These water-resistant starter motors are available for common 4WD applications

4WD enthusiasts love testing their vehicles to the limit, often in remote locations.
If something goes wrong, hours can be spent trying to get the vehicle running again – not to mention the cost of a remote recovery.
OEX explains it has designed and tested an innovative water-resistant starter that handles serious water crossings.
OEX has now released its first water-resistant starter motors for common 4WD applications, with seven units covering 23 applications for 4WD enthusiasts.
The unit is sealed and has a customised drain/breather tube to help prevent water ingress and other contaminants.
OEX has also designed a front seal to protect against the most vulnerable point for possible water ingress.
As a starter heats up, it naturally draws moisture in, so OEX says it is trying to defy the laws of physics with this design, pushing the boundaries of innovation to solve common design and application challenges.
Another recent improvement from OEX includes upgrading the brush holder on 79 and 200 series Landcruiser alternators to avoid premature failure – a particularly vulnerable component due to the low position of the alternator in the engine bay.
When the engine runs, air flows from the rear of the alternator to cool down the rectifier, rotor, and stator.
In wet, dusty, muddy, or off-road conditions, the water, dust, and mud can easily enter the brush assembly through this airflow, leading to brush, brush spring, and slip ring failure.
OEX says its innovation is evident in its design of an alternator with semi-sealed brush holders, which minimises this entry of water, dust, and mud into the brush assembly, preventing premature failure.
Additionally, OEX states it offers two high-output alternators for these applications, with a custom-made upgrade cable, fuse and fuse holder included in the box.
The OEX range is available at Repco and NAPA Auto Parts.
