SPINDLE LOADS AND HYDRAULIC PRESSURES AT SHIFT FOR HUCK MODEL 200 INSTALLATION TOOL
When used to install double action fasteners, the shift valve of the Model 200 H.I.T. must be adjusted to
insure the proper installation of various fasteners. Two methods of checking the shift valve setting are
available:
Method #1: Shift Setting Kit No. 107569 employs a Skidmore-Wilhelm Tension Tester to check the spindle
load at shift, in pounds.
Method #2: Shift setting No. 101300 employs a hydraulic pressure gauge to check the hydraulic pressure
at shift, in pounds per square inch (psi).
The chart below shows the “Spindle Load at Shift” and “Hydraulic Pressure at Shift” for various fas
teners. It
may be necessary to retrofit some older tools prior to serial number 5161 (except 5081 thru 5090
and 5120 thru 5135), using Shift Valve and Balance Valve Retrofit Kit No. 100434, to insure
repeatability of the shift valvesettings.
(1) Set as close as possible to pounds or psi shown.
(2) Plus or minus 50 psi, unless otherwise specified.
