Repair

Disassembly

Lay out all the removed parts in sequence, to ease reassembly. Clean all parts with a compatible solvent and inspect them for wear or damage. Refer to F

Repair Kits are available to replace the throat (T) and piston (P) packings, and to replace the o-rings and cylinder seals. For the best results, use all the new parts in the kit. Kit parts are marked with an asterisk, for example (11*). These kits also can be used to convert the lower to different packing materials. Refer to pages 16-20.

1. Flush the pump, if possible. Stop the pump at the bottom of its stroke. Relieve the pressure, page 6.

2. Disconnect the lower from the motor. See your separate pump assembly manual.

3. Stand the lower upright in a large vise. Loosen, but do not remove, the packing nut (3). Remove the six long cap screws (20).

4. Lift the outlet housing (19) straight up off the lower. Be careful not to scratch the displacement rod (1) while removing the housing.

5. Lift the cylinder (7), displacement rod (1), and piston assembly off the intake housing (17).

IG. 1.

9. Stand the cylinder (7) upright on a wooden block. Using a rubber mallet or an arbor press, drive the displacement rod (1) and piston assembly down into the cylinder as far as possible, then place the cylinder on its side and continue to drive the rod out the bottom until the piston comes free. Pull the rod and piston from the cylinder, being careful not to scratch the rod or cylinder.

• For Dura-Flo 1800 (430 cc) Lowers, order Part No. 109507 Tool.
