14.
Check exposed portion of coupling shaft (12) to be sure
you have removed all signs of rust and corrosion which
might prevent its withdrawal through the seal and bear-
ing. Crocus cloth or fine emery paper may be used.
Remove any key (12A), nut (12B), washer (12C), bolt
(12D), lock washer (12E), or retaining ring (12F).
15.
Remove coupling shaft (12), by pushing on the output
end of shaft. Inspect coupling shaft bearing and seal sur-
faces for spalling, nicks, grooves, severe wear or corro-
sion and discoloration. Inspect for damaged or worn
internal and external splines or keyway. Replace cou-
pling shaft if any of these conditions exist.
NOTE:
Minor shaft wear in seal area is permissible. If wear exceeds
0.020 in. (0.51 mm) diametrically, replace coupling shaft.
NOTE:
A slight “polish” is permissible in the shaft bearing areas.
Anything more would require coupling shaft replacement.
16.
Remove and discard seal ring (4) from housing (18).
17.
Remove thrust bearing (15) and thrust washer (14)
Inspect for wear, brinelling, corrosion and a full comple-
ment of retained rollers.
18.
Remove seal (16) and backup ring (17) from Small
Frame, housing (18) and backup washer (25). Discard
both.
