10) Remove cap screws (62), locks (61), and bearing lock rings (14).
11) Install two screws temporarily to hold end plate to housing.
12) Remove the free end cover (7) rotor shaft socket screws (26 &
69), washer (25), spacer (57), oil slinger (21) (must be pried off
on KMBD-850C, 1200C, 1600C, 2000C, 2700C models), roll or
dowel pin (68), socket head screws (30) and oil retainer rings (14
& 15).
NOTE:
On KMBD-540C and KMBD-720C models, it is not
necessary to remove item 15 unless the end plate is being
replaced.
NOTE:
The flat head screws have nylok in their threads and may
be difficult to remove. Strike the head a couple of blows with a
flat face hammer for easy removal.
13) Using two yoke style pullers with pressure screws attached to free
end plate bores, pull end plate from housing. Tap out the bearings
(10).
Mechanical Seal Boosters –
Tap out mechanical seal (54),
spacers (123), and labyrinth seal (51).
Slinger Seal Boosters –
Tap out seal slinger (238) and spacers
(123).
The oil slinger stator (79) should not be removed unless it is
damaged or the end plate is to be replaced.
NOTE:
On some older units the oil seal slinger is made up of two
separate parts – items 238 & 129. The newer design combines
these two parts and is identified as item 238.
14) Using a single yoke puller with longer screws, push out one rotor
at a time making sure the rotor is vertical in the housing (for
support) while removing.
15) Remove the two temporarily installed screws and tap gear end
plate from housing and remove bearings and seals.
16) Clean all parts with a good grade of clean solvent and replace any
worn or damaged parts with factory approved parts. New
bearings, seals, and o-rings should be installed at each assembly.

General
The assembly procedure is generally the same for all series, but where
there are differences, notations will be made.
All vacuum joints, end covers, seal casings and plugs should be
sealed with an RTV Silicone Sealer, Kinseal or equal, unless o-rings
have been provided.
Dowel pins are used to locate end plates, housing and drive end
covers, in the proper location relative to each other. Be sure they are
in place.
