Rebuilds for Morbark Eeger Beever and Beever chippers

Morbark chippers on GM, Power Solutions International, and CAT power all rely on a healthy catalytic converter. When it plugs, you feel it — bogging under load, an emissions code, or a derate. D&S rebuilds your existing converter with a fresh substrate in the original housing, built to meet EPA emissions standards and backed by a warranty against manufacturing defects — for a fraction of the cost of a new OEM unit.

We rebuild every Morbark model

Eeger Beever, Beever M-series, and the newer BVR line, gas or diesel, any year — if it's a Morbark with a catalytic converter, we rebuild it. Models we handle include:

Don't see yours? We still rebuild it — every Morbark converter, any model, same flat price. Order your rebuild → Not sure it's a fit? Send a photo.

Not sure it's the cat? Bogging under load, an emissions code, or a Tier 4 derate are the usual tells. Full symptom guide → Not sure your unit qualifies? Send a photo and we'll confirm the fit.
Thinking of deleting it instead? On Tier 4 machines that usually just triggers a derate — and running without the cat can stress the engine. A rebuild is the reliable fix. Why delete doesn't work →
