Bosch 1 125 045 107 Scania 2 Series Stator – The Premium Winding Your Alternator Rebuild Demands
Your Scania 2 series alternator rebuild requires the correct stator variant — not just any winding that physically fits. The Bosch 1 125 045 107 Scania 2 series stator is the higher-specification OEM winding assembly for Scania 2 series alternator builds requiring greater output capacity. At £58.99, it costs more than the entry-level variant for good reason. Therefore, fitting this stator means your rebuilt alternator delivers the full output your vehicle’s electrical system was designed to run — not an undersized compromise.
Why Scania 2 Series Alternators Use More Than One Stator Specification
Not all Scania 2 series alternators are the same unit. However, many mechanics make the mistake of ordering the first stator that physically fits — without confirming the correct winding specification for their alternator variant.
The Scania 2 series ran from 1982 to 1991 across multiple chassis and powertrain configurations. As a result, different alternator builds were fitted across the range — each requiring a stator wound to match its rated output. So, the Bosch 1 125 045 107 is the correct replacement for the higher-specification alternator variant in this family. Therefore, always confirm your alternator unit number before ordering — fitting a lower-rated stator into a higher-output alternator housing creates undercharging faults immediately.

How to Confirm You Need This Stator — Not the Lower-Rated Variant
Ordering the wrong stator variant wastes time and creates a fault on first start. However, confirming the correct part takes only two checks before you order.
First, identify your alternator unit number from the housing plate. The unit number tells you exactly which stator specification was fitted from the factory. So, cross-reference that number against Bosch part 1 125 045 107 before purchasing. Furthermore, if your existing stator is physically larger or heavier than a standard replacement, the higher-rated winding variant is almost certainly the correct choice for your unit.
Second, check your vehicle’s electrical load requirements. A Scania 2 series running additional ancillary equipment — refrigeration, hydraulic systems, tail lifts, or auxiliary cab electronics beyond standard fit — needs the higher-output stator to maintain correct charging voltage under full load. Therefore, if your truck has been upgraded since leaving the factory, the premium winding variant protects your battery and electrical systems under sustained peak demand.
What Happens When a Scania 2 Series Runs the Wrong Stator Specification
Fitting a lower-rated winding into a higher-output alternator housing does not cause an immediate failure. However, the consequences build steadily over every working shift.
An undersized stator cannot match the magnetic field strength generated by the rotor at rated speed. As a result, the alternator consistently undercharges — batteries never reach full capacity, voltage drops under load, and dual battery systems on longer-haul Scania 2 series trucks suffer premature failure. So, what looks like a battery problem or a regulator fault almost always traces back to a mismatched stator specification.
Furthermore, an undersized stator runs hotter than it should because it is working beyond its thermal rating to try to meet demand. As a result, winding insulation breaks down faster — and you end up replacing the stator again far sooner than necessary.
Bosch 1 125 045 107 Scania 2 series stator Quality — Built for the Demands of Classic Scania Operation
The Scania 2 series is a classic heavy commercial platform. However, classic does not mean light duty — these trucks worked demanding routes carrying heavy loads for full working days. Therefore, the stator winding must be built to the same standard as the original Bosch factory unit.
The Bosch 1 125 045 107 uses quality copper windings and lamination steel rated for the thermal cycling and sustained electrical loads the Scania 2 series alternator operates under. So, this is not a rewound core or a pattern alternative — it is a brand-new OEM winding that meets the original Bosch specification exactly. As a result, your rebuilt alternator performs to its rated output from the first start and holds that performance across a full working life.
