4.6 Automatic Greasing (Optional)
Introduction
The Interlube AC lubrication system has been specifically designed to
provide reliable and virtually maintenance free service. The AC
lubricator and its accessories are ruggedly constructed for faultless
operation in the most demanding applications.
In common with other electro mechanical devices however, proper
operation procedures must be carefully observed.
Operation
The AC lubricating system comprises an electrically operated lubricator and a loom of tubing connecting each
chassis bearing to its own respective pumping unit. The lubricator consists of a 1.25 litre reservoir, housing
the electronic control, electric motor and drive. The top cover incorporates a filler cap for semi-fluid grease.
Housed in the reservoir is a twin-bladed impeller designed to draw grease evenly into the pumping chamber
and give a visual indication of cam rotation. Attached to the reservoir is a carcass ring, which houses the
cams and pumping units (red 0.010cc/shot, green 0.015cc/shot, yellow 0.025cc/shot, blue 0.040cc/shot, silver
0.060cc/shot and black 0.100cc/shot). This machine is fitted with 34, blue (0.040cc/shot) pumping units.
The AC system is wired via a relay to the vehicle “SWEEP” mode system. The lubrication system only
operates when the machine is in SWEEP mode and with the Forward/Neutral/Reverse switch in Forward. In
operation the cam rotates operating each pumping unit in turn injecting a measured amount of lubricant into
each supply line. During operation a green indicator light shows on the reservoir top cover. To check for
satisfactory operation, press the TEST button on top of the unit. This will start the motor and the paddle can
be seen to rotate in the reservoir. It will rotate once in about 3 minutes before re-setting to its normal 1
rotation every 12 minute period
A 2A inline fuse is used.
The pump cycle time is 12 minutes and is not adjustable.
Maintenance
As an owner of an Interlube AC system the only maintenance you should find necessary is to periodically
check the reservoir lubricant level, topping up with the recommended lubricant as necessary, and
occasionally checking the condition of loom connections.
At all times observe the following for fault free operation.
•
Use semi-fluid grease specification NGLI 000EP.
•
Ensure stored lubricant is kept clean at all times.
•
After filling the reservoir make sure the filler cap is secured.
If the system should fail to operate satisfactorily the following diagnostic and remedial advice will help to
identify and correct any fault.
Fault Finding
A. All lubrication points are dry.
1. Cause: The lubricant reservoir is empty.
Action: Refill the reservoir and ensure that all supply pipes are free from air.
2. Cause: The reservoir has been filled with an unsuitable lubricant.
Action: Drain the reservoir and thoroughly flush the system using a light mineral oil. DO NOT USE
SOLVENT CLEANERS. Refill with the correct grade lubricant.
3. Cause: The power supply has failed and the indicator light will not illuminate.
