Applications

Tech Note 1: Inspect for Wear
The thick, cast iron 3rd Gear Thrust Washer used in the NV4500 transmission should be replaced if there is ANY evidence of wear on the thrust face.

Tech Note 2: Steel Locating Pin
One of the two tiny, hardened steel pins in optional QK1110 Locating Pin Kit goes in a hole bored in the mainshaft. The pin will protrude enough to fit the narrow slot in the inside diameter of QU10302 Mainshaft 3rd Gear Thrust Washer. This Pin, which should be replaced during any major transmission service job, keeps the Thrust Washer from rotating on the shaft.

Tech Note 3: Before Installation
Lubricate the Thrust Washer with clean QU90020 NV4500 Transmission Oil before installation.

Tech Note 5: 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 V1003DVD NV4500 Overhaul Video for more information.
