New, Reman, & Used

RF Engine offers an expansive offering of new aftermarket, remanufactured, and used engines and engine parts all under one roof.

Details

Remanufactured replacement long block.

Includes rotation assembly (block, crank, rods, & pistons), cylinder head with rocker arm assemblies & valve covers, camshaft with lifters & pushrods, oil pump, oil pick-up tube, oil pan, water pump, front gear housing, and tin.

Installer re-uses injection pump gear and fuel system, starter, alternator, flywheel, intake and exhaust manifolds, turbocharger (where applicable), hydraulic or accessory drive pump, and all other external components.

This has what is called a "STORM" or "STRESS" style cylinder block which is an updated casting with thicker webbings as well as a cast embossment with a threaded port next to the oil filter head that replaces the large freeze/expansion plug present on earlier models.

While every effort has been made to ensure the accuracy of the fitment information listed above, it is ultimately the responsibility of the installing mechanic to perform a side-by-side comparison of the replacement part with the original to verify proper fit before installation. RF Engine is not liable for labor or consequential damages resulting from incorrect application.

Warranty Information

Cummins B Series Long Block Warranty

Your new Cummins B Series long block comes with a 6-month warranty covering defects in materials and workmanship. We're committed to ensuring you receive a quality product that performs as expected.


What's Covered

  • Coverage Period: 6 months from date of purchase
  • Parts Protection: Replacement parts for any component of the long block itself found to be defective in materials or workmanship
  • Our Promise: If a covered defect occurs, we'll provide replacement parts at no charge to get you back up and running

What's Not Covered

This warranty covers replacement parts only. The following costs are the customer's responsibility:

  • Labor: Installation, removal, diagnosis, or any other labor costs
  • Fluids & Consumables: Engine oil, coolant, filters, gaskets, or any other consumables
  • Shipping: Both inbound shipping of defective parts and outbound shipping of replacement parts
  • Incidental Expenses: Towing, equipment rental, downtime, or any other indirect costs

How It Works

If you experience an issue covered under warranty:

  • Contact us immediately with your order number and description of the problem
  • We'll work with you to diagnose the issue and determine if it's warranty-related
  • For valid claims, we'll ship replacement parts as quickly as possible
  • Defective parts must be returned for inspection (return shipping at customer's expense)

Important Notes

  • Professional Installation Required: We strongly recommend installation by a qualified diesel technician to ensure proper break-in and operation
  • Keep Your Records: Retain your invoice and any service records — you'll need them for warranty claims
  • Questions?: We're here to help. If you're unsure about coverage or need assistance, please contact us

This warranty gives you specific legal rights, and you may have other rights which vary from state to state.
