Once the fan is located on the shaft then insert the bearing housing bolts
into the bend bars. Push the bolts through from the inside of the square
formed by the bend bars to the outside. Place a washer and a nylock nut on
each bolt. By using the nylock nuts and washers on the outside makes it easier
to service the fan unit down the track.
This photo shows the fan, bend bars and bearing housing in place.
Note: all the nylock nuts have not been tightened at this stage.
The next step in the assembly process is to insert a cardboard square (there
are 3 or 4 provided in the carton to prevent scratching) between the fan
and the fan shroud.
While all the nylock nuts have not been tightened, the use of the cardboard
insert assists in the central alignment of the fan in the fan shroud. This is an
important step because if the tightening sequence of nylock nuts is incorrect,
then the fan will almost certainly hit the shroud.
Once the cardboard is in place then pass the remaining 4 bolts down
through the fan bend bars and use a nylock nut and washer underneath.
Once all four bend bar bolts are in place the fan is starting to take shape. From
here you should do a quick check of how the fan has come together.
1. Check bend bar alignment (left over right)
2. Bend bars in correct positional sequence
3. Fan in place underneath the bearing housing and located correctly
4. Cardboard inserts between the fan and the shroud for fan spacing
5. All the bolts, nylock nuts and washers inserted the right way
6. None of the nylock nuts should be tight
