Product Overview

The 2470900 is a heavy-duty brushless alternator delivering 24V output at 150A with a 10PK multi-groove pulley, engineered for Scania trucks, buses and coaches. This unit, cross-numbered as 2448165 and 2853479, matches the original charging-system specification for the Scania 24V electrical platform. The Scania branding is visible on the unit housing.

Fitted with a high-precision built-in electronic voltage regulator with overvoltage and breakdown protection, this brand-new alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 150A output provides stable idle charging performance and meets high electrical load demands.

Key physical specs: net weight 10.0 kg, gross weight 11.05 kg, overall dimensions 350 x 310 x 260 mm, supplied inside neutral kraft inner carton.

The Scania 24V Charging Platform and Heavy-Duty Alternator Technology

Scania heavy-duty trucks, long-distance tractors, coaches and buses run 24V electrical systems with factory-spec brushless alternators. The alternator numbering spans the Scania OE numbers (2470900, 2448165, 2853479, 2905972) and the Bosch-format numbers (0518064, 1442788, 063535550080), all referring to the same charging-system family.

Key design features of this unit translate directly into benefits for commercial operation:

• Brushless excitation: no brush wear means maintenance-free operation over a long service life, ideal for high-mileage fleet use.

• High-speed wear-resistant double bearing: reliable operation under sustained engine vibration and high ambient temperatures.

• Pure copper winding: high conductivity with low heat generation and burnout resistance, delivering stable charging under heavy electrical loads.

• Die-cast aluminum alloy housing: lightweight yet shock-resistant and corrosion-resistant for harsh road conditions.

• Factory inspection: pressure resistance, load, aging and dynamic balance tests before dispatch ensure consistent quality.

It is critical to verify the pulley groove count on your old alternator: this unit uses a 10PK multi-groove pulley. Confirm the rated output (24V 150A), rotation direction (CW) and mounting bracket spacing against your original alternator before ordering. Always cross-check the OE numbers stamped on your old unit, including the Scania 2470900 family, before placing an order.

Technical Specifications

Compatibility and Cross Reference

This alternator fits Scania heavy-duty trucks, long-distance tractors, coaches and buses. Do not rely solely on the brand name for fitment validation; always compare the original part number, rated output, pulley groove count, rotation direction and mounting bracket spacing before ordering.

Multiple Scania and Bosch-format OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 2470900 serves as a direct drop-in replacement.

What to Look for in a Replacement

Follow these five verification steps before placing your order to avoid wrong-part returns:

• 1. Check the voltage and rated output on your old alternator: confirm it is rated for 24V 150A. Other ratings are not interchangeable.

• 2. Count the pulley grooves: this unit uses a 10PK multi-groove pulley. Alternators with a different pulley configuration are incompatible.

• 3. Confirm the rotation direction: this unit is clockwise (CW). A counter-rotating alternator will not charge correctly.

• 4. Compare the mounting bracket spacing, terminal positions and connector configuration with your original alternator, and match OE numbers including the Scania 2470900 family.

• 5. Weight cross-check: genuine matching unit weighs approximately 10 kg net; significant weight difference indicates wrong assembly.

Application Scenarios

• Heavy-duty truck and bus repair shops servicing Scania trucks, tractors, coaches and city buses across Europe, the Americas, Asia-Pacific, Africa and the Middle East.

• Commercial fleet operators maintaining original-spec charging systems on Scania vehicles in long-haul operation.

• Auto parts exporters and distributors stocking 24V heavy-duty alternators for the European commercial vehicle market.

• Used commercial vehicle traders refurbishing pre-owned Scania trucks and buses for global secondary markets.

• Cost-conscious buyers looking for a reliable new alternator at a competitive price.

FAQ

Q: Which vehicles does this alternator fit?
A: It fits Scania heavy-duty trucks, long-distance tractors, coaches and buses, including the Scania 4 Series, P/G/R/T Series and large passenger, touring coach and city bus models. Confirm your vehicle and OE number before ordering.

Q: My old alternator shows OE number 2448165 or 2853479, will 2470900 work?
A: Yes. These numbers belong to the same alternator family for the Scania 24V platform, differing only by production revision and market specification. It serves as a direct replacement.

Q: Can I fit this alternator onto other truck brands?
A: No. Different manufacturers use different alternator mounting brackets, pulley configurations and terminal layouts. Confirm your vehicle before ordering.

Q: The alternator does not charge the battery fully, what should I check?
A: Check the belt tension, the alternator wiring connections (B+ and D+ terminals) and the condition of the battery and voltage regulator. A multimeter test at idle should show charging voltage around 27-28V on a 24V system.

Q: What is the difference between this brushless unit and a brush-type alternator?
A: This unit uses brushless excitation, which eliminates brush wear and reduces maintenance over the service life, making it better suited to heavy-duty commercial operation.

Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 12-month (1-year) warranty applies from installation date; warranty excludes damage caused by mis-installation, incorrect wiring, water ingress, short circuit or physical damage.

In Practice

For technicians working on Scania 24V electrical systems: Before removing the existing alternator, confirm the engine is off and the battery is disconnected at the negative terminal first, and isolate any live electrical or hydraulic equipment. Remove the battery cable from the B+ output terminal of the alternator, noting the correct orientation of each connection, and label or photograph the wiring before disconnecting.

Loosen the mounting bolts and the belt tensioner, remove the drive belt from the pulley and lift the alternator from its bracket. Compare the new alternator against the old unit: verify mounting bracket spacing, the 10PK multi-groove pulley, terminal positions and connector configuration. Fit the new alternator, route the drive belt over the pulley, and tension the belt to factory specification so that deflection is within the specified range. Reconnect the B+ battery cable and the regulator sense and warning lamp connections, ensuring terminals are clean and tight.

After installation, reconnect the battery and carry out a charging test: with the engine running at idle, the charging voltage should rise to approximately 27-28V on the 24V system and remain stable as electrical load is applied. Confirm the charge warning lamp extinguishes after engine start. Inexperienced mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop.
