What is the difference between Holden and Ford bearings?
In short, there isn’t a universal “Holden bearing” versus “Ford bearing” that applies across all engines. Bearings are specified by the engine design, model, and year, with parts sized and tuned to each crankshaft journal and block. The practical difference you see in the market comes from the engine family and OEM part numbers, not the brand label.
What bearings are and why the brand matters
Holden and Ford engines use a range of bearings named by function (main, rod, cam, thrust, etc.). Even when the same bearing type exists, the exact dimensions and tolerances differ by engine family; using the wrong size can cause oil clearance problems, knocking, or failure. The brand matters only insofar as the engine design dictates which bearing kit is correct.
Types of bearings used in Holden and Ford engines
There are several bearing types common to both brands. The following list outlines the main categories you’ll encounter when servicing Holden- or Ford-powered engines.
- Main bearings: support the crankshaft and control end play.
- Rod (journal) bearings: sit between the connecting rods and the crankshaft journals.
- Cam bearings: support the camshafts in engines with replaceable cam bearings.
- Thrust bearings or thrust washers: control axial movement of the crankshaft.
- Oil pump and timing gear bearings: some engines use specific bushings or bearings in oil pump drives.
Bearings come in standard and undersize sizes to compensate for wear in a rebuilt engine. When you rebuild, you must choose the exact undersize that matches measured clearances.
Engine-family considerations: how Holden and Ford differ
Because engine design details vary by family and production year, Holden and Ford bearings are not interchangeable across all models. The key is to identify the exact engine code, model year, and the OEM bearing kit required by the service manual or parts catalog. Some general tendencies exist in common Australian-market engines, but always verify with the official part numbers.
Holden engine families and bearing selection
Holden engines in Australia have historically relied on GM powertrain bearings and shared some design elements with other GM brands. When selecting bearings for a Holden engine, reference the engine family code and the factory service manual to ensure the correct journal diameters and oil-clearance targets are met. Aftermarket options (ACL, Clevite, King, etc.) are available, but cross-reference carefully to avoid incorrect fitment.
Ford engine families and bearing selection
Ford engines used in Australia, including Falcon and Territory models through various generations, also require engine-specific bearings. The bearing set must match the crank journal sizes and block bore spacing for the exact engine variant. As with Holden, rely on the OEM part numbers or validated aftermarket cross-references to avoid mismatches that could compromise oiling and longevity.
In both cases, professional guidance is recommended for a rebuild to ensure you are using the correct undersize and the proper lubrication considerations.
How to choose the right bearing set
Before selecting bearings, prepare by gathering essential information about your engine and vehicle. The following steps help ensure you get the correct parts the first time.
- Identify the exact engine code, displacement, and generation (for example, the Holden/GM family or Ford engine code and year).
- Obtain the official service manual or OEM parts catalog cross-references for the correct bearing kit and undersizes.
- Measure journal diameter and oil clearance with appropriate tools, or have a professional assess wear to determine undersize needs.
- Consider reputable aftermarket brands and verify compatibility; cross-reference part numbers rather than relying on brand alone.
Using the wrong bearings can lead to improper oil clearance, insufficient lubrication, accelerated wear, or failure. Precise selection and proper installation torque are essential for engine longevity.
Practical consequences of incorrect bearings
Selecting the wrong bearing type or size can result in a variety of issues, from increased oil consumption and knocks to catastrophic bearing failure. If you’re rebuilding an engine, take time to verify all clearances and follow the manufacturer’s torque and oiling requirements.
To avoid problems, consult the official service documentation or a qualified mechanic when in doubt, especially for brand-specific engine families.
Summary
In essence, the difference between Holden and Ford bearings is not a brand label, but the engine-specific specifications. Bearings must match the engine family, journal sizes, and clearances. Always use the correct OEM or verified aftermarket bearing kit for the exact engine variant, and consult the service manual for installation guidance.
