Cummins® 4B 3.9L Batch of Four (4) Rebuildable Long Block Cores

Cummins® 4B 3.9L Batch of Four (4) Rebuildable Long Block Cores

Details:

• Four 4-cylinder diesel Cummins® 4B 3.9L long block cores.
• Each long block includes everything from rocker covers through oil pan.
• All major castings are guaranteed to be remachinable: Block, Crank, Head, Rods, & Cam
• All four long block cores use the Non-STORM (AKA: Non-Stress) style blocks.

These cores are conveniently organized on one skid in order to keep shipping costs down. We guarantee all the major castings, the block, crank, head, cam, & rods, to be good, remachinable castings and will replace any that are not up to spec.

Cummins® B-series engines are sleeveless, so the blocks can be bored out if the cylinder walls are in need of repair. Blocks can be bored to 0.50mm or 1.00mm oversized. Should any of the blocks on this pallet not clean up at 1.00mm, or is already at 1.00mm and can't be bored any farther, we will supply a used replacment block.

Special Deal: Once you have your cores and are ready to rebuild them, consider reaching out to us for all you engine kit and parts needs. If you purchase all four (4) overhaul kits from us on one invoice, then we will credit you the freight charges paid for the skid of cores towards your engine kits.
