TS-2 Rod/Assembly Replacement
Disconnect power supply before
servicing or cleaning.
DO NOT plug in or operate the Test
ing Screen without all covers installed.
Refer to Figure 6 on page 12�
1. Unplug or otherwise disconnect the Testing Screen from
its power source, and lock out the connection�
2. Remove top and side/back covers�See Removal of Top
and Side/Back Covers on page 11�
3. Remove upper guide bearing screws�
4. Loosen the screws in the lower guide bearing and lower
threaded block�
5. Turn the clamp rod counterclockwise until you can pull it
up and out of the machine�
6. Remove and inspect the hardened steel wearing plate
which rests on the upper Vibrating Unit Assembly frame�
7. Use a magnet to lift one end of the wear plate to the
large clamp rod hole� Grip the wear plate with your
ngers or needle-nose pliers, and pull it up through the
hole� If the plate is worn, replace it�
8. To reinstall the wearing plate, drop it through the large
clamp rod hole, and use a screwdriver to position it so
that the holes line up�
9. If you are replacing only the clamp rod, remove parts
from the old clamp rod�
10. Drive the roll pin out of the collar, using a 3/16in drift
punch� Remove the collar and upper guide bearing
from the clamp rod, and install the parts on new
clamp rod�
11. If replacing the lower guide bearing, do so now, leaving
the screws loose�
12. If the threads on the lower end of clamp rod are
stripped, replace lower threaded block� Leave the
screws loose�
13. Reinsert the clamp rod, and turn it clockwise until the
upper guide bearing rests on the top of the machine�
14. Install upper guide bearings, leaving the screws loose�
(crescent washer goes between the head of the screw
and the top of the bearing)�Tighten the lower threaded
block screws� Finger-tighten upper and lower guide
bearing screws; then give each a 360° tightening with
a wrench� Front and rear screws on each bearing need
to be equally tight� If screws repeatedly loosen during
operation, use a small amount of medium-strength
(blue) Loctite�
15. Reassemble in reverse order� Run empty for a few
minutes to be sure the machine runs freely and quietly�
TS-1/TS-3 Hydraulic Clamping Systems
The TS-1 and TS-3 hydraulic clamping systems consist of a
low-pressure hydraulic pump, two hydraulic cylinders, and
two hydraulic clamp rod assemblies�
The systems use a medium-viscosity hydraulic oil such as
Shell Tellus 25 or Mobil AW 32�
Disconnect the machine from its power source and lock
out the connection prior to performing maintenance and/or
repairs�
Checking the Oil
Disconnect power supply before
servicing or cleaning.
DO NOT plug in or operate the
Testing Screen without all covers installed.
To determine the level and quality of the hydraulic oil:
1. Unplug or otherwise disconnect the Testing Screen from
its power source, and lock out the connection�
2. Release the pressure in the system by pulling the pump
handle all the way toward the front of the machine�
3. Observe the position of the internal pump cover before
you remove it� Its vent is slightly closer to the front
(handle) end of the pump than to the back� Gilson
recommends using a marker or other means to mark the
operator side of the cover to ensure correct orientation
during reassembly�
4. Remove the ve screws that secure the external pump
cover to the top, and lift the cover o
(Figure 3 on page 8)�
5. The reservoir should be lled to a 1/4in from the top,
and the oil should appear clean�
6. If oil is clean but low, ll tank to correct level and
reassemble�
7. If oil appears dirty, rst replace the internal pump cover.
Then drain and rell the system. See Draining and
Relling the Hydraulic System on page 12�
