Remove all O-rings of the chuck and the profile seals (item 66) at
the distributor ring. Wash all parts of the chuck with gaso-line
and blow out.
13 Check all O-rings and profile seals (item 66) for possible dam-
age and wear, replace them if necessary, and carefully rein-
stall them. Before the profile seals are inserted, it is recom-
mended that the profile seals (item 66) be rubbed with grease
by hand so that they remain elastic. There must be no visible
grease residue. When the profile seals (item 66) are reinsert-
ed, ensure that air passage openings do not align with the
pneumatic connections of the distributor ring.
14 The cylinder chamber of the chuck must be oiled. The jaw
guides in the chuck body, base jaws, and piston at the wedge
hooks are greased with LINOMAX grease.
Assembly
1 Insert the base jaws (item 2) in the guide shown, engage the
piston with O-rings (item 3) into the key teeth of the base jaws
and insert them as far as the end of the stroke.
Note: The piston wedge hook with the dot marking on the
inside is aligned using jaw guide 1.
2 Insert the O-ring (item 51) and the sealing disk with the O-ring
(item 5, 50) and tighten to the chuck body until firm and air-
tight using the 3 hexagon socket head screws (item 37) with
sealing rings (item 65).
3 Insert the guide bushing (item 4) from the front of the chuck
and secure with 3 hexagon socket head screws (item 36).
4 Push in piston cover with O-ring (6, 53) and ROTA TP 125-26,
ROTA TP 160-38, ROTA TP 200-52, ROTA TP 250-68, ROTA TP
315-90 (until 2014): Allow snap ring (40) to snap into the
recess without any problems. ROTA TP 125-26, ROTA TP 160-
38, ROTA TP 200-52, ROTA TP 250-68, ROTA TP 315-90 (from
2015): To fit the lock nut (40), use the assembly tool supplied
(pos. 80). Secure the nut with safety cord (33) (TP125) or
radially with copper bolt (33) and set screw (34) (rest). ROTA
TP 315-105, ROTA TP 350-115, ROTA TP-LH 315-105, ROTA
TP-LH 350-115: Mount screws (pos.40) and tighten them
