Reinstalling new brakemotor onto gear with
modular tapered input connection:
• Clean female taper of new motor's shaft completely
with petroleum solvent.
NOTICE: Do not lubricate the female taper end of the
motor shaft or the male taper of the reducer shaft.
Lubrication could cause the connection to slip in
