Twin City BCFS Centrifugal Filtered Supply Fans - IM-4300 - Manual (Page 4)

Motor Installation
To prevent damage during shipment, the motor of this
unit has been installed at the factory, tested, then
removed and shipped separately. Please follow the
instructions below to reinstall the motor.
1. Fasten the motor plate to the bearing plate by insert-
ing the hinge pin in the holes and then putting a
hitch pin in the hole of the hinge pin.
See Figure 4.
2. Install the belts on the sheaves, apply tension and
tighten the bolt at the top of the motor plate or the
nut on the jacking bolt to maintain tension. The ideal
belt tension is to be enough so that the belt does
not slip under peak load. Do not over-tighten the belt
as it will severely reduce the life of the bearings.
3. Check the sheave alignment as shown in Figure 5
below and align sheaves with a straightedge if nec-
essary. Be sure the belt tension is rechecked if the
sheave alignment is changed.
Note: The belt tension will need to be rechecked after
the fan has been operating for a few days. There is an
initial break-in period for the belts in which they may
stretch.
