Repairing the cylinder block

Checks and measurements of the liners

Check the internal diameter of the cylinders for runout, tapering and wear, using a gauge (2) with a dial gauge (1), set to zero on the ring gauge (3) with a diameter of 117 mm.

NB: If you do not have a ring gauge with a diameter of 117 mm available, use a micrometer.

Measurements must be taken for each cylinder at three heights along the liner and on two perpendicular levels “A” and “B”.

Replace the cylinder if the maximum wear differs by 0.150 mm or the maximum runout by 0.100 mm from the values indicated.

Do not attempt to correct or deglaze.

NB: The cylinders are provided as spares with selection class “A”.

3.Align the shaft axially. Adjust the dimension (X) from the end of the shaft to the feed rake conveyor as follows:
LEXION 480 = 252 mm

4.Slide on the lock collar bearing (2) and both sheet-metal flanges (3) on the right and bolt them down.
5.Slide the gear on the shaft and align the shaft so that both gears are aligned.
6.Slide on the lock collars (4) on the left- and right-hand side and tighten by hitting in direction of rotation, then insert the set screw.
7On the left-hand side, place the parallel key in position, slide the V-belt pulley into place and tighten the clamping hub with the M 12 x 85 hex. bolt.

8.On the right-hand side, remove the gear and bolt down the bracket using the bolts that secure the sheet-metal flanges.
Then fasten the gear with the circlip and now bolt down the cover to the bracket with the M 6 x 12
hex. bolts.
9.Bolt down the hydraulic cylinder to the supporting arm using the M 8 x 65 and M 12 x 25 hex. Bolts and the eccentric bolts. Assemble the eccentric bolt so that there is still some free movement.

10.Adjusting the hydraulic cylinder:
– Press the drive motor down into the gear.
