The Multiquip 4403 is a genuine OEM Tub Frame Assembly designed for a wide range of Multiquip and Whiteman equipment, including light towers, ride-on power trowels, and flat saws such as the LT6KV, JWN24HTCSL, HHN34TVD, HTN28K, HTN27K, SP1G, SP1E16A, and SP2S20H. As a factory-original component, the 4403 is manufactured to the same specifications as the part it replaces, ensuring a direct, hassle-free installation. DHS Equipment supplies this part as an authorized Multiquip OEM replacement, so you can order with confidence knowing you are receiving the correct assembly for your machine.
Key Features
- OEM-Grade Structural Integrity — Manufactured to Multiquip's original design tolerances, delivering the same load-bearing strength and dimensional accuracy as the factory-installed frame assembly.
- Direct-Fit Replacement — Mounts using the original attachment points and hardware interfaces, keeping installation straightforward across compatible models.
- Broad Equipment Compatibility — Confirmed fitment across multiple Multiquip and Whiteman product lines including light tower LT6KV, mechanical trowels HHN34TVD, HTN28K, HTN27K, JWN24HTCSL, HHN31V, and flat saw models SP1G, SP1E16A, and SP2S20H.
- Structural Foundation for Core Functions — The tub frame provides the primary structural housing that supports and aligns internal components; a compromised or damaged frame puts surrounding assemblies at risk and can render a machine inoperable.
- Verified Multiquip Part Number — Sold as part number 4403 directly through DHS Equipment, an authorized Multiquip distributor, eliminating guesswork when cross-referencing your machine's parts diagram.
The tub frame assembly serves as the primary structural chassis or housing enclosure on the equipment it supports. It provides a rigid mounting surface that keeps internal components correctly positioned and protected during operation. When the tub frame becomes cracked, bent, or otherwise damaged, it can cause misalignment of attached components, accelerate wear on surrounding parts, and compromise the overall integrity of the machine — making prompt replacement critical to keeping the unit in safe working condition.
