The Multiquip 0641400520 Split Pin Dia. 4 x 30 is a genuine OEM fastening component designed for QP-301TY and QP-301TA trash pump models.

DHS Equipment stocks this part to help keep your Multiquip trash pump running without unnecessary delays.
Key Features
- Genuine OEM Material Spec — Manufactured to Multiquip's original dimensional and metallurgical requirements, ensuring the pin shears, retains, or locks at the correct load threshold for this trash pump application.
- Exact Dimensional Match — The 4 x 30 mm profile installs into the OEM-spec bore without filing, bending, or improvising, maintaining proper component retention throughout the assembly.
- Confirmed Trash Pump Fitment — Validated for QP-301TY and QP-301TA trash pumps; using the correct Multiquip 0641400520 eliminates guesswork when sourcing a direct replacement.
- Retention Integrity — A correctly sized split pin locks shafts, pins, and clevis connections securely in place; an undersized or worn pin risks component walk, misalignment, or unexpected separation under load.
- Small Part, Critical Role — Split pins are a common service item during pump teardowns and reassembly; keeping the OEM-spec version on hand prevents assembly holdups during routine maintenance.
A split pin — also called a cotter pin — is a simple but essential fastener used to secure shafts, axle pins, and clevis connections within mechanical assemblies. It works by passing through a drilled hole and bending its legs outward to lock the mating component in position, preventing axial movement or accidental disassembly. When a split pin is deformed, corroded, or incorrectly sized, it can fail to hold its mated component in place, leading to accelerated wear on surrounding parts or loss of mechanical control within the pump assembly.
