Dimensions biscuit lock mm
| Element | 1 | 2 | 3 | | 1st / 2nd | 19.0 | 4.25 | 50 | | 3rd / 4th | 17.0 | 4.25 | 50 | | 5th / ZH | 17.0 | 4.25 | 50 |
| PERFORMANCE ORDER |  | Place crackers and spring retainer into the sleeve of the synchronizer hub. |

Bearing (by differential)
| PERFORMANCE ORDER |  | Using a press and special adaptation OK900 175 AA1, establish a new bearing. |
|
Gear of 1st transfer, a ring of the synchronizer of 1st transfer and the synchronizer of 1st / 2nd gear
Synchronizer ring 2nd transfers and a gear wheel 2nd transfers and a conducted gear wheel of 3 transfers
| PERFORMANCE ORDER | | 1. Establish a synchronizer ring 2nd transfers and a gear wheel 2nd transfers. |  | 2. Using a press and special adaptation OK900 175 AA1, establish a gear wheel of 3 transfers. |
|
Driven gear 4th transfer and the bearing inner ring
| PERFORMANCE ORDER |  | 1. Using a press and special adaptation OK900 175 AA1, establish a gear wheel of 4th transfer and the bearing inner ring. |  | 2. Measure the clearance between the first gear transmission and drive gear differential. Nominal backlash: 0,05-0,28 mm
Maximum permissible backlash: 0,33 mm | | 3. Measure the clearance between the gear 2nd gear driven gear and third gear. Nominal backlash: 0,18-0,45 mm
Maximum permissible backlash: 0,51 mm |  | 4. If backlashes do not correspond demanded, disassemble and reassemble the secondary shaft. |
