7.8.4.5 Installing and adjusting the bearings of the pinch rollers or
conveyor rollers
A special tool is essential for installing or adjusting the bearings (adjustable taper
roller bearings) at the ends of the pinch rollers and conveyor rollers. The tool can be
ordered from ROPA under item no. 018156. However, this work is very rarely required
and can only be performed by experienced technicians.
7.8.4.6 Replacing radial shaft seals (Simmer rings) on the gearbox
Because the pickup roller bearings are exposed to a large amount of dirt due to their
design, soil may penetrate the gearbox flange over time in spite of thorough sealing.
For this reason the two radial shaft seals (ROPA item no. 246028) (31), the two inner
rings (ROPA item no. 240152) (32) and the two felt rings (ROPA item no. 246026 (33)
and ROPA item no. 246145) (34) on the gearbox side bearing of the pickup roller must
be replaced after approx. 300,000 t loading for safety reasons.
Remove the gear sleeve (8), the dirt deflector flange (35) and the bearing flange (36)
for this purpose.
Removing the gear sleeve (8) requires the ROPA special tool item no. 018766-16.
Remove dirt deposits on the inner sawtooth thread in the dirt deflector flange (35).
During reassembly always replace the O-rings (37) (ROPA item no. O-40050020) and
(38) (ROPA item no. O-40050020) at the same time.
