Sounds like a job for a Sweeney Wrench  used on aircraft engines to
loosen and/or tighten the big nut that held the propeller to the
propeller shaft. Certainly didn't want that big prop nut loosening up in
flight.. The Sweeney was a big geared chain drive device that mounted on
the end of the propeller shaft or crank shaft (not always the same in
aircraft engines). It got the job done. I've often wondered if there was
something smaller yet similar when torques get up to where a 180-200 lb
man with a 4-6-8 ft cheater bar wasn't good enough in non-industrial
applications - like our vans.
