Changing Hand of Drive

Right/Left Hand Spare —

A Drive One Conveyor Drive can

be used in a right hand or left hand application with a single
low speed shaft extension and minimal change-over effort. The
Conveyor Drive housing top and bottom halves are identical
and therefore can be mounted on either end. Internal
lubrication troughs and oil passage function in either position
as well. Changing the drive from one hand to the other simply
requires repositioning of the top and bottom plate, magnetic
drain plugs, dipstick and breather.
To change hands of the drive, begin by cleaning the outside of
the housing to prevent contamination of internal components
and drain the oil. With inspection cover up, remove the AirMax
breather and dipstick pipe fittings from the housing. Remove
the top cover of the drive, threaded jacking holes are provide
to break loose the sealant if required, (eyebolts threaded into
jacking holes can be used for lifting). Remove internal oil
distribution pan if present, (See additional instructions below if
drive is equipped with an internal lubrication pump). Rotate the
drive 180° so the bottom plate is now up. Remove the bottom
plate, jacking holes are also provided.
Prepare top and bottom plate for reassembly by removing old
sealant. Loctite Chisel Gasket Remover or equivalent can be
used to aid in the removal of sealant. CAUTION: Gasket
Remover can soften and remove paint. Prepare the housing
surface in the same manner. Apply Loctite Activator 7649 or
equivalent to the mating surfaces of the top plate and housing
and allow to dry. Position the oil distribution pan in housing (if
required) with large opening over the low speed gear. The tabs
of the pan reside in the pockets of the housing and is secured
by the cover plate. Apply a continuous bead of Loctite 515
Gasket Eliminator or equivalent to the housing mating surface
to the inside of the bolt pattern. Assemble top plate to housing
with the inspection cover over the low speed gear. Tighten
fasteners to 85 N-m (62 lb-ft).
Remove pipe plugs from new dipstick and breather location.
Rotate the drive 180° so the newly assembled top plate is
down. Clean and prepare housing surface as previously
mentioned for top plate. Apply a continuous bead of Loctite
515 Gasket Eliminator or equivalent to the housing mating
surface to the inside of the bolt pattern. Assemble bottom plate

to housing and tighten fasteners to 85 N-m (62 lb-ft). Install
previously remove pipe plugs into old dipstick and breather
location. Coat pipe threads with Loctite Pipe Joint Compound
or equivalent prior to installation.
Position drive top side up. Install dipstick fitting in housing on
side opposite the low speed gear. Assemble AirMax assembly
fitting in housing on gear side. Reposition magnetic drain
plugs such that they will be in the oil sump. Coat pipe threads
with Loctite Pipe Joint Compound or equivalent prior to
installation.

Drives with an Internal Lubrication Pump —

When

changing the hand of a drive with an internal lubrication pump,
the pump must be moved to the cross-bar of what will be the
bottom of the housing. All previous instructions for changing
hands must be followed. In addition, to remove the oil pan,
remove the fitting holding the fill tube into the oil pan. Remove
the two fasteners mounting the pump bracket to the cross-bar
and any shims that are used.
Prepare the pump for mounting on the opposite cross-bar by
loosening the compression nut on the fittings securing the
suction and output tubes to the pump. The tubes must remain
in the same port on the pump. Rotate the output tube 180°
and tighten compression nut. The suction tube should be
rotated such that is will be approximately 10-20mm
(0.375-0.750 inches) off the bottom of the drive sump. Position
the pump in the housing. Align the pump gearset with a
straight edge. The pump gearset back lash should be set
between 0.15-0.56mm (0.006-0.022 inches) by adding or
removing shim beneath the pump bracket.
After proper gear alignment and backlash is achieved, apply
Loctite 242 threadlocker or equivalent to the threads of the
pump mounting fasteners. Tighten fasteners to 85 Nm (62
lb-ft) and re-check alignment and backlash. When installing
the oil pan, position pump output tube through coupling in
pan. Install fitting to secure output tube. Continue with
instructions as mentioned previously.
