Suzuki GSX-R 1000 Service Manual: Conrod crank pin bearing inspection and selection
Refer to “engine bottom side disassembly” (page 1d- 49).
Refer to “engine bottom side assembly” .
Inspection
- Inspect the bearing surfaces for any signs of fusion, pitting, burn or flaws. If any, replace them with a specified set of bearings.
- Place the plastigauge axially along the crank pin, avoiding the oil hole, as shown in the figure.
Special tool
(a): 09900–22301 (plastigage (0.025
– 0.076
Mm))
- Tighten the conrod cap bolts to the specified torque, in two stages.
Note
|
Tightening torque conrod cap bolt: 37 n·m (3.7 Kgf-m, 26.5 Ib-ft) then turn in 1/6 (60°) turn
- Remove the conrod cap bolts and measure the width
of the compressed plastigauge using the envelope
scale. This measurement should be taken at the
widest part of the compressed plastigauge.
If the oil clearance exceeds the service limit, select the specified bearings from the bearing selection table.
Special tool
(a): 09900–22301 (plastigage (0.025
