INSTALLATION & MAINTENANCE
CLUTCH SPRING ADJUSTMENT
Loosen the set screw on the spring housing. Hold the
handle in running position 9:15-10:30 o'clock. Rotate
spring housing counter-clockwise about 3/4 of a turn or
until set screw is facing approximately 11:00 o'clock
position. Tighten set screw securely. See insert diagram
for correct spring housing set screw position.
REPLACING CLUTCH SPRING
The clutch spring may be damaged if the handle is forced
beyond limits. See diagram at right. Chuk/Changer should
be installed on lathe while clutch spring is being replaced.
Remove Chuk/Changer handle by loosening handle set
screw. (Note: Mark side of cam shaft from which handle is
removed in order to facilitate proper replacement. Loosen
the set screw on the spirng housing. Remove spring
housing. Discard damaged spring. Insert new spring short
end first into small hole in spring housing. Replace spring
housing. Care should be taken to be sure long end of spring
enters small hole in chuck housing. Replace handle and
follow the adjustment procedure under Clutch Spring Adjustment.
REMOVE CHUCK FROM LATHE
Always move handle straight down (6:00 o'clock) and leave it in this position if you have
any reason to remove the chuck from the lathe. If handle is moved, the clutch spring
(Part No. 7) may be damaged or clutch spring tension may be released. When clutch
spring is damaged or tension released clutch will not engage properly. See instructions
under Clutch Spring Adjustment and replacing clutch spring. Normally it is not necessary
to remove the adapter or clutch from the lathe when you return the chuck to the factory
for repair. If it is necessary to remove adapter or clutch refer to the installation instruc-
tions for your particular model lathe. Serious damage to clutch or adapter will result if
instructions are not followed.
OVERHEATING
A new or rebuilt Chuk/Changer will normally run quite warm (very uncomfortable to the
touch) during the break in period. The break in period will usually last several weeks
depending upon speed and amount of use. Worn collects, collets not screwed in all the
way or too long a stop (Part No.3) will cause overheating, especially in the front portion
of the Chuk/Changer.
SQUEAKING CLUTCHES
After several months of service, a clutch may glaze and develop a squeak. The squeak is
usually most noticeable as the lathe is coasting to a stop. Remove chuck from lathe (see
instructions under removing chuck from lathe) and lightly sand both fiber and steel clutch
surfaces. If squeaking persists and there is a presence of excessive amounts of dust
around the clutch area, the adapter is improperly mounted, causing misalignment of the
clutches. Refer to installation instructions for your model lathe.
