Disassembly
To disassemble the pneumatic concrete vibrator,
♦
first remove the lock wire and four screws from
the swivel collar (A). Clamp the shell (B) carefully
in a chain vice. Hold the shell (B) close to the end
cap (C), to avoid distorting thinner portion of shell
wall.
Remove the end cap (C) from the shell (B), which
♦
has a left-handed thread.
Loosen the hose clamp (J) and remove the live air
♦
hose (K) from the eccentric shaft.
Remove the assembled shaft and eccentric weight
♦
(D) from the shell.
Remove locknuts (E and F) and remove end plates
♦
(G and H) which are a press fit. Remove eccentric
weight and rotor blades (I).
Thoroughly clean and inspect the eccentric
♦
assembly. Be sure that old rotor blades or
replacement rotor blades have a free, sliding fit
in the slot of the eccentric shaft.

When assembling the pneumatic concrete

vibrator, first key upper end plate (G) to eccentric
shaft using press fit. Make sure that the "locknut
side" of the end plate is outward and then tighten
a new locknut (E). Snug against plus
NOTICE Check part numbers carefully to be
sure that the upper end plate (G) and lower end
plate (H) are assembled correctly. The lower end
plate is slightly smaller in diameter than the upper
end plate. The machine can not be assembled if
they are reversed
♦ Assemble the rotor blades in shaft with slots down
and in shaft as shown in picture below.
♦ After placing the eccentric weight (D) on the shaft,
key the lower end plate (H) on the shaft using
press fit. Make sure that the "lock nut side" of the
end plate is outward and then tighten a new
locknut (E). Snug against plus
clearance between the eccentric weight and the
end plates, repair assemblies should have .004 in.
- . 007 in. (0.1 – 0.18 mm) clearance.
Heat the shell (B), not more than 450°F (230°C)
♦
to expand the bore and drive the eccentric
assembly into the shell until it bottoms firmly.
Check that flats in end plates is carefully aligned
with flats in interior of the shell.
Pull the live air hose (K) through the end cap (C)
♦
and clamp to end of the eccentric shaft. Hold the
shell in a chain vice, screw the end cap into the
shell as tightly as possible, left-handed thread.
When assembling the end cap use anti-seize
♦
lubricant on threads. If a new exhaust hose is
required, force the hose on the cap. Leave at least
3 ⁄ in. (19 mm) of the hose for lower hose clamp
4
(L) and assemble the upper hose clamp (M) first.
As the upper hose clamp is tightened, the hose
flows downward, leaving additional space for the
lower hose clamp.
Fasten the swivel collar (A) to the inlet using four
♦
screws and a lock wire.
