Suzuki GSX-R 1000 Service Manual: Crankshaft thrust clearance inspection and selection

Refer to “engine bottom side disassembly” (page 1d- 49).

Refer to “engine bottom side assembly” .

Inspection

1. With the crankshaft’s right-side and left-side thrust bearings inserted into the upper crankcase.
2.  Measure the thrust clearance “a” between the leftside thrust bearing and crankshaft using the thickness gauge. If the thrust clearance exceeds the standard range, adjust the thrust clearance.

Special tool : 09900–20803 (thickness gauge)

Crankshaft thrust clearance “a” standard: 0.060 – 0.110 Mm (0.0024 – 0.0043 In)

Selection

1. Remove the right-side thrust bearing and measure its thickness using the micrometer. If the thickness of the right-side thrust bearing is below standard, replace it with a new bearing and measure the thrust clearance again, as described in inspection 1) and 2).

Special tool (a): 09900–20205 (micrometer (0 – 25
mm))

Right-side thrust bearing thickness standard: 2.420 – 2.440 Mm (0.0953 – 0.0961 In)

2. If the right-side thrust bearing is within the standard range, reinsert the right-side thrust bearing and remove the left-side thrust bearing.
3.  With the left-side thrust bearing removed, measure the clearance “a” using the thickness gauge as shown.

Special tool (b): 09900–20803 (thickness gauge)

1. Select a left-side thrust bearing from the selection table.

5. After selecting a left-side thrust bearing, install it and then measure the thrust clearance again.
