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
– 0.076
Mm))
Conrod big end oil clearance standard: 0.040 – 0.064 Mm (0.0016 – 0.0025 In)
Conrod big end oil clearance service limit: 0.080 Mm (0.0031 In)
Selection
- Check the corresponding conrod i.D. Code numbers ([1] or [2]) “a”.
Conrod i.D. Specification
- Check the corresponding crank pin o.D. Code numbers ([1], [2] or [3]) “b”.
- Measure the conrod crank pin o.D. With the special tool. If any of the measurements are out of specification, replace the crankshaft.

Use of sds diagnosis reset procedures
Note
the malfunction code is memorized in the
ecm also when the lead wire coupler of any
sensor is disconnected. Therefore, when a
lead wire coupler has been disconnected at
the time of diagnosis, erase the stored
malfunction history code using sds.
