4.29 Hydraulic Cylinder
Chapter 4: Removal, Replacement, and Adjustment Procedures
Replacement
WARNING:
Failure to use correct lifting methods could cause personal injury and
equipment damage. The weight of the lower frame will act as
counterweight during the lifting process. One person can safely do this
procedure.
WARNING:
Make sure you use the hydraulic cylinder with the correct part number
for this product. The surgical stretcher uses a hydraulic cylinder that
has a slower descent rate, but the replacement procedure is the same.
Be sure to use the correct hydraulic cylinder. Failure to do so could
cause personal injury.
CAUTION:
Leave the cylinder rod hold-down assembly in position until the
hydraulic cylinder is attached to the frame assembly. Failure to do so
could cause equipment damage.
1.
Lift the lower frame, and put the new hydraulic cylinder (I) into position.
2.
Install the four bolts (E), locknuts (C), and four spacers (F) to attach the
hydraulic cylinder (I) to the side tubes of the lower frame.
3.
Install the two screws (G), plates (H), washers (B), locknuts (A), and one
end plate (D) to attach the hydraulic cylinder (I) to the crosstube of the
lower frame.
4.
If necessary, install the spring on the bolt.
5.
Tighten the nuts (A) and (C) to 65 + 10 in-lb (7.3 + 1.1 N·m) of torque.
6.
Remove the cylinder rod hold-down assembly from the hydraulic
cylinder (I).
7.
Make sure the u-bracket pushes the release pin to the stop. If it does not,
adjust the cylinder release (see “Adjustment” on page 4-85).
8.
If one or more spacers were removed in step 2 of the Removal procedure,
install the spacer(s) on the hydraulic cylinder.
9.
Install the base shroud, bellows, and upper frame (refer to procedure 4.22).
