CLUMP MAINTENANCE SECTION (CONTINUED)
D. INSTALLING NEW SEAL ASSEMBLY (9) (Do not unwrap the new seal assembly until you are
ready to install. All parts of the assembly are packed in sequence of installation.)
1. To replace seal assembly (9), perform the operations under CLEANING, and remove clump
casing (8) by removing three bolts (39) that hold the clump casing to the clump housing (33).
2. After cleaning all parts, including clump shaft (17), begin reassembly of clump. Install grease
retainer (10) with the cavity portion of the seal facing outward. Rebolt casing onto clump frame
using three bolts (39). Using a light oil lubricant (such as 3-in-1 oil), install the ceramic seat
with its neoprene holder into the seal recess, making sure it is square with shaft. Lubricate
inside of the bellows assembly with a light oil lubricant and check to make sure the steel ring
is stuck (glued) to end of assembly. Slide bellows assembly onto the shaft and push until steel
ring is against ceramic seat.
3. Install the seal spring on the hub of impeller. After coating the threads on the clump shaft (18)
with an antiseize compound, install impeller (7), seating it securely.
4. Utilizing O-ring (4), reinstall suction cover (1) using eight bolts (5). At this time, check to see
that the clump runs freely. If impeller (7) rubs cover plate, you do not have impeller tight on
clump shaft (17) or suction cover needs to be readjusted. See IMPELLER CLEARANCE.
Tighten bolts uniformly using 15 lb-ft (20 N•m) on the torque wrench.
5. After reinstalling the suction pipe assembly, lubricate, and tighten the victaulic clamps. Service
the automatic lubricator.
