I have an old looking trolley jack, which is almost certainly a Sealey item. I've spoken to them regarding Identifying it but all they could come up with is it is probably is a Sealey and a 3t version.
Anyway recently I bought a mk.4 Golf TDI 130 for my Wife and during the obligatory inspection/oil change/replacement of all filters I tried to lift the front of the car to get the damn undertray off. However just as the front wheel started to leave the ground the jack started making what I can only describe as a faint hissing sound with each pump but failed to lift any higher.
I've since tried it on my Land Rover and it lifts fine, I've topped the jack up and bled it but it still wont lift the Golf!
The only difference is that on the Golf the jack is under load from about 5-6" from the floor whereas with the Land Rover it is around 10-12"
When I put a wooden block under the Land Rover axle so the jack is under load from roughly the same height as the Golf, the jack again fails to lift after the first inch or so.
One thing I have noticed is that it appears someone has tampared with what I believe is the relief valve as the slot is damaged (see attached photo).
Are the relief valves adjustable? I'm thinking someone has perhaps had a tinker with it, lowering it's capacity. It would explain why I got it so cheap!
Any advice, suggestions very much appreciated!
