How to Fill, Bleed, and Replace O-Rings on a Trolley Jack

My Pittsburgh trolley jack ran out of oil after several years and barely worked (no lifting when pumping). Here is how to fill the reservoir with jack oil, bleed the reservoir, and replace the main piston O-ring. Once complete, the jack worked as if new.

Most concise and to the point video I've seen on this. Nicely done. Ps - that's an adjustable wrench, not a pair of channel locks.

Thanks for watching and glad it helped!

as long as i have been working on automotive repairs, i have never thought about this untill now. my wife recently started driving my dad's 2006 ranger, and during our overall assement of "things to fix" we discovered the floor jack he keeps in the bed does not go past half way. ok, needs oil; BUT it is leaking fluid past the piston. followed your instructions to remove side plate, and realized this; the cast "tower" that the device locates on for the pump handle is NOT CENTERED ON THE MAIN PISTON BODY. my piston body is offset to the left, yours is to the right. if you put the side plate back on, you can easily insert the pins from the side that has the greater offset "more space". that puts the retaining pin end on the side that has the assist spring to pull the jack down when you release pressure, but there is enough room that it does not touch. that way, if this happens again, you don't have to remove the side panel again since the pins now have clearance to be removed. great video, i learned something today. ADDED BONUS my 14 year old son helped me get the 18mm nuts loose (needed help, recovering fron knee surgery) and he laughed; "dad why did they do it the hard way, there was room from the other side". exactly, son. thanks again, robert and son

[@OliverPorter92]

Very interesting! Hope that the recovery is smooth!

[@shriramvenu]

thanks so much! I was having a problem with a leaky jack. Now at least i know its possible to repair. will give it a try!

[@OliverPorter92]

Thanks for watching! Glad it helped!

[@arontesfay2520]

I would also replace the O-ring in the release valve. It started leaking first on my trolley jack.

[@jeffj9764]

What size is the o ring in the release valve

[@donyvette3496]

Great vid! To the point and helpful. Going to try this on my old trolley jack w similar problem.

Thanks for watching glad it helped !

[@frankrobinson5453]

Great video!! Although it did drive me nuts when you called the cresent wrench a channel lock. My problem was slightly different in that it would not jack up, but also was not leaking any fluids. Your comment about jacking the pump 20 times with the valve open fixed my problem. Now my jack lifts again. Thank you so much for the great vid.

[@OliverPorter92]

Thanks for watching and the feedback - apologies on any confusion but sounds like bleeding helped!!

[@lcervantes8505]

Super. The mfg couldn't help but you sure did!

[@OliverPorter92]

Glad this helped! Thanks for watching

[@swensonj69]

For others (like myself) that were confused about the O-Ring. He uses the P8 Metric O-ring in the video. Not the A008 SAE O-ring. Also, if you have a Harbor Freight nearby pick it up there and save yourself a bunch of money.

[@Hwolf777]

Hell yea

[@johnnybrowning470]

What you're calling channel locks, we commonly refer to that as an adjustable wrench

[@OliverPorter92]

Yes I misspoke.

[@bobomomo3764]

That's a perfect tutorial thank man P8 is solved ✅ Do u know the other O-rings sizes for this jack? ☺️💛

[@OliverPorter92]

Thanks for watching and glad it helped! Unfortunately I do not, but Pittsburgh releases a parts catalog on the harbor freight website. Hope that helps.

[@28illustrator]

having trouble with brand new jack. The release valve wont turn left or right so the jack wont raise. any ideas?

[@thedude4795]

i was looking at ordering an o-ring replacement kit for my jack, but price + shipping wouldve cost me One Hundred Smackaroo's ($100) needless to say I'm just buying a assortment of o-rings like you have in this vid.

[@treborterb]

I think that the tool you are calling a channel lock is really a crescent wrench???

[@Hwolf777]

The correct o ring size is 7/16” o.d. X 1/4” I.d.

[@OliverPorter92]

Thanks! Will fix comments

[@Hwolf777]

@@OliverPorter92No. Thank you for uploading.

[@peterdunn5535]

Head light restore

[@Hwolf777]

The P8 o ring in the same set you have. I bought from Harbor Freight. Doesn’t fit the shaft correctly. There is a gap when the new o ring is installed. Where there wasn’t a gap originally.????

[@Hwolf777]

Good video though. Thank you for uploading it.

[@OliverPorter92]

Thanks for watching. I had no gap but could have been lucky.

[@phillipmota5945]

This particular jack stops lifting after a few uses. Especially the newer ones.

[@jessvlogonce8674]

It didnt show how you fit in the O ring to the tube..i think you get also hard times like me...

[@311superfly]

until you apply RESISTANCE above gravity you have just gone through the motions and NOT shown us better working. good editing though.
