Morbark Eeger Beever 1821 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 1821 is an 18-inch capacity brush chipper built for heavy commercial use. Gas-powered 1821 machines come with either a Ford 6.2L V8 or PSI 6.0L V8, both running a three-way catalytic converter. The demanding duty cycle of professional chipping accelerates catalyst wear significantly. New England Supply House rebuilds these through our core-exchange program.
Engine & Exhaust System
| Engine | Ford 6.2L V8 Gas (165 HP) or PSI 6.0L V8 Gas (~165 HP) |
|---|---|
| Catalyst Type | Three-way catalytic converter (TWC) |
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
