830 CASE Hydraulics

Report to Moderator

I live in Canada, freezing temp.
The hydraulics on this newly acquired 1973 CASE 830 worked great before winter. Now that it has turned to winter here, the bucket - she no lift much .. I want to drain the hydraulic fluid ( that I think is old and would help if changed) BUT I don"t know where to drain it. Sounds stupid. I bought a manual off Ebay, but it was a 1965 manual and not the same for hydraulics. So until I purchase a 1973 manual, I can"t tell where the drain plug is, and how to replace fluid. I presume there is a method to replace most of the hydraulic fluid ??
Any ideas ???

First, never try to fool the facts.
Everyone that responded was 100% right.
My serial # checks out to be a 1965.
Crap - since I was a fool and bought a 1973.
(I considered that to be quite a difference.)
(1965 - 1973) ??
What I can say, is that it runs pretty good and some TLC will probably make it work for me.
When I looked for images on the internet (x#!$), I thought the front wheels apart (rather than close together)were in fact, newer.
My sincere "Sorry for the mis-lead".
The manual I bought does say 1965.
Still the same problem,and this manuals hydraulics are different. Likely past owners thought $100 for oil replacement was toooo much instead of a good investment.
I certainly appreciate the advice given, and will try to pursue.
Thanks so much for now,

last 830 was built in 1969. 1965 thru 1969 were the same. There are three drain plugs under tractor. One is above the drawbar one is just in front of front drawbar support and one was ahead of that. you should get about 15 to 17 gallons of oil out. Dipstick and fill hole is on left side of PTO housing. If your tractor is different than this then maybe you have a 1963 830. These are different. If you have more questions I will try to help. Stan

Kenny- You sure you don't have an 870. I don't think they made an 830 after 1969.

Yepper - 1973 CASE 830
I bought a manual off Ebay for a CASE 830 but it is a 1965 manual, and although many parts are much the same,the hydraulics are not.

Kenny, If you have a 1973 Case 830, you'd better lock it up, because you're the only one in the world with one. Either your looking at a serial number wrong, you have an 870, or someone is lying to you. Is the hydraulic pump on the back of the tractor by the pto, with rod operated valves exposed, running up to the control levers? If so, yours is pre 1965. If not then it is a 65-79 model.

has anybody ever taken those valves apart? my control levers sometimes stick, and I think that is another symptom of why my hydraulics seem to be getting weak. perhaps a rolled rubber o-ring?

Today's Featured Article - Massey Ferguson 35 (and up) Tractor Assembly Notes - by Jack Wetmore. These assembly notes are for Massey Ferguson tractors with a two stage clutch and 6 speed, 8 speed and mutli-power transmissions. I see a lot of discussion forum messages regarding damaged clutches from improper assembly. The objective is to have the engine and transmission slide together safely and easily until the gap between the two halves is less than 1/4", BEFORE tightening any of the bolts holding the two together. Using bolts to draw the two halves together will damage the PTO ... [Read Article]
