The Honda 15111-ZA0-000 Oil Pump Body is a genuine OEM component designed for GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, and H4514, HT3813, and HT4213 lawn tractors. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit without modification. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and this body must match your exact production run.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this Oil Pump Body meets the same dimensional and material standards as the part it replaces, preserving correct oil flow geometry throughout the lubrication circuit.
- Broad Compatible Fitment — fits GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, and H4514, HT3813, and HT4213 lawn tractors, including models across multiple serial ranges.
- Serial Number Verification Recommended — Honda issues replacement parts by serial range; check your machine's serial number against the fitment table to confirm this is the correct body for your unit.
- Lubrication System Integrity — a cracked, worn, or damaged oil pump body allows pressure to drop, starving bearings and internal components of adequate lubrication and accelerating engine wear.
The oil pump body is the structural housing that encloses the oil pump's internal components — the rotor, gears, or plunger depending on the pump design — and forms the passages through which oil is drawn from the sump and pressurized before delivery to the engine's bearings and moving parts. It must maintain a precise internal geometry to sustain correct oil pressure across all operating temperatures. When the body cracks, wears internally, or develops porosity, oil pressure falls below the minimum needed to protect critical components, leading to accelerated wear, overheating, and potential engine seizure if left unaddressed.
