 | 1. Secure the indicator on the retainer and set the measuring plate. |
2. Set to '0' indicator with 3 mm preload on the measuring disk (051). Height measuring disk (051) is adjustable.  | 3. Install the outer ring of the roller bearing (46b) on the inner ring of the pinion (47) and install a magnetic disk (052s). |
4. Insert the drive pinion into the measuring plate and measure the height of the pinion with tapered roller bearing and a magnetic disk.
5. Determine the difference between the Venue "B1" and height "B". Record the value (e.g., 1.79 mm).  | 6. Review the main deviation "a" pinion ("+" or "-") and write it down (for example, +0.06 mm). |
7. Depending on the prefix ("+" or "-") value for the pinion plus (if "+") or subtracted (if the "-").  | 8. Insert the probe (051b) in the gear housing. Screw him. |
 | 9. Insert the left (052e) from outside to inside and right (052d) from inside to outside measuring ring gear housing to lock. |
 | 10. Install meter (052a) with a measuring finger in the measuring device (052). Measuring finger screwed into the measuring part (052b). |
11. Set the measuring part (052b) in the measuring device and indicator is set to "0" with a 2 mm interference fit. Tightening the bolt, the indicator should be "0".  | 12. Insert the measuring device into the left hole in the gear housing. |
13. Measure the distance "A" between the regulator and the front side of the meter and record the positive ("+") or negative ("-") direction (for example, received - 0.01 mm and a negative direction). Positive or negative direction depending on the rotation of the indicator. The direction of rotation, with neutral position, counterclockwise determines the negative direction, clockwise - positive direction.
14. Determine the thickness of the lining:
The distance between the height "B1" and height "B" = 1.79 mm + Main deviation "a" pinion 0.06 mm = 1.85 mm + Difference "A1" between the regulator and the front side of the meter 0.01 mm = 1.86 mm thickness pads.
15. Remove the measuring device and measuring ring gear. Remove the meter. Insert the lining thickness in a certain gear. |
