6-2-9-sborka-korobki-peredach.html 6.2.9. Transmission assemblyTake the rings of the bearings which have remained in nests of parts of a case, and replace all epiploons. Pick up a washer of adjustment of a preliminary tightness of bearings of differential. Establish new rings without a washer of a preliminary tightness.
Establish differential in a case of coupling and connect both parts of a case of a transmission; tighten bolts of fastening the specified moment.
Measure the indicator of hour type an axial gap of differential. Separate parts of a case and take out a ring of the bearing of differential from a transmission case. Establish in a ring nest a washer in thickness on 0,20 — 0,25 mm more than the measured axial moving of differential. Establish into place a bearing ring. Establish primary shaft, a gear wheel of transfer of a backing and its axis with the rasporny plug (fig. 4.39) in a coupling case. Tighten a flange of fastening of the bearing of primary shaft. Establish a secondary shaft. Establish into place a ball and clamp springs, the mechanism of a drive of forks, forks with amortization inserts (fig. 4.40), a rod of forks with a spring (fig. 4.41). Check ease of rotation of shaft. Put a hermetic layer on privalochny surfaces of parts of a case. Connect both parts of a case of a transmission and tighten bolts of fastening the moment of 30 N · m. Uncover, located at an end face of a secondary shaft. Take out an epiploon, then an adjusting ring and the rasporny plug. Measure by means of a nutromer distance (And) between a ring of the bearing and a case surface (fig. 4.42). Pick up the adjusting ring which thickness determine by a formula
T = And + B — In, where And — the measured distance, mm;
B — 0,18 — 0,25 mm; In — 2,5 mm (thickness of the rasporny plug).
Establish into place an adjusting ring (fig. 4.43), having picked up it on tab. 4.3, an epiploon and a cover.
