BEARINGS

Types of Bearings Available

A complete bottom-end rebuild requires replacing all sliding components:

  • Main Bearings: Set for main journals (holding the crank in the block).
  • Connecting Rod Bearings (Big End): Set for crankpins (connecting crank to rods).
  • Thrust Washers: Responsible for eliminating crankshaft end play.
  • Small End Bushings: Pressed into the connecting rod eye (for the gudgeon pin).

How to select size (Grinding)?

Bearings come in several thicknesses, depending on the crankshaft condition:

  • STD (Standard): For a new crankshaft or one in perfect condition (not ground).
  • 0.25mm / 0.50mm / 0.75mm: Oversize (thicker) bearings used after crankshaft grinding. The value indicates how many millimeters the journal diameter was reduced.

💡 Got the bearings?

Check the oil pump condition – it lubricates the bearings. If worn, new bearings will seize instantly.

Frequently Asked Questions (FAQ)

Are KMP Brand bearings good quality?

Yes. KMP bearings are made using multi-layer technology (copper-lead-tin), ensuring excellent seizure resistance and embeddability, identical to OEM parts.

Is the bearing set for the whole engine?

Yes, we sell complete sets ("per engine"). Buying main bearings gets you a set for all main journals. The same applies to conrod bearings.

Seized bearings?

Make sure to check the connecting rods – they often overheat and deform (turning purple). We offer new connecting rods if the old ones are unusable.
