Could someone please advise the consequences of using straight 30 wt. non detergent oil in an old leaky hydraulic cylinder.

Is the hydraulic system for the cylinder isolated from the drive line? When I worked in a steel mill as an equipment mechanic, almost all our lift hydraulic systems were isolated from the drive line and we used 30HD motor oil in them.
If your lift system is not isolated AND you have wet clutches, etc, then you have to use what the OEM specifies or it"s equivalent.
In TO-20 and TO-30 Fergusons where you have no wet clutches, several people have used motor oils in those transhydraulic systems(again, no wet clutches) and have reported no adverse effects. The spec oil is GL-1 and it"s getting hard to find or expensive. In England apparently GL-1 is unavailable and one forum member contacted Castrol and they recommended motor oil as a substitute.

Hope this helps you.
 
Sir....... Your response is certainly a great help & is appreciated. I will try the 30 wt. in this old independant system before I try the major rebiuld.

I suspect I caused my own problems by flushing and using the new fluid in a system that always had the thicker plain ole non detergent oil in it.

Thankyou again.
 
(quoted from post at 18:06:49 11/28/09) What cylinder is that pictured, with the switch controller on top?

thanks

It's the way they did it back in the 40s/50s.... at least Brockway did.

The system works a little better with the 30 wt non-detergent in it but the hitch does drop a few inches when the upstroke is applied.

I have some 2 "0" battery cables on the way and when I get them installed I suspect I'll put the ole girl to bed for the winter.
 
Got the 00 cables today and froze my fingers replacing the #2 cables I had on there.
The result is zero difference ........ Oh well ... another $50. down the tractor drain.

Got some Seallube on the way to try on the leaky cylinder ...... that's only a $20. shot in the dark.
