|2.||Measure the clearance between 2nd gear (C) and 3rd gear (D) with a feeler gauge (E).|
|3.||Measure the thickness of 3rd gear.|
|4.||Measure the clearance between 4th gear (A) and the distance collar (B) with a dial indicator (C).|
|5.||Measure distance (1) on the distance collar.|
|6.||Measure the thickness of 4th gear.|
|7.||Measure the clearance between the distance collar (A) and 5th gear (B) with a dial indicator (C). If the clearance is more than the service limit, go to 8. If the clearance is within the service limit, go to 10.|
|8.||Measure distance (2) on the distance collar.|
|9.||Measure the thickness of 5th gear.|
|10.||Measure the thickness of the MBS distance collar.|
