HYDRAULICS 1.103 Inlet section (PVSP) (36) General Assembly The main components of the inlet section (PVSP) are the main body compensator spool, steering priority spool and an external BAC valve. Dismantling and assembly of the section is limited to these components. Assemble the inlet section (PVSP) in the reverse order to dismantling. Take care not to not to damage the main body when installing the components. Torque tighten the components as follows: Dismantling BAC valve (3) - 40 ± 3 Nm (350 ± 26 lbf/ft.) 1. Remove the check valve (1) from the main body (2), with an Allen key, complete with O-ring seals. Adapter (4) - 40 ± 3 Nm (350 ± 26 lbf/in.) 2.
Remove the BAC valve (3) and O-rings from the main body (2). Plug (7) - 40 ± 3 Nm (350 ± 26 lbf/in.) Check valve (1) - 40 ± 3 Nm (350 ± 26 lbf/in.) 3. Unscrew the LS adapter (4) from the main body (3), remove O-ring (5) and compensator spring (6). 4. Unscrew the plug (7) from the compensator spool on the main body (2). 5. Clean the main body in an approved solvent and dry using an air jet, do not use cloths or paper wipes. 6. Clean the BAC valve, check valve and compensator in an approved solvent and dry using an air jet, do not use cloths or paper wipes. 7. Examine the main body for wear, burrs, blocked grooves or other damage.
