so my NP231 developed a whine the other day.
situation:
I was on an icy road, put it in 4hi.
loud whine could be heard.
shift back into 2Hi- whine goes away.
pull case apart:
fluid has a grey tint to it
magnet has really thin shavings that just feel like grease, but are magnetic
Chain NOT stretched
rear main bearing is good
front main bearing is good
front needle bearing (rear half of case) has some in/out play, not sure if that is normal
pump screen has some small shavings in it.
other issues:
generall it will not shift from 4hi-2hi while moving or under power, I usually have to let off the gas and coast a bit.
thoughts?
