Section 8
and Parts
The Model 16 tong is designed for assembly/disassembly using normally available
mechanics' tools. No special tools are required. As with any piece of equipment, the
mechanic must familiarize himself with the equipment and nomenclature to avoid improper
assembly and damage to the tong. Do not disassemble the tong or subassembly further than
necessary to accomplish the required maintenance.
WARNING: Do not attempt to perform any adjustment, repair or disassembly with
the tong connected to a power source.
The Model 16 tong has been separated into several major subassemblies as listed below.

Disassembly
Rotary Assembly
WARNING: Jaws must be removed prior to rotary disassembly.
Rotary Removal
This procedure applies to both the 13 3/8 inch rotary assemblies.
Remove the three rotary retainer bolts from the underside of the case and doors. Place
the tong on a flat surface, where it cannot tilt forward when doors are opened and the rotary
is slid forward.
WARNING: Do not allow doors to open as rotary may slide out if case is tilted
while being positioned.
Open doors fully. Fasten rotary plunger assembly (112414-001) in the down position and
slide rotary forward until rear section is clear of case body. Attach sling, take up slack and
slowly slide the rotary forward and out of case. Maintain support on front of rotary to
prevent tilting (see Figure 8-1). Place rotary on blocks to allow access to underside.
