DPS in transmission 650 when
mechanical shuttle
Note! Tractors 8450---8750 and 8050---8150 with effect from
ser. no. F32104 have transmission 650. 6600---6800 have
transmission 650 from tractor number G01401 incl.
In the 650 transmission the DPS has been reinforced and
some dimensions have been changed. Bas ic construction
and function is similar to the DPS in transmissions 300 and
460. The number of friction discs in the clutches have been
increased in transmission 650, see page 440/2.
In the 650 transmission the pump drive shaft diameter (inside
the gearbox input shaft and the hollow clutch shaft) has been
increased due to the greater transmitted torque. This means
that the needle bearing and the seal ring inside the shafts are
also larger. In the 650 transmission these parts can be fitted
with a new tool ETV 894 200.
Repair instructions, see pages 444/9---10.
11. There is a piano wire under the securing ring between
clutches C1 and C 2 with effect from ser. no. F32509. The
securing ring can be squeezed via holes in the clutch drum.
Note! Other referencenumbers (in the picture on the previous
page) are the same as in transmissions 300 and 460 on page
440/15.
Important! Apply locking fluid Loctite 243 to the threads of
the planetary gear carrier bolts (6) in connection with repair
works. Tightening torque of the bolts:
--- 8.8, 23 Nm (earlier)
--- 10.9, 35 Nm (latest)
Tighten the bolts progressively. Tightening order, see picture
on page 440/15.
