Long bottom-loading to a long top-loading conversion:
1. Secure the pump with a spanner wrench “A” on the head or with a screwdriver “B”
through the support ring.
(See Figure 52)
2. Unthread discharge check valve “C” from the pump and clean the threads in the
valve and on the pump “D”. A strap or pipe wrench can be used.
3. Apply Teflon tape to the threads on the wye assembly nipple “E” and thread on
the discharge check valve. Check that the pinned end of the valve is up. Hold the
bushing at the top of the "WYE" with a wrench and then tighten the valve with a pipe
wrench or a strap wrench.
4. Apply Teflon tape to the pump threads “D”. Tighten the wye assembly on the
pump by using a wrench on the bushing at the bottom of the "WYE". Align the
"WYE" so that the air ports on the pump head are even with the indentations on
each side of the "WYE".
5. Remove the bottom check valve “F” with a spanner wrench. If the casing comes
off with the valve, the valve may be knocked out with a wooden “2x2” or similar
blunt tool, inserted into the open end of the casing.
6. Remove the o-ring from the valve and install it on the bottom plug “G”.
7. Lubricate the first 3/4 in. of the inside with food-grade Teflon-filled grease.
8. Spin the bottom plug on the pump with a spanner wrench, or, with a screwdriver
through the hole. Do not use sealant or tape.
Caution:
Turn the plug only until each end of the casing is just touching the
head and the plug, and then back it off 1/4 turn. Do not tighten the parts
hard against each other.
If the casing is off the pump, insert the plug until the o-ring is against the edge of the
casing. Then hold the casing vertical and place the open end against a resilient surface, like
rubber, cardboard, or carpet. Press the plug downward into the casing. Spin the casing on
the pump with a spanner wrench, screwdriver, or with a strap wrench on the last 1-1/2-inch
of the casing.
Warning:
Keep hands away from the pinch point while pressing the plug into the
casing
