–10 to +165 °F
–10 to +200 °F
PRECAUTIONS
COULD
required on the upper bearings of vertical shaft units.
See Lubrication section.
NOTE: The following mounting positions are generic
in that many other assemblies of feet and flanges
are available. The relationship of the input and
output shafts to earth (down) are significant.
CHANGING THE OUTPUT SHAFT
FROM K1 TO L1 (AND L1 TO K1)
Units should always be ordered to the required
mounting position. However, it is possible to change
output shaft location.
1. Drain oil from case. Remove the open bearing
housing. Remove the output seal and discard.
2. Lift out the output shaft assembly and the
intermediate shaft assembly.
3. Remove the closed bearing housing. Clean
machined surfaces.
4. Remove tapered roller bearing cups and shims from
each bore in each bearing housing and switch them .
(Place cups and shims removed from bores in open
bearing housing in closed bearing housing and vice
versa.)
5. Apply a 1/16" bead of Loctite 515 or equivalent
sealant to the closed bearing housing machined
sealing surfaces. The bead of sealant must go
completely around all bolt and dowel holes. Install the
closed bearing housing. Evenly tighten the housing
bolts. Lay the unit on the bench, closed bearing
housing down.
