A WARNING To carry out adjustments transmission and differential Special tools. Never attempt to make an adjustment without special tools and fixtures. |
Adjusting the primary shaft of a transmission of type 085. A primary shaft of a transmission of type 085 is not required to adjust, but you need to see to it to remove the shim when dismantling the assembly has been re-established. Nevertheless, the axial play of the primary shaft measured by comparing the device should be in the range of 0.01 to 0.12 mm. To achieve this magnitude are applied shims of different thicknesses. The values of relative input shaft endplay measured by the comparator and the corresponding thicknesses of shims shown in Table. 5.4. Adjusting the secondary shaft of a transmission of type 085. Adjusting the output shaft is to determine the thickness of the shim located under foreign yoke front bearing shaft. This is - the smaller of the two tapered roller bearings. Determine the thickness of the shim a special device in the following sequence: - Insert the shim thickness of 0.75 mm in the socket casing and press in the clutch outer race of the bearing smaller; - Insert the output shaft and the transmission housing Dock with the clutch housing; - Tighten the gearbox to 25 Nm;
| Fig. 5.45. Measure axial play of the secondary shaft of a transmission of type 085 1 - mandrel
|
- Establish a special device with dial gauge (Fig. 5.45) on the transmission housing and secure with universal dial gauge holder to the support legs of the mandrel 1. The indicator set on the supporting mandrel with preload of 1 mm, and in this position lock indicator then the arrow indicator set to zero; - Move from the bottom up and down the shaft and follow the indications of the indicator, which may be about 0.30 mm;
A WARNING When measuring the axial movement of the shaft does not rotate it so as not to distort the measurement results. |
- According to the formula S = A + B + C, calculate the thickness of the shim bearing front where S - thickness of the shim, mm; A - the axial displacement of the shaft (measured value), mm; In - the value of preload mm; S - thickness of shims (a constant value) mm. Example of measurement is as follows.
NOTE The magnitude of preload bearing shaft of 1 mm, according to the instructions obtained when added to the measured value of 0.20 mm. |
Let the thickness of shims C = 0.75 mm, the measured value of A = 0.30 mm, the amount of preload B = 0.20 mm. Consequently, the thickness of shim S = 0,75 + 0,30 + 0,20 = 1,25 mm; - After determining the thickness of the shim remove the gearbox housing, remove the secondary shaft and remove the outer ring of the bearing from the clutch housing. Put shim thickness equal to resulting value. Fit the bearing race, set the output shaft and the transmission housing. To adjust the tightness of the bearing of a secondary shaft provided shims of different thickness (total of 16 sizes from 0,650 to 1,400 mm and a pitch of 0.05 mm), presented in the Table. 5.5.

Measuring the modulus couples rotation output shaft bearing is carried out using a dynamometer 2 (Fig. 5.46). For new lubricated bearings the moment of resistance must be equal to 0.8 to 1.6 Nm, and the bearing of used - at least 0.3 Nm. Adjusting the differential transmission of type 085 differential bearings should be mounted with preload 0.40 mm. Preload is provided by the selection of the thickness of the shim installed in the nest the gearbox under the outer ring of the bearing of differential. Determine the thickness of the shim a special device in the following sequence: - Press in the outer ring of the bearing of differential towards the crown wheel by placing a clip shim 1.0 mm. Subsequent regulations will denote the puck as the S2. Now we will focus on how to find the washers thickness S1, located on the other side; - Set the transmission housing differential bearing outer ring on the side of the driven gear, where there is no shim. Insert the differential housing in the bearing housing; - Set the gearbox housing with a new gasket and tighten the five screws to 20 Nm;

|
- Set the dial gauge with bracket VW387 (Fig. 5.47). At the upper end of the drive shaft, place the bearing mandrel W385 / 17; - Set the leg indicator on the bearing mandrel with preload of 1 mm, and in this position lock indicator and arrow, set it to zero; - Move the bottom differential and follow the indication of the indicator, which may for example be 0.90 mm;
ATTENTION When measuring the axial displacement of the differential does not turn it, so as not to distort the measurement results. |
- The formula S1 = A + B + S2 calculate the thickness of the shim bearing differential where S1 - the thickness of the shim, mm; A - the axial displacement of the differential (measured value), mm; In - the value of the differential bearing preload, mm; S2 - the thickness of shims (a constant value) mm.
NOTE The magnitude of the differential bearing preload of 1 mm in accordance with the instructions, it turns out, if we add to the measured value of 0.40 mm. |
Example of measurement is as follows. Let the thickness of shims S2 = = 1,0 mm, the measured value of A = 0.90 mm, the amount of preload B = 0.40 mm. Consequently, the thickness of shim S1 = 1,0 + 0,90 + 0,40 = 2,30 mm; - Again, remove the gearbox housing and knock bearing race. Insert the appropriate shims and again Push the bearing race. First, always insert the thickest plate (possible washer 1 mm thick). There are washers of different thickness, only six values (0.15, 0.3, 0.6, 0.7, 0.8 and 1.0 mm) and therefore can form any combination washers;

|
- According to the instructions, you now need to measure the drag torque differential. To do this, pull on the output shaft of the torque wrench (Fig. 5.48) and crank shaft. For the new bearings the moment of resistance must be equal to 1.2 to 1.5 Nm, and the bearing of used - at least 0.3 Nm.
