The Multiquip 502018 Housing Jackshaft is a genuine OEM component designed for MC-42S, WC-42S, and EC-42S concrete mixers. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory, ensuring a proper fit with no guesswork. It is confirmed compatible across the 42S mixer platform, covering the Multiquip, Whiteman, and Essick model variants in that series. When you need an accurate, like-for-like replacement, the part delivers the confidence that only a genuine OEM part can provide.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material specifications as the original jackshaft housing, ensuring structural integrity under the torsional loads of a working drum drive.
- Direct Bolt-In Replacement — Matches the original mounting footprint and shaft bore dimensions of the 42S mixer platform, allowing straightforward installation without custom fitting or machining.
- Broad 42S Platform Coverage — A single part number covers the MC-42S, WC-42S, and EC-42S concrete mixer models, simplifying parts procurement across your fleet.
- Maintains Drive System Integrity — A correctly fitted jackshaft housing keeps the intermediate shaft properly aligned, protecting gears, bearings, and the drum drive from accelerated wear caused by misalignment.
- Verified Multiquip Part Number — Ordering by part number 502018 removes compatibility uncertainty and ensures you receive the exact housing spec for these mixer models.
The jackshaft housing is the structural enclosure that supports and positions the intermediate (jackshaft) shaft in the mixer's drivetrain. It holds the shaft in precise alignment between the engine and the drum, transmitting rotational power efficiently while keeping internal components protected from debris and contamination. When the housing cracks, wears at the bore, or becomes damaged, shaft misalignment follows — leading to accelerated gear and bearing wear, increased vibration, and eventual drivetrain failure if left unaddressed.
