Beginner Hydraulic oil question

[Anonymous-0]

I purchased my first 8n. I picked up 5 gals of 80-90w hyd oil at a Farm supply store. But I'm worried a)how to do it right, and b) if this is the right oil. Can someone instruct me how to change the hyd oil, and if this is the right oil? I plan on using it year - round...thanks

Erik........this has be asked an answered many times, you might want to check the "archives" at the top of this great N-Board.

Howsomevers........for you special......as a general rule, enny hydraulic oil that is multi-weight is NOT GOOD. Why? 'cuz it generally has "additives" that are un-friendly to yellow metal (brass). tip; read the LABEL; it will generally say sumptin' "good for Ford tractors". Wadda concept, reading labels.

While Ford/New Holland (now CNH) recommends hydro-tranny oil that meets their specs: M2C-134D, a 60-wt oil, the 1939 Ford hydro-tranny oil specs was 80wt mineral gear oil (iff'n you can find it) Modern GL-1, is close approximate. DO NOT USE modern multi-weight GL-4 or GL-5.

How to change hydro-tranny oil??? Start with the diffy drainplug first 'cuz it peees with some accuracy. Then drain the 3" tranny plug, then finally drain the 3" hydro plug. DO NOT DRAIN the corner hydroplug. (ain't nuttin' there). Fill'em-up by tranny shifter. Pour slow, 5-gals of hydro-tranny oil........Dell, the greezer

you'd be better off not to put but 4 1/2 gallons in. remove bottom bolt on right side of tranny housing at rear where your footboard attaches. Fill housing. When fluid runs out that hole, you've got just the right amount in. b

Don't throw that stuff away, give it to me and I will dump it in my 8N that I am refurbishing. Supposedly you cannot buy GL 5 anymore that is not cmpatable with the yellow metals.

It takes generatins for urban legends to change.

Like my pop always thought that you could never change brands of oil in a motor.

It is absolutely not an urban legend.. it is scientific fact. Take a chemistry course if you are not familiar with the process and interactions.

The fact that some gl-5 oils are now formulated to not damage yellow metals does not change history.
