SLOWLY getting everything together. I had to order some shims from McMaster to get the output shaft end play correct. Those are in and the measurement looks good relative to spec. Spec is 0.003 to 0.012, with a target of .006. This ended up at 0.003, so I'm happy. Pulling a 0.005 shim would have resulted in 0.008, so whatev.
Need to install the shaft seal in the tailshaft housing, then break out the anaerobic goo and do the final installation. I have a new rubber splined sealing washer to go on the end of the shaft, after which I can install the yoke and declare that the rear output is complete.
I have a seal for the front output... I should probably just pull the front yoke and install it, but it's not nearly as easy as the rear yoke. It'll be way harder in the car, so on the bench if the obvious place to do it.
I'm deciding whether or not I want to yank the stock vent fitting and tap it for a pipe fitting (and then to A/N plumbing?). It already rotates while installed, so the sealing of the fitting to the tailshaft housing is questionable at best.
Edit: testing fixing images
I'm going to run all the vents from all four gearboxes (trans, T-case, front diff & rear axle) to the PCV system so that I can ford modest water crossings without worry. The road to a friend's house flooded more than I'm comfortable fording in a Fiero a few years back, so I want to be sure an event like that doesn't stop me again.
All Eagles (& a lot of Jeeps?) use a 36 tooth speedometer gear with 3.54 axle ratio. My dad found a guy who had one and bought it. I will probably use a DRAC or the JagsThatRun VSS adapter to provide a VSS signal to the ECU, while retaining the mechanical speedo, for now. I'd like to swap to an electronic speedometer eventually, but the Eagle instrument panel is really hard to remove, so that has to be more carefully considered.
