Addendum - New Bearing Design May 2010
Applies to MDT3, MDT4 and AFE424
The replacement top bearing, breaker and auger for the AFE400/424, MDT3 and MDT4
have been changed. They are significantly different from the prior parts. Two kits have
been developed.
The AFE400/424 bearing and auger kit is 02-4578-01.
The MDT3 & MDT4 bearing and auger kit is 02-4578-02. It also fits MFE400.
Each kit is complete with new auger,
top and bottom bearings and water
seal.
Removal of the auger is the same as
on page 9.
The top bearing can be replaced.
1. Get access to the top of the
evaporator.
2. Remove cap from top of breaker.
3. Loosen but do not remove bolt
holding auger to bearing.
4. Remove two phillips head screws from side of breaker.
5. Attach a T (like on page 9) to the top of the breaker.
6. Pull auger up and out of the unit.
7. Remove bolt holding auger to bearing, pull bearing from auger.
8. Remove retaining ring from inside of breaker, just above roller section. Early 2010
parts did not have a retaining ring.
9. Invert breaker and drive old bearing out of breaker.
10. Assemble new bearing. Bearing will be installed in two sections, first the roller
section and then the thrust section.
