Assembly,
models 280, 285 and 290
NOTE! When assembling the upper gear housing it is
very important that the gears are correctly positioned
in relation to each other. This applies not only to the
backlash between the gear teeth but also to the gear
teeth contact. Correct gear teeth contact spreads the
load to which the gears are subjected over a larger
area of the gear tooth. This preventing gear break-
down and abnormal wear and at the same time provid-
ing a quiet operation.
3.
Rotate the bearings a couple of turns to allow them
to ”set”. Check the prestressing with a spring scale
and a piece of string, tied around the bearing housing.
The prestressing should be 5–10 Nm (3.69–
7.38
lb.ft.). Should the prestressing be too low, press
the roller bearing carefully a bit harder and if the pre-
stressing is too high, release the roller bearing some-
what.

NOTE! With run-in bearings the prestressing should
be 2.5–5 Nm (1.84–3.69 lb.ft.).

Press the larger roller bearing (1) onto the gear (2).
Use special tool 884263.

(
. Install the input gear (1) in the double bearing box
2) and press on the smaller roller bearing (3) in a way
that a slight prestressing is obtained. Use special tool
84263.
4. Determine the measurement “B” (fig. under point 5)
as follows: Use a depth micrometer and read the
measurement “C” between the edge of the double
bearing box and the inner ring of the bearing and
measurement “D” between the edge of the double
bearing box and the edge of the gear. Then calculate
the difference.

NOTE! Protect the tips of the gear teeth.
