Morbark Eeger Beever 2131 Gas Catalytic Converter Rebuild

New England Supply House is the only company in the U.S. rebuilding wood chipper catalytic converters.
The Morbark Eeger Beever 2131 is one of the largest and most productive brush chippers in the Morbark lineup, capable of processing material up to 21 inches. The gas-engine version runs a Ford 6.2L V8 with a three-way catalytic converter. These machines work hard, and the catalyst pays the price over time. New England Supply House rebuilds them 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.
Order your rebuild
