7.1.1 Support the brake housing on suitable stands with bearing area being disassembled
on top, shaft vertical.
7.1.2 Remove cap screws & lock washers, securing bearing adapter. Do not unbolt cover
plate at this time.
7.1.3 Insert jacking screws in the threaded holes provided in bearing adapter. Alternately
tighten the cap screws as bearing adapter is drawn from housing. This procedure will
pull the bearing from the shaft.
7.1.4 With bearing adapter removed from brake, bearing is now accessible. Remove the
socket head cap screw from retaining cover plate to bearing adapter and separate
cover plate from bearing adapter.
Note quantity, if any, and thickness of shims located between the two parts.
7.1.5 Drive seal from position in cover plate with punch.
7.1.6 Bearing can now be pulled by hand from the bore of the bearing adapter.
7.1.7 Inspect bearing for defects and determine need for replacement.
7.1.8 Remove seals and O-ring from the bearing adapter. Seals are only accessible after
seal adapter is unbolted by removal of socket head cap screws retaining seal adapter
to bearing adapter.
7.1.9 Once seal adapter is separated from bearing adapter the seal can be driven from
place with a punch.
7.1.10 Drive seal from seal adapter with punch.
7.1.11 Seal sleeve is now visible over shaft in the bearing cavity. Four notches are provided
for pulling seal sleeve off shaft if removal cannot be accomplished by hand grip.
Avoid scratching or gouging seal sleeve surface with tools used in removal. Inspect
seal sleeve for defects and replace if grooves or pitting is evident.
7.1.12 Remove O-rings from shaft.
7.2 After Replacement of Bearing and /or Seals
The following outline will present a step-by-step method for assembling bearing areas on
either side of the Hydrodynamic Brake.
NOTE If one side of the brake is being disassembled, repaired, and assembled at a time,
correct centering of rotor to stators can be maintained. This is described in steps 7.2.12
through 7.2.16. However, if both bearing areas were disassembled before assembly of either
side was began, rotor-stator spacing must be measured to achieve correct centering of rotor
between stators. In this case steps 7.2.12 through 7.2.16 must be omitted, complete
assembly with steps 7.2.17 through 7.2.24.
7.2.1 Support the brake on suitable stands with bearing area being assembled on top,
shaft vertical.
7.2.2 Grease new O-ring and slide O-ring in place on shaft.
7.2.3 Slide seal sleeve on shaft over O-ring pushing tab at back of sleeve into notch
provided in shaft. Seal sleeve will not extend over shoulder on shaft when sleeve is
located properly.
7.2.4 Coat bore of bearing adapter with Permatex #1 form-a-gasket in location where seal
seats. Drive seal into bore making sure that seal lip is pointing inward. Do not
hammer directly on seal case.
7.2.5 Coat bore of seal adapter with Permatex #1 for-a-gasket. Drive seal lip inward, into
bore enough that seal case is flush with mounting flange on seal adapter. Do not
hammer directly on seal case.
7.2.6 Mount seal adapter to bearing adapter with socket-head cap screws.
7.2.7 Grease new O-ring heavily and position in groove on back side of seal adapter.

WIM-HB-000_A
Page 16 of 21
7.2.8 Grease seal lips and bore of brake housing, then slide bearing adapter assembly into
bore making sure thread zerk hole at outer edge of bearing adapter is at brake top
and unthreaded hole at outer edge is on bottom. During positioning of adapter
assembly in bore, care must be taken seal lips slide over seal sleeve without turning
backward and that O-ring does not drop from position. Secure bearing adapter by
cap screws and washers.
7.2.9 Bearing outer race is a slip fit, however inner race is a press fit and can be heated
before installation. Drive bearing on shaft until outer race is seated against bearing
adapter. Cover both inner and outer races with a protective plate to distribute
impacts, otherwise breakage of races may result. Bearing is positioned properly once
inner race contacts shoulder on shaft.
7.2.10 Coat bore of cover plate with Permatex #1 form-a-gasket. Start seal in bore, cover
with a protective plate, and then drive seal by striking plate. Seal lip must point
inward. Place cover plate over shaft and seat on top of bearing. Do not secure.
7.2.11 Continue by following either set of steps; 7.2.12 through 7.2.16 or 7.2.17 through
7.2.24, as described in the previous 7.2 NOTE of this section.
7.2.12 Raise the rotor-shaft assembly inside the housing until the rotor face contacts the
above stator face and travel stops.
7.2.13 Using feeler gages, measure the gap between the bearing adapter and cover plate.
7.2.14 To this measured value add .005” to .007” for bearing end play then combine plastic
shims and place the total between the bearing adapter and cover plate.
7.2.15 Rotate cover plate so bearing grease zerk at edge of cover plate is aligned with 2”
NPT outlet at top of brake. Fasten cover plate with socket head cap screws.
7.2.16 Assembly of this bearing area is now finished. If opposite side requires repair, see
7.1 for disassembly then follow assembly procedure of this section, steps 7.2.1
through 7.2.16.
7.2.17 Rotor-stator spacing must be measured to correctly center rotor. Mount dial
indicator fixture to brake housing, position indicator spindle on the end of shaft and
zero dial.
7.2.18 Raise the rotor-shaft assembly inside the housing until the rotor face contacts the
above stator face and travel stops. Record indicator reading. Release pull on shaft
and rest brake again on stands.
7.2.19 Temporarily bolt cover plate to bearing adapter, insert eyebolt, and position dial
indicator again.
7.2.20 Raise rotor-shaft assembly until bearing contacts cover plate and travel stops.
Record indicator reading.
7.2.21 Divide the first reading by two, subtract the second reading, the result is the shim
thickness. Release pull on shaft and rest brake again on stands.
7.2.22 Combine plastic shims from set and place an amount equal to the value calculated
between the bearing adapter and cover plate.
7.2.23 Rotate cover plate so bearing grease zerk at edge of cover plate is aligned with 2”
NPT outlet at top of brake. Fasten cover plate with alien-head cap screws.
7.2.24 Assembly of this bearing area is now finished. If opposite side requires assembly,
turn brake over, but follow assembly procedure of this section, steps 7.2.12 through
7.2.16 and steps 7.2.17 through 7.2.24 should be disregarded upon assembly of
second side.

7.3 LUBRICATION
7.3.1 Lubrication Of Seals and Bearings
NOTE: When unit is used on rigs: Grease bearings every trip.
Deep drillings my require greasing twice a trip.
7.3.1.1 Use No.2 water resistant (calcium base) grease (Texaco Novatex 2 or similar).
7.3.1.2 There are two grease zerks on either side of the brake. The zerks closest to the shaft are
for the bearings, the other zerks for seals. Both seals and bearings require lubrication after
initial break-in is made. Pump grease into zerks until excess is seen escaping from the
bearing grease relief and from the seal weep hole.
7.3.1.3 Once shop repairs have been completed, grease the brake for precaution against failure.
Seals and bearings will fail quickly if lubrication procedures are overlooked.
