Car jacking
#41 Re: Car jacking
+1 for the Thor nylon hammer. Heavy and does not mark the spinners and as said, nylon head is easily replaceable.
Some may have noted my "complaint" that the painted seam between bonnet lower edge and door front lower corner on my car has cracked. I've come to the conclusion that this is the result of my testing my BMW 3 series jack, lifting one side of the car at the jacking point

Buying one of the 944 jacks.
Is the purpose of filing the oblong lug to fit the factory jacking points?

Yes. The 'foot' of the jack is elongated and the rounded ends need to be filed down to fit the jacking 'shoe' on the car. As the Porsche jack is made of aluminium it is a simple job to do.

Very nice jack. squared it off and it fits sill jacking points perfect if I MUST use them at some time. Gonna pickup a rubber puck and drop a locating hole in it to use with the jack.
Never changed a tire on the road, always used the floor jack in garage at one point or another or it was already up on stands.
Assume best points of lift for a rear corner is at the radius arm body attachment bolt to body and for the front corner at a lower control arm knuckle?

#46 Re: Car jacking
Problem??
Tried the Porsche scissor jack (same as shown in Heuer's post) for first time at rear radius arm attachment at body to lift the rear corner and can't even get the tire fully off the ground!
Using the crank (looks to be the same one that is shown with the jacks) that came with the jack and it gets so hard to crank it won't actually lift all the weight.
Easy to work with no load, starts to lift body fine, gets progressively harder to crank and then forget about it.
Do I have a bad jack?
Is this a problem jacking point for this jack on the car?

There is a long and short version:
Short (for 911 turbo)
Long: (for 944 turbo)
911 one won't be high enough.

17” fully collapsed as shown in your picture, 15” high fully raised.
Musr apply some “weight” resistance to the jack once it is partially extended in order for it to continue to raise.

Hope these come through ok.
Perspective is a little off on the tape measure to jack, go with my stated figures.

#54 Re: Car jacking
That does not seem to make sense to me. With the jack fully collapsed (down) the lever arm for lifting weight (the car) is at its worst condition and when the jack is mostly raised the lever arm is at its best.mtnjag wrote: ↑Sat Dec 12, 2020 6:36 pm. . . . and can't even get the tire fully off the ground!

That is (illustrative only) when the jack is down, 1 turn of the crank will be lifting the weight say 1 inch but when the jack is up, 1 turn of the crank will lift the weight maybe 1 tenth of an inch. So as the weight is raised, the effort to turn the crank should decrease. If yours increases, there is something wrong with the jack.

It works as you describe as far as the distanced raised-when collapsed starts rising more distance per turn than when extended and diminishes the further up it is.

#56 Re: Car jacking
Sorry but your descriptions of the problem do not make sense to me.
If the jack will not lift the car sufficiently when fully raised to be able to remove the wheel, is one thing.
If you cannot raise the jack fully with the weight of the car on it, is another. Which is it?

Is the jack worn ie..stripped threads. Just a thought as it will work without load.

Jack looks to be in good condition.
The jack will not lift the car with the weight fully on it.
It has plenty of distance of lift available in the design of the jack to lift the car. See my pictures with dimensions.
It will begin to lift the body when the full weight of the car is NOT on the jack. As it lifts the body more and more weight of the car is on the jack it hets harder and harder to crank until it is finally impossible for me to crank it. I cannot even get close to fully raising the jack.

#59 Re: Car jacking
Hi Layne...im struggling to see how there can be a problem here its a 900kg jack....however jacking under the large radius arm mount i could see a potential problem that at the car starts to lift the mount starts to move as the radius arm starts to lower...is it pushing the jack off center and making it harder to turn......how have you located the jack onto the radius arm........how about trying the jack on a non moveing part on another car..like your daily driver....Steve

Have you tried jacking the car from the Factory specified jacking point? This jack was recommended as a replacement for the Metallifacture one and used for the same purpose. If you want to use the Porsche at other points on the car it is recommended you make or purchase a wooden, alloy or rubber pad. They cost about £10 on eBay and increase jacking height:
My 993 (which has the same jack) has a ground clearance of 110mm and weighs 1,370Kg. The E-Type has a ground clearance of 140mm and weighs 1,098Kg.
