INSTALLATION (see FIG.2 and drawing at page 7)
1 Mount driving ring 31 onto engine flywheel.
2 Mount the pilot bearing 41 (greased for life), onto shaft 5 of the
power take off.
3 Mount the housing 1 onto engine flywheel housing. Position
power take off, paying attention to alignment between shaft 5
and pilot bearing 41, with its flywheel seat and driving ring 31
mounted onto flywheel. In order to align between housing 1
and flywheel housing, use 3 threaded rods with adequate
lengths, mounted 120° apart onto flywheel housing.
4 Through opening on housing 1, guide the teeth of the plates 23
into the driving ring 31. External housing should be orientated
to get the opening on vertical line. Tighten screws of external
SAE flange.
5 All power take-offs are supplied already greased. Only for
the HFF 211-L, after the first 100 hours of operation the
grease level should be checked. Removing the overflow plug
40, insert a screw driver into the cavity and check if the
grease is present. If necessary add grease (see BEARING
GREASE table page 6) through the greaser 11. For next
maintenance cycle see Maintenance table page 3.
CAUTION: Do Not Overgrease, through greaser 11, bearing
cavity. It might cause the main bearing to overheat and grease
to exit from seals.
6 Hit the shaft on the end, with a rubber mallet, to relieve any
pre-loading against the bearings that may result due to the
resistance of pilot bearing when being pressed into the
flywheel.
7 For HFF 211-L mount a support plate onto spacer 36, to
assure that the overhung load on the engine flywheel housing
is relived and any misalignment caused by this overhang is
relived, the support plate should be shimmed following the
procedure:
A-attach dial indicator to engine block (see FIG. 2 page 1) with
indicator anvil resting on bearing carrier at opposite direction
of belts.
B-set indicator to zero.
C-tension the belts
D-shim under support plate to return indicator to zero.
8 Rotary union 14 is supplied separately. Before installation,
grease O-Ring mounted on rotary union. Fix lockwasher 15
tightening screws 16.
9 Connect rotary union 14 through a suitable flexible hose.
10 Install a three way valve for oil pressure feeding.
operating oil pressure must be 25 bar (max 30 bar).
CAUTION: With the clutch disengaged the residual pressure
should be 0 bar. For pressure over 0 bar contact
TRANSFLUID.
11 At first start up, rotate engine by hand in insure there are no
interferences. After, run power take off with engaged clutch
and engine at half of max speed for not less than 10 minutes.
CAUTION: In case of a long start up period, mor than four
seconds, or engine kill, or clutch overheating, caused by a
sizable mass and driven inertial load, a BUMPING-IN sequence
may be used. Engage the power take off for no more than 3 or
4 times lasting one second each.

INSTALLATION (see FIG.2 and drawing at page 7)
1 Every 500 working hours add 13g (14 cc) of grease (see
BEARING GREASE table page 6) through the greaser 11.
2 After 3000 working hours it is recommended to purge the
old grease. The old grease should be replaced if the unit
has not been used for more than 6 months. Each bearing,
not the bearing cavity, should be packed with
approximately 19 g (20 cc) of new grease. Grease should
then be added through the greaser 11. To refill, to the
proper level (approximately 50%), a completely empty
bearing cavity will require approximately 56 g (60 cc) of
grease.
3 In case of taper roll bearings replacement, adjust as
follows:
A - Refill grease inside the bearings and the bearings cavity
as described above at point 2.
B - Tighten threaded ring 8, turning manually the shaft 5,
until some resistance of shaft rotation occurs.
C - Back off threaded ring, 1 - 2 notches.
D - With a rubber mallet (non metallic), hit the shaft on the
end, to seat bearing outer race against threaded ring. This
should give, approximately, the end play of 0.15 - 0.25 mm.
E - Lock threaded ring 8 through lock bearing retainer 12
and screw 10.
F - See item 6 and 11 on INSTALLATION table page 2.
4 It is advisable, every 4000 working hours, to check bearing
condition.
5 Check driving plate condition once a year.
MAINTENANCE for HFO-HFF 211-L
1 After the first 100 hours of operation the grease level
should be checked as described on INSTALLATION table at
point 5 page 2.
2 Every 500 working hours add 19g (20 cc) of grease (see
BEARING GREASE page 6) through the greaser 11.
Remove the overflow plug 40 to insure that the grease is
not overfilled.
3 After 3000 working hours it is recommended to purge the
old grease. The old grease should be replace if the unit has
not been used for more than 6 months. The bearing, not the
bearing cavity, should be packed with approximately 49g
(52 cc) of new grease and the cover remounted. Remove
The
the overflow plug 40 to control for overfilling.
should then be added through the greaser 11. To empty
bearing cavity will require approximately 89g (94 cc) of
grease. 100 hours of operation after purging, the grease
level should be checked as described on INSTALLATION
table at point 5 page 2.
4 It is advisable, every 4000 working hours, to check bearing
condition.
5 Check condition of driving plates once a year.
