JAW SET MAINTENANCE
Pivot Group Adjustment Rev A
Maintain proper pivot group adjustment to optimize cutting performance and maximize the life of
the jaw set. Use the following procedure, along with the accompanying drawing, for initial set-up
and to make adjustments as the bearings wear.
1. Loosely assemble pivot group without end caps.
2. Set blade gap by pushing upper jaw blades against lower jaw blades with a 0.010” shim
between them.
3.
Ensure sleeve 1 is pressed tightly against upper jaw flange bearing 1. Measure the di
-
mension D1 and install shims to eliminate this gap. Fasten end cap 1 to the shaft on this
side.
4. Measure the dimension D2 and install appropriate shims.
5. Ensure end cap 1 is pressed tightly against the lower jaw and measure dimension D3.
Subtract D3 from 0.255” to determine the shim thickness required under the end cap.
Use a 3/8” dowel pin or a light film of grease to hold shims in place.
6. Tighten end cap 2. Verify a 0.005” clearance in the pivot group with a feeler gauge be-
tween the sleeve and the flange bearing on either side of the upper jaw.
7. Grease pivot group as described in this manual.
