Motor
If bearings items 4 and 13 in the end plates items 3 and 12 were replaced, the spacing of
the motor has to be redone. For that, new spacers items 6 and 15 are used. Press bearings in
the end plates backlash-free in direction to snap ring in order to find out dimension of spacer.
The end play between rotor and end plates should be approx. 0.04 mm per side, to ensure free
running of the rotor.
Make functional gauging of motor with handle by checking free speed (approx. 15,000 rpm
at an operating pressure of 6 bar).
Gearbox head
Build-in lift rod item 5 in correct position. Check the complete assembled bevel gear item 24
with bearings and bolts for easy running. Attach roller holder item 124 completely.
Test roller guide for easy movement. Screw together gear part 1 and gear part 2 and pull
over protective cover. Screw components „Motor with Handle " and „ Gearbox head".
Fill the gear with grease, e.g. Calypsol-D8024 (approx. 80 g).
After completion of re-assembly make following functional gauging: Cutting capacity, Power,
start reaction
Replacement of Vanes
For replacing the main wear parts (the vanes) proceed as follows:
Disconnect air hose from handle. After loosening screws item 27 of gearbox, take off motor
with handle.
Remove pinion item 20 from rotor journal. Screw out motor cover item 17. Draw out rotor
item 10 with end plate item 12 and vanes item 11. Tapping with a rubber mallet onto edge of the
motor housing item 1 is helpful. Doing that, also cylinder bushing item 7 with rear end plate item
3 can be drawn out.
CAUTION! Do not cant/ Never use force!
Change vanes item 11, clean rotor slots, check surfaces and smooth them, if necessary.
Push cylinder bushing item 7 into housing. Take care for correct position. Put in spacers
item 6 again, looking for that the inner chamfer as well as spacer item 15 point to the rotor.
Insert rotor item 10 with the new vanes item11 and spacer item 15. Install end plate item 12 with
bearing.
Put in O-ring item 16 and fasten motor cover with screws. Now rotor has to be turned easily.
If not, light tapping with a rubber mallet straight or lateral on motor housing is helpful to put
the rotor in free-wheel position. Thereupon mount the pinion item 20 and screw on gearbox.
Connect air hose and perform functional gauging.
Replace wear parts – in particular the vanes – when necessary.
Vanes are considered worn, if their width is less than 9.5 mm.
Original (new) 10,5mm
Worn (replace)<9,5mm
