Main bearings 0.025 Nissan 1986-90 TD25, QD32, ZD30 2289-2494-2663cc DIESEL ACL ACL-5M2965-STD

Main bearings 0.025 Nissan 1986-90 TD25, QD32, ZD30 2289-2494-2663cc DIESEL ACL ACL Race bearings are designed to work in the most extreme conditions and the most demanding engines. The advanced technological process allows the bushing to adapt to the deformation occurring at high revolutions and helps in the formation of hydrodynamic oil films. This technology, combined with the advanced geometry of the bushings, makes them ideal for heavily stressed engines. : STDX -0.025 mm (looser than nominal) STD +0.000 mm (nominal) +0.025 mm (tighter than nominal) +0.25 mm (first shaft grinding) +0.50 mm (second shaft grinding)
