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.

Special tool
(a): 09900–20202 (micrometer (25 –
50
mm))
- Select the specified bearings from the bearing selection table.
| Caution the bearings should be replaced as a set. |

Break-in procedures
During manufacture only the best possible materials are
used and all machined parts are finished to a very high
standard but it is still necessary to allow the moving parts
to “break-in” before subjecting the engine to maximum
stresses. The future performance and reliability of the
engine depen ...
Generator inspection
Generator coil resistance
Remove the left side cowling. Refer to “exterior parts removal and
installation” in section 9d .
Disconnect the generator coupler (1).
Measure the resistance between the three lead
wires.
If the resistance is out of specified value, replace the
