VALVE SECTION

DISASSEMBLY

To remove manifold (42432-1) remove six (6) cap screws (Y154-57) and four (4) washers (Y14-10). NOTE: Springs (31125) and balls (44967) are loose parts and may drop out. To remove valve stem (40522) and spring (31125) remove pipe plug (Y227-2-L). NOTE: Gaskets (40524 and 45459) should be re- placed with new gaskets if manifold is removed from valve hous- ing.

To remove valve pistons and/or components from valve housing

(40511-1); remove screws (Y132-107-C) valve plates (40525-1) and gaskets (41222-1).

CAUTION: Exercise reasonable care when disassembling or as- sembling valve parts, so as not to cause damage to outside diam- eter of bushings, pistons. valves or bore diameters of bushings or housing.

Remove end pistons (41213) using a number 8-32 machine screw threaded into threads of piston. Pull out to remove. Tap end of housing lightly with a soft face hammer until bushing extends from housing enough to grasp with fingers and remove bushing with valve stem and other piston. Remove valve stem and piston from bushing.

Using a non-metallic rod (1/4” max. dia.), press spacer (41234) and other bushing, valve stem and piston out opposite end of housing. NOTE: Replace all “0” rings with new “0” rings when reassembling.

To remove actuator and pin assembly; remove springs (39452) move actuator to the extreme left and remove valve stem (40522) from left side of housing. Slide actuator to extreme right and re- move othervalve stem (40522) from that end of housing. Actuator and pin assembly can now be removed from housing. To remove trip tabs; remove retaining ring (Y145-18) from actuator, loosen screw (45457) and slide trip tab off actuator.

To remove screen (41266) remove screws (Y8-243-C) and plate (41246-1).

REASSEMBLY

It is recommended “0” rings be replaced with new “0” rings when reassembling. Lubricate all “0” rings with 36460 lubricant and coat pistons and valve stems with 29665 spindle oil when assem- bling.

Assemble valve stem (40522) with “0” ring (Y325-7) and spring (31125) to manifold and secure with pipe plug (Y227-2-L). As- semble balls (44967) and springs (31125) to manifold. Assemble “0” rings (Y325-14) to manifold.

Assemble “0” rings (Y325-17) to spacer (41234) and assemble to housing with large hole in spacer facing towards front end of housing (see cross section below).

Assemble “0” rings (40284 and Y325-17) to bushings (41214-1 and 41215). Assemble “0” rings (Y325-15) to pistons (41213). Assemble “0” rings (15066) to valve (41217-1).

Assemble valve (41217-1) and pistons (41213) to bushing (41214-1) and assemble bushing to housing. NOTE: See cross section view below for correct installed position of bushing, piston and valve stem.

Assemble valve stem (41216) and pistons (41213) to bushing (41215) and assemble bushing to housing, NOTE: Align slots in bushing with exhaust holes in housing as shown in auxiliary view on page 11. Assemble pistons as shown in cross section view be- low.

Assemble trip tabs (40523-1), with spacers (41572), to actuator (see correct assembled position below) and secure with screws (45457). Assemble retaining rings (Y 145-18) to actuator. Position actuator in housing and assemble valves (40522) with “0” rings (Y325-7) to housing and pins of actuator, securing actuator in housing.

Assemble springs (39452) gaskets (41222-1) spacer (46496) and valve plates (40525-1) to housing and secure with screws

(Y132-1074). NOTE: Torque screws to 45 - 55 in. Ibs.

When assembling the valve section to tool, be sure bracket (41235) page 17, is positioned between the two trip tabs and air tubes are properly aligned. Secure valve section to spindle hous- ing with cap screws (Y 154-54) and washers (Y14-10).
