New JCB 444 and 448 engines available in mechanical and electronic configurations, covering Tier 2, Tier 3, and Tier 4 emissions standards. We also stock Perkins 400 Series engines (403 and 404 models) commonly fitted to smaller JCB equipment.
Power outputs range from 55kW to 120kW, with both turbocharged and naturally aspirated options available. Every engine is supplied new and ready to fit, so there’s no waiting for a rebuild.
