IH 574 shifting into 4th gear problem

I didn't post this question into the right forum apparently. Oh well, call me a newbie to the site!
I have an IH 574 with the usual parking brake problem, but now know how to fix that. However, shifting into 4th gear is a "black art" to say the least. It will always grind horribly as if the gear was missed, whether stopped or moving, forward, neutral or reverse. Rolling with constant engine speed sometimes is successful. When I do manage to get it into 4th, it operates properly with no noise. I have adjusted the linkages but start to throw out the other gear alignments as I try to stretch for more rod to get into 4th. Does anyone have any suggestions?
 
Hi, have you checked the clutch adjustment that the
release bearing is actually disengaging the clutch?
Also the pilot bearing could be seizing and keeps
the transmission shaft turning. I know the gears 1-
2-3 have synchronizers but not sure about 4th.

4th gear is synchronized. Try giving the lever a
little "twist" as you shift into 4th gear also back
the rpms down as you shift. Sometimes double
clutching helps. We has a 574 that I used to haul
silage wagons with. Lotsa road miles, so I got the
hang of shifting that ol girl pretty well.
