Troubleshooting, fault clearance and repair
Shipping parts is very expensive or impossible in
some countries. That is why sufficient spare parts
for components subject to wear or at risk of falling
off/breaking and the necessary tools should be
carried (see Section 6.6.11).
Remedy
During the first 1000 km, the gears and clutch elements in a new
ROHLOFF Speedhub 500/14 gear hub hone into one another. This is
not a defect.
Run gear hub in over 1,000 km. Existing driving noises will
become quieter and gear changes smoother as a result. The
running-in period does not cause any limitations.
Apply a drop of Rohloff cleaning oil onto the hub seal through
the holes in the sprocket.
The dragging effect is reduced.
