Carlton Apache 2518 Gas Catalytic Converter Rebuild
New England Supply House is the only company in the U.S. rebuilding wood chipper catalytic converters.
The Carlton Apache 2518 is an 18-inch capacity drum chipper with a 25-inch by 18-inch infeed opening, built for whole-tree chipping and high-production use. The gas-engine 2518 runs a Ford liquid-cooled V8 at 165 HP with a three-way catalytic converter. The aggressive duty cycle of a large drum chipper accelerates catalyst wear. New England Supply House rebuilds these through our core-exchange program.

Why Catalytic Converters Fail on This Machine
The Ford 6.2L is a proven industrial engine, but wood chipping duty pushes it hard. Continuous wide-open-throttle operation generates sustained exhaust heat that degrades the catalyst substrate over thousands of operating hours. Like other port-injected V8s, the 6.2L can develop valve seal wear over time, introducing oil ash into the exhaust stream. Oil-contaminated three-way catalysts lose conversion efficiency progressively — performance drops and fault codes appear — and cannot be cleaned back to spec. A rebuild is the only reliable solution.
What’s Included in the Rebuild
- Full disassembly and inspection of the catalyst housing and substrate
- New catalyst substrate installed to OEM specifications
- Reassembly using your existing housing (core exchange — your housing returns to you)
- Performance verification before return shipping
- Warranty against manufacturing defects
How Core Exchange Works
Core exchange is required — we rebuild your catalytic converter, so we need your core to complete the job.
- Place your order. Order the converter rebuild you need — gas or diesel — at newenglandsupplyhouse.com.
- Get your converter to us. Choose drop-off or shipping at checkout and we’ll send instructions — drop-off is by appointment at our Foxboro shop, or ship it to us from anywhere in the country. We rebuild your unit with new internals.
- Back to work in 1–2 days (typically). Standard turnaround is 1–2 business days. Need it sooner? Ask about our 24-hour rush rebuild.
