Contact paint (permanent, violet - no. 330)
Acrilex Ref. 014123
After adjusting the pre-load of the planetary gear case bearings and the crown gear and pinion teeth backlash, it will be indispensable to control, and if necessary, to adjust the contact pattern of their teeth.
The correct contact pattern will be obtained varying the depth of the pinion or teeth backlash, and it is of fundamental importance for the durability of the assembly.
Checking the contact pattern
1
Apply ink for contact on two crown teeth 180 ° separated each other.
2
Turn the pinion forward and backward while braking, at the same time, the crown with a block of hardwood.
3
Compare the contact marks obtained with the examples below and, if necessary, make the necessary corrections:
B35.30-0037-01
In practice, generally the ideal contact pattern is not obtained. However, it is important that they do not touch in any place the outside edge of the tooth surface.
Correct contact marks
B35.30-0038-01
Contact pattern on the tooth's base (incorrect)
4
Correction: Increase a little bit the assembly distance (basic measurement) of the pinion.
Except on the rear axles HO6, HL6, HD6 and HL8.
B35.30-0039-01
Contact pattern on the tooth's head (incorrect)
5
Correction: Reduce a little bit the assembly distance (basic measurement) of the pinion.
Except on the rear axles HO6, HL6, HD6 and HL8.
B35.30-0040-01
Contact pattern close the thicker flanks of the tooth (incorrect)
6
Correction: Set the crown gear a little bit closer to the pinion.
B35.30-0041-01
Contact pattern close the thinner flanks of the tooth (incorrect)
7
Correction: Set the crown gear a little bit farther of the pinion.
