5. Install the retainer O-ring. 6. Squarely seat
the retainer into the head and push with even pressure until it snaps into position. (See Figure 25)
SERVICING THE PLUNGERS If the plungers are not damaged they do not need any servicing. Tools required: 13mm 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 fi rst 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 Figure 26)
2. Insert the gasket scraper
between the copper washer and plunger to remove the washer. (See Figure 27)
3. Twist and pull the
plunger off the plunger rod. (See Figure 28)
4. Remove the plunger
rod O-ring seal with the mechanics pick.
5. Remove the brass slinger. At this
point clean any thread locker that is left on the plunger rod and retaining nut threads.
ASSEMBLY 1. Install the brass slinger washer. 2. Install the plunger rod O-ring.
Place a light fi lm of oil on the O-ring.
3. Install the plunger by
pushing straight down and twisting slightly in either direction. Make sure you fully seat the plunger. (See Figure 29)
4. Install the small copper
washer on top of the plunger and place a small quantity of thread sealant in the thread. Install the plunger nut and tighten to the required torque. (See Figure 30)
(See Table D or
parts breakdown)
PUMP HEAD TO DRIVE END INSTALLATION 1. Turn the crankshaft to
align the plungers as shown. (See Figure 31)
