So I had my 830's rear end/trans/clutch rebuilt.. (used case hydra-trans fluid) Now I am hearing a little more of a whining noise coming from the rear then before. Does my 830 comfort king have a "david brown" transmision that I have read about that has the straight cut gears? I didnt really notice the whine before the rebuild but maybe its how is was suppose to be...just need some cheese... Thanks

What did the old fluid look like? Was it super thick and white like there was alot of condensation in it from over the years? In my experience if you change that old stuff and now have good fluid in it it may be louder now for a few reasons. 1. gears may be pitted slightly.
2. That old nasty stuff is sometimes like a thick grease that really quiets the gears even though its not the best on them.

oh yea it had a lot of water in it and thick.. that was the reason it needed rebuilt.. we had to put a couple of new gears and also a couple of new bearings in it.. that's sort of what I was thinkning.. it was thicker before and now with new grease in it, it is how it is suppose to be..

the 830 is CASE only !,..not a teneco shotgun wedding db leftover....You seem to be confused.. lol . perhaps the whine is caused by the thin hy tran in the rearend? whoops, you put hi tran in the rearend,?? ...IMHO .. 830 rearends should have at the very least 80 w oil,, and nuthin wrong with 140 in there.. I bet that is the problem ,,, Guys Chime in...

Wasnt sure how thick of fluid I could go as I still want my hydraulics to work well. I may add some 80 or 90w in with the hy-tran.. but my book calls for hy-tran..

Kevin the gears you had replaced, did they replace both gears that run together on just one as doing this can cause a gear whine due to one new and one used running together just a thought, also is it a "CK" (regular 3-pt) or a eagle hitch model as the early one does call for "90wt" but the later used TCH which I replaced with Hy-Tran some 20 years ago in all of my "CK's" with no problems or extra whine cnt

its a CK, sorry, though I stated that but guess I didnt...not sure what all gears were replaced but it sure could be that one old is running against a new one.. that could sure be it.

you guys might want to check your facts,from the operators manual for ser. numbers 8173401 and after which would be a 1961 the 30 series had a common sump and the eh models call for 18 gals. of type A or Case hi lo-TCH which is usually substitited for Hy-Tran though TCH is still available, JD 303, Cenex Quick lift or equivelant universal trans. draulic oil will also suffice. I don't rember if our 1960 830 had common oil or not.

if it's whining theres two gears that are not happy together and oil isn't going to fix that, if it's noisy it's scuffing metal, I would never reccomend mixing gear oil into hytran, if it will lube a 300hp Magnum I think it will protect a 65hp tractor ok, and if the hydraulic pump is worn fix that problem

How bad is the whine and is it all gears or one in particular? A soft whine in the higher gears is probably ok if the ring and pinion are set up to spec. My 61 830 is quite noisy like an loose bearing noise and has run many years with out causeing me any grief. Those trannys are tough. I would suspect the lighter oil is contributing to the loudness but I agree that no thicker oil be mixed in , If you are sure the settings are right and all the gears are in good condition run it in my opinion. mEl

My 730 Comfy has always has a slight "whine" in the high gears. Never had any problem though.
