V blocks.

•

Measure the side clearance [A] of the connecting rod with

a thickness gauge.

If the big end side clearance exceeds the service limit, the

crankshaft assembly must be replaced or disassembled

and the connecting rod visually inspected for wear.

Connecting Rod Big End Side Clearance

Standard: 0.4 ∼ 0.5 mm (0.016 ∼ 0.020 in.)

Service L imit: 0.7 mm (0 .028 in.)
