Basic Service
Tracking Clips are essential to the function and preservation of the teat belt cover. It is worth
replacing these often because they keep the teat belts centered, putting less load on the
bearings and preventing the teat belt cover from wearing too quickly. You should replace these
as soon as they are worn halfway through.

To replace a tracking clip rotate, the old tracking clip a quarter turn in the direction allowed
(one tracking clip gets rotated clockwise, the other gets rotated counterclockwise) and pull
inward away from the cover, they should just pop out.

Place new tracking clips in just like you took the old clips out, you should feel them snap into
position when they are fully rotated horizontally.
Drive Pulley should be replaced when it is loosing traction to the drive belts. If it is worn, you will
notice the bottom of the groove is shiny and smooth, indicating it needs to be replaced.

To replace the pulley you need the pulley tool (P/N 611977). Insert the pins of the pulley tool
into the two small holes on the pulley, then with the included 5/32 Allen wrench take off the
button head screw holding the pulley to the output shaft.
NOTE : You must hold the pulley tool stationary and turn the Allen wrench counterclockwise to
loosen the screw.

With the screw out, you can pull off the pulley, but keep track of the 3/32 brass dowel pin key.
NOTE : A pulley might be corroded onto the output shaft. Two small flathead screwdrivers
prying on either side of the pulley will help get it off.

Slide the new pulley onto the shaft along with the small pin. Tighten the screw down to hold it
in place using the pulley tool.
