Apply even pressure to the bearing race that will be press
fitted to the mating part.
Use correct tools and fixtures when servicing this tool.
Don't damage "0" rings when servicing this tool.
Use only genuine ARO replacement parts for this tool. When
ordering, specify part number, description, tool model number
and serial number.
DRIVE GEARING DISASSEMBLY
Clamp tool in a smooth face vise, clamping on housing (16).
Place a wrench on adapter body (64) and strike wrench a
sharp blow to loosen adapter body.
Remove adapter body (64) and spacer (62).
Using wrenches on flats of nose housing (60) and ring gear
(46) unthread and remove drive gearing.
Remove nose housing (60) and seal (59) from ring gear.
Grasp ring gear (58) in one hand and tap threaded end of
spindle (53) with a soft face hammer; spindle and components
will loosen from ring gear.
Do not disassemble further unless damage is evident, as Brin-
elling of the bearing races may occur, making replacement
necessary.
To disassemble, remove bearing (55).
Turn snap ring (54) so the open portion allows removal of shaft
(50).
Remove shaft (50) releasing gear (52).
Repeat for removal of opposite shaft and gear.
Place shafts (50) into spindle and alternately tap ends to re-
move bearing (49).
DRIVE GEARING ASSEMBLY
Assemble snap ring (54) to groove in spindle, aligning open
portion of snap ring with hole for shaft.
Lubricate needle bearings (51) with ARO 33153 grease and
assemble to gears (52).
Lubricate gears (52) liberally with ARO 33153 grease and as-
semble one gear to spindle, securing with shaft (56).
Repeat for opposite shaft and gear.
After assembly of gears and shafts, turn snap ring so open
portion is approximately 90° from either shaft.
Assemble bearing (55) to spindle, pressing on inner race of
bearing.
Pack bearing (49) with ARO 33153 grease and assemble to
spindle, pressing on inner race of bearing.
Assemble washer (57) wave washer (56) and spindle and
components into ring gear (58).
Assemble seal (59) and nose housing (60) to ring gear (56).
Assemble drive gearing to tool and tighten, using wrenches
on flats of nose housing (68) and ring gear (46).
Assemble spacer (62) and adapter body (64) to spindle.
Assemble locking pin (65) to adapter body (64) securing with
rubber insert (66).
AUXILIARY GEARING DISASSEMBLY
Remove drive gearing from tool.
Using a wrench on flats of lock nut (37) loosen lock nut and
remove auxiliary gearing from tool.
Grasp ring gear in one hand and tap drive end of spindle with a
soft face hammer; spindle and components will loosen from
ring gear.
Do not disassemble further unless damage is evident, as Brin-
elling of the bearing races may occur, making replacement
necessary.
To disassemble, remove bearing (44).
Turn snap ring (43) so the open portion allows the removal of
shaft (39).
Remove shaft (39). releasing gear (41).
Repeat for removal of opposite shaft and gear.
Place shafts (39) into spindle and alternately tap ends to re-
move bearing (38).
AUXILIARY GEARING ASSEMBLY
Assemble snap ring (43) to groove in spindle, aligning open
portion of snap ring with hole for shaft,
Lubricate needle bearings (40) with ARO 33153 grease and
assemble to gears (41).
Lubricate gears liberally with ARO 33153 grease and as-
semble one gear to spindle, securing with shaft (39).
Repeat for opposite shaft and gear.
After assembly of gears and shafts, turn snap ring so open
portion is approximately 90° from either shaft.
Pack bearings (44 and 38) with ARO 33153 grease and as-
semble to spindle, pressing on inner race of bearings.
Assemble spindle and components into ring gear.
Thread lock nut (37) all the way onto ring gear.
Assemble auxiliary gearing to tool and tighten, using a wrench
on flats of ring gear.
Tighten lock nut (37) against housing (16) securing auxiliary
gearing.
Assemble drive gearing to tool.
