7.5.10 Fitting the belt drive
CAUTION
V-belts pulled on with force
Damage to the V-belts! Reduced service life of V-belts!
▷ Only pull on V-belts if this is possible without using any force.
▷ Only pull on V-belts by hand. Do not use any tools (e.g. levers).
CAUTION
Multiple V-belt drives
Reduced service life of the V-belts!
▷ Always replace the complete set of V-belts if individual belts are worn.
▷ Use V-belts of the same length.
ü The V-belts are free from burs, rust and dirt.
ü The motor has been mounted on the motor plate or motor bracket as specified.
ü The pump has been assembled as specified.
1. Use bushing 540.03 to fit pulley 882.02 on the motor shaft.
2. Fit bushing 540.02 on pump shaft 210.
3. Place pulley 882.01 on bushing 540.02.
4. Pull V-belts on pulleys 882.01/882.02.
5. Check the alignment of the pulleys.
6. Tension the V-belts.
CAUTION
Swelling of V-belts due to aggressive ambient conditions
Reduced service life of V-belts!
▷ Protect V-belts suitably from oil mist, dripping oil and other chemical
influences.
7.5.10.1 Using taper clamping bushes
ü All bright (machined) surfaces, such as the drilled holes and the tapered sleeve of
the taper clamping bush as well as the tapered drilled hole in the disc have been
cleaned and degreased.
1. Insert the taper clamping bush into the hub and align all connection holes.
ð Make sure all half threaded holes are matched with half unthreaded holes.
2. Lightly oil grub screws (sizes 1008 - 3030) or socket head cap screws (sizes 3535 -
5050) and screw them in. Do not tighten the screws at this stage.
3. Clean and degrease the shaft. Slide the disc with the taper clamping bush onto
the shaft until it reaches the required position.
4. If using a key, first insert this key into the keyway of the shaft.
Make sure there is a clearance gap between the key and the drilled keyway.
5. Evenly tighten the grub screws or socket head cap screws.
6. Check the tightening torque of the screws after 1/2 to 1 hour. Re-adjust the
tightening torque, if required.
