The Royal Enfield Genuine Oil Pump Chain (Part No. RLN00028/B) is a critical internal engine component engineered explicitly for Royal Enfield’s next-generation J-Series 350cc SOHC engine platform. Operating quietly inside the crankcase assembly, this high-precision link chain drives the primary lubrication circuit by transferring mechanical rotation from the engine crankshaft directly to the internal oil pump drive sprocket.
As verified by the official packaging barcode label in image_18fb87.png and shown in the product layout in image_18fbbf.png, this chain is built with compact, heavy-duty link rollers designed to minimize mechanical drag.Utilizing the authentic RLN00028/B oil pump chain ensures a perfectly tensioned, slip-free link interface. This completely avoids chain slack, whipping, or snapping that can cause a sudden, catastrophic loss of oil circulation common with unbranded generic replacement chains.
