3.4.1 Jaw Availability
The following table lists all jaw die kits that are available as standard stocked sizes for this model of tong. McCoy
Global offers a good selection of standard jaw sizes. However, please note that we can custom-engineer and
manufacture any size of jaw within the range of the tong. Jaw systems are available to allow use of die inserts
intended for specialized applications. Call our sales office for information on jaw and die systems designed for
higher or lower grip, or non-marking applications.
The table lists standard contoured, flat and wraparound die inserts that are available as spare parts. However,
a wide variety of diamond-tooth, GRITFACE®, aluminium, and wrap-around fine-tooth dies are available for
specialized applications. Please refer to our website for complete information:

3.4.2 Tong Jaw/Jaw Die Installation and Removal
Worn jaw dies can usually be replaced without removing the tong jaws. Replacement of dies is simple and
straightforward, and may be performed on the drill floor in a few simple steps.
1. Remove hydraulic power from the tool. Although opening the tong door inhibits rotation, McCoy recommends
completely isolating the tool from hydraulic power in order to prevent accidental rotation in the event of
component failure.
2. Rotate the jaw towards pipe centre to fully expose jaw die keeper fasteners. NOTE: Die keeper fasteners my
be located on the bottom of the jaw, depending upon jaw orientation at installation.
3. Extract the keeper fasteners and, if required, use a hammer to tap the worn dies from the top or bottom
(depending on orientation) to remove.

DANGER

REPLACEMENT.

WARNING
NEVER ATTEMPT TO CLAMP ONTO TUBULARS WITH INCORRECTLY SIZED DIES. OPERATORS MUST
BE AWARE OF THE SIZE OF TUBULAR TO BE GRIPPED AND THAT THE JAW AND DIE SYSTEM IN
USE IS PROPERLY SIZED. USE OF INCORRECTLY SIZE DIES POSES A HAZARD TO PERSONNEL AND
EQUIPMENT.
