Models AC+3218 and AC+4329
Models AC+3218 and AC+4329 are operated by a pulley system
located on the underside of the base. To remove drive components
the entire blender and base must be tipped on its side. The motor
end should be toward the floor. The hopper, valve, inlet tubing,
casing, impeller, seal guard, and seal components should all be
removed before tipping the unit on its side.
1. On the top of the base, loosen the mounting bolts that secure the
drive to the base. The base is slotted so the motor may be slid
toward the blender.
2. Remove the drive belts.
3. Remove the bolts that secure the blender pulley to the underside
of the base.
4. Use those same bolts and tighten into the forcing holes. Finger
tighten.
5. Using the appropriate wrench, tighten the bolt until the pulley
releases from the bushing. Remove the bolt and the pulley.
6. Remove the tapered bushing from the shaft of the blender.
7. To remove the adapter ring and spacers, hold the adapter ring
to prevent it from falling while you remove the six cap screws.
8. Set the blender back down on all four legs.
9. Loosen the bearing housing from the base by removing the cap
screws .
10. Grasp the bearing housing with both hands and firmly lift it off the
blender base.
11. Remove the retaining ring.
12. Press the shaft from the housing. Use the appropriate puller to
remove the bearings from the shaft then remove the second
bearing from the housing.
13. Check the stub shaft for nicks or scratches.
14. All components should be checked for cracks or wear. Check
o-rings for damage. Inspect the legs for worn threads. Worn or
damaged components should be replaced.
Bearings are sealed and have lifetime lubrication. Worn or damaged
bearings should be replaced with identical bearings and be replaced as
a set.
