Cylinder/Concave Clearance

Periodically, preferably at the beginning of

each harvesting season, check the position

of the concave in relation to the threshing

cylinder, in other words the cylinder /

concave clearance. Use tool No. R152308 

for checking, Fig 66.

Follow the instructions:

Set the concave adjustment lever to position

12 and check the clearance, which should 

be 12 mm at the front (between the first 

concave rasp bar and a cylinder rasp bar) 

and 6 mm at the rear (between the last 

concave rasp bar and a cylinder rasp bar). 

If this is not in order, adjust the clearance 

by nuts B at the lower end of the concave 

adjusting arm A, Fig. 67. The check 

measuring should be done in every concave 

edge.

BELT ADJUSTMENT

NOTE: Check the tension of all belts after

the first day of harvesting.

Adjusting Threshing Mechanism

Drive Belt (Fig. 68)

Engage the threshing mechanism with the

engine switched off. The clearance (X) between 

nut A and lever B (Fig 69) shall be 6...8mm. 

To adjust, loosen nut A and turn bushing C to 

required direction.

Cylinder Variator Belt (Fig. 69)

To tension the belt, tighten anchor bolts A

and C (on the housing) and the connecting

bolt B (between the variator arms).

Then you have to screw the connecting

bolt two turns per each turn of the anchor

bolts, to retain the transmission ratio of the

variator.

When tensioning the belt, rotate the pulleys

by hand so that the belt moves uniformly on the 

pulleys.

Check the belt tension when variator is

about in middle of range. The tension is correct 

when the measurement of the spring washer 

set in the lower end of arms is 23+1mm.

The arms shall be adjusted so that they

do not take a contact to the pulleys by minimum 

or maximum speed setting.

At maximum speed setting the belt shall

be even with the pulley edge in the ear beater 

shaft. At minimum speed setting the belt 

shall rise 5...7 mm over the pulley edge in the 

cylinder shaft.

Cutting Table Drive Belt (Fig. 70)

Engage the threshing mechanism with the

engine switched off. Slacken counter nut A

of the coupling arms adjusting nut and turn

up the upper nut B until the belt tension is

correct. Lock up nut A.

- 53 -

Grain Tank Unloader Belt (Fig. 72)

Slacken counter nut A on the draw bar and 

turn nut B to tighten. Lock up nut A.

Traction Hydraulics Belt (Fig. 73)

The belt tension is correct when the 

measurement X is 6..8 mm. To adjust, 

slacken nut A and turn the bushing B 

required direction.

Fan Variator belts (Fig 74)

Slacken nut A on the middle shaft of the 

variator pulleys and nut B. Then rotate Screw 

C, so that pulleys move in the direction of the

arrow and belts are tightened. After 

adjusting, screw up nuts A and B.

After adjusting tightness of belts, check

that free control range of pulleys is not too

long. Belt shall not rise over pulleys edge

at the ends of range. Adjust stop nuts D if

needed.

Reel Variator Belts (Fig. 75)

To tighten the belts slacken nut A at the 

end of the middle shaft and turn screw B 

so that the pulleys move upward tightening 

both belts tighten uniformly. After adjusting, 

tighten the slackened shaft.

Belt of the Working 

Hydraulics

Pump (Fig. 76)

Slacken fixing screws E and D of the pump

and crank back the pump to tighten the 

belt. The tension is correct when the 

deflection is approximately 15 mm when 

pressing the belt with a thumb midway 

between the shafts.

Spring-loaded Jockey Pulleys

Spring-loaded jockey pulleys automatically

tension the belts of the straw walkers, table

cleaning fan and the grain conveyor. If the

belts seem slack, they can be tightened by

moving the fastening of the pulley spring to

the next notch.

Stationary Jockey Pulleys 

(Fig. 77)

To tighten driving belts of the shaker shoe,

straw chopper and table auger, slacken the

middle shaft A of the jockey pulley and 

either by screwing nut B or by moving the 

jockey pulley by means of a suitable lever, 

tighten the belt as required.
