The Starter Ring Gear Perkins Engine – 02/100078 is a flywheel-mounted ring gear designed to engage with the starter motor pinion during engine starting. JCB parts catalogues identify 02/100078 as a “Gear starter ring,” and aftermarket parts references associate the number with Perkins-engine applications.
This JCB Starter Ring Gear 02/100078 is commonly referenced for Perkins-powered JCB equipment, including selected JCB 3CX Spare Parts and JCB 4CX Spare Parts applications. Some parts references specify a 115-tooth flywheel ring gear and list Perkins 0410236 / 410236 as an associated replacement reference; however, fitment can vary by engine and machine configuration, so always verify the existing part number, tooth count and dimensions before purchase.
A correctly fitted starter ring gear helps provide proper engagement between the starter motor and engine flywheel, supporting reliable engine cranking and reducing the risk of improper starter-pinion engagement.
