Took the rack cap off and moved throttle...nothing. The head of the allen head was approx flush with the pump housing. I gently pushed the rack towards rear of tractor and it moved easily approx 1/4 maybe more to what I would call all the way back. Moving throttle linkage, the rack will not move forward toward radiator nor can I pull it with anything while moving linkage. Any thoughts besides pulling pump and if I need to pull pump, any advice so it can return to appropriate spot?? Happy New Year and many thanks in advance.

I believe it moves forward based o. Throttle setting, so it will only go further than that if the throttle lever is in the open position. If that is the case then something is stuck inside. And the cover is on the back side on those. That means removing the pump to gain access.

If the engine has not set very long, you MIGHT get lucky trying this method. Remove the rack screw and all shims from rack end. Loosen ALL SIX injector line nuts at injectors, and tap the lines to MAKE SURE they are not stuck in the injector due to the Ermeto line ends used as they will be tight. Thread a metric bolt in the rack end to be used as a handle, if I recall it's M6 X 1.0 metric thread. Now, while cranking engine over, pull/push the rack bolt and see if it will move at all BY HAND! If it does begin to move, you are lucky. Keep working with it while cranking engine, it won't start with all the lines loose so don't worry about engine running away. If all six plungers work free, then the throttle SHOULD move rack in/out when all is right. If you do get to that point, replace the rack end screw, leaving off ONE thick shim. Replace the cap, tighten all six injector lines and start engine. If the rack DOES NOT free up pump will need removed for further inspection that can't be done on engine.
