Dave, you sold me this NP231 w/SYE for the right price. I'm not blaming you for this at all, and I'm quite happy with the price I got, but whoever put this thing together was a chimpanzee of a mechanic. :gee:
They managed to break a chunk off the fluid pump right where the pickup tube goes in, so rather than use an O-ring they gobbed RTV everywhere.
The rear output yoke nut was barely past hand tight.
The extension housing bolts were cranked down to a billiondy foot pounds and one was rounded. I had to use a chisel to spin it free.
The main housing bolts were alternately hand-tight and tightened to a billiondy foot pounds.
They also seem to have interesting ideas on how to apply RTV, both in quantity and application accuracy.
At this point I think I'm just gonna tear the SYE out of it (already did, actually) and put it in the MJ at some point, unless the XJ needs it first. The rest of the case is going in the spare parts pile, if you ever need anything, it's free.
PS: I had no idea that any NP231J was synchronized, thought that was NP241s only. There's a giant brass synchro in this thing on the mode hub.
