Multiquip 1584151360 Air Breather Screw

The Multiquip 1584151360 is a genuine OEM Air Breather Screw designed for Multiquip diesel welders and super-silent diesel generators including the DLW300ES, DLW400ES, DAC7000SS, DAC7000SSA, DAC7000SSW, DA7000SSA2, and DA7000SSA2GH series. As a factory-original component, it is manufactured to the exact specifications required by these machines, ensuring a correct, trouble-free installation every time. Sourced directly through authorized Multiquip supply channels, part 1584151360 is the same screw that ships on new equipment — no guesswork, no fitment uncertainty. If you are servicing or rebuilding the air breather assembly on any of the compatible models, this is the correct replacement part to specify.

Key Features

• Factory-Original Construction — Manufactured to Multiquip OEM standards, with correct thread pitch, material grade, and sealing geometry specific to the air breather assembly on these machines.
• Direct-Fit Replacement — Installs directly into the air breather mounting position on compatible DLW and DAC/DA series equipment with no reworking or adaptation of the surrounding hardware.
• Broad Series Coverage — Confirmed fitment across the DLW300ES, DLW400ES, DAC7000SS, DAC7000SSA, DAC7000SSW, DA7000SSA2, and DA7000SSA2GH models in a single part number.
• Crankcase Ventilation Integrity — A correctly fitted air breather screw maintains a properly sealed and vented breather system, preventing pressure buildup and contamination ingestion that can accelerate engine wear.
• Fuel and Emissions System Compliance — On diesel generators and arc welders, maintaining an intact breather system is critical to correct crankcase pressure management and emission compliance during operation.

The air breather screw secures and seals the air breather assembly on the engine crankcase, allowing controlled venting of crankcase pressure while keeping contaminants from entering the oil system. Without a properly seated and undamaged breather screw, the crankcase can build excessive pressure or draw in unfiltered air, both of which degrade engine oil and accelerate internal wear. On diesel-powered welders and generators like the DLW and DAC series, where extended run times are common, keeping this small but critical component in good condition protects the engine over the long haul.
