Shop Now for 2003-2005 Dodge Ram 2500, Ram 3500 New Venture NV4500 Manual Transmission Bearings and Bushings. The New Venture NV4500 standard transmission uses a combination of flat, needle, straight roller, taper roller, and thrust bearings. All these bearings are available separately as needed.
The NV4500 Transmission uses Timken® tapered roller bearings for the Input/Output shaft, Mainshaft, and Countershaft. Of the 8 part cup and cone part numbers, six are high-performance versions of standard size bearings. These high-performance bearings can be identified by a suffix letters following the base number stamped or etched in each part. Due to the extreme loads imposed on the transmission, both the diesel and gas engines are beyond the engineering parameters of standard series bearings. Thus, using the original equipment Timken® bearing numbers is mandatory for a long-lasting overhaul. The bearings we supply, both individually and in our Torque King® Kits are the exact Timken® part numbers as originally specified by New Venture.
Early versions of the NV4500 transmission used needle roller bearings with metal cages. Due to customer complaints of the noise, New Venture switched to Torrington and Luk plastic caged bearings for everything except first design reverse idler bearings and the flat QU10134 Thrust Bearing. Our needle bearings are either the exact original equipment numbers specified by New Venture or current production replacements. Unlike all the NP435 and SM465 4 speed transmissions it replaced, NV4500 gears rotate on bearings instead of bushings or direct fit gears. With bearing supported gears, NV4500 transmissions can be operated in vocational applications for long periods in low gears without damage to the gears or shafts. NOTE: the Reverse Idler Bearings for 1994-1996 are NOT interchangeable with the 1997-2002 Reverse Idler bearings.
