CRANKSHAFT

KMP Brand Forged Shafts – Better than Regrinding

Regrinding an old shaft can be risky (micro-cracks, material fatigue). We offer brand new, forged crankshafts in standard size (STD). They are ready to install, balanced, and have hardened journals, ensuring factory durability in Turbo engines.

Crankshaft Oil Seals

Oil leaking from the gearbox or pulley is a common fault. We stock:

  • Rear seals (flywheel side): Often integrated with an aluminum housing (in newer Perkins engines).
  • Front seals (timing side): Made of Viton, resistant to high temperatures.
  • Wear Sleeves (Speedi-Sleeve): Allow you to save a shaft with a worn groove under the seal.

💡 Buying a new crankshaft?

You must replace the bearings with new STD ones. Check:

Frequently Asked Questions (FAQ)

Are KMP Brand shafts forged or cast?

Most KMP shafts for Perkins and CAT engines are Forged Steel, which ensures significantly higher fatigue strength than cheaper Cast Iron replacements.

Is the shaft sold with bearings?

Some kits (e.g., KMP Brand) may include bearings, but typically the shaft is sold "bare". Bearings must be selected separately in the correct size (usually STD for a new shaft).

Need a crankshaft gear?

Timing and oil pump gears are shrink-fitted. If yours was damaged during removal, we will select a new gear matching the tooth count.
