Genie & JLG Diesel Boom Lift & Telehandler DOC Rebuild
New England Supply House rebuilds the diesel oxidation catalyst (DOC) on Genie and JLG diesel boom lifts and telehandlers — send us your core and we’ll rebuild it with new internals, built to meet EPA emissions standards, for a fraction of OEM cost.
How the rebuild works
Core exchange is required — we rebuild your catalytic converter, so we need your core to complete the job.
- Get a quote and place your order. Tell us your machine’s model, engine, and serial. We’ll reply with a price and set up your order.
- Get your converter to us. Choose drop-off or shipping — drop-off is by appointment at our Foxboro shop, or ship it to us from anywhere in the country with tracking and insurance. We’ll send instructions with your order. We rebuild your unit with new internals, built to meet EPA emissions standards.
- Back to work in 1–2 days (typically). Standard turnaround is 1–2 business days from receiving your core. Need it sooner? Ask about expedited service.
Which Genie & JLG lifts have a rebuildable DOC
Tier 4 Final diesel Genie and JLG boom lifts and telehandlers under about 74 hp run a Deutz 2.9L or Kubota diesel with a standalone diesel oxidation catalyst (DOC) — DOC-only, no DPF/DEF on most sub-56 kW units.
Electric scissor and mast lifts have no catalyst. Larger telehandlers above 74 hp pair the DOC with a DPF. We rebuild the DOC. Not sure which you have? Call 774-701-6374 with your engine model and serial and we’ll confirm you have a rebuildable core before you ship.
Pricing: Off-road converter rebuilds are quoted per engine and converter — call 774-701-6374 for your price.
