8.9.4 Disassembly of The Contherms
™
Hydraulic Lift Cylinder
The procedure for disassembling the Contherms
™
hydraulic lift cylinder is provided in Table 8-28. Refer to Figures 8-18
for parts location and identification information while performing this procedure. Figure 8-18 shows the disassembly of a
Contherm
™
with a rotor hold down design.
WARNING
Refer to chapter 2, Safety, and section 8.1 Introduction
and safety before proceeding to disassemble the
Contherm
™
equipment.
This operation must be performed with the hydraulic
lift cylinder removed from the unit.
Table 8-28. Disassembly of The Contherms
™
Hydraulic Lift Cylinder
Steps
Action
1
Remove the piston rod (Part Number 7401173), cylinder head (Part Number 7401164-01) and piston
(Part Number 7401172-01) by releasing the retaining ring (7401243-07) located on the bottom end of the
lift cylinder.
2
If a leak is detected at the top of the cylinder, remove the cylinder cap (P/N 7401162-01) and replace
its O-ring (Part Number 7401137-02). This is accomplished by releasing the retaining ring (Part Number
7401243-07) located at the top of the lift cylinder and removing the cylinder cap.
3
If the piston rod has not been operating smoothly, the U-cups (P/N 7401109- 01) may be worn or faulty.
Release the retaining ring (Part Number 7401243-05) located at the end of the piston rod and remove the
piston (Part Number 7401172-01). Replace the two (2) U-cups on the piston. Refer to Figures 8-29 and
8-30 for parts location and identification information.
4
If a leak is found at the lower end of the lift cylinder, replace the two (2) O-rings (Part Number 7401137-02
and 7401137-04). Release the retaining ring (Part Number 7401243-05) from the piston rod (Part Number
7401173) and remove the piston. Replace both O-rings on the cylinder head (Part Number 7401164-01).
5
Reassemble both cylinder head (Part Number 7401164-01) and piston (Part Number 7401172-01) to
the piston rod (Part Number 7401173).
Apply a film of lubricant to all O-rings and U-cups to ease assembly. Insert the piston rod into the lift cylinder
from the lower end. Replace the cylinder cap (Part Number 7401162-01) at the top end of the lift cylinder
(Part Number 7401168). Secure both ends by replacing the retaining rings (Part Number 7401243-07).
