5.3 Body and Clamp Re-Assembly
1. Place the metal reinforced seal on lower filter body.
(Fig 4) Place upper filter body on metal reinforced
seal and lower filter body in a position which allows
all operation and safety labels to be clearly visible
and the upper filter body to be centered on the lower
filter body. Press down firmly and evenly on the upper filter body to seat the seal. (Fig 7)
2. Replace the filter clamp around the upper and lower filter bodies. Hold the clamp ends to position
the clamp on the filter bodies with the clamp ends adjacent to the safety and operation labels on
the filter bodies. (Fig 7)
3. Insert clamp bolt through the clamp ends and thread the clamp nut onto clamp bolt with
rounded end of the nut (Fig 8) towards the ends of the clamp.
4. Never rely on hand tightening of clamp nut to clamp bolt. Using a 3/4" socket on a torque
wrench, torque clamp nut to clamp bolt to 150 inch-lbs. (Fig 9)
