M-Series Maintenance - Sealant Material Pump
SEALANT MATERIAL PUMP:
Examine the packing around the drive shaft for leakage. (A) Slight leakage (about 1 drip per minute)
is necessary and is a normal condition for packing and allows for expansion and proper seating of the
pump shaft. If leakage is excessive follow tightening instructions below.
TIGHTENING SEALANT MATERIAL PUMP PACKING:
With machine warmed up and material pump running, tighten the 2 lock nuts (B) evenly by only a half
turn each. Allow pump to flow for a minute and examine for leakage. If leaking continues repeat in
half turn increments until excessive leaking stops. The pump will leak about 1 drip per minute when
adjusted properly - this is normal.
The material pump is sealed by a series of compressible fibrous braded
graphite packing rings, If tightening does not reduce the leaking, replace these
packing rings. Contact your CIMLINE dealer for packing ring kit and follow the
instructions below to replace.
MATERIAL PUMP PACKING REPLACEMENT:
1) Remove the locknuts, packing gland clips, spring clip and square head bolts.
2) Slide the packing gland back as far as possible on the shaft.
3) Using a packing extractor tool (C) remove as much of the old
packing as possible.
4) Clean the shaft and adjacent parts.
5) Examine the shaft, if excessively worn or scored the pump
may need to be replaced.
6) Install new the 8 new packing rings, offsetting the open ends by 135° each.
7) Reassemble the components
8) Draw up evenly on the packing gland to
assure proper seating of the packing and
then loosen locknuts about 1/2 turn
9) NOTE: DO NOT COCK THE PACKING
GLAND. THIS MAY CAUSE BINDING OR
EXCESSIVE HEATING OF THE SHAFT
10) Run in the pump for several minutes and
observe the leakage as explained above.
(A) Slight drip in this
area is normal
