Trolley Jack - Chris M

I have a DIY Kamasa 2 ton trolley jack bought from Costco about 20 years ago. It's provided very good service, but it's starting to leak from around the piston seal. I could of course just scrap it and buy another; what appear to be identical or very similar jacks are available from ECP, Machine Mart and a host of other places for around £25 - £30. Or I could try re-sealing it. Does anyone know a source of seals?

A trolley jack in my humble is the most important tool you will ever buy.

I spent considerably more last year and replaced my old faithful British made trolley jack with a Weber EU made professional quality jack, as used by tyre bays and garages.

My old one cost well over £100 some 30 years ago and is still in service with my son who uses it rarely, the new one i managed to get for around £260...over that timespan is it worth buying cheap with the risks involved, even for the few seconds whilst you place axle stands?

What they have in common is proper infinitely controllable lowering valves, all but one (and thats £150) of the budget jacks do not have such good control as well as other build quality issues, they are all Chinese made in the budget ranges.

I take your point GB, but for the half a dozen times a year I use the jack, I can't justify anywhere near £260. In 30 years time I'll be lucky to still be driving let alone doing any DIY car repairs. I never trust a jack and get the axle stand under straight away with just my arm under the car.

The other thing with a small jack is that it doesn't take up any room in the garage - I need to leave room for a freezer, tumble dryer, overspill from kitchen cupboards, bike, workbench and oh, just remembered, a car!

Fair enough Chris, in that case i understand Costco are or were selling aluminium chassised jacks for a fair price, somewhat lighter than the cast iron jobbies making then ideal for shelf storage despite being a decent mid size.

I did see identical ones at other sites during the extensive search before spending some more of my kids inheritance..;)

Wait for LIDL or ALDI to sell their (German made) jacks, both chains sell 'em two or three times a year - a decent DIY jack for £20-£30. My thirty year old British budget jack bought from a motorfactors way back when is still going strong - I've never even topped the oil up. Still lifts my whacking great Range Rover no bother!

It depends where you are and if you have any industry in your area.

I guess I have about 10 "hydraulic engineers" in a 12 mile radius and have had both seals supplied and tubes re-manufactured for jacks. I find that seals generally fail due to corrosion of the tube or rod, possibly due to lack of use and/or non-replacement of fluid.

It must be worth taking the old seal to a an engineers and asking very nicely if they could check their catalogs to try to match a seal. I find them very helpful round here. (have the other bits in your car in case more accurate measurment is needed.

This may sound like a silly question but where underneath the car do you place a trolly jack? I am always worried that I may be lifting the car that might buckle.

Thanks martint123. I'll have a google on 'hydraulic engineers' and see what comes up.

wmo - I usually place a length of wood about 2" x 1.5" x 12" under the inner edge of the sill around the jacking points. Never had a problem with this causing damage. If placed just right, it also gives you somewhere to stick the axle stand.

There's usually a solid subframe aft of the engine block for lifting the front end. Back ends can be less substantial. I use a scissor jack at the reinforced point provided on the sill, padded with a rubber exhaust hanger.

Driver's manual usually tells you where.

Driver's manual usually tells you where.

Not in my experience - they identify the location for the supplied jack fits, but its unique shaping usually precludes the use of a trolley jack particularly with modern cars where it's so easy to damage the sill trim overpanel.

Some owners manuals identify positioning for a 4-arm workshop lift but it may well not be suitable to use the same points for a single lift.

I try to use the lower suspension arm close by the tyre, then all the stresses are kept in the same place, more or less.
