ATTACHING THE VARIABLE SPEED SPIN DRIVE UNIT TO THE
REEL
The spin drive unit attaches to the end of the reel shaft or a
drive system component. Consult the cutting unit manual for
proper spin drive placement and attachment. Determine which
side to mount the spin drive. This will generally be the same
drive system component used for backlapping.
IMPORTANT: When spin grinding, the reel should turn in the
same direction as the grinding wheel. See FIG. 59.
Before positioning the spin unit let us familiarize ourselves with
the available adjustments and coupler/drive assemblies.
See FIG. 60 and 61
HANDWHEEL A--
Adjusts the scissor bar to move the unit up and down.
KNOB B (2 EACH)--
Loosen both knobs to move the spin motor forward or back.
KNOBS C & D--
Allow the spin assembly to be loosened from the support bar
frame and moved side to side.
When positioning the spin unit it will be necessary to
complete several of the above adjustments to properly align
the spin unit to the reel.
THE COUPLER ASSEMBLY INCLUDES:
RUBBER SLEEVE COUPLER: This is placed in the
corresponding flange coupler already mounted in the spin
drive shaft. See FIG. 61.
DRIVE COUPLER ADAPTER ASSEMBLY: This is mounted to the
rubber coupler.
NOTE: If the Drive Coupler Adapter is removed, there is a short
square drive shaft attached to the Adapter Sleeve. This can be
used with a socket if there is limited space.
ADAPTER SLEEVE: Connects the rubber coupler to the square
drive adapter.
SQUARE DRIVE ADAPTER: This is inserted into the drive
coupler adapter. This grinder has two square drive adapters,
a short and a long one depending on the position of the spin
motor. The square drive adapter has approximately 2" [51
mm] of movement . It will be necessary to move this when
attaching reel to spin drive unit. This adapter shaft has a
groove machined into it on the opposite end of the snap
ring. This groove is there to advise that you have reached the
maximum extension of the square drive shaft. If you cannot
connect the reel without extending past this groove, then the
spin unit must be repositioned on the tooling bar (Knobs C and
D). A 1/2" [12.7 mm] square drive socket or reel drive adapter
is used to connect the square drive adapter to the reel.
DO NOT EXTEND SQUARE SHAFT PAST
GROOVE, INSTEAD REPOSITION SPIN UNIT.
