Morbark BVR19 Gas Catalytic Converter Rebuild

New England Supply House is the only company in the U.S. rebuilding wood chipper catalytic converters.
The Morbark BVR19 is the 19-inch capacity version of the BVR series, built for large-scale tree removal and land clearing. Gas-engine BVR19 machines run a PSI 6.0L V8 at 174 HP with a three-way catalytic converter. Hard professional use degrades these converters significantly. New England Supply House rebuilds them through our core-exchange program.

Why Catalytic Converters Fail on This Machine
Wood chippers run at wide-open throttle continuously — a duty cycle few engines sustain for hours at a stretch. That constant high-load operation drives exhaust temperatures well above the normal operating range, accelerating catalyst substrate degradation. PSI engines are GM Vortec-based with port fuel injection, and as valve seals wear over time they introduce small amounts of oil into the combustion chamber. Oil contamination is one of the fastest ways to destroy a three-way catalyst: the phosphorus and zinc additives in engine oil coat the precious-metal substrate and permanently reduce conversion efficiency. Once that happens, the only fix is a rebuild.
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
Your Morbark BVR19 uses the gas rebuild. Checkout takes a minute, then we email shipping or drop-off instructions for your core. Rebuilt and on its way back in 1–2 business days, typically.
