P.T.O. DRIVE SHAFT
Make sure the
EL 142
is resting on the ground and is maintained in a stable position. Clean and lubricate the
gearbox input shaft and slide the mating PTO shaft yoke in place. Before attaching the PTO shaft to the slip clutch
flange, it is essential that both mating surfaces are thoroughly cleaned.
Bring both components together and fix in place using the self-locking screws provided. Tighten all the studs to
a torque setting of
10 daNm (75 ft.lbs)
at the same time making sure that the flange is centrally seated.Tightness
has to be checked regularly.
After mounting the
EL 142
, stabilize the tractor 3-point linkage with whatever means are recommended i.e. the
bars, chains, etc.
Be sure the tractor P.T.O. shaft drive is disengaged and stop engine.
Couple the P.T.O. shaft to the tractor P.T.O stub.
Attachment is correct when machine is horizontal in work position.
With the machine resting on the ground, adjust the top link (P) length to a position where the tractor PTO stub and
the tiller input shaft are parallel.
In working position :
- The 2 angles (K) formed by the centre lines of the yoke and the sliding tubes must be equal and not exceed a
combined angle of 30° when working.
- The sliding tube overlap (L) must be at least 22 cm (8.5") (fig. 10).
With the machine fully raised on the tractor hydraulic linkage :
- The 2 sliding tubes must not completely overlap each other ; a gap (M) of 1 cm (3/8") should exist between end
of sliding tube and yoke.
- Both U joints (K) should operate approximately at the same bent angles which must never exceed 40°
(fig. 10).
Should the above mentioned conditions not exist :
- Shorten both tubes by an equal length (fig. A and B), chamfer edges (fig. C) and grease liberally (fig. D) before
refitting.
- To avoid noisy running of the PTO shaft when lifting the machine out of work, attach top link (P) so that it is almost
parallel to the lower links (fig. 10).
Important
: Always disconnect the tractor PTO drive before lifting the machine into the transport position,
otherwise permanent damage can be caused to the transmission shaft.
Repeat these adjustments each time the machine is mounted to a different tractor.
