Countershaft stuck!!!NP435
Hello all, I’m a new member here, asking all NP435 guys. My countershaft in my NP435 Ford F-100 will not spin when I put the new thrust washer on the front and fit the tabs to the grooves on the actual transmission, what’s going on? Is the washer to thick? If I completely assemble it without the thrust washer it spins freely, but if the thrust washer is put in place and I tighten it back together nothing it seizes, any ideas would be great!

It is the thrust washer labeled 7119 at the lowest cluster on the left side of the schematic of the transmission, I know for a fact that it is an NP435. But everything seizes once i get it all tightened down. But if I leave the 7119 thrust washer out, it spins freely all tightened down

Not sure if it helps, but here is a link to the relevant section of the service manual...
