7. Pull the handwheel screw assembly (key 145) out of the handwheel body. The operating nut (key 132) will come
out with the screw. Also remove the bushing (key 151, figure 16 or 17) on size 34 and 40.
8. If required, remove the two ball bearings (key 152), one from the bearing retainer and the other from the
handwheel body.

on a 667 actuator.
1. Pack the ball bearings (key 152) with anti-seize lubricant (key 244). Insert one bearing and the bushing (key 151,
figure 16 or 17) into the handwheel body (key 142). The bushing is not used in a handwheel assembly for sizes
45/45i through 60/60i actuators.
2. Coat the handwheel screw assembly (key 145) threads with anti-seize lubricant (key244), and thread the operating
nut (key 132) onto the screw. Slide the second ball bearing (key 152) onto the screw, and insert the end of the
screw into either the bushing (key 151, figure 16 or 17) for sizes 34/34i and 40/40i, or into the bearing for sizes
45/45i through 60/60i.
3. Thread the bearing retainer (key 136) into the body (key 142). Completely tighten the bearing retainer, and then
loosen it one-quarter turn. Tighten the set screw (key 168, figure 16 or 17) to hold the bearing retainer in place.
4. Coat the groove in the handwheel body (key 142) with lithium grease (key 241). Insert the spring (key 56) and ball
(key 55) into the handwheel (key 51). Holding the ball and spring in the handwheel, put the handwheel, the washer
(key 149), the lockwasher (key 150), and the stop nut (key 54) onto the end of the end of the handwheel screw (key
145). Tighten the stop nut.
5. Position the pointer mounting bolt (key 159, not shown) and pointer (key 160). Insert and tighten the screw (key
161).
6. Assemble the two levers (key 146) with the cap screws (key 156) for handwheel assemblies for sizes 45/45i, 50/50i,
and 60/60i actuators, or with the machine screws (key 156) for handwheel assemblies on sizes 34/34i and 40/40i
actuators.
7. Use step a. for size 34 through size 60 actuators, and use step b. for sizes 34i through 60i.
a. For Size 34 through 60: If the handwheel assembly was removed from the yoke (key 9, figures 6, 8, or 10),
remount the handjack assembly to the yoke using the dowel pins for alignment. For the size 34 and size 40,
position the U-bolts and J-bolts (keys 166 and 143) on the yoke, and hand-tighten the hex nuts (keys 170 and
147) to hold the handwheel assembly in position. For the size 45 through size 60, position the U-bolts (keys 166
and 143) on the yoke, and hand-tighten the hex nuts (keys 170 and 144) to hold the handwheel assembly in
position. Cap screws (key 163) should be tight against the yoke legs to provide stability. Tighten the nuts (key
144 for size 30 and size 40, key 158 for the size 45 through size 60). For the size 34 and size 40 finish tightening
the U-bolt nuts to 81 N•m [60lbf•ft] (key170) and 41 N•m [30 lbf•ft] (key 147). For the sizes 45 through 60
finish tightening the U-bolt nuts to 163 N•m [120lbf•ft] (key170) and 41 N•m [30 lbf•ft] (key 144). Be sure the
handwheel assembly remains flat against the mounting pad and perpendicular to the yoke.
b. For Size 34i through 60i: If the handwheel assembly was removed from the yoke (key 9, figures 7, 9, or 10),
remount the handjack assembly to the yoke using the dowel pins for alignment. Position the upper cap screws
(key 256) on the assembly and hand-tighten to hold the handwheel assembly in position. Place the spacers (key
258) between the yoke and handjack assembly, position cap screws (key 257), and hand-tighten. For the size
34i and size 40i finish tightening the cap screws (key 256) to 92 N•m [68 lbf•ft] and (key 257) to 39 N•m [29
lbf•ft]. For the sizes 45i through 60i finish tightening the cap screws (key 256) to 163 N•m [120 lbf•ft] and (key
257)to 39 N•m [29 lbf•ft].
8. Position the levers (key 146) as shown in figures 11 or 12. Insert the lever pivot pin (key 153), and snap the retaining
ring (key 154) onto the lever pivot pin.
