Morbark Eeger Beever 1922 Gas Catalytic Converter Rebuild
The Morbark Eeger Beever 1922 handles material up to 19 inches and is a high-production choice for large tree care and land clearing operations. Gas-engine 1922 models run a Ford 6.2L or PSI 6.0L V8 with a three-way catalytic converter. Sustained high-load operation breaks these down over time. New England Supply House rebuilds them fast through our core-exchange program.
Engine & Emissions System
| Engine | Ford 6.2L V8 Gas (165 HP) or PSI 6.0L 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.
