This bundle focuses on the core components and tools needed for the second phase of a heavy-duty N-14 Cummins engine overhaul. It targets experienced diesel mechanics or serious DIYers performing a complete in-frame rebuild. The selection covers critical engine parts, specialized tools, and essential shop supplies to ensure a successful and complete restoration.
Curated by Workshop Notes · Updated June 2026
Built for experienced diesel mechanics and hobbyist restorers performing a full N14 bottom-end rebuild in their own shop. Not for general automotive light-duty work—this shop focuses strictly on heavy-duty Class 8 engine overhaul needs.
Most people try to cheap out with a slide hammer, but on a crusty N14 block, you need a mechanical puller like this to get a clean, square lift without scoring the counterbore. It saves hours of frustration when dealing with seals that have been heat-cycled for half a million miles.
⚠ Worth knowing: This kit is sized for the N14 specifically; if you are working on an older Big Cam or a newer ISX, the liner puller and torque specs won't cross over. Also, don't attempt this rebuild on a standard 1,000lb engine stand, as a fully dressed N14 block will snap a light-duty head plate instantly.
