O-Ring Inspection and Replacement

1. To inspect o-rings, raise the spindle shaft up so that
the end of the spindle shaft is flush with the bottom
of the spindle. Release any grip on the clamps and
observe the spindle shaft.
2. If the spindle shaft slips, the o-rings are in need of
replacement. If the spindle shaft remains where it is,
then the o-rings are fine.
3. To replace o-rings use the o-ring replacement tool
(74-107-003).
4. The top o-ring can be removed using the hook end
of the tool and sliding it to the o-ring through the slot
in the spindle.
5. The bottom o-ring requires that the o-ring first be
pushed out, using the small dowel pin. With the o-
ring pushed out slightly toward the center of the
spindle, it can be hooked using the tool.
6. When replacing the o-rings, use the tool to guide
each o-ring into place; the spindle shaft can be used
to help roll it into place.

Belt Replacement

1. Remove the spindle shafts from the tester.
2. Grasp the drive head cover on both sides and lift
straight up to remove the cover.
3. Locate the tensioner(s) for the drive belts. The
Classic 6 has one tensioner located near the center
of the drive head. The Elite 8 has two tensioners,
one near the drive motor at the rear center of the
instrument, and one near the monument toward the
front center of the instrument.
4. Use a 5/32 hex key to loosen the tensioner – do not
remove the tensioner.
5. Loosen and remove the belt from the spindles.
6. Route the new belt around the spindles and
tensioners in the same manner as the old belt.
