Belt Drive
The drive assemblies consist of motors, belts, eyebolts and a step pulley.
The pulley diameters are sized to produce a cylinder speed of 37-39 RPM for 120 series models or 29-31 RPM for 170 and 200 series
models.
The step pulley assembly is used for speed reduction as well as a means of adjusting belt tension. The pulley mounting plate is
attached to the cabinet. The frame mounting plate has vertically slotted holes allowing up and down movement of the step pulley
mounting plate for belt adjustment.
Adjust the belt tension as follows:
1. Disconnect electrical power to the tumble dryer before
attempting any adjustments to the drive assembly.
2. Loosen pulley mounting plate bolts.
3. Loosen the upper nut on the final drive eyebolt.
4. Rotate the lower nut of the final drive eyebolt clockwise
until proper belt tension is achieved.
5. Rotate upper nut clockwise against the lower nut in order to
lock it into place.
6. Tighten pulley mounting plate bolts. Recheck belt tension.
7. If necessary, adjust the drive motor belt tension eyebolt
using a similar procedure.
8. Adjust blower belt tension on 120 series 50 Hertz tumble
dryers and all 170 series tumble dryers using a similar
procedure.
NOTE: Proper tensions for new belts are measured
with a Belt Tension Gauge:
