Applications

Tech Note 1: Lube
Lubricate the seal lip with petroleum jelly before final assembly.

Tech Note 2: Direction of Seal
Install seal so the flat side of the steel seal shell will be facing the transfer case.

Tech Note 3: Earlier Transmissions
A transmission rear output seal is not used on 1992 and 1993 Dodge gas trucks with the NV4500. Also, NV4500 conversions replacing the Getrag G360 in 1989-1993 Diesel trucks do not use a transmission rear output seal. Instead, our TK10517 double lip Transfer Case Input Seal is used.

Tech Note 4: Seal Placement
QU10123 Seal gets pressed into your transmission tail housing. The lip of the seal will contact the transfer case input shaft.

Tech Note 6: Lubes/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.
