This doesn't have to pertain to just a 77, that's just what I'm working on - you gurus out there...
What exactly causes the transmission to whine? Some are very quiet and others are pretty noisy. I know this is relevant to the amount of wear in the transmission. I guess what I'm asking, is where specifically is usually the most noise coming from? Ring and pinion wear? Somewhere else? Some gears are louder than others?
To fix this, what can you do? Does it take putting in all new gears? I'm working on my grandad's tractor, want to make this one PERFECT! Any help on what I need to do? Just need some guidance.
Thanks in advance to anyone willing to share!
