Question 1

What does '.25mm oversized' mean?

Accepted Answer

When an engine's crankshaft is damaged, it can be machined to a smaller diameter to restore a smooth surface. Oversized bearings compensate for this material removal, maintaining proper oil clearances. These bearings add 0.25mm to the standard bearing thickness.

Question 2

Do I need anything else to install these bearings?

Accepted Answer

You'll need to plastigauge to check bearing clearances during installation. Always refer to the manufacturer's specifications for proper oil clearances and torque values. A machine shop will be needed to grind the crankshaft to the correct size.

Question 3

What are the benefits of using performance bearings?

Accepted Answer

Performance bearings are made with stronger materials and tighter tolerances than stock bearings. This allows them to withstand higher loads and RPMs, which is important for modified engines. They also help to maintain consistent oil pressure, which is crucial for engine longevity.
