Harbor Freight 3 Ton Low Profile Floor Jack Maintenance! 

Thank you so much for uploading this. I inherited this exact jack from my older brother who passed away unexpectedly in 2020. I have other jacks as well, but being that it belonged to him, I'd like to keep it going as long as possible.

Thanks for the video it was very informative. Just for future reference there is a large set bolt that unscrews at the back of the jack located at the base of the handle that, once loosened, removes the entire handle. I only know this because I couldn’t figure out how to remove the entire handle for the longest time. Thanks again.

Never do both sides at the same time, just in case you need to reference, and I need to reference. Super solid and not so obvious advice.

Should've reminded people about the teeny tiny gasket on the drain plug. Sometimes it doesn't come out so you've got to delicately pick it from around the drain hole *before* draining.

Great information

does anyone know what the set screw "turns" are? Yeah, i took it apart without knowing to count them? thanx

I have discovered a rule about removing circlips: They will always fly off and land in the most inaccessible part of one's garage.

My jack makes a loud squeak when it’s under load and lifting the car. I replaced the fluid and removed and cleaned the pistons.

Nice work on the maitinence

I have a dayatona floor jack harborfreight upon greasing the bearrings their was 2 ball bearings missing when disassembling it i noticed.

Needed to put the wheel in a vice it makes it SAFER and easier taking the retainer off. I know i gouged the shit out of my knuckle when my screwdriver slipped. Yes i did use my vice to finish both wheels. Pluse i drilled and tapped them for zert fittings. Slowly turn the wheel while pumping the grease it fills up evenly with clean grease whipe off the dirty excess grease and you are done. My solid axel i drilled tapped and put a grease zert. A couple pumps of grease and wipe off the dirty excess grease and your done. Have done this to all my floor jacks. Difference between your jack and mine was mine said to put the plug back in before jacking. Jack 10 times and slowly loosen to bleed off any air and repeat. After second time check oil level if ok put plug back in and your done. Or you can check as many times as you feel you the need to.

I have the same jack. My 2 spring pumps don't seem to want to come back out. Any idea how to fix that? Was working fine until I picked it up from my aunt in law, I released the pump so the handle would stay down while in the bed of my truck and now it doesn't to come back out like it's supposed to.

What would make the jack very slow to come down?

you are fire

Thats what she said when you miss Lmfao

On my jack I have two pump springs but only one is working can you please help 🙏🏾 nosale

Mine has a rubber plug in the fill hole and is damaged and leaks. Any idea where I can get a replacement

I used mine for 2 years and the seals started leaking out all of the fluid!

That ring needs a flat beak snap ring plier totally different type of snap ring pliers

I would of put the grease on the ball bearings then put the top on but thats me

I have this same jack but its the 4 ton model same color

I did the worst thing anyone can do.... I left my jack outside for a whole year 🤦‍♂️. Idk if it's worth buying replacement parts or buying a new one

Why would someone replace the hydraulic oil on a 6- 7 years old Jack, just inspect it fill as needed and purge it.

I should have done that to my front wheels when I got it....they are rusted on

Didn't do any of the seals.
