Seal Replacement
After approximately every 1000 hours of use, the watermaker should be partially disassembled,
cleaned, and lubricated with non-petroleum silicone grease. At that time, the seals should be
inspected and replaced, as required. The standard Repair Seal Kit (included in the Extended Cruising
Kit (see Kits and Accessories) is available from Katadyn and most marine retail stores. It includes a
complete set of replacement seals and other components for all user-serviceable parts of the
watermaker.
It is unlikely that you will have to replace all of the seals contained in the kit at every servicing. The
dynamic seals work harder and wear faster than others, and will need to be replaced more often.
We recommend that you save old seals. Most of them are still useable and could be kept in a kit for
emergency repairs.
Preparation :
Before beginning to disassemble the watermaker, read the following instructions
completely. Have a Repair Seal Kit on hand. Refer to the drawings in Figures A-2 , A-3 and A-4 in
the Appendix to identify the major components of the pump and the parts contained in the kit to
make sure none are missing. Prepare a clean flat workspace with good lighting. Have the following
tools and materials available for a complete rebuild:
Tools Needed:
piston seal installation tool small scissors
1/2 “ open-end wrench 10x loupe or magnifier
5/8 “ open-end wrench silicone grease (included in Repair Seal Kit )
1/4 “ allen wrench clean rags
medium flat blade screwdriver small standard pliers
Disassembly :
1.
Before beginning disassembly, run the watermaker and stop it when the piston shaft is at its
farthest point of travel away from the pump (i.e., toward the drive assembly). This provides
enough room for sliding the rubber boot toward the pump in Step 3.
2. Disconnect the pump from the drive assembly by first removing the two hex nuts and 5"
socket head cap screws from the check valve plate, using the 1/2" open-end wrench and
1/4" allen wrench. Also remove the two hex nuts securing the pump back plate to the drive
assembly. See
Figure R-1
.
3. Slide the black rubber boot on
the piston shaft toward the
pump to expose the drive shaft
coupling pin. Use a small allen
wrench or similar tool to push
the coupling pin out of the
drive shaft (see
Figure 6 ). Be
aware that the coupling pin
fits loosely in the drive shaft
and may fall out when the
rubber boot is removed. Be
careful not to lose it. Separate
the drive assembly from the
