GRINDING with REFACER ATTACHMENTS
ROCKER ARM GRINDING-
The rocker arm is held firmly between two removable cones. The upper cone
may be assembled very rapidly by al fining the inscribed line with the flat on the
stem of the lower cone. Push upper cone down until it contacts rocker arm
bushing, then turn clock- wise until rocker arm is clamped firmly between the
cones. The cone and rocker arm assembly drops over the spindle which slides
on the swivel arm. For wheel dressing, see page 8. For grinding, lock the
attachment bracket in a convenient position by means of the knurled head
aluminum screw.
Locate the cone spindle in position where the full radius of the rocker arm
face is ground by swinging the swivel arm. Lock the cone spindle in place with
the knurled nut that forms its base. With one hand swinging the swivel arm, the
other hand keeps the rocker arm in contact with the wheel. Grind lightly and
remove only enough material to restore new face over entire radius.
LUBRICATING the REFACER-
Your Valve Refacer requires a few drops of high grade light oil in the oil cups, which are located in the work title, wheel
housing, workhead and under the belt ,guard. Add oil after every 50 hours of use, or oftener, depending on usage. In the
TYPE "T" WORKHEAD, oil cups should be filled with SAE 10 oil after every 30 hours of usage.
REPLACING V-BELT on WHEEL SPINDLE-
The attachment wheel is removed exposing the spindle sheave, this sheave is split and clamped together by three screws.
Remove these three screws and remove one-half of sheave. The belt then may be removed through the large opening.
The new belt can then be slipped into position and the half of sheave and attachment wheel replaced.
V-BELT ADJUSTMENT for TYPE 'T' WORKHEAD
Remove belt guard by removing three screws #366-10-32 x 1" Ig. Loosen two set screws #36885 in the large pulley.
Adjust the outer pulley flange by the three self-locking screws to obtain proper belt tension. Replace the belt guard.
