Place the seal so the open "V" portion is toward the head ring. You need to place the Figure 21 Figure 22 Figure 23 Figure 24 Figure 25 Figure 26 against the head ring. (See Figure 27 & 28) 3. Installing the low-pressure seal. You want the open side of the seal to be pointed toward the water side of the head (toward the high-pressure seal) and the flat side toward the drive end of the pump. Place the seal into the gland at an angle, with your finger push the exposed side of the seal towards the center and work the seal (See Figure 29, 30 & 31) into position. After the seal is in the gland you can work it into it proper position. 4. Install the retainer O-ring. (See Figure 32) Figure 28 Figure 29 Figure 30 Figure 31 Figure 32 NORTH AMERICA First Choice When Quality Matters Operating Instructions and Parts Manual RK Series Pumps Plunger Pumps Service Pumps (continued) 5. Squarely seat the retainer into the head and push with even pressure until it snaps 3. Twist and pull the plunger off the plunger rod. 4. Remove the plunger rod O-ring seal and split back-up ring with the into position. (See Figure 33) Servicing the Plungers Figure 33 Figure 36 mechanics pick. (See Figure 36 & 37) 5. Remove brass slinger. If the plungers are not damaged they do not need any servicing. Tools required: 16mm socket, ratchet, mechanics pick, taper blade gasket scraper, thread sealant and torque wrench. NOTE: Be very careful when working with the plungers, they are made from ceramic which is brittle and can be damaged. Any time you remove a plunger it is recommended you replace the slinger washer, O-ring and top plunger washer. The washers are a cushion for the ceramic plunger and compress when first used and the O-ring will take a set to create a seal and usually will not spring back to its original shape. By not replacing these parts you run the risk of breaking a plunger or having a water leak. Disassembly: 1. Remove the plunger retainer nut. (See At this point clean any thread locker that is left on the plunger rod and retaining nut threads. (See Figure 38) Assembly: 1. Install the slinger washer. (See Figure 39) 2. Install the plunger rod O-ring and split back-up ring. Place a light film of oil on the O ring and back-up ring. (See Figure 40) NOTE: The O-ring is closest to the threaded end of the rod. 3. Install the plunger by pushing straight down and twisting slightly in either direction (See Figure 41) Figure 37 Figure 38 Figure 39 Figure 40 Figure 34) 2. Insert the gasket scraper Figure 34 (NOTE: Be sure that the back-up ring is fully Figure 41 between the copper washer and plunger to remove the washer. (See Figure 35) Figure 35 seated). Make sure you fully seat the plunger. NORTH AMERICA First Choice When Quality Matters Operating Instructions and Parts Manual RK Series Pumps Plunger Pumps Service Pumps (continued) 4.

Refer to parts breakdown for oil type. of thread sealant in the thread. Install the plunger nut and tighten to the required torque. (See Figure 42 & 43) (See parts breakdown) Pump head to drive end Installation 1. Turn the crankshaft to align the plungers as shown. (See Figure 44) 2. Place the head evenly onto the plungers and push it until it makes contact with the drive end of the pump. (See Figure 45) 3. Torque the head bolt as shown in the tightening sequence diagram.
