3.9.2 Suction Manifold
The suction manifold (3) bolts to each cylinder block and seal the flange connection face through the
0-ring. Thoroughly clean o-ring groove, the 0-ring sealing surface at bottom of the cylinder block. Put
o-ring in before bolting suction manifold into position; the flange connection MUST make up
metal-to-metal to ensure the o-ring seal, therefore any nicks, grooves or washouts on the sealing
surface must be repaired before installation. Ref. Welding and Repair Section (3.10) in this manual for
repair procedures.
Screw the three cylinder blocks bolts (loose and no fasten) before tightening suction manifold bolts
(5), and then tighten with torque values shown in table 6.
3.9.3 Discharge Manifold
The discharge manifold bolts to each cylinder block and is sealed through the 0-ring in the connection
flange. Thoroughly clean the 0-ring groove, the 0-ring sealing surface on face of the cylinder block
before bolting the manifold into position. The flange connection MUST make up metal-to-metal to
retain the 0-ring seal; therefore any nicks, grooves, or washouts on this sealing surface must be
repaired before installation. Ref. Welding and Repair Section 3.10 in this manual for repair procedures.
Screw the three cylinder blocks bolts (8) (loose and no fasten) before tightening discharge manifold
bolts (5), and then tighten the connecting bolts of cylinder and frame with torque wrench values
shown in table 6.
