Ours could do with a bit of a freshen-up, as one doesn't lift as far as it should and the other doesn't lower in a controlled manner...

I was wondering if Thunder Road get theirs repaired/serviced?

It is cheaper to replace and scrap, especially for a business and H&S and insurance, unless all it needs is more oil.

Ok thanks. I just thought it might be quite commonplace to replace seals, which I would imagine is what often needs doing

Rob you are obviously thinking of the 'old days' when things could be fixed and lasted ages

We are having to replace a 2 Post Ramp at work because a 3 phase switch is intermittent and is about 1/3rd the cost of a complete new Ramp!!!

Throw away world.... sadly.....

if the jack is of a type (made in india mexico china) marketed by

silverline draper machine mart Clarke et al

finding the machine mart name or Clarke tools number for it and ordering kt from the Clarke spares department is the way i would go

did similar for my compressor and my pillar drill

the other option is to take it to bits and go to somewhere like simply bearings or orbital fasteners with the seals and asking for some new ones

Ive just bought this jack as this thread and my dodgy current jack prompted me to. Fantastic value, appears to be really good quality for the money and came less than 24hrs after I ordered it.

Looks good Steve, might get me one of those.
Does it lower smoothly?

It does Stu, so far Im really impressed for the money. My old one was a nightmare to lower. As soon as I turned the handle it would just drop like a stone. It also very slowly dropped when the car was up so I had to be quick getting the stands under it. This one is very smooth and precise. Ive obviously only had it a couple of days but so far so good. It is very heavy so more of a garage jack than one you can just take in and out of the car

I like SGS stuff. Good value for money.

Its the first time Ive had anything from them but impressed so far. Will have a look at what else they have online

I own three trolley jacks. An old 2 ton Epco which I've had since the 70,s and two modern Chinese 3 ton jacks. One of the Chinese jacks is identical to the one Steve bought but is badged as a Rocwood, the other is an SGS but a different model to the jack Steve has.
I decided to calculate the safe load for each jack based on a working oil pressure of 10,000psi which is widely believed to be the maximum safe pressure for the type of seals used. It's pretty simple maths, all you need is the main ram diameter and the lever ratio.
The Epco 2.07 tons, the Rocwood 1.5 tons and the SGS just 1.3 tons!
I wouldn't trust the tonage on the label of these Chinese Jacks.
The name on these Chinese jacks means nothing, theres only a few different models but all badged under different names.

If I had to keep just one jack it would hands down be the Epco, I can lower a car so slowly you can't see the car move.

Excellent Post, Mick!

I can only speak as I find, but the SGS stuff I have had is very good value for money and so far nothing has looked anything like letting me down. I wouldn’t lie under a car on just the jack anyway, mind. Straight onto axle stands.

I doubt anyone's about to rebuild their jack, after what's previoussly been posted but... I just found this in an oldish (2023) Practical Classics that was heading for the recycling...

Dunno why those scans are so fuzzy - they look fine on the original jpeg
