Just a heads up... I had one of the female hydraulic quick connectors on my BL-7000 fail past weekend. I could not disconnect the hose from the rail unit. So I unscrewed the connected pair and took to my workbench where I applied a little "persuasion" and got it to release. Now I can get it to connect and disconnect but not smoothly so needs to be replaced. Too far outside of warranty to get any consideration from QJ, even though lightly used. Oh well.

If you find yourself in this situation and go to the QuickJack parts webpage your jaw may drop as to the cost. Mine did, so I went looking. Turns out these are standard ISO flat face connectors with 1/4" NPT threads and available many places... I got the one linked below and it works great. The existing QJ male connector even fits into the new female so I have a spare. These come with nice dust caps that fully cover the sliding collar on the female piece. And the price is right.

Gosh, I was concerned from the thread title that the failure dropped your car on top of you! Glad it was a non-fatal failure.

I too sometimes have a hard time getting those connectors apart. I think there are some dimples on the connector that must line up and even when they do line up I have to fidget with them. I'm guessing that is a safety feature so the hoses do not come apart accidentally while under pressure?

raylo

Yes, you need to line up the dimple with the slot, but then releases easily. That was not my problem. Coupler is broke or jammed. No visible damage.

Poor-sha

Mine leak and in general seem to be of poor quality. Did yours and do the replacements you ordered leak?

Flame Red

No leaks here - not a drop.

raylo

No leaks with any of mine.

Don't mean to be piling on... but no leaks with mine either. I thought maybe another data point would be helpful.

Thanks to raylo for the alternative source. I bookmarked the link.

Poor-sha is yours fairly new or an older one? I'm looking at buying something I may have to pull my drivetrain.

I've had mine for a while now but have not taken it out of the boxes. Should I be looking at or replacing something when I set it up? It's a 7000.

raylo

No, you should be good to go as-is. I had no leaks from the 7000 I bought in Feb 2016 when it was a new item in the inventory. IIRC they all came with the improved connectors that don't leak. I just had one connector fail later and was easily replaced.

badhabit_wb

I was either going to by one of these or a Bendpak lift but I have 10' doors and it would waste a lot of space with the lift. Not sure if I could drop the drivetrain on the lift or the Quickjack but I think I can with the Quickjack.

The only leak I have is the air cylinder. Have to get around to fixing it.

True, these couplers are standard industrial parts. NAPA, Motion Industries, and many other parts houses have them. Unfortunately most are made in China now days, still may be able to shop around and find the good ones.

badhabit_wb

Does it lift high enough to remove the drivetrain?

BELVIN20

My 7000 series started leaking at the coupler last week when I used the jack. Mine as well is out of warranty, so I will be looking for a local supplier for replacements.

raylo

What do you mean "at the coupler"? If it is at the threaded connection check to make sure it is tight and to see if the o-ring is torn.

got2hav1

About 24" depending on the model. Going off memory here but I think that's about right.

badhabit_wb

I think it's around 20" but I'm not sure how much the drivetrain has to drop. Should be pretty close. I've never dropped one on a c7.

I keep looking at getting a QJ but these coupler problems bother me.

I just used my QJ 7000 to remove and reinstall a 4 speed transmission in my 1966 Pontiac. Room enough to even roll over on your side if you must.
Easy to adjust linkage and check clutch adjustment, it sure beat jackstands like I did before.
