Symptom
Abnormal sound is generated from the mainframe.
Cause
Friction between the drum shaft and the spring plate located behind the PCDU cover
Solution
Pull out the PCDU and grease the tip of the drum shaft.
Grease
Grease;
SHIN-ETSU KS-660
(p/n:G0049668)
Apply approximately
φ
1mm – 2mm of grease
to the tip of the shaft as
shown in the left photo.
Although the photos above are taken with the PCDU inner cover removed, the PCDU
inner covers DO NOT have to be removed to apply grease to the tip of the drum shaft.
If the PCDU inner cover is to be removed for other maintenance purposes, make sure to
pull out the PCDU before removing the cover to prevent breakage of the spring plate.
