2-14 PCS2 Service Manual
4. Using the 1/2" box wrench, fasten the left side of the cover hinge
using the Bushing Press Tool, P/N 38067-02, and tighten until the
bushing makes contact against the base hinge. (This tool will
physically push the bushing into the cover hinge.) Next, tighten the
Bushing Press Tool with a torque wrench set to 15/16 in./lb., until the
click of the torque wrench is heard. This will ensure a firm press of
the bushing against the base hinge. (See illustration below.)
Warning!
Failure to use a torque wrench set to the correct torque could cause
damage to the bushings and render the centrifuge cover inoperable.
5. Check to make sure there is no side to side movement between the
centrifuge cover hinge and the base hinge.
6. Remove the Bushing Press Tool from the left side of the centrifuge
cover. Apply a couple of drops of purple Loctite to one of the
previously removed headless shoulder screws and install in the cover.
7. Remove the shoulder screw from the right side of the centrifuge cover.
Apply a couple of drops of purple Loctite to the previously removed
headless shoulder screws and install in the cover.
Centrifuge Cover Reassembly Notes
1. The hex shoulder screws are designed to be completely tightened and
a nylon washer is fitted to provide a moderate amount of rotational
resistance for each cover half. In some cases, completely tightening
the shoulder screw may result in an immobile cover half due to an
oversized nylon washer. In either case, it is extremely important that
the shoulder screw is secured to the cover hinge with Loctite.
Otherwise the shoulder screw may loosen and cause the cover half to
vibrate.
2. Also, since the cover halves are hinged, they must be aligned so they
simultaneously touch the cover latch when closed.
3. First mount one cover half completely.
4. Lower the cover half and slide it closed against the cover latch.
5. Position the second cover half, with the nylon washer installed, along
the cover latch and the cover hinge.
6. Carefully slide the cover halves open (they are now geared), while
maintaining the proper cover hinge position, then raise the cover
halves.
7. Loctite and install the shoulder screw into the second cover half.
