separate cluster gear from driving gear, re
move ring (328B).
7.
Remove screw (248B, page 60) and loosen screw
(249B). Remove roll pin (250B). Tap shaft
(253B) from inside housing. As shaft is re
moved, it will force plug (254B) out of housing.
To Remove Overarm and Turret:
Styles 1-A, 1-B, 1-D and 1-E.
(See Pages 36 and 66.)
1. Attach rope sling through side openings in
motor housing in head and connect sling to
crane. Remove slack from sling. Remove
four nuts from T-bolts that hold head to over
arm and pull head straight out from overarm.
2. Remove coolant hose (27B, page 90) and brac
ket (23B) if machine is so equipped. Remove
socket head screw from top center of over
arm, insert an eyebolt and attach crane hook.
Wind overarm forward and slide out of turret
(257B, page 36). Make certain overarm is
balanced as it is slid off, to prevent damage
to ways. Break electrical connections, re
move four nuts (255B) from top of turret and
lift turret off column.
NOTE — The overarm is easier to balance while
removing if spindle housing is taken off first.
However, by using a rope sling around spindle
housing and from it to crane, it is possible to re
move overarm with housing in place.
To Remove Overarm ( Heavy Duty ): Style 1-C.
(See Page 42.)
Remove one 1/2" set screw (2B) from top of gear
housing (14B) on motor end, insert an eyebolt and
attach to a crane. Remove electrical compartment
cover (10B) and break electrical connections.
Wind overarm forward and slide out of turret.
Make certain overarm is balanced as it is slid
off, otherwise vee-way in turret may be damaged.
If a double swivel housing is being used, turn
spindle housing so it is in line with overarm to
prevent a twisting action as overarm is removed.
It is advisable to use two eyebolts in gear case
when lifting overarm with swivel housing in place.
To Remove and Dismantle Overarm Gear
Housing: Style 1-C
(See Pages 42, 44, 46)
1. Drain oil from gear housing. Set the center
and rear speed shift levers (74B, 68B,page 44)
in the number 2 stops and the forward lever
(88B) in either its number 1 or its neutral
stop. Remove twelve screws (5IB) and pull
speed control plate (56B)from overarm. Mark

location of gears so they can be more easily
set when assembling.
2. Remove two 1/2" set screws (2B, page 42),
insert two eyebolts and attach to a crane.
Through side opening, set couplings (109B,
112B, page 46) so
their sides are vertical, re
move fourteen screws (IB, 9B, page 42), and
raise gear housing out of overarm.
Overarm can be left on turret while gear
housing is removed but gear housing must be
in place to remove overarm.
3. Loosen set screw, tap to loosen lock shoe,
remove shoe-type lock nut (148B,page 46) and
drive spur gear shaft (142B) toward front of
housing sufficiently to expose set screw in
lock nut (144B). Loosen set screw and tap to
loosen lock shoe in nut. Tap shaft (142B) to
rear into original place and, using a spanner
wrench in the side holes of nut (144B), un
screw it. Tap shaft forward and out of hous
ing.
4. Remove shoe-type lock nut (137B), loosen
locknut (134B) until it is clear of shaft threads
and tap cluster shaft (13 IB) forward and out of
housing.
When assembling, set spur gear (132B) as
far toward rear of housing as possible so
change gear (145B) does not have to shift too
far forward to engage spur gear (132B). If
change gear (145B) moves too far forward, it
will rub against end of change gear shaft
(119B).
5. Remove coupling halves (109B, 112B) and hy-
pro keys from ends of change gear shafts
(105B, 119B). Remove shoe-type locknuts
(108B, 115B) and tap shafts out of housing.
The flange of bearing cup (106B) must have a
flat ground on one side to miss the adjacent
bearing.
To Remove Single Swivel Housing Spindle
and Drive —Without Hand Feed: Style 1-C
(See Pages 44 and 50)
1. Drain oil from gear housing. Set the two rear
speed change levers (74B, 68B, page 44) in the
Number 2 stop and the forward lever (88B) in
the Number 1 stop. Remove twelve screws
(51B) and pull speed control plate (56B) from
overarm. It is easier to align couplings when
assembling if speed control plate is off.
2. Unscrew four nuts (211B, page 50) and pull
spindle housing (213B) from overarm. Re
move index head gear (235B) from sleeve ad-
