avoided, may result in minor or moderate injury.
Safety Instructions
This equipment generates very high grease pressure.
Extreme caution should be used when operating this
equipment as material leaks from loose or ruptured
components can inject fluid through the skin and into the
body causing serious bodily injury. Adequate protection
is recommended to prevent splashing of material onto the
skin or into the eyes.
Description
General Description
This unit is a hydraulically operated, single acting, spring
return, positive displacement pump designed to deliver
grease under pressure. The pump is primarily designed to
lubricate bushings of the tool bit in Hydraulic Hammers.
The pump can be used to lubricate bushings and bearings
on grippers and crushers. The pump is designed to be
directly installed on the hammer, gripper or crusher and
connected to the hydraulic power supply of the carrier.
Grease outlet of the pump should be connected by hose to
the point of lubrication.
The pump could be attached to an SSV divider block for
multiple point lubrication.
The pump uses grease from standard 14.5 oz. grease
cartridges, eliminating the need for bulk filling equipment.
The pump may be filled from a bulk lubricant container if
desired.
Appropriate Use
This pump is exclusively designed to dispense grease in
Hydraulic Hammer and gripper/crusher applications.
It should be operated only with hydraulic power.
The maximum ratings given should not be exceeded.
Any other use not in accordance with the instructions will
result in loss of claims for warranty and liability.

HYDRAULIC HAMMER PUMP
MODEL 85429
Series B
Pump Operation
The pump operates simultaneously with the hammer. Each
time the hammer is activated, the pump will deliver one shot
of the lubricant to the bushing of the hammer. The pump is
a single action pump and delivers the lubricant only on the
forward stroke of the piston 6, Illus. #2. The springs 8, 9,
and 10 will return the piston 6 to initial position, recharging
the pump. The springs of the pump can develop the force to
overcome 725 PSIG (49 bar) back pressure. This limiting
factor of the pump should be taken into consideration during
pump installation on the different types of the hammer
carriers.
The installation of the pump requires connection of the
pressure hydraulic line from the carrier to the pump inlet
and grease supply line from the pump outlet to the hammer
lubrication point.
The carriers have different hydraulic systems to operate the
machines and attachments. Depending on the type of the
carrier, hydraulic lines can vent the pressure very quickly or
have residual back pressure above 725 PSIG (49 bar)
retained in the lines for a long time.
Excavators and Backhoes
Main pressure of the hydraulic power supply of the excava-
tors and the backhoes drops below 725 PSIG (49 bar) very
rapidly when hammer is stopped. This will allow the spring
to return the piston to recharge the pump.
Connect the Pump to the Pressure Line. The pump will cycle
and deliver the lubricant as soon as the hammer starts to
operate. During the repositioning of the hammer to a new
location, the springs will return the piston to recharge the
pump for a new cycle. The lubrication of the hammer is done
during the hammer operation.
Carrier Type Connection Line
s
Excavator, Backhoe Pressure line
Skid Steers Return Line
Regardless of the pump connection to the pressure or
return line, if pressure fluctuation during the hammer
operation falls below 725 PSIG (49 bar) the pump can
deliver a small amount of lubricant due to the piston partial
movement. This additional lubricant output has to be taken
into consideration during selection of the Output Plug (23),
Illus. #4. to adjust the lubricant output.
Skid Steers
Skid steers with hydrostatic transmissions have a
back pressure in the return line, since hydraulic fluid
returned to the tank through the transmission itself. The
hydrostatic transmission is used to drive the skid steer
using hydraulic power generated by diesel motor. The back
pressure in the return line can vary from 350 to 1,200 PSIG
(24 to 82 bar) depending on the skid steer manufacturer,
but quickly drops to 50 PSIG (3.5 bar) or below during
hammer operation.
Connect the pump to the return line. The pump will deliver
the lubricant using the back pressure when hammer stops
to operate and will recharge during the hammer operation
when the pressure drops. So, the lubrication is done
during hammer repositioning to new location and pump will
recharge during hammer operation, this is opposite of the
lubrication cycle of the excavators and backhoes.
