Maxjax not so smooth

[whejdak]

I've got three questions to throw out there.

1) I would like to move one post further away than what it is at now. I may have screwed up the installation of the anchor bolts on this post. Any ideas on how far away the new set of five holes should be? I've got it drilled at 120" and I'm thinking about 5" further out.

2) Instruction say use WD-40 to lubricate the post slides. I would think that a grease would be much better. Any thoughts on this?

3) I'm working with company on a problem of lift. I've got everything installed but one post lifts higher than the other by almost 2" at the top. So much so that when I raise the car all the way up, one post max's out but the other is short of where it is suppose to be and I can't get the safety bar in. If I continue operating the pump the low side comes up and I can insert the safety bar, but I'm wondering about the pressure on that other side that has max out. I've tried bleeding several times no help. When I switch hoses the problem just switches sides. I've removed the quick disconnects and connected direct to the splitter unit. Thinking that maybe it was a quick disconnect problem. NO help there either.

Thanks

Hello Bill,

Thank You for purchasing the MaxJax lift by Dannmar..

1. You want to be 6" from the existing hole for full strength..

2. You are correct, please use ball bearing grease or white lithium grease for best results.

3. Please contact me regarding this issue so I can further support you, the Max Cylinder stroke is 42" so there is no way for it to crash and create pressure when maxed out at full height. We have recently learned that removing the quick disconnects on the Flow Divider will allow the system to operate a lot smoother and keep the 1.5" side to side tolerance..

Please call me @ 877-432-6627 X126

Thanks as Always,
Gabe

yeah....grease smoothed mine right out. I tried oil and it actually made it worse. So I cleaned the oil out and used grease and it now runs perfectly. Probably raised and lowered 50-60 times over the last 3 months without a hitch.

You put the grease on the actual rectangular blocks or the insides of the posts? How much? I have a whole tub of synthetic grease, would this be fine to use?

I have both:

Put the grease on the inside of the posts. I used a spray-on white lithium grease. As the hoist rises and falls, the blocks will spread the grease out.

I had the same problem with my MaxJax; one cylinder starts raising first, and the other only starts going up after the first side is about 6" high. When lowering the lift, the "fast" side also lowers to the floor faster. It does the same thing with a car on it and it is kind of unsettling to see the car begin rising up at an angle.

I was at least able to solve the problem of uneven heights at max lift height by doing the following: 1) raise the empty lift to full height, 2) lower lift arms until the "fast" side reaches the floor, then 3) unplug the hose from that side and continuing to lower the "slow" side until it reaches the floor, 4) plug the hose back in the "fast" side and bleed (again). If I do all that, the two sides still start unevenly but they are dead even by the time they reach the first set of safety bar holes.

I have to do that EVERY TIME I reinstall the hoses and use the lift. Gabe was very helpful and arranged for me to get a replacement flow divider, but unfortunately, it didn't solve the problem. They tested my original divider and it was okay.

I've tried everything. I don't have quick-connects on the flow divider, and I swapped hoses and even swapped the quick-connects on both the cylinders and hoses, with no improvement. After further discussion with Dannmar, their conclusion was that it's most likely a problem with the cylinder, possibly some obstruction in the plate inside where the hydraulic fluid flows through. However, at that point, Dannmar was unwilling to do anything else and I understand that, given the effort and cost that would be involved in replacing a cylinder.

The lift works perfectly otherwise, and my old back is very grateful. Having to go through the unplug-lower-reconnect-bleed procedure every time I setup, is a major pain in the a$$, and I shouldn't have to do all that but I can live with it. Maybe someday when I'm feeling adventurous, I'll pull that slow cylinder, disassemble it and see what's up.

I hope you have better luck than I did in getting this solved.

X2, spray on white lithium grease.

How old was the lift when this started? Is it in warranty?

It's been that way from day 1. Lift was purchased and professionally installed about 2 months ago. Garage Equipment Supply arranged the installer.

Like I said, Dannmar/GEC was very helpful up to the point where it seemed to be a cylinder issue, at which point I was advised that I could disassemble the cylinder myself if I wanted to. The lift works acceptably if I go through the equalizing process I described earlier so I just decided to live with it.

Can't imagine it's a lubrication problem, I lubed the columns with WD40 but I'll try some lithium grease anyway.

 

[dclassical]

But if it is under warranty, shouldn't they make it work the way it is supposed to? I tend to think they should replace the defective part. This is what warranty is about.

I was thinking about buying one of these or the crome C-7000. If they dont want to fix it under warranty somthing is wrong.

Please call me so we can figure out what the problem is.. Sorry I cant recall what the original issue was. If it was not the Flow Divider the next thing to check is the Cylinder and Quick Disconnect fittings. If the fittings do not seat correctly it can cause uneven lifting as well. Worst case scenario we can put a flow control on the faster side and even it out. Hope this helps..

Gabe,

This may not be the case here but my MJ is slightly off (maybe an inch) and after careful examination I'm sure it's actually due to the floor being higher at the area of the right post and that gives the impression of unequal lifting.

Just a thought and something to keep in mind.

 

[UPSHIFT]

I was thinking about buying one of these or the crome C-7000. If they dont want to fix it under warranty somthing is wrong.

Be careful on the C7000 by chrome, it is difficult to manage 40" of lifting height with a flow divider and keep a level load, I could not imagine 74" lifting height. Also you would need 10-11' ceiling height. I also dropped by the Manufactures website and they do not show this lift ? I then searched Google images and got 2 results for the C7000 telling me it is a private label deal and support could be tough to come by. Google MaxJax images and you get endless customer and reseller images. Our customer service regarding MaxJax issues is readily available just by researching on this site alone. My 2 cents

Thanks Regguy... Ill fix him up! Im eager to fix these badboys and have learned some new things in this past year. If the car is leaning forward or backward it can cause the carriage moving up and down in the post to bind and slow on one side. White Lithium Grease or Silicon can help this but "even" loading is the best solution. Hang in there Gents and call me.. If I did not take care of it the first round give us another shot and we will make it better regardless of purchase date.

Have to give Gabe a shout out, I had an uneven lifting problem, over 3" at 3/4 lift.
After several emails of troubleshooting, he sent out a flow control to put in the line of the quicker cylinder.

That took care of my problem. After some initial adjustments on the flow control, my MaxJax now lifts within 3/4 to 1" of difference between the columns.

 

[DonnyT]

I have my lift for 3 months now and I do not have this problem at all. Did you guys experience this from the get go???

 

[Jvvmusme]

I ve had my mj for 18 months. 100% satisfied.

If your asking about the uneven lifting, yes, mine was acting up from the start.
Thanks to Gabe, I've got it figured out now.

Yes, OK thanks.

 

[omowright]

Are there any improvements on these maxjax's or have better "portables" evolved? I should like to use for lifting the car (afraid or uneven lifting) and for using one post as support jack (for larger "clear under" work-space). Won't be happy about bleeding each time the lift is re-installed ...

Check out the updated MaxJax by Dannmar. It's the all new ALI certified MX-6. www.maxjaxusa.com

Wish you guys had an trade-in / upgrade program; the MX-6 has a much better safety lock system.

 

[Teng3]

I spoke with a Mr. Matthew Quinn today via chat on the Dannmar site. He was very helpful in answering my inquiries, but in regards to what had changed between the MaxJax and MX-6, it was literally just the auto locking mechs and the ALI certification. No change to the hydraulics or pump mech when I specifically raised concerns over the numerous posts regarding uneven lifting speeds. No changes to the diverter mech either. Thus, i'm not quite sure if the MX-6 is still prone to uneven lifting or not. I suspect it might still happen with this newer model.

Additionally, the introductory posting for the MX-6 on Facebook, Oct 17, 2016 had a comment by MaxJax stating that another redesign was happening for 2017 model. Did this ever come to fruition?
