- Set out the turret in open position (unlocked)
- Remove the screws 714 and 715
- Remove all the support ( S ) complete of gear 712, (to facilitate the removing of this last, hit the ends ( E )
with a plastic hammer).
- Remove the supplementary motor ( M )
- Take off the toolholders disk
- Disassemble the flange 716
- Extract the pin 717 and the idle gear 718
- Take off the dowels 719 and the screws 720 & 720a
- Extract the plate unit 721 and the counterplate 722
- Take off the dowels 723 and the screws 724
- Separate the plate 721 from the counterplate 722
- Remove the central gear 705 complete of bearing 727 and thrust blocks 728
- If the disassembly of the components inserted in the support ( S ) is required:
extract the lock pin 713, remove the gear 712 complete of coupling 708, reel 706, lead nut 730 and pins 707
or 707a
- To disassemble the rack 711 the cover 731, and the levers 709 & 710 must be removed.
WHENREASSEMBLINGEVERYTHING
Oil all the retaining rings (O-Rings etc.) with grease, brake all the screws with "Loctite" and lubricate all the
mechanical components; beside it, for what the assembly of the elements belonging to the support unit ( S ) is
concerned, follow the following instructions:
- Insert the rack 711 complete of springs and containers 701 in the seat L; by using a small pin (as on table page
21) and with a suitable manual press compress the spring 702 with value (C) (see page 21); in this condition it must
be inserted the unit ( I ), composed by the gear 712, by the reel 706, by the lead nut 730 and by the pins 707, in the
seat in such a way that the tooth ( D ) of the reel 706 fit the space ( V ) of the rack 711 and that the slot ( A ) is in
correspondence with the hole ( F ).
Insert the lock pin 713 in the seat ( A ).
Eliminate the press action.
Push the gear 712 towards the bottom of the seat ( Z ) in such a way that the lead nut 730 goes in the ledge.
In this condition, the extremity (E) of the coupling 708 must be on line with the extremity ( E ) of the gear 712; if this
does not happen, the reason is caused by the insertion of the tooth ( D ) of the reel 706 in the wrong space of the
rack 711; in this case the assembly of these elements must be made again .
Reassemble the lever 710 on the pin 733, with the marks ( __ __ ) aligned, (see picture page 19)
During the assembly phase of the support ( S ) on the turret, the screws 714 and 715 must be alternately screwed
in such a way to determine the support on the 2 tables (X) & (Y) (see picture on page 18).

Whenever the turret is disassembled, check the state of the following elements which will have to be replaced in
case of a negative result:
- 308 main gasket
- all retaining rings type (O-ring)
- 032 cushion pads
And the following elements (only when the central body has been completely disassembled):
- cam surfaces
- rollers
- HIRTH couplings
- all gears
- support plate of the 003 ring gear with the 002 one.
FROM THE TOP SIDE
Take off the 044 top cover, remove the screws 300, extract the 042 proximity support complete of proximity 301;
take off the 049 support complete of proximity 313, remove the 046a washers, extract the 200 electromagnet, extract
the 017 lock with related 047 spring.
Remove the 019 cover from the two sides, extract the 018 shock absorbing pins complete of 032 pads.
FROMTHE REARSIDE
Take off the 011 cover, remove the screws 302 and remove the 043 encoder support complete of 160 encoder, take
of the 303 seeger, remove the 030 thrust block and the 304 bearing.
FROMTHE FRONT SIDE
Take off the toolholder disk, remove the screws 305, take off the dowels 306. Move the push rod 700 towards outside
(Ú), extract the entire central body composed by 003 mobile ring gear, 005 indexing head, 006 roller carrier set,
007 spider set, 020 ring nut, 307 belleville washers, 025 - 026 spacers.
If dismounting this set too were necessary, unscrew the ring nut with a particular tool and extract all the other
components.

