Correct Tension Pulley Installation for Kits CT 1038 K1, CT 1034 K1, CT 989 K1 and CT 731 K1

Problem:
The tension pulley supplied with the kit breaks apart after a short period of operation, normally resulting in damage to the engine.

Cause:
This is due to faulty alignment of the belt drive. The tension pulley is subjected to off-center loading and fails after a short running time.

Solution:
To ensure correct belt alignment, it is vital that the tension pulley holder is cleaned thoroughly, and that you subsequently check that the entire surface of the pulley is properly seated on the guide pin.
