Universal Parts 2-Stroke Oil Pump | Minarelli 1PE40QMB

Restore proper oil injection on your Minarelli-style 2-stroke scooter with this Universal Parts replacement oil pump assembly. Designed for the 1PE40QMB Jog-style air-cooled 50cc 2-stroke engine, this is a non-cable-operated pump — meaning oil delivery rate is controlled directly by the engine’s throttle linkage via the gear drive, without a separate manual adjustment cable. A failed or leaking oil pump on a 2-stroke engine leads to rapid engine damage; this direct-fit replacement restores the factory oil injection system.

• Non-Cable Operated: Oil delivery rate is controlled by the engine throttle linkage through the gear drive — no separate adjustment cable required. Verify your application uses this style before ordering.
• Gear-Driven: Toothed drive gear engages directly with the engine’s crankshaft or primary drive to meter oil proportionally to throttle position
• 34mm Bolt Hole Spacing: Center-to-center distance between the two mounting bolts — matches OEM mounting on compatible Minarelli-style engine cases
• Minarelli / Jog Platform: Designed for air-cooled Minarelli 1PE40QMB engines used across a wide range of 50cc scooters
• Die-Cast Aluminum Body: Lightweight, corrosion-resistant housing with brass oil outlet barbs and brass mounting hardware
