Tried to answer your earlier post but had network problem accessing this BB.
Your 6U7422 is a 1953 model (although some id lists vary)
Yes, you change all four filters at once. There are two bleed valves on the filter housing, one below the filter deck (facing out) and one above (knurled knob facing forward). You can save yourself a lot of cranking if you top off the filter housing with diesel while changing the filters before you close it up. Bleeding injector pump and/or injectors has already been covered.
The rack should travel it's full range with throttle fully open. Very common to have them stick on an infrequently used unit. With the cover off, squirt some WD40 or your favorite while manually moving the rack. You'll know when it is free. The throttle action is through spring loading so there is no direct mechanical connection.
Most of the Cat nuts hang out on the ACMOC (Antique Caterpillar Machinery Owners Club) bulletin board. You will have to register www.acmoc.org and screening for scammers takes a little time but it is free.

Also if you post here I think you would get better response under the crawler tractor section.
Good luck with your kitty.
