The VOLVO 250328 is a part number that holds importance for mechanics, fleet operators, and heavy‑vehicle enthusiasts because it identifies a specific steering component used in Volvo commercial trucks. While not a consumer vehicle model that you’d see advertised in showrooms, the VOLVO 250328 designation represents an integral part of the steering system in heavy‑duty Volvo vehicles, particularly in various models of the FH and FM series trucks. In this article, we will explore the technical details, applications, features, and practical considerations surrounding VOLVO 250328 to help you understand what this component is, where it fits, and why it matters.
What Is the VOLVO 250328?
The VOLVO 250328 refers to a steering gear assembly sometimes called a steering box or hydraulic steering reducer for heavy trucks. It is an OEM (Original Equipment Manufacturer) part number that Volvo assigns to this specific unit in their parts catalog. This steering gear is a key part of the truck’s steering system: it converts the driver’s input at the steering wheel into controlled movement at the wheels, allowing for safe and responsive handling of large commercial vehicles.
From available technical listings, the component described by the VOLVO 250328 number is clearly a steering mechanism compatible with several Volvo truck models, especially within the FH (Forward control High entry) and FM (Forward control Medium entry) series of trucks dating back many production years. basparts.com+1
Compatibility With Volvo Trucks
One of the most important aspects of VOLVO 250328 is its compatibility across different truck models and production years. This versatility is one of the reasons the part might be encountered in used markets, repair shops, and logistics operations where older Volvos are refurbished.
According to detailed parts listings:
- The steering gear associated with VOLVO 250328 fits various generations of Volvo FH trucks, including those produced from the early 2000s through later model years. basparts.com
- It also fits Volvo FM series trucks across similar production spans. basparts.com
These compatible models represent a broad family of heavy‑duty trucks used for long‑haul transport, construction, and other commercial tasks. The ability of VOLVO 250328 to fit multiple iterations of these vehicles simplifies parts inventory management and makes it more attractive for fleet maintenance.
Physical and Technical Specifications
While precise engineering documentation from Volvo’s official service manuals would offer the full technical specification, several key measurements and characteristics are publicly available from aftermarket and used parts listings:
- Dimensions: The steering gear assembly with the VOLVO 250328 label typically measures around 62 cm in length, 42 cm in width, and 40 cm in height when listed for sale in parts depots. basparts.com
- Weight: The unit weighs approximately 50 kg, reflecting its robust construction necessary for heavy truck steering loads. werktuigen.nl
- Hydraulic Operation: The steering gear is designed to work with vehicles that use hydraulic power steering systems. These systems use pressurized fluid to assist the driver in turning the steering wheel, which is especially important in heavy‑duty commercial vehicles. kmotorshop.com
- Mounting Configuration: Steering gear units such as the one identified by VOLVO 250328 typically include multiple mounting bores and are designed to be installed on the left side of the steering mechanism for left‑hand drive vehicles, which is standard in many markets. kmotorshop.com
The durability and engineering behind this part reflect how truck manufacturers like Volvo design steering systems capable of controlling vehicles that can weigh tens of tons when fully loaded.
Function in Truck Steering Systems
The steering gear represented by the VOLVO 250328 component number functions as the mechanical interface between the steering wheel and the steering linkage connected to the truck’s wheels. In practical terms:
- The driver rotates the steering wheel.
- Through the steering column and associated components, this motion is translated into a controlled movement at the steering gear.
- The gear’s internal mechanisms, often assisted by hydraulic pressure, amplify and convert that motion to push and pull on the tie rods and axle steering linkages.
- This results in the truck’s front wheels pivoting left or right.
In heavy‑vehicle applications, this system must be robust enough to handle large steering loads, return feedback to the driver, and perform reliably over thousands of hours of operation.
OEM Numbers and Interchangeability
In parts catalogs and listings, you may see the VOLVO 250328 number referenced alongside several other codes. These can include:
- Other Volvo part numbers such as 85000088, 7400250328, and similar references in product listings. autoline.kz
- Equivalent codes used by component manufacturers, such as ZF or BOSCH reference numbers, which indicate that the part can be sourced from or remanufactured by other reputable suppliers. kmotorshop.com
This interchangeability is useful in aftermarket parts markets where a mechanic might replace a worn hydraulic steering gear with a remanufactured or compatible alternative that fits the same mounting points and functions identically in service.
Buying and Replacement Considerations
When acquiring a VOLVO 250328 steering gear assembly, there are several practical things to consider:
- New vs Used: Many parts listings show used or refurbished steering units, often salvaged from decommissioned trucks. A used VOLVO 250328 unit might be significantly cheaper than a brand‑new OEM part, but it’s essential to examine condition, wear, and any potential leaks or damage. werktuigen.pl
- Remanufactured Options: Some suppliers offer remanufactured steering gears with warranties and reconditioned components from reputable manufacturers like BOSCH. kmotorshop.com
- Fitment Verification: Always verify that the part number matches the specific model and year of your truck. While VOLVO 250328 fits several FH and FM variants, small differences in steering geometry or chassis specifications can matter.
- Professional Installation: Given the importance of steering systems to vehicle safety, installation by experienced technicians with the proper tools and alignment equipment is strongly advised.
Real‑World Use and Market Presence
Listings for VOLVO 250328 components on various online marketplaces and parts dealers show that this steering gear remains in circulation across Europe and other regions. Used truck parts sellers list the unit with clear indications of its dimensions and original part codes, supporting the notion that VOLVO 250328 continues to be relevant for maintenance and rebuilds of older Volvo FH and FM trucks. truckscout24.it
Interestingly, VOLVO 250328 also appears in some automotive salvage listings not just as a part number, but even as a reference in sales ads for accident‑damaged trucks where the reference number is used to identify inventory. This reflects how part designations become shorthand for specific assemblies within large fleets and salvage operations. europe-camions.com
Conclusion
The VOLVO 250328 steering gear assembly is a critical steering component for heavy Volvo trucks. While it may not be a consumer‑facing model like a passenger car, its role in the safety and drivability of commercial trucks cannot be understated. Across its lifecycle, from manufacturing through service and eventual reuse, the VOLVO 250328 part serves as a practical example of how technical specifications, compatibility, and quality influence heavy‑duty vehicle performance.
