- 1). Check the condition of the gears and shafts of the gearbox, the presence of cracks and other damage
- 2). Check the end clearance of the gears and compare with the standard.
- 3). If damage is observed and the play exceeds the norm, then completely disassemble the gearbox and replace the worn parts
- 4). Press off the front bearing of the intermediate shaft with a puller.
- 5). Remove the retaining ring.
