A0003250896 Engine Rubber Mounting for Mercedes Benz Truck Spare Parts Axor Actros

A0003250896 engine rubber mounting for Mercedes-Benz Axor and Actros trucks. Hydro-elastic vibration damping mount for front or rear engine support. Direct OE replacement part. No mounting bolts or washers included. Verify mounting position and thread sizes before ordering. Professional installation required.

The A0003250896 is an engine rubber mounting designed for Mercedes-Benz heavy commercial vehicles, specifically the Axor and Actros model series. This mounting is a hydro-elastic component that supports the engine weight while isolating vibration and noise transmission from the engine to the chassis frame. The part number reflects the genuine Mercedes-Benz OE specification for this mounting bracket assembly.

The mounting consists of a metal housing bonded to natural rubber compound. The housing is fabricated from high-strength steel with a corrosion-resistant coating. The rubber compound is formulated specifically for heavy diesel engine applications. It maintains damping properties across a temperature range from -40°C to +120°C. This compound resists degradation from engine oil, diesel fuel, coolant, and road chemicals.

Installation notes for A0003250896 engine mounting. Support the engine with a suitable lifting device before removing the old mounting. Do not let the engine hang from remaining mountings alone. Use a support bar across the chassis rails. Position the support under the oil pan only if a reinforced adapter plate is used. Unreinforced oil pans crack under concentrated load.

Fastener inspection. Remove old mounting bolts. Inspect bolt threads for corrosion or stretching. Replace bolts if any thread deformation is visible. Apply medium-strength thread locker to bolt threads. Torque mounting bolts to manufacturer specification. Typical torque for M12 bolts is 100 to 120 Nm. Typical torque for M14 bolts is 150 to 180 Nm. Overtightening fractures the rubber bond.

Orientation verification. The A0003250896 mounting has a visible orientation mark. Align this mark with the chassis bracket reference line. The hydro-elastic chamber must face the direction of primary engine torque reaction. Reversing orientation reduces damping efficiency by approximately 50 percent. The vehicle may experience cab shake at idle if the mounting is reversed.

Pair replacement recommendation. Replace all engine mountings at the same time. Replacing only one mounting overloads the remaining units. The new mounting provides full damping resistance. The old mounting provides reduced resistance. This imbalance produces erratic engine movement during gear changes. Transmission shift quality degrades. Replace in complete sets for best results.

Post-installation verification. Lower the engine onto the new mountings. Tighten bolts to final torque only with engine at normal ride height. Start the engine. Observe the engine at idle. Visible shaking indicates incorrect mounting orientation or a collapsed opposite mounting. Road test the vehicle. Cab vibration should be significantly reduced compared to the failed mounting condition.

Fluid leak identification. A leaking hydro-elastic mounting leaves a wet stain on the chassis rail. The fluid is clear or light yellow and has a slightly sweet odor. Fluid leakage indicates complete mounting failure. Do not attempt to refill or seal a leaking mounting. The mounting must be replaced. No repair is possible.

Q1: Which Mercedes-Benz trucks use the A0003250896 engine mounting?
A1: This mounting fits Mercedes-Benz Axor and Actros MP2 and MP3 models . Applications include vehicles with OM906, OM926, OM501, and OM502 diesel engines. Verify your original part number before ordering.

Q2: Is this a solid rubber mounting or a hydro-elastic mounting?
A2: The A0003250896 is a hydro-elastic mounting containing glycol-based damping fluid . It is not a solid rubber mounting. The fluid provides additional low-frequency vibration isolation.

Q3: Can I use a solid rubber mounting instead of this fluid-filled one?
A3: No. Solid rubber mountings have different spring rates and damping characteristics. Substituting a solid mounting changes engine movement dynamics. Transmission shift quality and cab comfort degrade significantly.

Q4: How many of these mountings does an Actros truck require?
A4: A typical Actros uses two to four engine mountings depending on chassis configuration . The front engine mountings differ from rear mountings. A0003250896 is typically a rear mounting position component.
