Maintain correct gearbox bearing preload and internal alignment with this Genuine Nissan Mainshaft Spacer, designed for early Nissan Patrol GU Y61 models fitted with manual transmissions. This OEM spacer is located on the rear section of the gearbox mainshaft and sits between bearings as part of the internal transmission assembly.

The mainshaft spacer plays a critical role in maintaining correct spacing, gear alignment, and bearing preload within the manual gearbox. If this component is worn, damaged, or incorrectly installed during a rebuild, it can lead to excessive end float, noisy operation, premature bearing wear, or poor gearbox performance.

Manufactured to genuine Nissan specifications, this direct-fit spacer ensures precise gearbox assembly, correct internal tolerances, and long-lasting durability in demanding driving and off-road conditions.
