Remove 10-32 screw from the Linear Transducer rod
|
Remove 10-23 screws from the Linear Transducer bracket
and remove the Linear Transducer Assembly from the pump.
|
Remove four ¼-20 SHCS that connect the Top Plate
to the four Linear Shafts. |
Remove the two 5/16-24 SHCS that connect the Top Plate
to the two LDP Rods.
|
Remove the Top Plate and set aside. |
Remove four ¼-20 SHCS connecting Upper Cylinders
to the Center Plate.
|
Remove the Upper Cylinder Set and set aside. |
Remove two 5/16-24 SHCS that connect the Center Plate
to the two LDP Rods.
|
Attach tie raps to the Ball Screw above the Ball Nut and below
the Center Plate. (This prevents the Ball Screw from
accidentally unwinding out of the Ball Nut) |
Lift the Center Plate Ball Screw Assembly off
the Linear Shafts and set aside.
|
Remove four ¼-20 SHCS connecting the
Bottom Plate to the Bottom Cylinder Set. |
Remove the Bottom Cylinder Set and set aside.

Mount the Cylinder Assembly in the LDP Cylinder Clamping Fixture. Use a 1 3/4 socket to loosen the LDP Cylinder Nuts.
(The Clamping Fixture provides maximum holding power
without imparting stress to the welded Cylinder Manifold joints.
If the welded interfaces are broken, the assembly
cannot be repaired) |
Remove the Cylinder Nuts with LDP Rods inserted.
Be careful not to ding or scratch the Rods.
|
Carefully remove the LDP Rods from the Nut.
(Scratches or dings on the Rod surface can cause short seal life)
|
Remove the old Seals from the Nuts taking care not
to damage the plastic Rod Bearing surface.
|
| Clean the Cylinder Nuts and LDP Rods of any resin/catalyst residues. Care should be taken not to scratch or dent the LDP Rod surface. Soft tools made of plastic, wood, or soft abrasives (such as 3M Scotch Brite) are safe. For heavy tenacious residues, soaking parts overnight in chemical strippers will dissolve or soften the polymeric residues. |
