How to install Electric Motor, Gearbox, and Final Drive
These instructions must be followed EXACTLY. USE LOC-TITE, Blue
1) Install the flangette bearings to the roller frame. The flangettes should be to the outside of
the frame and the bearings should have the exocentric collars towards the outside of the
frame also. Install the bolts so they will hold the bearings in place but the bearings will
slide if needed.
2)
Slide the drive shaft through the bearings, installing the sprocket and key.
3) Install the shaft keepers outside the flangettes at this time keeping the locking bolts loose
and not touching anything.
4)
Set the gearbox on the gearbox-mounting pad.
5) Install the four bolts and only tighten to a snug fit. You must be able to slide the box by
hand and it must sit flat on the mounting pad.
6) Now slide the drive shaft so the end of the drive shaft and the output shaft of the gear box
touch. Line up the keyways.
7) Install a full key and a split shaft collar over both shafts keeping the ends of both shafts
touching and in the center of the shaft collar.
8) Tighten this split collar watching the bearings and flangettes; they should not be forced
left or right but may move up or down within the slots. Move the gearbox if needed to
keep the bearings and flangettes in a free state.
9)
Next tighten the flangettes watching that the bearings don’t move in any direction.
10) Now tighten the four gearbox mounting bolts.
11) At this time, turn the lock bolts on the shaft keeper so they touch the lock pad. Tighten
the jam nuts so as to hold the shaft keeper and bearing in place.
12) Set the exocentric collars and tighten the setscrews. With a punch, turn the exocentric
collar in a clockwise direction, and then tighten the setscrew.
13) Set the sprocket the same distance from the inside wall of the roller frame as the roller
sprocket. Tighten the setscrews and shaft collars on both sides of the sprocket.
14) The Electric motor comes with a plastic bushing over the shaft. Check the key between
the plastic bushing and the motor shaft. It is very important the key is as long as the slot.
15) Some motors have a spacer between the motor and gearbox; it must be installed if it was
there when disassembled.
16) Install the chain between the drive shaft and the roller. This chain should be installed with
as little slack as possible. Avoid the use of ½ links.
17) Install the idler-adjusting sprocket. Shim the idler sprocket so it fits in the center of the
chain, as closely as possible.
