MAINTENANCE & REPAIR

Using a suitable lifting device, position the as-
sembled coupling, intermediate, shaft and bear-
ings so the flexible portion of the coupling seats in-
side the outer ring attached to the engine flywheel.
NOTE
To ease installation, lightly lubricate the rubber por-
tion of the coupling with a non-petroleum based
lubricant such as vegetable oil or glycerin, or a sili-
con-based lubricant such as WD40" or equivalent.
Do not use petroleum-based lubricants, or any oth-
er substance which may soften or otherwise dam-
age the rubber.
Install the intermediate guards (29, Figure 3), and
secure the intermediate to the engine bellhousing
with the previously removed hardware (6 and 7).
Seal Reassembly and Installation
(Figures 2 and 5)
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-ven-
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain-
ers.
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 shaft sleeve, or replace it
if there are nicks or cuts on either end. If any com-
ponents 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 O-
rings and bellows 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 6).
