Problem:
Belt drive failure soon after installation of the kit due to the
tensioning pulley breaking of.
Cause:
The tensioning pulley was unable to gain full supporting pur-
chase on the engine. This resulted in the action of lateral forces
on the stud bolt, which subsequently broke.
Solution:
The stud bolt must always be inserted as far as it will go into the
engine so that the screwed-on contact surface of the tensioning
pulley can be fully supported on the cylinder block without any
additional loads being generated.
