inner circle should be even and smooth. When the last squeezing bar is installed,
protect the inner wall of body from being damaged.
(3) Dismantling and installing worm axle
Dismantling: Loosen the nuts and screw out the worm axle and pull out the nut,
take off flat keys and then worm can be taken off. Sometimes due to the poor seal
between the worms, the residues of oil cake might be stuck and make it difficult to
dismantle. So dismantling should be made when the machine is hot. Two persons
grasp the two handles respectively and turn the main worm axle facing down; put a
support on the ground and lift the handle and hit down, and worm will come off.
Installing: Clear the main axle, worm hole and key seat. Install 4 x 10mm keys first
and then worms in order. Please see Figure 4 for the installing position and direction.
Put them naturally. If it is over tight, clear axles and worm holes and see if there are
burrs. Remove those burrs and put them back again. After the worm is installed,
place the flat keys and screws into place. When the worm axle is installed and
against the pyramidal surface of the cake outlet, uses a spanner to tighten the nuts
anti-clockwise.
(4) Dismantling and installing bearing
Dismantling: Take off the end cover, loosen the handle and remove the cap, and put
a hard wooden bar of 20-30mm diameter into the hole and keep it closely against the
main axle ends; hit the other end of the wooden bar with a hammer to move the
bearing out of screw rod; put out the stop washer in the locking nut and loosen the
nuts, take off the bearings and bushings in order (See Figure 4).
Installation: the opposite of the dismantling.
