Hi,
Just a quick repair to the leaking valve on my 10 ton bottle jack. It was making a mess of my garden hut floor so I finally have done something about it.
It was the thick rubber valve seal that was leaking so I turned a circlip groove into the valve shaft and then turned a suitable length brass bush this less than the outside diameter of the rubber seal; to determine the length of the brass bush I refitted the shaft and rubber seal together with new circlip tightening it then I could measure the distance between circlip and rubber seal adding about 1/16".
The brass sleeve now compresses the rubber seal enough to prevent further leakage. The shaft measured 10mm diameter and as I have a 10.1mm reamer it proved a simple job. I've enjoyed the use of this jack for well over 30 years so it deserves a bit of TLC.
Kind regards, Colin.
