Peterbilt engine repair and replacement

Turbo, injectors, head gasket or a complete engine. Here is a Caterpillar C15 replacement on a Peterbilt, photographed in our shop from teardown until the hood went back on.

We repair and replace Caterpillar, Cummins, Detroit and PACCAR engines in Peterbilt trucks: turbochargers, injectors, head gaskets, oil coolers, EGR coolers, in frame overhauls and complete engine swaps.

When a swap makes more sense than a rebuild

This Peterbilt came in with a Caterpillar C15 that had broken its crankshaft and a connecting rod. With damage that deep the block and head are in question, and an in frame rebuild would have kept the truck down for weeks. The owner chose a replacement C15, and we did the swap.

• Diagnosis and teardown confirmed the crankshaft and rod failure.
• The radiator and cooling package came out as one assembly.
• Engine accessories, wiring and lines were disconnected and tagged.
• The transmission was separated and pulled.
• Engine mounts were unbolted and the old C15 was lifted out of the frame.
• The replacement engine arrived on a flatbed and was unpacked.
• Accessories were transferred, the new engine set in, the transmission and cooling package reinstalled.
• Fluids, a first start, leak checks, and the hood went back on.
