Frequently asked questions

What is a main bearing cap bolt used for?
A main bearing cap bolt clamps the main bearing caps to the engine block, holding the crankshaft's main bearings in place under load. It's a structural fastener critical to keeping the crankshaft properly located and supported.
Which engines does this main bearing cap bolt fit?
This bolt is listed for the 2.7, 3.0, 3.6, and 4.4 litre diesel engines used across the Land Rover and Range Rover range. Confirm your specific engine capacity against your vehicle's spec plate before ordering, since bolt length and thread can differ between these variants.
Can a main bearing cap bolt be reused, or does it need replacing every time?
Main bearing cap bolts are typically torque-to-yield fasteners, designed to stretch slightly as they're torqued down. These are usually single-use: once removed, the bolt has already yielded and shouldn't be reused, so replace it as standard whenever the main bearing caps are disturbed.
What happens if a main bearing cap bolt isn't tightened correctly?
An under-torqued or reused bolt can allow the bearing cap to shift slightly under load, leading to bearing wear, knocking noises, or in severe cases crankshaft damage. Always torque to the workshop manual specification using a new bolt each time.
