COMPRESSOR BELT IN THE 

AIR CONDITIONER

Tension is correct when the belt deflects 

some 5 mm (50N = 5 kg) when pressed with 

the thumb.

To tighten the belt slacken locking nuts A and 

Turn regulating nut B, fig. P32.

Tighten screws A.

Place the Bows and Belt

Supports as They Were

Before Changing

Check, when changing the driving belts of

the threshing machinery, unloading of grain

tank and cutting table especially that the belt

supports and the bows round the pulleys are

re-fitted correctly. Mark the places before

removing the parts to ensure re-assembly

in the same positions. Tighten the new belts

after a few hours of working.

Always use original belts because their

quality has been tested by the factory and

meets the specific requirements.

Tightening of the Reel Chain

To tighten the reel chain lower the reel on its

supporting arms.

Grain conveyor Chain (Figs 79)

Check the tension of the chain and, if 

necessary, tighten after first 30 hours of 

harvesting and thereafter at intervals of 

about 100 hours.

Periodically check the condition of disc

sections.

To tighten the chain:

•  Slacken the nuts B locking the shaft of 

the sprocket A (Fig. 79)

•  Using appropriate lever move the 

sprocket outward so that the tension is 

correct.

•  Lock the nuts B.

Adjusting of Worn Disc

Sections (80a and 80b)

If the clearance between a chain disc and

the bottom trough is more than 1 mm (with

correct tension of the chain) the chain must

be adjusted so that it runs closer to the

bottom trough. Adjust on both side of the

combine.

Right side:

Slacken nuts A (Fig. 80a)on both shaft ends

Turn the plate B a quarter turns.

The centre hole in the plate B is eccentric.

When the three holes of the plate are in

bottom, the chain is its farest from bottom

of trough. If the plate is turned a quarter

turn, from three to two holes, the chain is

moved 1 mm closer to trough bottom. 

Turning the plate gives total 3 mm 

adjustment. When the side of plate without 

holes is at the bottom, no further adjustment 

of the chain is possible, and the discs must 

be replaced if the clearance between discs 

and bottom is wider than 1 mm

After adjusting the plates tighten the chain.

Left side:

Adjust the eccentric shaft of the curve

connecting the bottom trough and vertical

pipe as follows:

Slacken nuts A (Fig. 80b)

Turn the eccentric shaft corresponding the

right side. The eccentric of shaft is 3 mm and 

it is in the direction of the lever B. SO turning 

about 60 degrees moves the chain 1 mm.

After adjusting tighten the nuts.

The clearance between the discs and bottom 

trough can be checked after removing the 

sieve, by looking inside the machine.

Changing of Swinging Chopper 

Knives

If rotor knives (or knife) are either worn or 

damaged, they can be inverted or replaced 

by new knives.

NOTE: In the case of changing only one 

or some knives because of damage, it 

is necessary to change also two knives 

opposite side of the rotor shaft. Otherwise 

the rotor will start to vibrate because of 

unbalance.

To remove a knife, unscrew lock nut A, Fig. 

81, remove the fixing screw of the

joint and disassemble the joint.

Removing a Gib Key

by Tool (Fig. 82)

To keep a gib key in good condition, use tool

set R116007, Fig. 82, for removing it.

Removing and Refitting of a

Bearing Locked with an

Eccentric Ring

Removing:

•  Slacken the grub screw in the locking 

ring and open the eccentric ring by 

hitting the ring in the opposite direction of 

shaft rotation with a mandrel.

•  Unscrew the flange locking screws, 

remove the outer flange and pull the 

bearing off the shaft.

Refitting:

•  Fit the inner bearing flange.

•  Fit the bearing, locking ring and outer 

bearing flange. Fit the fastening screws 

of the flanges and tighten by hand.

•  Check the shaft position and tighten the 

flange screws.

•  Lock the locking ring in the direction of 

shaft rotation by hitting it with a mandrel.

•  Lock the grub screw on the locking ring.

The Correct Direction of the

Spring Cotter Notch

Note the position of the cotter notch in regard

to the load direction, fig. 83.

Some couplings have two cotters one

inside the other, in which case the notches

are on the opposite sides.
