Checking contact pattern

The contact pattern must be checked when the
set of gears, the housing or the bearing of the
drive bevel gear has been replaced.

L

Note:

The contact pattern is set with the spacer ring?(1) on
the drive bevel gear.

Remove grease from the tooth profiles of the
crown wheel and bevel gear and coat with engi-
neer’s blue or white oil paint.

Fit crown wheel, press into housing with palm of
hand and turn forward and backward several
times.

If the correct spacer ring is installed, the no-load
contact pattern as shown above should be ob-
tained.

L

Note:

The contact pattern is in the centre of the forward
profile “V”.
The contact pattern is nearer the large diameter on
the reverse profile “R”.

e

Caution:

The teeth should never touch at the small diameter!

If this contact pattern is obtained, a thinner spac-
er ring must be installed.

If this contact pattern is obtained, a thicker spac-
er ring must be installed.
