Key Features

• Genuine OEM Crankshaft Specification — Manufactured to the exact dimensional tolerances required for correct keyway seating on the crankshaft, ensuring proper torque transfer without slippage.
• Direct Drop-In Installation — Machined to match the original keyway slot profile on EY20 and QP301TA applications, allowing straightforward installation without modification to the crankshaft or drive component.
• Compatible with EY20 and QP301TA Equipment — Confirmed fitment for Multiquip EY20 and QP301TA model platforms, so you can order with confidence knowing this is the correct part for your machine.
• Restores Accurate Shaft Timing Alignment — A worn or missing crankshaft keyway allows the driven component to shift out of timing position, causing poor engine performance or mechanical damage; replacing it promptly restores correct alignment.
• Hardened Material Construction — Built to withstand the rotational stress and shear forces placed on a crankshaft keyway during normal engine operation, providing lasting service life in demanding pump applications.

A crankshaft keyway is a small but critical component that locks a pulley, flywheel, or drive gear into a fixed rotational position on the crankshaft. It fits into a machined slot — the keyway — cut into both the crankshaft and the mating component, preventing any rotational slippage between the two. If the keyway shears or wears, the driven component will shift out of its timed position, which can result in ignition timing errors, loss of power, or serious internal engine damage if left unaddressed.
