S320RD Operating Manual
42
The use of belt wax or similar substances to increase the friction coefficient is unnecessary and
damages the belts. Avoid any contaminations of oil, grease, or chemicals.
In order to grant a perfect output transmission, the belt drive needs continuous observation.
7.8 Fitting Belts
Remove the belt guard only when the blast wheel motor is at a standstill and the main
switch of the blast machine is in Safety Off Position as described in chapter 2.
1. Release the tension of the belt drive and loosen the central screw of the tensioner.
2. Insert the V-belt in the V-belt pulley grooves manually without forcing the belt.
3. Tension the belt as described in the following section.
4. Fasten the required protection equipment that was fitted on machine before.
7.9 Belt Tension
To achieve a maximum power transfer and live time the correct setting of the belt tension is
essential. Often belts are set with the wrong tension and fail before normal service time. Belts that
are set with too much tension may cause bearing problems on motors or bearing units.
Tension the belts as described below:
1. Mount the tensioner and push the
tensioning roller to the belt. Tighten the
flange screw slightly.
2. Grip the housing (2) with flat-wrench
(SW30) and set needful pre-tension
by rotating the housing in the required
direction.
3. Tighten the central screw.
Table with required angles of tensioners for belt tension:

Engine – Gearbox Timing belt 20
Gearbox – Bearing unit Poly-V belt 17-20
Gearbox - Fan Poly-V belt 15-18
Engine – Hydr. pump Poly-V belt 13-15
