8 - hub coupling the 1st and 2nd gear assembly;
9 - a ring of the synchronizer of 1st transfer; | 10 - a gear wheel of 1st transfer;
11 - Bearing (secondary shaft end);
12 - a secondary shaft;
13 - a spring latch biscuit synchronizer;
14 - a nave of the synchronizer clutch backing;
15 - biscuit lock synchronizer;

Preliminary checks Axial backlash gear 1st gear
| PERFORMANCE ORDER |  | 1. 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 | | 2. If the clearance exceeds the limit, check the contact surface of the first gear transmission pinion differential and the clutch hub synchronizer of 1st / 2nd gear. Replace worn or damaged parts.

|
Axial backlash gear 2nd gear
| PERFORMANCE ORDER |  | 1. Measure the clearance between the gear 2nd gear driven gear and third gear. Nominal backlash: 0,18-0,46 mm
Maximum permissible backlash: 0,51 mm | | 2. If the clearance exceeds the limit, check the contact surface of the gear 2nd gear, driven gear 3rd gear and the clutch hub synchronizer of 1st / 2nd gear. Replace worn or damaged parts.
