assembly. Be careful to center the drill in the
threaded grease piping hole and not damage the
threads. Deburr the hole from the inside of the seal
liner after drilling.
See Figure 4, and inspect the engine stub shaft as-
sembly (6) for damage. Small scratches or nicks
may be removed with a fine file or emery cloth. If
excessive wear exists, remove the hardware (2 and
3) and separate the bellhousing adaptor (1) from
the engine bellhousing. Disengage the hardware
(4 and 5) and remove the stub shaft assembly. Re-
assemble the new stub shaft assembly and bell-
housing adaptor, and proceed as follows with seal
installation.
Position the intermediate against the bellhousing
adaptor (1, Figure 4) and secure the intermediate
in place using the attaching hardware (20 and 21).
Be sure the threaded seal lubricant hole in the in-
termediate is at the 10 o’clock position when facing
the seal cavity in the intermediate.
Clean the seal cavity and shaft with a cloth soaked
in fresh cleaning solvent.
Most cleaning solvents are toxic and
flammable. Use them only in a well−
ventilated area free from excessive
heat, sparks, and flame. Read and fol-
low all precautions printed on solvent
containers.
The seal is not normally reused because wear pat-
terns on the finished faces cannot be realigned
during reassembly. This could result in premature
failure. If necessary to reuse an old seal in an emer-
gency, carefully wash all metallic parts in fresh
cleaning solvent and allow to dry thoroughly.
Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non-oil based solvent and a clean, lint-free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak-
age. Clean and polish the seal spacer sleeve, or re-
place it if there are nicks or cuts on either end. If any
components are worn, replace the complete seal;
never mix old and new seal parts.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.
To ease installation of the seal, lubricate the pack-
ing rings and seal liner with water or a very small
amount of oil, and apply a drop of light lubricating
oil on the finished faces. Assemble the seal as fol-
lows, (see Figure 5).
