The Multiquip 59027 Woodruff Key 3X6.5 RW 1403 DIN 6888 is a genuine OEM component designed for Multiquip RAMMAX walk-behind roller models including RW1403HF, RW1404, RW1404MR, RW1504HF, RW1810, and the P33/24 FR/FC/FCR and P33/24 HHMR-BD series. Sourced directly from Multiquip, part 59027 meets the same dimensional and material standards as the original, ensuring a correct fit in the drivetrain or engine shaft assembly. Verify your model code and serial number range against the fitment list, as some variants such as the RW1404MR and RW1504HF have serial number breaks that affect applicability. Ordering the exact OEM part number eliminates guesswork and keeps your roller back in service without rework.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the DIN 6888 standard for Woodruff keys, ensuring the 3X6.5 mm profile seats fully and transfers torque without slipping or rocking in the keyway.
- Drop-In Shaft Fit — Matches the original keyway geometry on compatible RAMMAX roller shafts, so installation requires no filing, shimming, or keyway modification.
- Broad RAMMAX Roller Compatibility — Fits RW1403HF, RW1404, RW1404MR, RW1504HF (up to S/N 1534188), RW1810, P33/24 FR/FC/FCR, and P33/24 HHMR-BD with blade — confirm serial number range before ordering.
- Torque Transfer Integrity — A correctly seated Woodruff key locks the drum drive or engine output components in precise rotational alignment; a worn or missing key causes shaft slippage, vibration, and accelerated wear to surrounding components.
- Small Part, Critical Function — At just 3X6.5 mm, this key is easy to overlook during a rebuild, but an incorrect substitute can cause premature keyway damage to the shaft — using the correct OEM specification matters.
A Woodruff key is a small, semi-circular metal key that seats into a curved slot machined into a rotating shaft, locking a gear, pulley, or drum hub to that shaft so they turn together as one unit. On a walk-behind roller like the RAMMAX RW or P33/24 series, this key plays a direct role in transmitting power from the engine or drivetrain to the compaction drum — if it shears, deforms, or falls out, the driven component spins freely on the shaft and the machine loses compaction output entirely. Replacing a worn or damaged Woodruff key promptly prevents the secondary damage that results from metal-on-metal contact between a loose hub and an unprotected shaft.
