Description
Graco Automatic Lubrication System
Refer to Fig. 1. Graco’s single-line parallel automatic lubrication system offers positive displacement lubrication
measurement for multiple lubrication points. This system was designed for use on mobile mining equipment, spe-
cifically haul trucks. At the heart of this system is the Graco Fireball pump, the most durable pump in the industry.
The pump provides the lubricant pressure needed to activate the automatic lubrication system.
The entire system consists of a pump module, injectors and system controls. The pump module provides the sys-
tem inherent pressurization and venting cycles to activate the injectors. The injectors measure precise amounts of
grease to be dispensed to individual bearing points during an automatic lube cycle. The controls consist of a timer
and a solenoid operated valve which turn the pump on at the required lubrication intervals.
This System Design Guide provides general system information to aid and assist the user in designing, installing
and operation of an automatic lubrication system to meet the lubrication requirements of the designated equipment.

Automatic Lubrication Definitions
Definitions
“Pump on” time
The duration that the pump has power supplied to it. This is controlled by the timer. All injectors must fully dis-
pense within this time frame in a properly designed system.
“Pause interval” time
The duration between automatic lubrication cycles. This is also controlled by the timer. All injectors must fully vent
within this time frame in a properly designed system.
Vented
The state of the injector after pressure is relieved at the inlet. It also means the measured amount of grease is fully
transferred to the dispensing chamber of the injector.
Main supply line
The line that supplies lubricant from the pump module to the injector groups or banks.
Branch supply line
The line that branches off the main supply line to feed individual injector banks. The branch supply line prevents
system venting problems in cold weather by minimizing the amount of grease vented through the injector manifolds.
Feed line
The line that supplies lubricant from the injectors to the bearings.

10 309015
System Components
1. Controls
Timer
8852A
The timer is the “brain” of the automatic lube system. It requires a constant 24 volt power supply. Its function is to
supply and remove power from the pump module via a solenoid valve, at predetermined time intervals. The timer
must be programmed for “pump on” and “pause interval” settings.
Solenoid valve
9008A
The solenoid valve is controlled by the timer. The function of the solenoid valve is to turn the power supply on for
the pump module. The solenoid operates on a 24 volt signal received from the timer. The solenoid also has a
manual override button to activate the pump module.
Pressure switch (optional)
9146A
A pressure switch can be installed in an automatic lube system for additional system control and safety. A normally
open pressure switch when properly connected to the timer and installed so that it monitors supply line pressure will
turn the pump module off upon detection of a preset pressure, normally 2500 psi (172 bar, 17 MPa). Two advan-
tages of a pressure switch are:
It can monitor system for faults.
It can turn the power supply to the pump off when a preset pressure has been reached.

Pump
The pump provides the necessary lubricant pressure needed to operate the injectors.
Vent valve
9037A
The vent valve relieves the lubricant pressure back to the reservoir at the end of each lubrication cycle.
Pressure relief
9037A
The pressure relief valve is a safety item to prevent over-pressurization of the system. Never operate your auto-
matic lube system without a pressure relief valve. The pressure relief valve is factory set at 4000 psi and is non-
adjustable.
Reservoir
The primary function of the reservoir is to contain the lubricant intended for later dispensing into the bearings. The
reservoir has several features. The vent line is external to the reservoir to allow for trouble free follower plate op-
eration. The fill port of the reservoir is at the bottom of the reservoir and is specifically designed such that it is im-
possible to fill the reservoir and later realize the follower plate is at the bottom of the reservoir instead of at the top
where it belongs. The overflow port is located above the fill port and can be opened to determine when the reser-
voir is full during filling.
Follower plate
The function of the follower plate is to prevent grease tunneling and pump cavitation.

System Components (cont.)
3. Injectors
Injectors
The function of the injector is to measure a preset amount of lubricant for dispense into bearing points for each au-
tomatic lubrication cycle. Injector outputs can be combined for a common bearing point with a large grease require-
ment but the output for a single injector can not be split into multiple bearing points. The injectors come in various
mounting configurations as shown below. For details of injector operation, refer to page 23.
Manifold mounted
9061A
Manifold
1 to 5 injectors mounted on a common inlet manifold. Up to 5 injector outputs can be combined for dispense to a
common bearing point with a large grease requirement using a cross over kit.
Replacement
9654A
Single injector used for replacing old worn out injectors onto installed manifolds.

