those Ali race jacks from blatchat

[jackal]

did anyone get one ?

mine isn't working and i coudl really use some help

It has a slotted screw on the top plate and also 2 hex head grub screws


i tightened the main screw up

the 2 hex head grub screws i opened

I pushed the piston in and some oil came out of these


but after tightening everything back up (without sucking any air back in) the jack does the same thing ... it will go up but then once it starts to support any weight you just pump it forever and it does not actually go up any further

would appreciate any pointers

Seems to be a common occurence, Blatchat thread gives seal sizes if they need replacing.

lol... typical blatchat

THOUSANDS of people descend upon the thread stating that their jack is fine ! REALLY friggin well helpful !

anyway, thanks NF, that will help me.. cheers

Mine gave up too. Be interested to know if the new seals work. Can't be bothered trawling BC to find out what the problem is, 14 pages of being told "you are bloody well lucky to have paid money for the thing in the first place people gave up their free time to do this for free doncha know" is more than I can take

its like the old R500 again

4 people's engines went bang then jecks, Carmichael and a few others pipe up and say their has been fine for the last 4 decades

so that makes... let me think... 4 bangs and about 8 no bangs

so thats a 50% failure rate

Mine fecked up . . . so have those owned by several friends. Though in fairness, other people have had no problems.
Tried fixing mine with new o-rings, but after hours of farting about, it wasn't having any of it so I chucked it.

It's still appalingly bad.


Imagine 33% of all 5 series BMWs across the world spontaneously combusting !

As funny as the entire French air force crashing into a fireworks factory

BTW my jack failed too, I replaced the hydraulics with a cheap (£13 trade price bargain) draper one, rough calculations reckon it's good for abour 400kg (lever rates all different) which is fine for race weekends.

I should really have a look at mine as i probably shouldn't of used it to pick up landrovers

Q: Do you get what you pay for....?

Just a thought.

My jack suffered seal failure early on.

Replaced seals and removed swarf from everywhere, refilled with new fluid.
Has worked fine for the last few years.

I've passed it on now, so I expect it will now go wrong!
Colin or Pete if you're reading this, I hope it works as well for you as it did for me after I rebuilt it!

Paul, are the seals square section seals, like brake piston seals, or o-ring type seals? Can you recall the sizes and the supplier you used? thks

I know you don't want to hear this... Had mine from the initial buy and it still works. It will lift the Passat estate ok too.

Fergus, I'm sorry I can't remember who I got the replacement seals from, but ISTR that Norm had arranged for some spares with the batch, and these came from them. There was a blatchat thread on the seals. The jack failed quite early in its life. The actual seals are round O rings, so it should be possible to just buy replacements once you've been round it with a caliper gauge.

great. thanks. Mine's OK at the moment, but handy to know where to get the service items from!
