SPEED REDUCER
FIGURE 74 AND FIGURE 75
The speed reducer of the Forage Blower allows the op-
erator to use tractors equipped with a 1000 RPM drive-
line.
WARNING: Do not remove any guards or make
adjustments while the machine and/or tractor en-
gine is running.
CHAIN TENSION CHECK
The chain tension should be checked after the first ten
hours (approximately) of operation. Afterwards, checks
should be done every 100 hours of operation.
To check the tension of the chains (item 6) between
both input and output reducer shafts, turn the input shaft
clockwise and counterclockwise (item 1) with the output
shaft (item 2) secure from rotation. The chain should be
adjusted if the play ranges from 10 to 15 degrees.
CHAIN TENSION ADJUSTMENT
To adjust the reducer chains (item 3), proceed as per the
following instructions:
1. Lower the Forage Blower to the ground (page 25).
2. Uncouple the driveline (item 4) and remove the
guards (item 5).
3. Unscrew the twelve bolts (item 7) (6 bolts on each
side) of the covers (item 8) on the input shaft (item
1).
NOTE:
The covers (item 8) are eccentric thus allowing
to tighten the chains (item 6) when turning.
4. With the help of an hammer and screwdriver, slowly
turn both covers (item 8) in the same direction until
reaching the next cover hole (on both sides) with the
housing threaded holes.
NOTE:
It is a must to turn the covers in the same direc-
tion and with the same number of holes. If this
procedure is not followed, the input and output
shafts will no longer be parallel and serious dam-
ages could be caused to the reducer.
5. Check the chain play again as already described. If
the play is too high repeat step #4. If the play is satis-
factory install the guards and driveline back in place.
Check oil level before starting blower.
6. Check the oil level (item 9) and if necessary add
some oil (item 10) to reach the proper level.
