Note: The Technician should be aware of
different worm gear variations that have evolved
with the products, as different replacement parts
may be repaired, depending on the date code of
the unit. Units prior to WL46 will have a 53
tooth worm gear and a 8 tooth motor. Units after
WL46 will have a 60 tooth worm gear and a 10
tooth motor. These variations are not
interchangeable. The assembly with the 53 tooth
worm gear are no longer available and if it needs
to be replaced with the new style, the motor will
also have to be replaced with the new style.
