Before dismantling the input shaft, the following measurements should be made. If any dimensions are out of tolerance, then the input shaft should be disassembled and the non-compliant parts replaced.
If all dimensions meet the tolerances, then the input shaft should be disassembled only in case of mechanical damage to any of its parts.
1. Pull down the bearing race with the clutch and measure the clearance between the 2nd and 3rd gears. The tolerance is 0.06-0.3 mm. If the tolerance is not met, then the input shaft should be disassembled and the 3rd gear gear should be inspected.
2. Measure a backlash between a gear wheel of 4th transfer and cuffs laying. The tolerance is 0.06-0.3 mm. If the tolerance is not met, then the input shaft should be disassembled and the 4th gear gear and the gasket seal should be inspected.
3. Measure a backlash between a gear wheel of 5th transfer and cuffs - lining. The tolerance is 0.06-0.3 mm. If the tolerance is not met, then the input shaft should be disassembled and the 5th gear gear and the gasket seal should be inspected.