Assemble the parts as shown, then check that the value of U is between the ranges in the table below.
If it is not then grind a new distance piece 025 to it so that U falls within the ranges specified in the table.
Rollers on the high central
part of the cams
If any of the parts composing the central sub-assembly (except the satellite carrier 007), has to be substituted it
is necessary on reassemble to check and reset the distances T and U which determine the correct loading of the
spring.
Reassemble the parts, as shown in the figure, with the HIRTH teeth in contact and the rollers sitting on the raised
parts of the cams, check that the value of T is inside of the range indicated (0,2 - 0,25 mm).
If it is not then grind new races 023 to bring the value of T within the prescribed tolerance.

HINTS FOR
REASSEMBLE
DURINGCOMPLETEREASSEMBLE
- Insert the keys 309 into their corresponding key-ways (with identical marks) keeping the threaded holes turned
towards the ring nut 020 and in contact with the bottoms of the key-ways.
- Check that pinion 008 has a good sliding fit. If it does not, take it off and assemble it the other way with respect
to the keys.
- Check that the ring nut is thoroughly tightened. To make sure of this follow these instructions:
Before final assembly temporarily set aside parts 026 - 307 - 025, screw down the ring nut till it touches
its seating, measure the distance between the end of the divider 005 and the top surface of the ring, mark
the position of the ring nut in respect to the divider.
Lubricate O-ring 318 with heavy grease or vaseline.

After assembling all the parts add right amount of the correct type of lubricant to the carcase through the oil
hole (see page 25).

Then unscrew the ring nut, assemble the parts 026 - 307 - 025, screw on the ring nut, check that it reaches the same
position as before. Make this check by measuring the distance and observing that the marks coincide. Before
inserting the central sub-assembly into the carcase, rotate the satellite carrier 007 until the sealing of the latch is
in perpendicular position towards the coolant interception holes of the crown 002; insert the latch 017, rotate the
satellite carrier 007 by hand until the HIRTH teeth engage (rollers on the level parts of the cams). Release the latch.

The mechanical moving parts of the turret are permanently lubricated.
The lubricant must be renewed only after eventual complete dismantling of the turret.
The lubricant, with viscosity 80 SW 90, must be compatible with rubber & teflon.
The following table indicates the quantities to be used.
LUBRICATION OF THE ROTATING TOOLS MECHANISM
The mechanism of the rotating tools is lubricated with oil 80 SW 90. The oil must be changed every new re-assemble.
For this reason on the top of the 722 counterplate is located the hole for the filling.
Take off the airtight plug or the feeding pipe connector of the coolant, take off the spiral spring; then extract the bush
033 complete of O-Ring 322 by using a suitable thread X.
Clean the seating from any eventual incrustation, grease the outside part of the new bushes complete of O-ring, then
insert them in their seating and check the sliding.

SUBSTITUTION OF THE PRE-INDEXING ELECTROMAGNET
SUBSTITUTION OF THE BRAKE MAGNET
AND ADJUSTEMENT OF THE AIR GAP
Remove the rear cover 011, disconnect the leads connecting terminal block to the motor, the brake and the thermal
probes (heat sensor). Unscrew screws 311, extract the motor unit 150. Disassemble the gear 015 and remount it
on the new motor unit. Mount the motor unit in the carcase and reconnect the electric wiring to the terminal block.
To check that the phases are properly connected, perform a tool change by calling up the nearest station ... if the
phases are properly connected, the change of station will take place by the shortest route, if the disk goes the long
way round then interchange two motor supply wires at the terminal block (phase rotation).
Replace the rear cover.

Remove the rear cover 011, extract the motor unit 150 and the gear 015.
Disconnect the brake leads. Remove the defective brake magnet and substitute it with the new one.
Adjust the air gap (0,2 - 0,3 mm to be checked in a vertical position and acting on the distance pieces 090).
Reassemble the whole by following the above sequence in reverse.
Remove the top cover 044, remove the support 042, remove the washers 046a, extract the electromagnet 200.
Remove the rear cover 011 and disconnect the electromagnet supply leads.
Mount the new electromagnet in the carcase and fix it down with the two washers.
Replace the support complete with its proximity switch 301 and reset it (see page 28).
Connect the electromagnet lead wires to the terminal block (see electrical connection schemes page 11).
Replace top and rear cover.
