The Once and Future 712...(or: Witches Hat Brew?)
When I bought the 712, the only major problem I knew about was an exhaust leak. While changing out the header, I broke an exhaust stud, the most inaccesable one. Figures...
Then I realized the clutch was slipping, and the engine was drooling copious quantities of oil all over the driveway. Somewhere in there I realized the clutch was slipping, and found that the center tube was full of oil. All in all it added up to a major disassembly and restoration.
Here is the guts of the 712 on some pallets:
Next I need to build a stand for the engine to give it a work-over. Hopefully that includes enough motivation for an EFI conversion:
I expect to get a lot of use from my blasting booth:
And my daughter has found an unexpected use for the 710 winch bumper:
Meanwhile, the connection between the transfer case and the center tube burped out a pint or so of oil, making me think that I need to rework the transfer case as well as the transmission (wobbly input and output shafts) as well as the clutch.
Anyway, the transfer case witch's hat dumped quite a bit of oil when separated:
Leaving quite a bit of oil in the central tube:
Given that all I was expecting was broken 4x4 locker and an exhast leak, the 712 has been a hot bed of surprises!!!

ka,
I bought it just before Christmas '08 from a seller in California. As is. All I have done with it is drive it home, realize it needed a lot of work, and take it apart.
As P.T. Barnum has been credited, "There's a Sucker Born Every Minute." I think I have earned enough points to be the sucker for my entire day of birth!!

No rocket science with lightening and balancing the drive shaft. (yes it appears from the picture this has been done.)
#1 - Remove the end caps.
#2 - Remove the inner shaft.
#3 - Tig the endcaps back onto the shaft.
#4 - Dynamically balance the assembly.
#1,2 a monkey can do. #3 - Requires some skills. #4 - Requires some fixtures including the end shafts, and the ability to put the unit on a balancing machine. (not the normal do it yourself fare.)
Well worth it when done.
Cheers,
Scott
