8 Inspection & Maintenance
The seal pin locations for rotors with external bearings are identified and shown in Figure 8-4 and Table 8-11. These demonstrate
seal pins on both ends of the rotors. Figure 8-5 and Table 8-12 identify the seal pin locations for rotors with internal bearings.
These figures demonstrate only one seal pin on the drive end of the rotor.
Note: The procedure in Table 8-10 assumes that you have been referenced here from the procedure provided in Table
8-8, Inspecting and Replacing a Seal. Please review all Safety Precautions included in Section 8.3.4, Seal Inspection and
Replacement, before continuing.
Materials:
-
Hand drill. A drill that can rotate at 2000 RPM and has a head runout of no more than .0005” is acceptable.
-
Hammer
-
Seal pin installation kit, P/N 7404208-01
-
Pliers
-
(Optional) Seal pin jig 7404621-02
Table 8-10. Replacing the Seal Locking Pin
Step
Action
1
Grind off the top of the damaged pin. Be sure that the pin is flush with the shaft surface and is of a sanitary
finish (32 µin / 1.6 µm).
2
Mark the location of the new drill hole, to the dimensions specified below. Center punch the hole location.
Pre-drilling the hole with a smaller pilot drill will help in attaining an accurate diameter. Be sure that the shaft is
on a level surface, for drilling and that the drill is held perpendicular to the rotor surface..
3
Use the drill (# 17) included with the kit and drill a hole, to a depth of .375” (9.525 mm).
4
Using slow rotation (30 - 50 RPM). Next, use the reamer at 30 - 50 rpm. Take caution as higher rotational
speeds could yield an oversized diameter.
5
Clean out the hole thoroughly.
6
Hold the pin over the hole. Using a hammer tap the pin into place.
7
The top of the pin should protrude from the shaft, only .125” (3.175 mm).
