Ugh. Due to various reasons my Ford 4500/753 TLB sat for what appears to be "too long" - I got it started the other day and found the crowd control was completely unwilling to move - that's the control valve mechanism, (which is verified as "free to move up to the actual control valve actuator") not the cylinder (as far as I know, so far.)
This particular lever is the only one of the 6 that's evidently been broken and welded in the past, so clearly "just wail on it" is the wrong answer. The other 5 all work/move.
I got the housing off, kicked out a mouse-nest, and sprayed PB-Blaster on the exterior of the control valve, not that I expect miracles from either PB-B or Kroil (available, but the PB-B was easier to lay hands on) despite their marketing departments.
Where to go next?
