The Multiquip 04016 Engine Washer is a genuine OEM component designed for QP-series trash pump and centrifugal pump models including QP3TK, QP2TK, QP3TH, QP2TH, QP3TB, QP2TB, QP3TZ, and QP2TZ. As a direct Multiquip OEM part, the 04016 is manufactured to the same standards as the original hardware installed at the factory, ensuring a consistent, dependable fit every time.

DHS Equipment stocks this part to keep your equipment running with correctly spec'd components.

Key Features

• Genuine OEM Hardware Integrity — Manufactured to exact Multiquip specifications, ensuring correct load distribution and seating against the engine mounting surface where tolerance matters most.
• Direct-Fit Replacement — Installs in the same position as the original without any modification to mounting hardware or adjacent components.
• Broad QP-Series Compatibility — Confirmed fitment across QP3TK, QP2TK, QP3TH, QP2TH, QP3TB, QP2TB, QP3TZ, and QP2TZ pump models.
• Protects Engine Mounting Surfaces — A correctly seated washer distributes fastener load evenly, preventing surface damage, fastener loosening, and vibration-related wear over time.
• Fuel System and Engine Safety Relevance — Proper engine fastener hardware is critical on pump units where vibration and fluid exposure are constant; using the correct OEM washer supports safe, secure engine retention.

An engine washer serves as a load-spreading interface between a fastener and the engine or engine mounting surface it secures. By distributing clamping force across a wider surface area, it prevents fasteners from pulling through or damaging softer material, and it resists loosening caused by the constant vibration that pump engines produce during operation. When a washer is missing, undersized, or worn flat, fasteners can work loose over time, leading to engine movement, misalignment, or accelerated wear on surrounding components.
