Bearing
All supplied bearings require lubrication at regular intervals. Main
shaft bearings are spherical roller bearings and are lubricated by
grease. To support thrust load, a spherical thrust bearing is placed
at the lower end of the shaft right below the spherical roller bearing.
Replacement of Upper Bearing
|
Remove
rotor and the rotor cover. |
|
Remove
the whole drive block housing from the block housing support. |
|
Remove
housing top cover, oil seal, locking washer, and bearing lock
nut |
|
The roller
cage of the spherical roller bearing should be removed from the
top - by using a mechanical puller to protect the outer bearing
race from any damage. |
Replacement of Lower Bearing
|
Remove
driven pulley cover. |
|
Remove
bushing sleeve to free the pulley from the shaft. |
|
Remove
driven pulley. |
|
Remove
housing bottom cover, oil seal, locking washer, and bearing lock
nut. |
|
The roller
cage of the spherical bearing should be removed from below - by
using a mechanical puller to protect the outer bearing race from
any damage. |
Important
note:
1. Bearing axial clearance is set at 2mm.
2. When bearing replacement becomes necessary, always renew both bearings
at the same time.
Rotor Removal
Remove the rotor by removing first the rotor cover located at the
top of the shaft that supports the rotor. The rotor would then be
lifted up through the top of the tub.
Enough space should be maintained at the top of the tub for easy removal
of the rotor and other internal parts of the DetrashPac drive block
assembly.
