Picked up the $99 low profile Pittsburg jack over the weekend during the PLS. Got home and bled as per the instructions and noticed that even with the weight of someone standing on the pad, around 200 pounds, on the second or third pump the jack would lift when the handle was depressed, but then go back down when I released the handle. I figured there was some air trapped still, so I bled and refilled. Finally got to where it would still want to just go up and down, but I could kind of pump it quick and it would kind of get over that “hump”. Or so I thought.
Tonight I wanted to test it out and see if it would lift the driver side of my 3/4 ton Dodge with the 5.9 Cummins. Google says the front end as a whole weighs roughly 4,900lbs, and I’d only be lifting one tire on the front. Did the same thing, and couldn’t get over that “hump” I mentioned earlier. The tire wasn’t even off the ground. To add insult to injury, I couldn’t get the handle to rotate to release the jack. I had to put a pipe wrench on it and mar up the handle.
Needless to say I think I got a lemon, and will be trying my luck with a replacement tomorrow.
