I just sprung a large leak of hydrualic fluid coming from the packing end of my right loader ram. THis is a model 9 "tube" loader mounted on a 1955 WD45 tractor. Is there anybody out there that can help on what to do to repair this leak...I need to get back to work.
Thanks a million for any info...
Dave

There are bolts that hold the packing in place. Try tightening them down.

Baum Hydraulics may have the seal. www.baumhydraulics.com. down load the tractor seals section and search it.

Thanks for the replies!! Much appreciated,
Before I read your replies, I ventured out on my own to solve the problem and discovered the bolts on the packing retaining collar were loose. After tightening, the leak was markedly reduced and I finished my work for the day. Looks like I'll be replacing the seals...
THanks a million!!

I sprung a leak again after lifting a 1000 # diesel engine...tightened the packing bolts a bit more and that fixed it. Thanks!!

There is no "seal" in there. It is a chevron packing and can be purchased at most any hydraulic supply house given the rod diameter, gland inside diameter and packing height. Costs about $10-$12 for one cylinder.

If your rods are scratched up or galled, you'll play heck keeping the leaks down. Rust pits are heck on the packing also. This kind of packing needs a little bit of "weep" of fluid to keep them lubricated so over tightening can cause problems also.

Yes, I will take that seriously!! I recall learning of this danger when I was in the Air Force and we had to use high pressure hydraulics to jack-up very large aircraft.
Additionally, I learned by experience to never put my finger in front of a car wash spray nozzle at a mere 100 PSI...It sliced my finger like a razor...and then a bad infection made it much worse.
Thanks for the safety briefing!!
