Tech Note 1: Timken Bearings
Six of the eight taper bearing numbers used by New Venture in the NV4500 transmission are Timken® high performance parts. While these bearings and cups are dimensionally the same as standard bearing numbers, the materials and finish are superior. The countershaft and input taper bearings/cups included in our Kits are the exact, high performance Timken® numbers specified by New Venture. These bearings can be identified by a one or two letter suffix after the base bearing part number. It is important to use the correct bearings in your NV4500 transmission as substituting standard bearings for high performance bearings will reduce the torque rating and longevity of your transmission.

You will need some special tools to correctly service your NV4500 Transmission. The chart below lists our current NV4500 Special Tools for popular models.

Tech Note 4: Lubricants, Sealants, Threadlockers
Early production NV4500 Transmissions used an anaerobic sealant (QU90003) to seal between the main case and input bearing retainer, top cover, and rear housing. Mid-production units used anaerobic sealant just on the input retainer and RTV for everything else. Later production transmissions used black RTV Sealant (QU90006 or QU90005) for everything. Either type of sealant works fine (except the PTO covers ALWAYS should be sealed with RTV), but I prefer RTV for all components. Regardless of which sealant you use, make sure excess sealant does not block the lube access hole at the top of input retainer pilot that fits into the transmission case! Also, the threaded holes in the main case for the four retainer bolts and 12 PTO bolts are open ended, so you must use new bolts with factory applied threadlocker or apply Threadlocker (S24200) to your existing bolts to prevent oil seepage past the bolt threads. See my TM1003 NV4500 Shop Manual or VSG1003DVD NV4500 Overhaul Video for more information.
