Morbark Wood Chipper Catalytic Converter: Rebuild vs. Replace
New England Supply House is the only company in the U.S. rebuilding wood chipper catalytic converters.
Morbark makes some of the most powerful wood chippers and tub grinders in the industry. Their catalytic converter systems are built to last - but they do not last forever. When yours starts showing signs of wear, the decision you face is whether to rebuild or replace. For most Morbark operators, the math is not close.
Warning Signs in Morbark Catalytic Converters
- Exhaust smell or discoloration. If you are getting unusual exhaust odors - especially sulfur - the catalyst material inside is breaking down.
- Power loss under load. A partially clogged converter restricts exhaust flow. On a high-torque machine like a Morbark tub grinder, you will feel the difference.
- Rattling at startup or shutdown. The ceramic substrate inside the converter can fracture. Once it is loose, you are on borrowed time.
- Emissions non-compliance. Morbark equipment is common in municipal and commercial applications where emissions testing is required. A degraded converter will cause a failure.
The Cost Reality for Morbark Operators
A new OEM Morbark catalytic converter can cost $9,000 or more. A D&S Morbark rebuild from New England Supply House costs $1,150 - a fraction of that - and delivers the same result: a fully restored catalytic converter that meets OEM performance specs.