The connection of the pump to the carrier will depend only
on the type of the carrier and will not be dependent on the
type or manufacturer of the hammer:
ubricant Recommendations
Hammer manufacturers recommend lubricating while the
hammer is standing upright, resting on the tool to ensure
that the grease will penetrate downward between the tool
and the bushing. This recommendation is important when
lubrication is made using the manual grease gun and a
large amount of lubricant pumped into the hammer. The
upright position of the hammer with tool in a resting position
will ensure that the space between the piston and the tool
not be filled with the lubricant. Automatic lubrication with the
single stroke pump injects a very small amount of lubricant
during hammer operation and there is no need for the
hammer tool to be in a resting position.
How much lubrication is enough? The pump output should
be adjusted to make the length of the tool shank that is
traveling in and out of the bushing visibly wet with lubricant.
Do not over lubricant to the point that grease is clumping
and runs down on the tool.
Pump Output Adjustment
The pump is shipped with the minimum output metering
plug 23, Illus. #4. The plug output is 0.006 in³ (0.1 cm³).
The output of the pump can be increased by replacing the
metering plug with one of the optional plugs below:

INSTA ING THE PUMP
The pump should be installed directly on the hammer or the
carrier adapter for the hammer or attachment. It is prefera-
ble to mount the pump so that the cartridge housing (28) is
in the upright position (as shown on the front page), but
horizontal positioning is acceptable. Allow sufficient space
for cartridge changing and service. (See Fig. #2 for dimen-
sions). The red low-level indicator (18) should be readily
visible. mount the pump in a position that it will be protect-
ed from damage by any debris which may be encountered
when the hammer or attachment is in operation.
IMPORTANT: The feed line to the lube point must also be
protected from damage by armoring the line or other
suitable method of protection.
1. Lincoln recommends using Grade 8 fasteners, or
equivalent, for mounting the pump to the hammer or
adapter. It is important that two flat washer are used
between the bolt head or nut and the pump body of each
fastener. 1/2 grade 8 bolts, nuts and flat washer are
recommended. Apply 120 ft.-lbs. torque to the fasteners.
Fabricate a mounting bracket if necessary.
2. Using appropriate high-pressure hose, connect the
pump hydraulic inlet to the source of hydraulic power.
This may be either the supply or return lines to the
hammer. See above.
3. Fill the pump with lubricant. (See FILLING PUMP WITH
LU RICANT AND AIR PURGING INSTRUCTIONS.)
4. Attach the lubricant feed line to the lube outlet on the
pump.
5. Prime the lubricant feed line with lubricant.
6. Connect the lubricant feed line to the lube point. This
should be a direct connection, avoiding any grease fitting
couplers of possible.
7. Protect the lubricant feed line from damage by covering
with steel channel or angle iron if necessary.
IMPORTANT: The Low Level Indicator Rod (14) will extend
from the bottom of the pump when the grease cartridge
housing is empty. See (Fig. # 3, View D) Replace empty
cartridge or fill cartridge housing promptly with fresh lubri-
cant.
Adjusting the Spring Clip
For the Spring Clip (32) to properly retain the grease car-
tridge housing (28), it must be properly adjusted for either
bulk or cartridge filling. If the pump is to be used with
grease cartridges, the spring clip (32) must be adjusted to
fit tightly in the groove when a grease cartridge installed is
in the grease cartridge housing (28). If the pump is to be
bulk filled or filled with a pump, the spring clip should be
adjusted to fit into the groove tightly with no grease cartridge
installed in the cartridge housing (28). See Illus. #3, View A.
Refer to appropriate section for details on adjustment.
1. 271924 - 0.031 in³ (0.5 cm³)
2. 271925 - 0.018 in³ (0.3 cm³)
3. 271926 - 0.012 in³ (0.2 cm³)
4. 271927 - 0.006 in³ (0.1 cm³)
Always use Lincoln Industrial parts for service and repair.
