WHAT WE DO TO EVERY C15

Corrective Modifications & Upgrades

DPG Remanufacturing identifies chronic factory engineering weaknesses and implements proactive remedies during assembly to ensure your CAT C15 runs cooler and longer.

Updated Piston Cooling Jets

Replaced with high-temp hardened stainless steel configurations to prevent early cylinder liner fatigue and ensure uniform heat distribution.

Revised Cylinder Head Gasket Spec

Implemented premium graphite-steel laminate head gaskets with upgraded fire rings to handle intense combustion pressures under severe duty cycles.

Strengthened Connecting Rod Bolts

Upgraded fastener hardware torqued to enhanced OEM stretch specs, removing tensile fatigue failure points common in original runs.

Oil System Flow Improvements

Internal channels machined to clinical tolerances to increase oil volume delivery by 14% directly to high-friction camshaft lobes.

"Our fleet went through three pre-emission CAT C15s from other suppliers that failed dyno tests immediately. DPG's engine ran flawlessly on their dyno, and now has 180,000 heavy-haul miles with zero issues. Unmatched transparency."
