Vermeer BC2100XL Diesel Catalytic Converter Rebuild
New England Supply House is the only company in the U.S. rebuilding wood chipper catalytic converters.
The Vermeer BC2100XL is Vermeer's largest brush chipper, with a 21-inch capacity and the biggest infeed table in its class. It runs a Cummins QSB6.7 Tier 4 Final diesel at 275 HP with a full DOC + DPF + SCR aftertreatment system. High-production land clearing is one of the toughest duty cycles for a Tier 4 aftertreatment system. New England Supply House rebuilds degraded and plugged units through our core-exchange program.
Engine & Exhaust System
| Engine | Cummins QSB6.7 Tier 4 Final Diesel, 275 HP |
|---|---|
| Catalyst Type | Diesel oxidation catalyst (DOC) + diesel particulate filter (DPF) + SCR |
Why Catalytic Converters Fail on This Machine
Cummins Tier 4 aftertreatment combines a diesel oxidation catalyst, diesel particulate filter, and selective catalytic reduction (SCR) system. The stop-start, high-load cycle of a wood chipper is one of the most demanding duty profiles for this system. Soot accumulates in the DPF faster than passive regen can clear it. Missed or interrupted active regen cycles lead to progressive plugging. The SCR urea injector is also vulnerable to crystallization during extended storage between jobs. Substrate cracking from thermal shock during forced regen is common on high-hour machines.
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
