OEX Alternator 12V 40A Mitsubishi Style RXA200

The OEX RXA200 is a remanufactured 12V 40A alternator in Mitsubishi style, supplied as a twin leg unit with an internal regulator. Key mounting details include an 80mm inside mounting leg measurement, 156mm centre-to-centre mounting, an 8mm pivot hole, and an M8 x 1.25 adjusting hole.

This alternator is listed as suitable for Mitsubishi applications and also appears across a wide range of industrial and equipment uses, including selected Allis Chalmers, Gehl, Hyster, Iseki, Isuzu, Komatsu, Massey Ferguson, Mazda, Nissan, Sumitomo, Takeuchi, TCM, Toro, Yale and Yanmar applications. Because alternator fitment can depend on bracket style, pulley type, shaft dimensions and regulator arrangement, the part number and physical measurements matter just as much as the application list.

The unit uses a 73mm pulley outside diameter with an A pulley section, a 15mm shaft dimension, and weighs 3.64kg. It is sold each and carries a 3 year passenger / 1 year commercial warranty, which gives a useful reference point when replacing an older Mitsubishi-style charging unit in a working vehicle or machine.

Application and Buying Notes

Before ordering, compare the RXA200 part number, the Mitsubishi style housing, and the mounting measurements against the unit you are removing. The key checks here are the 12V system, 40A output, twin leg mount, 80mm inside mounting legs, 156mm mount centre-to-centre, and the 73mm A-section pulley.

The regulator type is internal, so the replacement should match the vehicle or machine’s charging system arrangement. If the existing alternator uses an external regulator or a different wiring setup, do not assume this unit will be a direct replacement without confirming the application and terminals first.

Pulley size and shaft dimensions are important on alternators because belt alignment and pulley fit affect how the unit installs and runs. This unit has a 15mm shaft dimension and a 73mm pulley outside diameter, so it is worth checking the old alternator and belt drive hardware before purchase, especially on industrial and equipment applications where variations are common.

The listing covers a broad range of equipment families, but not every model in those families will necessarily take the same alternator. Matching the physical layout, mounting points, pulley section, and part number is the safest way to avoid ordering the wrong component.

As a remanufactured unit, this alternator is suited to buyers looking for a serviceable replacement rather than a brand new assembly. The 3.64kg weight, internal regulator, and twin leg configuration provide useful comparison points when checking against the removed part or workshop records.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number RXA200 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 80mm, Pivot Hole Diameter 8, Pulley Outside Diameter 73mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 156mm, Shaft Dimension 15.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. RXA200, Brand OEX, Description OEX Alternator 12V 40A Mitsubishi Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR15, Power Rating (Amp) 40, Pulley Section A, Suits Unit Make Mitsubishi.

OEX Alternator 12V 40A Mitsubishi Style. Part number RXA200 should be checked first. Listed voltage is 12. Listed output rating is 40. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number RXA200, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 40 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ALLIS CHALMERS 5020, ALLIS CHALMERS 6140, GEHL SL5620, GEHL SL5625/DX/SX, GEHL SL5625/DX/SX 1994, GEHL SL5625/DX/SX 1995. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment using the RXA200 part number, the Mitsubishi style application, and the measured mounting and pulley details before ordering. Where vehicle or machine fitment is uncertain, compare the removed alternator against the 12V 40A specification, twin leg mount, internal regulator, 80mm inside mounting legs, 156mm centre-to-centre measurement, and 73mm pulley.
