7. Remove shaft locknut (
left hand threads
).
8. Firmly support the product head and carefully remove
it from the mutator shaft.
9. Insert plastic shaft skid in unit, install on top and
rotate shaft so skid is under shaft. Remove both shaft
and skid from unit. Place on a table or cradle.
10. Remove product head on drive end (if required) by
removing the shaft guard held in place by four bolts.
Rotate the head counter-clockwise to disengage.
Check the condition of the o-ring in the head before
reinstalling.
11. The mechanical seals are the same on top and bottom,
and if servicing is required:
•Remove the keeper o-ring and all seal components,
seal body with seal ring, backing ring, u-cup and
wavy spring. If it is a double mechanical seal, the
secondary seal and spring must be removed before
disassembling the primary seal.
•Inspect o-rings and seal faces for scratches or cracks.
If the seal parts require replacement, refer to pages 52
and 64 or pages 53 and 66.
•When assembling the
single mechanical seal
, place
the wave spring on the shaft, followed by the seal
backing ring and the u-cup with the opening of the
cup facing the body of the shaft. Position the seal
body and install the keeper o-ring.
•When assembling the
double mechanical seal
, place
the wave spring on the shaft and then the seal body
with o-ring. Position the seal body and install the
keeper o-ring, followed by the secondary seal and
wave spring.
•Check all seal assemblies to verify that they are
locked in position by the drive pins and that they can
be easily compressed.
12. Inspect the condition of the scraper blades and replace
if necessary. Install the new blades while the shaft is
on the cradle or table, attaching two rows of scraper
blades on the top of the mutator, and place the shaft
skid over the blades. Turn the mutator and shaft skid
over so that the skid is on bottom of the table or
cradle, and install the other two rows of blades on top.
Blades are always installed with the flat side up.

exchanger cylinder and lift up the mutator slightly to
remove the shaft skid.

and carefully place the product head with bearing on
the mutator shaft.
