3320 50 hour complete fluid change. Bunch of questions.

That thrust bolt was loose on my 4720 also. Did you torque it to 25 foot pounds? Or maybe it was inch pounds. I'm getting forgetful.

I torqued it down to 24 foot pounds. I was rather surprised how loose it was i think it took 4 or more full turns before i needed a wrench. The book said to check that bolt every 600 hours. doubt i would have had a bolt at 600 hours if it was that bad at 150.

My 3520 was very loose too when I got it at 180 hours! I've put that many on myself since then and the jam nut is still tight but I'll check the torque again when I drain the front axle and change fluid at 400 hrs and see what the oil looks like.
Apparently that isn't on the dealer's check list or it's just too much effort the jack it up.

They start making a "clunk" when changing directions when they get too loose.
