Lubricatio :
For lubrication of the newly replaced Capstan Drive
Ass ' y, the following should be observed.
Apply a drop of a light machine oil of good
quality (e.g.: TEAC TZ-255) with an oil ap ­
plicator to the shaft of the Flywheel and spread
oil evenly over the shaft with a flannel cloth.
After installing the Flywheel, be sure to clean the
tape moving portion of shaft with TEAC
TZ-2 1 A Head Cleaner or with pure alcohol.
®
Since the Capstan Drive Ass ' y is a precision part,
TEAC specially distributes the Flywheel and the
Capstan Housing Ass ' y as a whole assembly.
Hence, always replace the Flywheel together
with the Capstan Housing Ass ' y.
Clean all driving surfaces of the Flywheel and the
Drive Belt with TEAC TZ-2 1 Cleaner kit ( " A "
for Flywheel. " B " for Belt) or with pure alcohol.
Do not bend the Capstan Shaft as this will
increase wow/flutter or speed deviation.
During re assembly re-attach the Drive Belt with ­
out twisting or stretching it.
The Belt should always be attached right and in
the predetermined place.
