7 Operations
7.3 Rotor Lift Helper Plate to Aid in Serving Lower Components
The Rotor Lift Helper Plate (P/N 7401322) is used with the hydraulic lifting system to aid in the inspection of the lower head
assembly, seals and bearings. The procedure for operating the Contherms
™
Rotor Lift Helper Plate is provided in Table 7-5.
Refer to Figure 7-1 for component identification and location information.
Table 7-5. Operating the Rotor Lift Helper Plate
Step Action
1 Pull the handle on the Stack Valve Assembly down and lower the rotor until at least one full blade length of blade
pins are exposed.
2 Carefully remove the exposed blades.
3 Insert Rotor Lift Helper Plate around rotor and into same position product head assembly would normally be located.
The plate has same mating geometry as the product head. Refer to Figure 26.
4
Pull the handle on the Stack Valve Assembly up and slowly and gently raise rotor until next set of blade pins contacts
bottom of Rotor Lift Helper Plate and secures it into place.
5 Securely clamp the Rotor Lift Helper Plate in place as shown in Figure 7-2A.
NOTE: Before proceeding to the next step, if your Contherm
™
has a Rotor Hold Down feature, you must remove the
blue socket head cap screw (P/N 7401242-03) which is located at the bottom and inside the lower bearing assembly.
6 Slowly and gently lower the rotor assembly until the next set of blade pins inside the cylinder rest against the top of
the Rotor Lift Helper Plate. Ensure that the pins are resting securely on the plate and that the plate is securely in place.
7 Continue to lower the rotor and bottom head assembly. When you can observe that the rotor is being supported
by the Helper Plate, then you can remove and separate the bottom head assembly from the rotor to gain easy
access to lower seals and bearings.
Raising the Rotor
8 Before raising the rotor, reattach bottom head assembly to rotor, unclamp Rotor Lift Helper Plate, and then reattach
any rotor blades that were removed to their rotor pins.
9 To raise the rotor, reverse the steps above.
