Correct lubrication is one of the most critical aspects of maintaining 1946–1948 Ford V8, Mercury V8 and Lincoln V8 and V12 vehicles. Proper lubrication reduces friction, prevents excessive wear and ensures that all moving components operate smoothly under load. Without regular lubrication, even well-maintained components can suffer premature failure.
- Why is lubrication important? It reduces friction, prevents wear and extends component life.
- How often should lubrication be carried out? At regular service intervals, including every 1000 miles and during major servicing.
- What areas require lubrication? Engine components, chassis points and moving mechanical linkages.
Factory lubrication schedules are designed to ensure that every critical component receives the correct type and quantity of lubricant at the proper interval. This includes engine components, chassis points and various mechanical linkages that rely on consistent lubrication for reliable operation.
Lubrication must be carried out systematically to ensure that all required points are serviced and that no components are overlooked.
Engine Lubrication Points
- Check engine oil level regularly and maintain at correct level
- Replace engine oil at recommended service intervals
- Ensure correct oil grade is used for operating conditions
- Inspect for oil leaks around gaskets and seals
Chassis Lubrication Points
- Lubricate all grease fittings on suspension components
- Apply grease to steering linkage points
- Lubricate universal joints where applicable
- Ensure all chassis lubrication points receive proper coverage
Body & Mechanical Linkage Lubrication
- Lubricate door hinges to ensure smooth operation
- Lubricate striker plates and locking mechanisms
- Apply lubricant to control linkages and moving joints
- Ensure pedals and associated linkages operate freely
Cooling & Auxiliary Components
- Inspect water pump operation and lubrication condition
- Check fan hub and associated components where applicable
- Ensure auxiliary components operate without binding
Components Requiring No Lubrication
- Certain sealed components are designed to operate without additional lubrication
- Do not apply lubricant where it is not specified, as this may attract dirt and cause premature wear
Proper lubrication is not simply a matter of applying grease or oil, but ensuring that the correct lubricant is used in the correct location and at the correct interval. Over-lubrication can be just as harmful as insufficient lubrication, particularly where excess grease may contaminate surrounding components.
A consistent lubrication routine ensures smooth operation across all systems and plays a key role in preventing mechanical wear. It also allows early detection of developing issues such as loose fittings, worn joints or leaking seals.
Maintaining correct lubrication across all service points is essential for preserving the reliability and longevity of these vehicles, particularly where original components are being retained as part of restoration or continued use.
