22-link drive chain for Holzmann and Bernardo planer thicknessers

This 22-link drive chain is a replacement spare part suitable for several Holzmann and Bernardo planer thicknessers, including the Holzmann HOB305ABS and HOB305ABSSMW2 as well as the Bernardo PT305D and PT305DS.

It corresponds to position 158 on the exploded parts diagram of the relevant machines. This position number, together with the 22-link configuration, helps distinguish this chain from other drive chains fitted to the same machines.

This chain is part of the planer thicknesser's transmission mechanism. Replacement may be necessary when the original chain becomes worn, stretched, damaged or broken.

When should you replace the drive chain on your planer thicknesser?

With regular use of the machine, the links and joints of a drive chain can gradually wear. Several signs may indicate that the chain should be inspected or replaced:

• the chain has excessive play or has become stretched;
• one or more links show signs of wear or damage;
• unusual noises are coming from the transmission mechanism;
• the chain-driven mechanism operates irregularly;
• the chain jumps or no longer remains correctly positioned on the sprockets;
• the original chain is broken.

When replacing the chain, it is also advisable to check the condition of the sprockets, shafts and other components of the transmission system. Heavily worn sprockets may cause incorrect operation or premature wear of the new chain.

This 22-link drive chain is suitable for the following machines:
