Servicing Tank Suction Valves & Gaskets
1. Empty tank of (all) material inside (elevate front of
truck if possible to make sure you get it as empty as
possible)
2. Elevate Rear of truck if possible as a safety measure
(any left- over material will flow to front of tank)
3. Open Fill-line cap / Activate and open Tank Valve
and make sure Tank is empty before removing Valve
4 Open Strainer Box lid and inspect valve for other
issues (Broken Spring / missing snap ring etc)
5. Activate and open Tank Valve before removing the
(8) bolts attaching the Tank Valve to the Strainer Box
6. Remove Tank Valve slightly about 2 inches / then
allow Tank Valve to close releasing spring tension.
7. Mark to identify & remove air lines, then you can
remove and relocate valve to workspace.
8. Clamp valve in vise without crushing or imprinting
the gasket sealing surfaces or air chamber asm.
9. Test with shop air or other source (A) is the open
side closest to the valve (B) is closed @ sight glass.
10. If Tank Flange gasket is the only repair needed,
replace gasket (Green portion toward tank) and
proceed to #(19).
11. If Air chamber or spring require service proceed with
the following.
12. Remove cap with sight glass attached. Lay parts out
in the order they are removed.
13. Loosen lock nut inside (slowly) spring tension will
be relieved as it is removed.
14. Remove shaft and spring / pay attention to washer
in behind spring and note where it belongs.
15. Dis-assemble air chamber piece by piece and replace
O-rings, Packing & Seals and re-assemble.
16. Re-insert shaft with spring & washer, place valve
nose down/ gasket @ and on the floor.
17. Press downward on valve and compress slightly to
get lock nut started inside air chamber asm.
18. Tighten down lock nut compressing the spring and
/ Inspect & clean sight glass on end cap, apply thread
sealant if removed. (This will allow a visual
indication of Tank Suction Valve position &
operation) Install Cap.
19. Re-install valve into vise and bench test the Tank
valve one more time before installing on Distributor.
20. Place Valve asm into Strainer Box / Install air lines
and activate and open Tank Valve asm.
21. Install 510 Loctite gasket eliminator on flange and
install valve with mounting bolts.
22. Operate valve to open and closed several times to
imprint the new gasket on tank flange.
23. Check and clean Strainer.
24. Check Packing seal on Strainer Lid (replace if
needed) Install and secure Strainer Lid.
25. Fill distributor and safely test for leaks
(*Note See an illustrated breakdown of the Tank Suction
Valves in component Illustrated breakdown section)
Servicing Spraybar Swivel Joints
*Note: Swivel joint assemblies tend to leak past the
O-ring between the 2 main component parts, changing
the mounting gaskets or tightening the nuts that secure
it to the plumbing will not fix the leak.
1. Determine if the joint is able to be disassembled and
serviced or should be replaced (If the joint
moves too much side to side or has broken studs /
replace swivel joint).
2. Make sure that Spraybar is sucked back and little or
no material is left in the Circulating System.
3. Support the portion of Spraybar or Circulation
Plumbing needing to be disassembled.
4. Remove nuts & lock washers that attach the
assemble to the bar or circulating pipes (note the
Grease zerk position, and which side of joint pivots
to make sure you install it the same way)
5. Separate and remove Swivel Joint (Make sure
internal plumbing is intact and rigid. 3x3 Standard
Bar uses a pipe slip joint method / Big Bar &
Variable Width bars, use a coupling w/ O-rings to
get a positive seal at all connections. On Variable
Width bars the circulating pipe may have to be
removed @ (2) joints to get it removed from unit).
6. If replacement is you repair method, make sure to
clean all gasket surfaces, check internal plumbing
and replace O-rings if needed / if servicing joint (Go
to step # 8).
7. Install Joint with new gaskets, position grease zert
as noted earlier, Do not overtighten nuts they are
attached to a weld on stud.
8. To disassemble Swivel Joint you will need to 1st
clean the part. (Hard material will be much harder
to disassemble).
