Servicing the Fluid Section

use of non-Wagner service parts may void
warranty. Ask for original parts made by Wagner
for best services. This pump should receive a
routine servicing after approximately 1,000 hours
Attention
of use. Earlier servicing is required if there is
excessive leakage from the top packing or if pump
strokes become faster on one stroke or the other.
The use of Wagner EasyGlide (P/N 0508619) is
recommended as an upper packing lubricant. Do
not substitute oil, water, or solvent for an upper
packing lubricant.
Numbers in parentheses refer to the item numbers

in the fluid section illustrations. If there are two
numbers, the first number represents the item
number for the LC 820 and the second number
represents the item number for the LC 840/LC 860.
Disassembling the Fluid Section
1. Remove the siphon hose assembly. Unthread the foot
valve housing (20,21) and the pump cylinder (14) with a
strap wrench.
2. Slide the retainer ring (1) up with a small screwdriver, then
push the connecting pin (2) out.
3. Pull the displacement rod (6) through the lower cavity of
the motor/pump block.
4. Remove the Teflon o-ring (3), upper packing spring (5),
and upper packing set (4) from the motor/pump block.
5. Hold the displacement rod (6) in a vise by the flats at the
top of the displacement rod and remove the outlet valve
housing (13) with a wrench while holding the displacement
rod horizontal with wooden support, if necessary. Remove
the seal washer (12), outlet valve seat (11), outlet valve
ball (10), lower packing set (4), lower packing spring (9),
sleeve (8, LC 820 only), and spring retainer (7).
6. Using a 1/2" extension bar attached to a 1/2" drive ratchet,
insert the end of the extension bar into the square opening
of the foot valve cage (16,17) inside the foot valve housing
(20,21). Unscrew and remove the foot valve cage along
with the wave washer (16, LC 840/LC 860 only) from the
foot valve housing.
7. Remove the Teflon o-ring (3), foot valve ball (17,18), foot
valve seat (18,19), and seat o-ring (19,20) from the foot
valve housing (20,21).
8. Remove the o-ring (15) from the pump cylinder (14)
Reassembling the Fluid Section
i
use Teflon tape on all threaded pipe connections.
1. Place a new seat o-ring (19,20) into the groove in the
bottom of the foot valve housing (20,21).
2. Inspect the foot valve seat (18,19) for wear. If one side
is worn, flip the seat to the unused side. If both sides are
worn, install a new seat. Place the new or flipped seat
(worn side down) into the bore at the bottom of the foot
valve housing (20,21).
3. Place a new foot valve ball (17,18) onto the foot valve
seat (18,19). Using a 1/2" extension bar attached to a 1/2"
drive ratchet, insert the end of the extension bar into the
square opening of the foot valve cage (16,17) and screw
the foot valve cage into the foot valve housing (20,21).
Torque the cage to 240 in./lbs. (20 ft./lbs.).
4. Place the wave washer (16, LC 840/LC 860 only ) on top
of the foot valve cage (16,17).
5. Insert a new Teflon o-ring (3) into the groove of the foot
valve housing (20,21). Lubricate the o-ring using oil or
grease.
6. After soaking the leather packings in oil (preferably linseed
oil), reassemble the lower packing set (4). Place the set
