QU10313 Teflon NV4500 Mainshaft 3rd Bearing Spacer

QU10313 Teflon NV4500 Mainshaft 3rd Bearing Spacer replaces early production steel and late production Teflon 3rd gear bearing spacers in New Venture NV4500 5 speed manual transmissions. QU10313 separates the 3rd gear mainshaft snap ring from the third gear bearing. USA made.

Applications

Tech Note 1: Purpose
QU10313 and QU10314 Bearing Spacers protect the plastic bearing cages from the contacting the sharp, open ends of the adjacent snap rings. In very early production transmissions, the spacers were steel, but to minimize noise, the spacers were switched to a Teflon material.

Tech Note 2: Soak in Oil
Soak the Bearing Spacers in QU90020 NV4500 GL-4 75w85w Manual Transmission Oil or other approved lubricant before assembly.

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 V1003DVD NV4500 Overhaul Video for more information.
