Disassembly (Fig. 15)
IMPORTANT: Make sure to remove and neutralize
chemicals from spray components before disas-
sembly. Wear protective clothing, chemical resist-
ant gloves and eye protection during repair.
1. Remove flowmeter from machine (see Flowmeter in
this chapter).
2. Disassemble flowmeter.
3. Clean rotor (item 2), both hubs (items 3 and 4) and
flowmeter body to remove any debris, spray chemicals
or other materials.
Assembly (Fig. 15)
1. Assemble flowmeter. Check the following items dur-
ing flowmeter assembly.
A. If turbine stud was removed from upstream hub,
apply thread sealant to threads of stud before instal-
lation.
B. Check that rotor spins freely with very little drag. If
necessary, loosen the turbine stud 1/16 of a turn and
check rotor drag. Continue the process of loosening
stud until rotor spins freely.
C. When installing hubs (items 3 and 4) into hous-
ing, make sure to align locating notch on each hub
with boss in housing bore.
D. If sensor (item 7) was removed from flowmeter
body, thread sensor into housing so it lightly bottoms
in housing. Secure sensor in position by tightening
jam nut.
E. Make sure that retaining rings are fully seated in
grooves of flowmeter housing.
2. Install flowmeter (see Flowmeter in this chapter).
