Trolley jack repair

Hello - I know this isn't a tuning or upgrade question but I didn't know where else to post this - and anyway I'm a newbie so apologies!! Does anyone know if it is OK to refill the oil in a trolley jack with hyraulic (brake/clutch) fluid? Or is there something better? My jack has a small leak and now it won't lift as far as it should so I assume it needs a refill. Any thoughts gratefully received. Thanks. Rick

Re: Trolley jack repair

I filled mine with 10W40 engine oil.
Didn't think about it really but it hasn't crushed me yet.
I'm now curious on what it should have in it.

Re: Trolley jack repair

I would have thought a 'proper' service is in order i.e. seals replaced etc

Don't use brake fluid.

Any car parts shop will have the correct hydraulic fluid in stock, probably in a small bottle labelled "Jack Oil"

Re: Trolley jack repair

I wouldn't personally be wanting to use a trolley jack which I suspected had a 'small leak'.

Re: Trolley jack repair

I don't know about yours, but I think mine needed a top-up because I left it upside down for a few weeks.

Re: Trolley jack repair

Fair point about not trusting the jack as it leaks - I don't use it alone just to start to get some height then axle stands, etc. Will investigate the jack oil and maybe a new jack. Thanks all

Re: Trolley jack repair

What David C said. Most factors carry hydraulic jack oil. I have overhauled my Bradbury (purchased 1972 : ) a couple of times now, with new seals and 'O' rings. It's normally the cup seal on the main ram that starts to allow some 'creep'. They are rarely completely oil tight in my experience though indefinitely. Always use stands, ramps after jacking.:

Re: Trolley jack repair

we use a bradbury at work as well... best trolley of the lot....

I have a Rodcraft, which came with a set of replacement seals. much stronger than the bradbury, but 40kg heavy....

Re: Trolley jack repair

I bought my Bradbury as it was quite long, and quite wide, and low enough, to go easily between that old 'E' types twin exhausts, to locate under the rear differential unit.:

Re: Trolley jack repair

I rebuilt my 3 tonne trolley jack, after the seals gave up. I bought a box of rubber 'o' ring seals off ebay, some trolley jack oil, a couple of hours stripping and cleaning and hay presto. I always use stands now just in case, but better than taking 30kg's of metal to the tip!

Re: Trolley jack repair

Aye! Hydraulic Jack oil c/o Halfrauds at about 10 a litre.

New seals may help too.. really a jack can't easily just "collapse".. they tend to sag progressively... so should be some warning unless you really botched the rebuild.
