NOTE ON INSTALLATION PRACTICES: Ensure all bearings are liberally greased before installing over a shaft or into
gears or bearing caps. When inserting a shaft through a support roller assembly ensure shaft is greased. Also ensure
all metal-to-metal contact in the gear train is adequately greased.
When graphics are not used in the assembly process,
please refer to the relevant exploded diagrams in Section 5.
1. Position the tong body gear case on a suitable stationary support such that the bottom body plate is accessible.
2. Assemble ten support roller “dumbbell” assemblies:
• Insert an inner support roller spacer (PN 1064-183) into each dumbbell support roller (PN 1064-181).
• Press a support roller bearing (PN 02-0099) into each end of the dumbbell rollers.
• Slide a support roller bearing spacer (PN 1064-182) over each support roller shaft ( 5 x PN 101-3942, 4 x PN 101-3944,
1 x PN 101-3943).
• Insert a support roller shaft through completely through each dumbbell assembly.
3. Place four support roller assemblies along one side of the cage plate opening.
4. Install rotary gear (PN 1064-D1), making sure the backing pin slots are on the side facing up. Ensure one side is sup-
ported by the support rollers installed in Step 3, and the opening in the rotary gear is oriented toward an open support
roller space as shown in the following illustration.
