Cleaning and Service Tips
• The slurry cup rotators are moved on fluorocarbon polymer bearings that have low
friction resistance and require only occasional lubrication. It is recommended that the
rotators be examined periodically and lubricated with light lubricating oil.
• Never replace the power cord with an inadequately rated power cord (see Section 5 –
Replacement Parts for the Chandler Engineering part number).
• Dishwashing liquid and water are recommended for cleaning the cabinet and removable
parts.
Refer to Figure 4 for the following steps:
1.
Disconnect electrical power.
2.
Remove back protective cover plate.
3.
Loosen bolts on motor mounting bracket.
4.
Push motor forward.
5.
Remove belt from motor timing sprocket.
6.
Remove the ten (10) outer screws on the deck cover, remove the entire assembly from
the water bath, and set it on blocks to prevent damage to the rotators.
7.
Remove the four (4) inner screws on the deck and remove the top plate from the
bearing housing.
8.
Loosen and rotate retaining tabs securing the rotators in the bearing housing.
9.
Pull rotators.
CAUTION: Watch for loose bearings when rotators are removed!
10.
Clean rotators, bearings and bearing assembly with soapy water using Dishwashing
liquid. Rinse with water and dry thoroughly.
11.
Place bearings in bearing assembly. (CAUTION: Use 38 bearings per rotator!)
12.
Apply oil generously to bearings.
13.
Re-assemble instrument.
14.
Pull motor back only enough to prevent belt slippage. Allow approximately 1/2"
(12.5mm) slack in drive belt to prevent excessive side thrust to bearings.
(CAUTION: Do not over-tighten belt!)
