Adjustment of an axial gap of a persistent disk of a brake (Brake reaction plate end play)

Fig. 3.60. Scheme of adjustment of an axial gap of a persistent disk of a brake


Replace press a disk (pressure plate) of a brake of the first transfer and transfer of a backing with special adaptation and then establish a disk with slips (brake disk), a disk without slips (brake plate) and a lock ring, as shown in the figure 3.60. Establish a persistent disk and the removed earlier original lock ring. Moving special adaptation, measure an axial gap and then if the axial gap does not correspond to nominal rate, adjust it, having replaced an original lock ring new the corresponding thickness.
Nominal rate: 0,0–0,16 mm
(You watch help table 3.16).

Adjustment of an axial gap of a brake of the second transfer (Second brake end play)

Fig. 3.61. Scheme of adjustment of an axial gap of a brake of the second transfer


Replace press a disk (pressure plate) of a brake of the second transfer with special adaptation and then establish a disk with slips (brake disk), a disk without slips (brake plate), as shown in the figure 3.61. Establish a returnable spring (return spring), the piston of a brake of the second transfer (second brake piston) and a lock ring.
Nominal rate: 0,79–1,25 mm.
If the axial gap does not correspond to nominal rate, then adjust it, having picked up new press a disk which thickness corresponds to the specified range of values.

Fig. 3.62. Axial gap of a brake of the second transfer


Thickness of a new press disk = (the measured gap "And") + (thickness of special adaptation) – (nominal rate of an axial gap) (fig. 3.62).
You watch help table 3.16.

Adjustment of an axial gap of a brake of the first transfer and transfer of a backing

Fig. 3.63. Measurement of an axial gap of a brake of the first transfer


Turn the transmission a back part up and install the indicator of the sentry like (fig. 3.63).
Moving special adaptation up and down, measure an axial gap.
Nominal rate: 1,35–1,81 mm.
If the axial gap does not correspond to nominal rate, then adjust it, having picked up new press a disk which thickness corresponds to the specified range of values.

Fig. 3.64. Axial gap of a brake of the first transfer


Thickness of a new press disk = (the measured gap "And") + (thickness of special adaptation) – (nominal rate of an axial gap) (fig. 3.64).
You watch help table 3.15.

Adjustment of an axial gap of a solar gear wheel of the lowering planetary row (underdrive sun gear end play)

Fig. 3.66. Measurement of an axial gap of a solar gear wheel of the lowering planetary row


Establish the removed earlier original holder of the persistent bearing No. 8, then establish a back cover of a case of the check point. Measure an axial gap of a solar gear wheel of the lowering planetary row (fig. 3.66).
If the axial gap does not correspond to nominal rate, then adjust it, having picked up for the provided table a new holder of the persistent bearing #8 the corresponding thickness.
Nominal rate: 0,25–0,45 mm.

NOTE
For simplification of measurements of an axial gap of a solar gear wheel of the lowering planetary row establish a nave of the coupling of the lowering transfer.

Adjustment of a preliminary tightness of the case of differential (Differential case preload)
Put a piece of soft solder (length about 10 mm and with a diameter about 3 mm) on a hydrotransformer case.

Fig. 3.67. Solder extraction


Establish a hydrotransformer case on a check point case without sealant use. Tighten fastening bolts the nominal moment. Weaken bolts of fastening and extract solder (fig. 3.67).

Fig. 3.68. Measurement of thickness of the deformed piece of solder


By means of a micrometer measure thickness of "T" of the deformed piece of solder. For creation of a nominal preliminary tightness pick up a pro-rate which thickness corresponds to the specified range of values (fig. 3.68).
Nominal rate: 0,045–0,105 mm.
Pro-rate thickness = (thickness of solder "T") + (nominal rate of a preliminary tightness)
