The Multiquip 7750394 Main Bushing.25 43F is a genuine OEM component designed for the RW1403HF roller. Sourced directly from Multiquip, this bushing meets the original design specifications for the application, ensuring correct fit within the drum or drive assembly without the need for secondary modification. Verified fitment covers the RW1403HF, making it a straightforward like-for-like replacement for this RAMMAX roller model.
Key Features
- Genuine OEM Material Grade — Manufactured to the original bore tolerance and hardness spec, which is critical for a bushing that absorbs radial load and resists wear over continuous compaction cycles.
- Direct-Fit Installation — Matches the original bore diameter and seating depth, so it drops into the housing the same way the factory unit does.
- Confirmed Fitment for RW1403HF — Verified for the Multiquip RW1403HF RAMMAX roller; check your model plate before ordering to confirm applicability.
- Load-Bearing Precision — A correctly sized main bushing keeps the shaft centered and rotating smoothly; an undersized or worn bushing introduces lateral play that accelerates shaft and housing wear.
- Verified Multiquip Part Number — Ordered and fulfilled as Multiquip 7750394, eliminating cross-reference guesswork when restocking or submitting a service order.
A main bushing serves as the bearing interface between a rotating shaft and its housing, controlling radial movement and distributing load across the contact surface. In a walk-behind vibratory roller like the RW1403HF, the main bushing supports the eccentric shaft or drum axle under the sustained vibration and downward force of compaction work. When this bushing wears beyond its service limit, shaft deflection increases, accelerating damage to surrounding components and degrading the roller's compaction output.
