Mechanical Assembly Procedure (Continued):
35. Insert the detent ball (PN 02-0018) through the end of the detent tube attached to the top shifter bushing, followed by the detent
spring (PN 997-0-64) Thread a 7/16" UNF jam nut on to a 7/16" UNF x 1-1/4" hex bolt, and then thread the end of the bolt into
the detent tube on the top shifter bushing.
36. Insert two 5/16" x 3/4" production ground dowel pins into the top plate, one on either side of the motor shaft and gear cut-out,
directly behind the clutch assembly.
37. Position the motor mount (PN 1400-150) over the dowel pins and secure to the top plate using four 1/2" UNC x 2" hex socket
head cap screws.
38. Insert a 5/16" x 5/16" x 1-1/2" square key into the key slot on the motor shaft. Secure the motor gear (PN 997-A10-149) to the
hydraulic motor shaft using two 3/8" UNC x 3/8" flat point hex socket set screws. Ensure that the motor gear is oriented so that
the machined end of the motor gear (the end in which the set screws are threaded) is flush with the end of the motor shaft.
39. Mount hydraulic motor (PN 87-0110) to motor mount. Secure the RH side of the motor (as seen from the back of the tong) with
two 1/2" UNC x 1-1/4" hex socket head cap screws and 1/2" lock washers. The torque gauge holder weldment (PN 1500-09-04A)
is secured by the two LH motor screws - position the torque gauge holder weldment in place, and secure it and the LH side of
the motor with two 1/2" UNC x 1-1/2" hex socket head cap screws and 1/2" lock washers.
40. Attach the two #20 (1-1/4") x JIC 1" flange elbows (PN 02-9216) to the motor ports using two #20 split flange kits (PN 02-9217).
41. Attach the shifter lug weldment (PN 101-0016) to the top plate of the tong next to the top shifter bushing weldment using four
3/8" UNC x 1-1/4" hex bolts and 3/8" lock washers.
42. Connect the shifter handle weldment's (PN 1037-D-20B) pivot point to the pivot point of the shifter lug weldment using a 5/16"
x 1-1/2" clevis pin. Connect the end of the shifter handle weldment to the top of the shifter shaft using a 5/16" x 1" clevis pin.
Secure the clevis pins with .093" X 1.125" hitch pins.
43. Position the two top brake band lug weldments (RH Lug Weldment = PN 101-0132, LH Lug Weldment = PN 101-0134) on the
top plate over the holes for the support roller shafts as shown in the following illustration. Insert four "short" support roller shafts
(PN 101-3942) through the weldments and support roller components until the shoulders of the shafts are tight to the lug weld-
ments. Slide the two bottom brake band lug weldments (LH Lug Weldment = PN 101-0132, RH Lug Weldment = PN 101-0134)
over the bottom of the support roller shafts and secure with 7/8" UNF thin nylock nuts. ASSEMBLY NOTE: The support roller
assemblies coincidental with the brake band lug weldments DO NOT use flat washers.
