Cam adjustment Cam follower replacement [25802250]

Pickup cam follower bearing replacement

When pickup rotation becomes jerky, inspect the pickup

for a failed pickup cam follower bearing. The pickup cam

track is located on the right-hand side of the pickup.

To replace a cam bearing, proceed as follows:

1.

Pivot cover (1) to gain access to the cam follower

bearing (2) through the hole in the pickup frame.

2.

Rotate the machine (with a bar through the PTO

shaft yoke) until the bearing faces the access hole.

3.

Twine Wrapper [25802796]

Twine tension

Adjust the four compression springs (1) equally to an ef-

fective spring length A = 50 mm (2.0 in) for polypropylene

750 m/kg twine. Decrease the twine tension with thicker

twine, increase with thinner twine.

Correct twine clamp tension should result in a pull of 20 -

50 N (4.5 - 11.2 lb) required to pull the twine from the end

of the twine tubes with:

•

The spreader hooks in the middle position.

•

Pulling the twine through the twine feed opening,

from the bale chamber (under the raised tailgate).

ZIL10FCRB793AAA

1

NOTE: The twine tension is too high when difficulty is ex-

perienced in starting the twine to wrap around the bale.

It may be necessary to readjust the tension when chang-

ing twine, such as from plastic to sisal.

In case of troublesome twine starting, always check for

correct twine routing first.

NOTE: The twine tension is too light when the twine starts

slipping over the pattern pulley.

Twine Installation [25802849]

Twine feed rolls

Adjust the tension spring bolts (1) to a length (from nut to

eye) of:

X = 62 - 64 mm (2.4 - 2.5 in)

Excessive tension on the feed rolls may crush the twine

and cause stiff rotation of the feed rolls.

Insufficient tension on the feed rolls will make the rolls slip

on the twine at wrap cycle start. This could lead to twine

breakage.

the drive belt) with nuts (1) to obtain a distance X

= 69 - 71 mm (2.7 - 2.8 in) between the wrapper

support frame (2) and the left board of the feed roll.

2.

Adjust the right upper feed roll (3) with nuts (1) to

obtain a distance Y = 119 - 121 mm (4.7 - 4.8 in)

between the left board of the left upper roll race and

the left board of the right upper roll race.

Conveyor Adjustments [25803474]

Conveyor chain tension

The bar and chain conveyor is spring-loaded to automat-

ically keep it under correct tension at all times. Manual

tensioning is not required.

ZIL10FCRB817AAA

1

The stretch of the chain will gradually reduce the distance

(X) between the conveyor bars and the floor roll. This

distance should not be below (X) = 20 mm (0.8 in). A too

big a distance will increase losses over the rear of the floor

roller, particularly during the twine wrap cycle. Periodically

check this distance, remove the plate on the axle behind

the floor roller and observe from under the baler, tailgate

closed:

•

After first 100 bales made

•

Thereafter, every 500 bales.

Should distance (X) become less than 20 mm, then the

floor roll has to be moved forward. Contact your dealer

ZIL10FCRB823AAA

To service the conveyor, such as opening the chains, re-

placing bearings or bars, proceed as follows:

1.

Turn the baler by means of a bar through the PTO

yoke to expose the selected component at the top

of the baler, as shown in Figure 1. Do not forget to

remove the bar.

2.

Remove the tailgate guards on both sides.

3.

Obtain appropriate length pieces of 1" tube (3) (In-

side Diameter. 21 mm (0.8 in) and M20 nuts (2) to

compress the tension springs on both sides so as to

obtain slack on the conveyor, as shown in Figure 2.

4.

Install straps (1) as illustrated in Figure 1 to hold

the conveyor together in case the chains have to be

opened.

5.

The component can now be serviced:

•

To replace a bearing, remove the circlip. Mind

the washers behind the bearing. They take up

the end thrust between the bar holding chain

link, the bearing and the circlip.
