Multiquip 1946188132 H/M Gear Case Gasket

The Multiquip 1946188132 is a genuine OEM H/M Gear Case Gasket designed for DA7000SSA2, DAC7000SS, and DLW300ES series diesel generators and light welders. As a factory-sourced component, this gasket is manufactured to the same specifications as the original part, ensuring a proper seal at the gear case interface without the need for adjustment or trimming. Confirmed fitment spans the DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSA, DAC7000SSW, and DLW300ES / ESA / ESA1 models, making 1946188132 a direct drop-in for qualifying units. Sourced through DHS Equipment as an authorized Multiquip parts distributor, this is a straightforward like-for-like replacement backed by OEM provenance.

Key Features

• OEM-Grade Sealing Material — Manufactured to the same compression and material grade as the original gear case gasket, maintaining a leak-free seal under operating conditions.
• Direct Drop-In Fitment — Profile and bolt-pattern match the gear case housing exactly, allowing a clean installation against the mating surface without cutting or shimming.
• Broad Series Coverage — Fits DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSA, DAC7000SSW, and DLW300ES / ESA / ESA1 units from a single part number.
• Protects Gear Case Integrity — A correctly seated gear case gasket prevents oil migration and contamination ingress at the housing joint, keeping internal gear and bearing surfaces properly lubricated.
• Genuine OEM Part — Sourced directly from Multiquip, part number 1946188132 carries full OEM traceability and is the same component used in original assembly.

The H/M gear case gasket forms a precision seal between the two mating halves of the gear case housing on diesel generator and welder-generator units. Its role is to prevent gear oil from leaking out of the case and to stop external contaminants from entering, both of which are critical to the longevity of the gears and bearings housed inside. When this gasket deteriorates, compresses unevenly, or is damaged during service, oil leaks and contamination can accelerate internal wear and lead to gear case failure if left unaddressed.