4. Lubricant
Graco suggests the use of the following lubricant grades for the given temperature ranges.
NLGI #1 ( 0 F to +130 F)
NLGI #0 (–40 F to +30F)
5. Distribution Lines
Main supply line
Line that supplies lubricant from the pump module to the injector groups or banks.
Branch supply line
Line that branches off the main supply line to feed individual injector banks. Prevents system venting problems in
cold weather by minimizing the amount of grease vented through the injector manifolds.
Feed line
Line that supplies lubricant from injectors to bearings.

Automatic Lubrication System Design Guide
System Design
Outlined below is a simple five step method for designing a single line parallel automatic lubrication system for a
haul truck.
Step 1: Identify points for lubrication
Step 2: Determine grease volume requirement for each bearing size
Step 3: Determine number of injectors per point, injector setting and timer setting
Step 4: Determine supply line and feed line plumbing requirements
Step 5: Determine bill of material
Step 1: Identify points for lubrication.
First, make a rough sketch of the equipment being lubricated. Number the points to be lubricated and put these
points into groups. The groups will be made up of a number of lubrication points where feed lines can be connected
from a central location.
Hint: Group points with common locations together. Most haul truck systems have three groups of injectors. One
at the rear of the truck for the shock absorber joints and box joints, and one on each side of the truck located near
the front wheels. These groups typically lubricate the steering joints and front struts of the truck.
Enter the points on the System Worksheet (page 15) with the number and brief description.
Indicate whether the bearing is a flat, journal, or roller bearing.
Step 2: Determine grease volume requirement for each bearing size
Enter the bearing dimensions on the System Worksheet. Use the appropriate Volume Chart (page 16) to determine
the bearing lubricant volume for each point based on the bearing dimension. Record the volume on the System
Worksheet.
NOTE: The Volume Charts use an assumption of a 0.002” film thickness of lubricant to calculate the bearing lubri-
cant volume.
Step 3: Determine number of injectors per point, injector setting and timer setting
Using the Injector and Timer Setting Chart on page 17, place a check mark in the corresponding bearing volume for
each lube point from the calculations in the System Worksheet. Round up to the next higher volume.
After you have recorded all of the points of lubrication on the Injector and Timer Setting Chart, you will be able to
select a time setting. From the chart, notice that as you extend the timer pause interval you may need more than
one injector for a single point of lubrication. Therefore, select a time setting where all the points can be serviced
with the minimum number of injectors.
NOTE: If you have a few points that are far to the right on the chart, you can use more than one injector to lubricate
each of those points. If you have a point that does not make the chart on the left side, you can set the injector to
the minimum setting and slightly over-lubricate that point. Or, you may decide the point is so small that you do not
include it in the system.
Once you have selected a time setting, record it on the System Worksheet. Based on the selected time setting, de-
termine the number of injectors per point of lubrication and the injector setting. Record this information on the Sys-
tem Worksheet.

Automatic Lubrication System Design Guide
Step 4: Determine supply line and feed line plumbing requirements
When connecting the supply line to several groups of injectors, use a branch supply line that comes off the main
supply line to prevent having to vent through a number of injector manifolds. Use the same size lines for the main
supply line and branch supply lines with these systems.
NOTE: Per JIC standards, copper tubing should not be used in lubricant systems.
Supply line recommendations:
Up to 40 ft in any one direction from the pump to the furthest injector bank.
3500 psi minimum working pressure.
1/2 in. ID hose or 1/2 in. steel tubing (.049 wall thickness) or 3/8 in. Schedule 40 pipe.
Up to 70 ft in any one direction from the pump to the furthest injector bank.
3500 psi minimum working pressure.
5/8 in. ID hose or 5/8 in. steel tubing (.049 wall thickness) or 1/2 in. Schedule 40 pipe.
Steel tubing must be soft annealed D.O.M. welded or seamless hydraulic fluid line tubing.
Feed line recommendations:
Up to 17 ft maximum hose length
3000 psi minimum working pressure.
1/4 in. ID hose.
Up to 26 ft maximum hose length
3000 psi minimum working pressure.
3/8 in. ID hose.
Step 5: Determine bill of material
From the original layout sketch determine how many injectors will be required in each group. Make sure to allow for
additional injectors for those lubrication points that require more than one injector. Determine the number of injector
manifold assemblies required for each bank of injectors and total. Include injector accessories such as cover caps
and outlet adapter kits.
Select the proper pump and reservoir assembly, timer, solenoid and necessary controls. The final step is to calcu-
late the supply line, feed line tubing, fittings and connectors for a complete system. As a rule, you can calculate 15
ft per point for the bulk feed line hose which is cut to length and assembled during installation.
