[code:1:5f1ff7856f] picked up a 300u the other day and need to change the hydraulic oil its watery but my manual isn't here yet so can someone tell me how much and what flavor oil i need.
Thanks for the help[/code:1:5f1ff7856f]
 
Hytran or equivalent.NAPA/TSC/walmart etc oil is fine for
that.A 2 1/2 gallon jug will fill it with a bit left
over.You should order an owners manual. That info
(and lots more) is in it.
 

Bought my 300U last year . Hyd.oil looked great however, the internal screen was plugged and sucked together.
So my advise is use Hytran ( In that small amount of oil your not going to save much going generic) and check the internal screen in the reservoir tank. New hyd. pumps cost a lot and new ones don't fit 300u plumbing correctly so you'll need to find a good used one if its bad. So don't tempt fate.

Let me know if you think I am crazy but the hyd pump on my first 300U use to growl when I started it up in the cold to plow snow....an older gentlemen in the shop I worked suggested I use Dexron powersteering fluld in it for hyd fluid...he said it was thinner and would not hurt anything.....so I did and the growl stopped and it worked great for the next 2 years I owned it and was working great when I sold it.... Just my 2 cents
 
hytrans is red right? the stuff running out of this thing is white and brown like motor oil with water. everything worked great just didn't want the water in there and its not a lot of water looks like condensation over time.
I thank you guys for the help just trying to tie up some odds and ends nothing too deep till me books get here.
