MAINTENANCE
Building the Rubber Tube Assembly
When cutting rubber tube to length, it is very important to cut the ends square, without nicks or wavy
edges. Heavy tin snips work well. Any uneven cuts will not let the rubber tube seat properly in the
end cap, resulting in an unreliable assembly subject to failure under pressure.
Before assembly, clean ends of rubber tube inside and out to make sure all mold release agents or
other foreign coatings are removed. This will help prevent the rubber tube from squeezing out of the
cap when the retaining nut is tightened.
1. Cut rubber tube square at each end.
2. Install the end cap
(1)
on the rubber tube and mark its
position on the tube
(2)
. Remove the end cap.
3. Insert the tube fitting
(3)
deep inside the rubber tube.
NOTE:
If the assembly uses a tube stiffener, insert it into
the rubber tube first and attach it to the tube fitting. Then
insert the fitting into the rubber tube.
For rubber tube diameters 11/16" and under,
reinstall
the wooden dowel inside the tube. (This will aid in
loading the tube into the shaft.)
4. Fit the end cap
(4)
over the tube.
5. Squeeze the tube
(5)
to force the tube fitting back toward
the end.
6. Apply Loctite to the tube fitting threads and install the
nut
(6)
. Do not tighten.
7. Secure the shaft in a round clamping fixture.
8. Tighten the nut to draw the tube fitting out until fully
seated in the end cap.
9. Tighten the nut to torque specified on page 12.
10. The end cap must be within 2 mm of the mark on the
rubber tube. Tube fitting threads should be perpendicular
to the rubber tube. If crooked, loosen the nut and repeat
the procedure.
11. Repeat the procedure for the non-valve end.
