Multiquip 04023110 Stub Shaft SAE with Key

The Multiquip 04023110 Stub Shaft SAE with Key is a genuine OEM component designed for MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D series equipment. As a direct OEM replacement, this stub shaft is manufactured to the same specifications as the original part, ensuring a proper interface between rotating drive components. Verify your model and serial number against the fitment data before ordering to confirm compatibility with your specific unit.

Key Features

• Genuine OEM Construction — Manufactured to the same material and dimensional tolerances as the original, ensuring correct torque transmission and keyway alignment across supported models.
• SAE-Standard Shaft with Integrated Key — The SAE profile and included key allow the shaft to seat and lock precisely into mating drive components without secondary machining or fitting.
• Broad Cross-Equipment Fitment — Compatible with MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D machines, covering reversible plate compactor, trash pump, and power trowel applications within the Multiquip lineup.
• Drive Integrity Under Load — A correctly installed stub shaft maintains positive rotational engagement between the engine or motor output and driven assemblies; a worn or damaged shaft introduces slop, vibration, and potential drive failure.
• Direct OEM Sourcing — Supplied as a genuine Multiquip part through DHS Equipment, so you receive the correct specification without substitution or adaptation.

A stub shaft is a short, precision-machined shaft segment that bridges the power output of an engine or motor to a driven component such as a pump impeller, compactor exciter, or trowel gearbox. The SAE designation refers to the standardized shaft diameter and keyway profile, which ensures a secure, non-slip connection when the key is seated in the mating keyway. When a stub shaft wears, corrodes, or the keyway becomes damaged, the driven component loses positive engagement — resulting in slippage, irregular operation, or complete loss of function in the connected assembly.
