Vermeer BC1800XL Diesel Catalytic Converter Rebuild
New England Supply House is the only company in the U.S. rebuilding wood chipper catalytic converters.
The Vermeer BC1800XL is one of Vermeer's most popular professional brush chippers, with an 18-inch capacity and class-leading infeed table. Diesel models run either a John Deere 4045 (173 HP) or Cummins F3.8 (134 HP) Tier 4 Final engine with DOC/DPF aftertreatment. Hard chipping duty degrades these aftertreatment systems significantly over time. New England Supply House rebuilds them through our core-exchange program.
Engine & Exhaust System
| Engine | John Deere 4045 Tier 4 Final (173 HP) or Cummins F3.8 Tier 4 Final (134 HP) |
|---|---|
| Catalyst Type | Diesel oxidation catalyst (DOC) + diesel particulate filter (DPF) |
Why Catalytic Converters Fail on This Machine
John Deere Tier 4 Final engines use an integrated exhaust filter (IEF) combining DOC and DPF functions. The system is designed for continuous-duty applications, not the stop-start cycle of a brush chipper. Frequent cold starts and short run times prevent the filter from reaching passive regen temperature, leading to progressive soot loading. When the filter plugs, backpressure codes appear and chipping performance drops. Ash loading from normal oil consumption also contributes to filter plugging over time.
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.
