II. Replacing the belt pulley of the belt tensioner of the ejector accelerator
The belt pulley is made of plastic and has one bearing. Since a belt pulley is used to tighten
the belt, there is a larger contact surface, which results in less slippage. Since this pulley has
no function as a coupling, there is also less wear and tear during frequent switching on and
off. Nevertheless, it is advisable to regularly inspect the condition of the V-groove and check
for possible play on the bearing. As soon as wear and tear is detected, the belt pulley must
be replaced.
(order code BA 564 705 002)
How to proceed:
• Disassemble the protective cover of the machine
(read § 15.1; page 99)
• The belt pulley is secured to the axle by means of a locking clip.
A special tong can be used to remove the locking clip from the
groove.
• Press the belt pulley off the central axle.
• Slightly sand the axle and apply some lubricant so that the new
belt pulley fits smoothly.
• Apply some extra lubricant to the bearing joints to avoid dirt
penetrating around the new belt pulley.
• Put the safety clip back into the groove.
• Re-assemble the black cover as it was originally. (read § 15.1; page 99)
