OTOR SSEMBLY
Caution! Caution!
To prevent damage to the sealing and O-rings, grease
them prior to assembly with grease (Order No. 914392).
Be sure to assemble the parts in the sequence shown on
the spare parts drawing.
- Press rotor cover <41> with ball bearing <40> on rotor <46> with
fixture <D> (8. Assembly Instructions, fig. 7 + 8)
- Mount air distributor <39> onto rotor.
- Assemble seal ring <34> in shut-off piston <33>.
- Slide shut-off ram <37> into rotor (assembly device) and put both
completely into device <G> (fig. 10)
- Install actuating bolt <36> and balls <44>.
- Fit compression spring <35> in drilling.
- Fasten pre-assembled shut-off piston <33> to rotor.
- Lift rotor completely (without shut-off ram <37>) from assembly
device. The shut-off piston is interlocked with the rotor.
- Assemble centrifugal force controller <32> - <26> (7. Spare Parts
Exploded View)
- Place O-Ring <38> behind pin in pistol housing.
- Insert the pre-assembled parts in the pistol housing. To do so the
slot at the periphery of the air distributor <39> must be adjusted
concentric to the reverse button groove to enable a setting with the
pin.
- Assemble reverse button <14> and countersunk screw <15>.
- Insert rotor cylinder <43> with shear keys <42> into pistol grip
housing.
- Insert the blades <45> into the rotor grooves of <46>.
- Put the ball bearing <48>, the shim ring <49> and the circlip <50>
into the rotor cover <47> and mount all into the pistol grip housing.
- Assemble sleeve <51>
- Slide shut-off ram <37> back into the rotor
Do only switch on motor when pulse unit <55> and housing
<91> are assembled
Caution! Caution!
When installing the screen <8>/<11>, be sure the circlip
<9>/<12> is lying flat on the screen.

ULSE NIT ISASSEMBLY
Allowed only if filling with oil filling unit <A> can be
guaranteed. The pulse unit must have cooled down to
room temperature.
Caution! Caution!
Be sure retaining rings <93> and <98> are not extended
excessively
- Remove first parts <98> - <92>
- Pull housing <91> off pulse unit.
- Fix fixture <C1> in vice and insert pulse unit in fixture at motor input
slot (8. Assembly Instructions, fig. 1).
To avoid endangering health or environment, always
comply with the local regulations for security and prevention
of accidents.
Avoid direct skin contact when working with oil to prevent
skin irritations.
- Remove set bolt <79>. Remove ball <78> by turning the drive shaft
<73>, keeping the opening away from the body.
- Loosen the bearing ring <77> with the device <C2>.
- Remove the bearing ring above an oil pan and pull the hydraulic
rotor <73> from the housing.
Hydraulic roller is spring-loaded!
- By removing the needle roller <87> all parts built in the hydraulic
rotor can be removed.
- Clean all parts.
Caution! Caution!
Always only use original spares from CLECO. Use of
foreign spares entitles the manufacturer of the tool to void
the warranty.

SSEMBLY OF THE
Caution! Caution!
To prevent damage to the sealing and O-rings, grease
them prior to assembly with grease (Order No. 914392).
- Reassemble by reversing the disassemby process as shown
(7. Spare parts exploded view).
- Push parts <62> - <57> onto the hydraulic cylinder <63> and
secure them with the circlip <56>
- Assemble o-ring <67> and o-ring <75> on hydraulic rotor <73>.
- Install O-ring <66>, needle roller <65> and sleeve <100> in
hydraulic rotor.
- Push fixture <E> over long side of shaft on hydraulic rotor
(8. Assembly instructions, fig. 2).
- Insert compression springs and blades over the slots of fixture <E>
by pressing them down and turning the hydraulic rotor into the
hydraulic rotor slots (fig. 3).
- Adjust control blade <72> (with long shaft end) towards bore in
fixture (fig. 4).
- Install needle roller <64> in hydraulic cylinder.
- Using <E> slide the hydraulic rotor into hydraulic cyclinder <63> so
that the fastening groove of <E> matches needle roller <64>
(fig. 5).
- Remove <E>.
- Mount disc <74> and positon over needle roll.
Caution! Caution!
The control slides at the facing surface of the disk points
towards the slots in the rotor
- Put up bearing ring <77> with o-ring <76>.
- Insert pulse unit <55> into fixture <C1>.
- Tighten bearing ring by means of fixture <C2> until the limit stop.
- Undo the bearing ring by 270° +90° and carry out the oil filling:
