just a little heads up on the china jacks. i had one just like the o/p'ers its a nice light weight jack that i used for several years. then it started to leak oil then it wouldn't lift. so i took it apart to see if i could fix it. what i found was a badly rusted pited cylinder. these things do not have a seal on the shaft where it exits the cyinder. my problem was i washed my jack a few times when it got dirty and dusty. the water runs right in the cyinder through where the shaft exits and lays in there as there is no way for it to get out. soon you have a rusted pited cylinder that leaks. moral of this story don't get your jack wet![]()
Ive Never seen a Jack that didnt have a Tank Nut Seal (Normally a Recessed Oring inside the Tank Nut). Are you saying it was Metal to Metal where the Cylinder exits thru the Tank Nut?
Here is a Picture that Covers a Tank Nut Seal Location.
