8.9.3 Reassembly of the Contherm
™
Table 8-27. Reassembly of the Contherm
™
Steps
Action
1
This procedure assumes that you have disassembled the Contherm
™
in accordance with all directions
provided in Table 8-26.
2 Place the cylinder assembly into the trim sheet, 1.50-inch media connection end first. Align the media
connection with the mounting connection of the trim sheet.
3 Replace the six hex head bolts at the lower end of the trim sheet. Refer to figure 8-16.
4 Return the cylinder head trim assembly (Part Number 7401141-01) to the open end of the trim sheet by
sliding it along the hydraulic lift cylinder. Using a soft head mallet, insert the cylinder head trim assembly
(Part Number 7401141-01) onto the trim sheet. Align the holes with the end hub and attach with the six,
hex head bolts.
5
Bolt the lift beam to the product head and replace the retaining ring (Part Number 7401243-06).
6 Re-attach both product head assemblies to the cylinder end hubs. Replace the bearing and drive system
assembly to top product head.
7 Tighten all clamps.
8 Lift the Contherm
™
back onto the mount, replacing the locknuts (Part Number 7401266-01). Refer to
Chapter 6, section 6.4, Figure 6-3. Do not touch seal faces. Clean seal faces with alcohol or solvent before
inserting into the cylinder.
9 Connect the lift cylinder hydraulic connections. Purge the air from the hydraulic lines. (Refer to Chapter
Six, section 6.7, Installation.)
10 Using the hydraulic rotor lift system, lower the bottom head assembly and install the rotor, top spline end first,
with the seals properly attached, into the Contherm
™
. Carefully insert the lower end of the rotor into the
lower head assembly to avoid damage to the seal bushing and the lower bearing.
11 Install the scraping blades onto the rotor. Refer to Chapter 8, Section 8.5, Scraping Blades. Use blade
funnel tool to protect equipment.
12 Raise the lower product head assembly and rotor, guiding the scraping blades, into the cylinder and secure
with clamp. If the top spline end binds, carefully rotate the rotor slightly to better engage the spline teeth, and
try raising the rotor again. Be careful not to dislodge the seal at the drive end.
13 Connect all media supply and return lines to the Contherm
™
.
14 Attach any product piping to both product heads.
