Morbark Eeger Beever 2131 Gas Catalytic Converter Rebuild
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.
Engine & Emissions System
| Engine | Ford 6.2L V8 Gas, 165 HP |
|---|---|
| Emissions Tier | EPA Tier 4 (gas) |
| 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
- Call or submit the fitment check form — we confirm your machine’s engine and emissions configuration before you ship anything.
- Remove your catalytic converter and ship the core to us with tracking and insurance. Ship to: New England Supply House, 14 Pinto Way, Mansfield, MA 02048
- We rebuild and return your core within 3–5 business days.
