Keep Compatible Chain Drives Properly Maintained

A chain drive depends on more than a coating of lubricant. Links, rollers, pins & sprockets work together under repeated movement & their condition can be affected by contamination, operating load, moisture & incorrect adjustment.

WD-40 Specialist Chain Lube 237g is a dedicated chain lubricant intended for suitable applications. Its role is to provide lubrication to compatible moving chain components as part of an established maintenance procedure.

This collection currently lists the WD-40 Specialist Chain Lube 237g Pack of 12, identified by listing reference 21132-12.

The correct lubricant must always match the chain or equipment manufacturer's specification. A dedicated chain spray is not automatically suitable for every sealed chain, industrial drive or specialised operating environment.

Start With the Chain Type

Industrial roller chains

Roller chains contain moving interfaces that require suitable lubrication to manage friction & wear. Lubrication should be matched to operating speed, load & the chain manufacturer's requirements.

For replacement or additional components, explore Roller Chains – Standard, Heavy Duty.

Exposed machinery chains

Equipment operating around dust, moisture or abrasive material may need closer inspection. Applying lubricant over accumulated contamination is not a substitute for proper cleaning.

Vehicle chains

Motorcycle & other vehicle chains may use sealed construction. Confirm lubricant compatibility with the chain manufacturer, particularly for O-ring or X-ring designs.

Agricultural & outdoor equipment

Outdoor chain drives can face variable working conditions. Lubrication frequency, cleaning methods & replacement intervals should reflect the equipment's actual duty cycle.

Chain Lubricant vs General-Purpose Spray

Choosing the wrong product can create maintenance problems even when the application seems straightforward.

A chain lubricant should be selected because it meets the application requirements, not simply because it is available at the maintenance bench.

Inspect the Entire Chain Drive

Lubrication cannot correct worn sprockets, excessive chain elongation or misalignment.

Before applying a product, inspect the drive according to the manufacturer's procedure.

► Chain wear: Check elongation against the specified replacement limits.
► Link movement: Look for stiff, damaged or corroded links.
► Sprocket condition: Examine tooth wear & engagement.
► Alignment: Check that the chain runs correctly through the drive.
► Tension: Confirm adjustment against the equipment specification.
► Contamination: Remove unsuitable deposits using an approved method.
► Lubricant compatibility: Verify the selected product meets the application requirements.

A Better Chain Lubrication Routine

Isolate the equipment

Follow the required shutdown & isolation procedures. Never place hands or applicators near moving chain drives.

Inspect before cleaning

Identify damaged components, abnormal wear or contamination that may need attention before lubrication.

Clean appropriately

Use a cleaning process compatible with the chain materials, seals & equipment requirements. Some cleaning chemicals can be unsuitable for specific chain constructions.

For separate cleaning products, browse Cleaning Chemicals & Solutions.

Apply the specified lubricant

Follow the WD-40 product label & equipment manufacturer's application instructions, including quantity, application points & any required waiting period.

Check chain tension & alignment

Lubrication does not compensate for incorrect mechanical adjustment.

Refit guards & complete inspections

Confirm the equipment is ready to return to service under the applicable workplace procedure.

When Lubrication Isn't Enough?

Repeated chain noise, abnormal vibration, stiff links or frequent tension adjustment may indicate mechanical wear or another problem.

The solution may involve inspection, adjustment or component replacement rather than applying more lubricant.

For relevant mechanical adjustment components, explore Chain Tensioners & Guides.

Chain Maintenance in Australian Working Conditions

A workshop conveyor, outdoor agricultural machine & vehicle chain can experience very different operating conditions.

Dust & abrasive material

Inspect chains for contamination before lubrication. Dirt trapped around moving components may contribute to wear.

Moisture exposure

Check exposed chains for corrosion & follow the manufacturer's maintenance recommendations after significant exposure.

Frequent operating cycles

Equipment with high utilisation may require more frequent inspection. Use the prescribed maintenance interval as the starting point.

Extended storage

Chains returning to service should be inspected for corrosion, stiffness, contamination & deterioration.

Buying Chain Lube for Scheduled Maintenance

A pack of 12 may be appropriate for businesses maintaining multiple compatible chain-driven machines, but purchasing should be based on the actual servicing requirements.

Consider:

► How many machines use the specified lubricant.
► The manufacturer's recommended lubrication intervals.
► Expected consumption across maintenance cycles.
► Whether the product is approved for the relevant chain types.
► Aerosol storage requirements.
► The current selling unit & supplier product code.

Workshops servicing chain-driven equipment may also need related components such as Bearings. Bearings have their own lubrication requirements, so do not assume chain lube is suitable for them.
