BLOCK

Piston & Crank Mechanism (KMP Brand & Perkins)

The solid foundation of your engine. We offer components made of materials with increased thermal resistance, ideal for high-stress Turbo units:

  • Pistons, Rings, Liners: Cylinder repair kits. Available pistons with Al-fin inserts (reinforced ring groove) and liners (unfinished or finished/honed).
  • Crankshafts: New forged crankshafts (standard size), ready for installation without grinding.
  • Bearings: Main, conrod (big end), and thrust bearings in a full range of sizes (STD, 0.25, 0.50, 0.75).

Timing, Connecting Rods, and Housings

In addition to the main rotating elements, the Engine Block category includes complete mechanical ancillaries:

  • Connecting Rods: Checked for axial alignment, small end bushes also available.
  • Timing Components: Timing gears, belt tensioners, and timing belts (for OHC engines).
  • Housings and Covers: Aluminum timing covers (often cracked in collisions) as well as flywheels and ring gears.

💡 Assembling the engine block?

After rebuilding the bottom end, sealing is essential. Don't forget to add to cart:

Frequently Asked Questions (FAQ)

Are KMP Brand crankshafts forged?

Yes, most KMP crankshafts for Perkins and CAT engines are forged, which ensures significantly higher resistance to twisting and cracking compared to cheaper cast replacements.

How to choose the right piston kit?

The engine number (e.g., AK, RG, RE) is key. Manufacturers used different combustion chambers and piston heights in the same machine model. Provide us with the number from the block – we will select the correct type.

What does a "Cylinder repair kit" contain?

A standard single-cylinder kit contains: a piston, a ring set, a gudgeon pin with clips, and a cylinder liner (unless it is a parent bore engine without liners).

Need a quote for a full rebuild?

Send us a list of required parts or just the engine number. We will prepare a comprehensive offer for KMP Brand parts (Pistons, Crankshaft, Bearings, Gaskets) at a special package price.
