Hydraulic Jack - 23/01/19 05:30 PM

2015 Plus 4...

Being a but lazy and not going out to in the cold to measure but I am looking at a new jack (10% off at screw fix at the moment). They have several "low profile" ones which go from about 90 mm and lift to 360 mm. I would always use wood block to save my nice shiny underside and of course axle stand to save me!

Is 90 mm low enough to have room to get decent sized piece of wood in under jacking points?

Their alloy race jacks fit nicely under a Morgan...well recommended.

I’m sure it is

Mine isn’t a low profile one and is higher than that and I can get a block under when jacking up front and back

“Normal” profile hydraulic jacks are ok, until you need to jack the car up as a result of a picture. That is when you will need the low profile racing jacks.
Rather than wood to protect the underbody I use ice hockey pucks.

Yes you'll be fine there is plenty of room for a wooden spreader block in there.

Front of car should be ok.
For the rear see DaveW posts re a jacking beam if you want both wheels up together or better access to creep under after putting axle stands in place.
I use a beam as the axle is quite a way forward for the jack to reach.

I have the Halfords low profile jack, it works well with thick blocks

I'm sure you know that you should be very careful using a trolley jack on carpet!
The trolley should be free to move so that as the point of lift moves backwards (as the arm swings up) the trolley tends to want to move forward to stay directly under the weight. If the car cannot move and the jack is snagged on the carpet it could be dangerous!
Bottle jacks and scissor jacks just raise directly upwards, a trolley jack swings backwards on its arm as it is raised.

The trolley jack does move slightly when the car is being raised on the carpet, the arm swings as you say, and the block remains central (Block routered into the jacks lifting point)

The handbrake is off so the car also moves slightly as it’s being raised. Once it’s fully raised then the chocks go behind the rear wheels inc axel stands in place.

One consideration when buying a hydraulic jack is the availability of service parts/service kits for them.

For example, I've just repaired my 20 year old Sealey Yankee trolley jack using an off the shelf repair kit.

My neighbour has a defective three year old jack from Halfords. No repair kit available and seals of such odd ball sizes, I can't find them anywhere!!

Some of these wood adaptors are impressive bits of kit. Personally, I have always used a large standard jack on my various Morgans over the years. No problem. It does have a built in rubber pad and operates well, with no slippage.

Bought Hilka racing low profile jack. Now sorting some timber to protect her underside. Thanks for useful info.
