Disassembly

Reassembly

Overhaul

Overhaul consists of disassembling the tong, examining each part,

replacing any worn or damaged parts and then reassembling the tong.

All damaged or worn parts are to be replaced with identical parts as

identified in "Tong Disassembly and Parts" (Section 8).

Disassemble the tong only to the extent required for necessary part

replacement and/or overhaul. To disassemble the tong, follow the
exploded illustrations in the illustrated parts lists (Section 8).

Reassemble the component parts in the reverse order of disassembly.

Service and adjust according to the maintenance instructions and test

according to testing procedures.
