3. Turn the bolt behind the pillow block until proper
tension is achieved.
4. Use a spring scale tester to achieve proper
tension for each belt. Then tighten the pillow
block bearing bolts.
Important:
Tighten the pillow block bolts in the slotted
holes and recheck the belt tension and align
-
ment. Readjust as necessary to achieve cor-
rect belt tension.
5. Tighten pillow block bolts and jam nut on
adjuster bolt.
Step 3 - Hydraulic Motor To Eccentric Drive
Axle Belt:
Once the tension is set for the eccentric drive
belts, the hydraulic motor to eccentric drive axle
belt tension can be set.
The hydraulic motor is on an adjustable mount.
Threaded adjusting bolts inserted into threaded
holes on each side of the motor mount are used
to set the drive belt tension.
Use the following procedure to adjust the eccentric
drive axle belt.
1. Loosen the four bolts in the slotted holes on
the hydraulic motor mount just enough to allow
the motor to move. Make sure not to loosen
them too much.
2. Rotate the adjusting bolts to move the motor
and adjust the belt. Make sure the adjusting
bolts are rotated equally to maintain proper
pulley alignment.
Important:
Make sure the belt is not stretched tight. It
should be set with enough play to cause a
slight outward curve.
3. Tighten the 4 bolts in the slotted mount holes.
