Verification of dimensional characteristics of a transmission

Distances between the case of a transmission and leading shaft, between conducted shaft and an intermediate plate with the ball bearing are checked, and regulated by installation of laying.

Measurement of the sizes of a transmission

The checked sizes:

«A» distance between an interfaced surface of the case of a transmission and leading shaft, the end of the coupling of inclusion of the 5th transfer (the nominal rate makes 141.8 mm.

Distance "In" - between a face surface of the synchronizer of the 4/5th transfers and an interfaced surface of an intermediate case (the nominal rate makes 140.4 mm).

Distance "With" - between an interfaced surface of an intermediate case and an internal holder of the bearing.

The distance of "A" is regulated by laying (43a) a leading shaft.

PERFORMANCE ORDER

1. Press a leading shaft (2) together with the ball bearing (43) in the case of a transmission and establish a lobby to a tap with laying.
2. By means of a calliper measure distance from an interfaced surface of the case of a transmission to a face surface of the coupling. The nominal rate makes 141.8 mm. Determination of thickness of laying: Nominal rate (141.8 mm) - the Measured distance (141.4 mm) = a laying =tolshchina (0.4 mm). Laying in thickness 0.2, 0.3 and 0.9 mm are issued.
3. Carefully establish a leading shaft with the ball bearing in the transmission case.
4. Press laying (shooter) on the ball bearing and press a leading shaft in the transmission case by means of a drift. Check nominal distance.
5. Distance "In" laying (36) in a forward frictional ring (35) kosozuby gear wheels of the 2nd transfer (33).
6. Press the ball bearing (70) in an intermediate case and tighten bolts (69) lock rings (73) to 30 Nanometers.
7. By means of a press plant an intermediate case on a conducted shaft.
8. By means of a calliper measure distance from the synchronizer of the 4/5th transfers to an interfaced surface of an intermediate case. The nominal rate makes 140.4 mm. Determination of thickness of laying: Nominal rate (140.4 mm) - the Measured distance (140.1 mm) = Thickness of laying (0.3 mm). Laying in thickness 0.2, 0.3, 0.5 and 1.4 mm are issued.
9. Remove an intermediate plate from a conducted shaft and adjust a gap laying.
10. The distance "With" is regulated by laying (66) on the ball bearing in an intermediate plate.
11. Fix a conducted shaft with an intermediate plate in a vice and, using a calliper, measure distance from a back surface of an intermediate case to an internal holder of the bearing. Determination of thickness of laying: The measured distance (25.9 mm) - Nominal rate (24.3 mm) = Thickness of laying (1.6 mm). laying in thickness 0.1, 0.3, 0.5 and 1.4 mm.
12. Adjust distance laying, having established them between the ball bearing and a frictional ring. 13. Remove an intermediate case and выпрессуйте the ball bearing of a conducted shaft.
