Control (193/260)
Removal
1. Remove the control from the endcap by removing the mounting bolts (See
Control seal type and
mounting bolts
). If the control has the TC/DC feedback link (D640), ensure that it does not stay in the
hole of the bias piston in the endcap, remove it and place it with the control.
2. Remove and discard the seals (See
Control seal type and mounting bolts
) .
Installation
1. Install new seals (See table
Control seal type and mounting bolts
). Proper gasket alignment is dictated
by alignment pins in the control housing. For O-rings, lightly lubricate them prior to assembly.
2. If the control uses a TC/DC feedback link, make sure that it is set in the bias piston hole, then install
the control housing assembly onto the endcap using the mounting bolts.
