The Multiquip 21591 Reduction Case Gasket is a genuine OEM replacement designed for Whiteman WM70S/P mortar and plaster mixer models. This is an authentic Multiquip part, manufactured to the same specifications as the original, ensuring a correct fit within the reduction case assembly. Sourced directly through authorized Multiquip distribution, the 21591 is the recommended replacement when the original gasket shows signs of wear, compression failure, or oil seepage around the reduction case.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original gasket profile and material spec, delivering the compression and chemical resistance needed to contain reduction case lubricants without weeping or degrading.
- Drop-In Fitment for Whiteman WM70S/P Mixers — Matches the original bolt pattern and case mating surface exactly, so disassembly and reassembly follow standard service procedures without adjustment.
- Protects Reduction Case Internals — A properly seated gasket keeps gear lubricant in and contaminants out, directly supporting the longevity of the gears and bearings inside the reduction case.
- Stops Oil Seepage at the Source — A failed or flattened gasket is a common cause of oil loss and external contamination on mixer drivetrains; this replacement addresses the root cause rather than masking it.
- Genuine Multiquip OEM Part — Backed by Multiquip's parts program and sold through authorized channels, so you receive an unmodified, verified component with full traceability to part number 21591.
The reduction case gasket forms a sealed interface between the mating surfaces of the mixer's reduction case housing. Its job is to prevent gear oil from escaping the case while also blocking dirt, water, and abrasive material from entering — both of which are constant hazards in mortar and plaster mixing environments. When this gasket deteriorates or is compromised during a service, oil loss accelerates wear on internal gears and bearings, and contamination can lead to premature drivetrain failure. Replacing it at the first sign of leakage is a straightforward step that protects a far more costly assembly.
