The Multiquip 25640 is a genuine OEM Concrete Saw Engine Front Trunnion Complete designed for the SP6057 series MQ Pavement Saws, including the SP605716, SP605720, SP605726, SP605730, and SP605736. As an authorized Multiquip source, DHS Equipment supplies this part direct — so you get the correct fitment the first time, with no guesswork. The 25640 replaces the front trunnion assembly as a complete unit, making it a straightforward swap when the original component shows wear or damage. Keep your pavement saw cutting true by replacing a failed trunnion with the same OEM-spec part it left the factory with.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's exact specifications, ensuring the trunnion mounting geometry matches the original engine cradle design on SP6057 series saws.
- Complete Assembly — Supplied as a full trunnion welded assembly (W/A), so all mounting hardware and structural elements arrive together for a clean, efficient installation.
- Confirmed SP6057 Series Fitment — Verified for the SP605716, SP605720, SP605726, SP605730, and SP605736 MQ Pavement Saws — check your model plate before ordering.
- Maintains Blade Tracking and Cutting Accuracy — A correctly seated front engine trunnion holds the engine in proper alignment with the drive train; a worn or cracked trunnion causes vibration, misalignment, and uneven blade wear.
- Structural Integrity Under Heavy Load — Pavement saws endure constant vibration and torque loads during cutting; the OEM trunnion assembly is engineered to handle the stress cycles specific to this machine family.
The engine front trunnion is the structural mounting point that secures the front of the engine to the saw's main frame. It absorbs engine vibration and torque forces while keeping the powerplant in precise alignment with the drive system and cutting blade. When this component cracks, deforms, or wears at its pivot points, the engine shifts out of position — leading to blade wobble, accelerated belt wear, and potentially unsafe operating conditions. Replacing a damaged trunnion with the correct Multiquip 25640 assembly restores proper engine seating and keeps the saw performing to spec.
