Replacement alternator pivot bolt measuring 5/16" UNF x 5" (125mm) for a wide range of Leyland and Marshall tractors.
This bolt forms the main pivot point for the alternator, allowing it to swing when adjusting the fan belt tension before being secured in position.
The alternator pivot bolt provides the fixed mounting point that allows the alternator to rotate when adjusting the fan belt. Over time, the bolt can become worn or corroded, particularly if it has been removed several times during belt or alternator replacement.
A worn pivot bolt can allow unwanted movement of the alternator, making it difficult to maintain the correct fan belt tension and potentially causing belt misalignment or premature belt wear. When replacing the pivot bolt, it is also worth checking the condition of the mounting brackets, spacers and adjustment link to ensure the alternator remains correctly aligned.
This bolt has a 5/16" UNF thread and an overall length of 5 inches (125mm), matching the original specification for the applications listed.
Ideal for customers searching for 53K1820 alternator bolt, alternator pivot bolt, 5/16 UNF alternator bolt, 125mm alternator bolt, Leyland alternator mounting bolt, Marshall alternator bolt and classic tractor alternator mounting hardware.
