1. 1. 1995
15. 5. 1993
Reconditioning reverse shuttle (Op.
no. 442) .
Note! In the instruction below a tractor is used which has no
quick---shift gear. On these models, the reverse shuttle has a
flange which is shown in the figures. In addition, on E---
models there are two speed sensors on the front face of the
reverse shuttle housing. Also impulse discs are only on
reverse shuttle units which are fitted on E---models. Casting
of the reverse shuttle housing is a little different on tractors
with Delta Powershift.
A. Removing reverse shuttle
1. Split the tractor frame between the gearbox and fuel tank
(see instr. 4411Aor instr. 423 1A).
2. Detach the quick---shift gear, if fitted: 2---step quick---shift
gear, see instr. 441 1B. 3---step quick---shift gear, see instr.
444 1A points 1 --- 4 .
1. Disconnect the oil pipes from the reverse shuttle.
2. 2 --- s t e p q u i c k --- s h i f t g e a r : Detach the oil distributor piece
from the front side of the housing and unscrew the bolt behind
the piece (otherwise the bolt prevents detaching of the hous-
ing)
Important! If the tractor has Delta Powershift, the oil distribu-
tor piece is fitted inside the reverse shuttle housing and it is
unnecessary to remove it.
3. On AC IV models: Remove the gearbox speed sensor on
theRHsideofthereverseshuttlehousing.
3. Pull out the reverse shuttle selector lever (on the RH side of
the gearbox) until the lever inner end releases from the selec-
tor fork rail groove.
4. Support the reverse shuttle with a suitable lifting device and
unscrew the reverse shuttle fixing bolts. Pull the housing
straight out.
Note! Easiest way to remove the reverse shuttle is to use a lift-
ing device which has a support bar that can be pushed
through the reverse shuttle input shaft as in figure above.
