The Multiquip MM433793 Gear Oil Pump Inner BLW-300 is a genuine OEM component designed for BLW-300 series equipment. Sourced directly from Multiquip, this part meets the exact specifications required for proper lubrication system performance in your machine. MM433793 is the correct OEM replacement for the inner gear element of the oil pump assembly, confirming a direct fit for BLW-300 applications. Keep your equipment running at full capacity with an authentic Multiquip part built to the same standards as the original.
Key Features
- Genuine OEM Gear Tolerancing — Manufactured to exact inner gear profile specifications, ensuring correct displacement volume and consistent oil flow output for the BLW-300 lubrication circuit.
- Direct-Install Replacement — Engineered to drop into the existing pump housing on BLW-300 equipment without machining or fitment adjustment.
- Confirmed BLW-300 Fitment — Verified compatible with BLW-300 series machines; always cross-reference MM433793 against your serial plate before ordering.
- Sustained Oil Pressure Integrity — A correctly functioning inner gear maintains stable oil pressure throughout the system; a worn inner gear causes pressure drop, increased clearances, and accelerated bearing wear across the machine.
- Authentic Multiquip OEM Quality — Backed by Multiquip's OEM supply chain, this part delivers the same material grade and dimensional accuracy as the component originally installed at the factory.
The inner gear is the driven element at the heart of a gear-type oil pump. As it rotates within the outer gear rotor, it creates expanding and contracting cavities that draw oil from the sump and push it under pressure through the lubrication passages of the machine. When the inner gear wears, the clearance between gear teeth increases, oil slips back past the meshing point, and the pump loses the ability to maintain adequate pressure — starving bearings and moving components of the lubrication they need. Replacing a worn inner gear with a correct-specification OEM part restores full pump output and protects the broader drivetrain from premature wear.
