Tech Note 1: Removal/Installation
This Bushing gets pressed into the back of your 4x2 rear output housing. If the housing is off the transmission, use QT2044 and a QT1100 series Driver Handle to press out the old bushing and press in the new one. We do not make tools to change these thinwall bushings in the vehicle.

Tech Note 2: Installed I.D.
The installed inside diameter will be just over 2.2".

Tech Note 3: NV4500HD
New Venture NV4500HD 5 speed manual transmissions were used in 1994-2004 era Dodge Ram 2500 and Ram 3500 trucks with either the gas V10 or 5.9L Cummins Diesel engine.

Tech Note 4: Fits
QU10025 fits NV5600 and NV4500HD 4x2 transmissions. It will NOT fit 1994-2005 Dodge Ram NV4500LD transmissions used in trucks with gas V8 engines.

Tech Note 6: 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.
