Help!
I have gotten to the point of reassembling the 420. I have reinstalled countershaft, idler shaft and mainshaft (and all their gears). Now, when I reinstall the clutch shaft, everything goes in smooth (as per the manual) but when installed, the whole thing is locked and won't turn. I've tried shifting into neutral, different gears, nothing. It just sits there and won't turn.
Possibly I have frigged something up with the 3rd and 4th speed clutch hub and clutch keys? I've tried frigging around with them, but no joy.
I've completely gone back to scratch many times, all with the same result at the end. I've field stripped this *&^%$% thing so many times I think I can do it blind folded now. I just got so frustrated I was tempted to just beat the hell out it with the BFH (I'm not joking) so I quit for the evening. I'm getting tired of this.
Somebody please tell me what the hell I'm screwing up here? Or walk me through the clutch shaft reinstallation sequence because that's probably where I'm screwing it up.
Thanks,
John
Tell me again why I love old trucks????
