Multiquip 1490 Filter Head

The Multiquip 1490 Filter Head is a genuine OEM component designed for DAC7000SSA, DAC7000SSW, DAC7000SS, DA7000SSA2GH, DA7000SSA2, B46, BS90C, BH11C, BH90C, BS46H11, BS46H90, B46S90, and B Series walk-behind power trowel and diesel generator equipment. As a factory-sourced part, the 1490 is produced to the exact tolerances and material specifications of the original, ensuring a correct installation without modification. Sourced directly through Multiquip's OEM supply chain, this filter head is the trusted choice for operators who demand consistent performance across both generator and trowel applications.

Key Features

• OEM-Matched Construction — Manufactured to the same material grade and threading specification as the original filter head, ensuring a proper seal and consistent filtration performance across every service interval.
• Direct-Mount Replacement — Threads directly onto the existing filter housing on compatible models, aligning precisely with OEM port geometry for a leak-free connection.
• Broad Fitment Coverage — Confirmed for DAC7000SS series generators and B Series walk-behind power trowels including B46, BS90C, BH11C, BH90C, BS46H11, BS46H90, and B46S90.
• Filtration System Integrity — A correctly functioning filter head maintains proper oil or fuel flow pressure to downstream components; a cracked, warped, or cross-threaded head causes filter bypass and accelerated engine wear.
• Fuel System Safety Compliance — On diesel-powered equipment, a compromised filter head can allow unfiltered fuel into the injection system — using the correct OEM-spec replacement maintains system integrity and protects high-precision fuel components.

The filter head is the structural mounting point that secures the filter cartridge to the engine or fuel system and provides the sealed passageway through which fluid flows into and out of the filter media. It must maintain a consistent pressure-rated seal across operating temperature cycles — a warped or damaged filter head allows fluid to bypass filtration entirely, sending contaminants directly into the engine or fuel system. On equipment ranging from the DAC7000SS diesel generators to B Series walk-behind trowels, keeping this component in sound condition is essential to protecting engine longevity and maintaining clean fluid flow.
