floor jack maintenance

[///M42 sport]

I've noticed my jack doesnt lift all the way through the full range of the handle. Think the seals are wearing out, or is it from losing oil?

This topic is relevant to my interests. I have a jack that could use some servicing.

some jacks are servicable, some are toss away

just remeber to keep the pistoin clean at all times, any grit ro rust will eat up seals

I have a US general aluminum. Just curious. I don't want to open it up only to find out I cant put it together if its pressurized.

I threaten Harbor Freight employees to get a new one regularly.

That is my maintenance program.

Both. You need more oil, probably as a result of your seals leaking. Either that, or you turned it upside down or something and didn't use it long enough for the oil to resettle.

When they dont jack up all the way, usually that means a seal is bad and it needs jack oil.

anyone replace their seals?
