Applications

Tech Note 1: Lubricate
Apply a thin film of sealant such as S64000 Sleeve Locker to the stem before installing the vent into the case hole.

Tech Note 2: Fitting
QU11092U has a stub diameter of approximately 0.371". It is a press fit into approximate 0.365" diameter vent holes in most New Process and New Venture transmissions and transfer cases. The press fit is usually adequate to retain the vent fitting, but I like to put some S64000 Sleeve Retainer on the stub before pressing it into the housing. On some applications, you can also slightly expand the inboard end of the stub if it protrudes past the inside of the case. The barbed end of QU11092U is made to fit 5/16" inside diameter hose.

Tech Note 4: New Venture, New Process, Magna
When Ford (1999 models) and Dodge (2003 models) first used NV271 and NV273 transfer cases, New Process Gear (NPG) of East Syracuse N.Y. was part of New Venture Gear (NVG). When NVG dissolved, NPG continued on under Chrysler. Chrysler subsequently sold the production rights to Magna, a Canadian automotive parts company. All these name changes are confusing, but the important thing to know is a specific assembly number for any 271F, 271D, 273D, and 273F transfer case is the same and uses the same replacement parts regardless if it was built by New Venture, New Process, or Magna.

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 VSG1003DVD NV4500 Overhaul Video for more information.
