Care and Maintenance
9.6 Compressor
If the Big Pack Baler is equipped with hydraulic brakes
the supply of compressed air for knotter cleaning is
provided through a compressor (1) mounted between the
drawbar beams. It is driven via a V-belt pulley (3)
mounted on the flywheel and a V-belt (2). The tension on
the V-belt can be changed by moving the compressor in
the oblong holes (5).
The oil level in the compressor must be checked daily
prior to use by means of the dipstick (4). If necessary,
refill oil (SAE 20 engine oil). The specification of the oil
that is required is listed in the “Technical data“.
• Move the retaining clip (2) on the air filter (1) up/
down.
• Remove the cover (4).
• Remove the filter cartridge (3), shake it out and clean
it from the inside to the outside with an air jet.
• Further disassemble the cover (4) and drive it out.
• Install the filter cartridge
• Place the cover on the filter and secure it in place
with support clips.
Make certain the filter pan is tightly sealed
with the air filter.
Filter cleaning
The suction air filter (6) must be cleaned
at least once a day or several times a day
in case of high dust load.
For heavy accumulations of dirt in the
filter, the aspiration attachment (7) can be
placed directly on the cab roof of the
tractor using a retrofitting kit (order no
287 363).

Rollers/cam follower rollers are subject to high
mechanical stress in the feed packer drum. Because of
this, they must be replaced when there is increased
wear (bearing play).
To do this:
• Turn the packer manually until the roller or cam
follower roller to be replaced can be loosened
through the opening (3) with an Allen wrench.
• Loosen the roller/cam follower roller
• Turn the packer further until the loosened roller/cam
follower roller can be removed through the opening
(4).
• Remove the roller/cam follower roller from the
opening (4) and install a new roller/cam follower
roller in the opposite order.

Rollers
Torque moment:
Large guide rollers: NukR 72 (M24 x 1,5) = 250 Nm
Small guide rollers: NukR 40 (M18 x 1,5) = 120 Nm
