I bought an autolift from America's Pride out of Mass. Most of it is made in China. Well I have had alot of issues with it. All I get is email service no ph contact but they have sent me replacement parts.
I cant get both rams to go up at the same time so the car wants to lean. I have control valves to control flow to each side but it makes a little diff. but not much.
I have bled the system till I am blue in the face and there is an equalizatin valve that is supposed to equalize the system but that doesnt seem to do anything. They sent me another equalization valave but it hasnt made any difference.
If anyone has any experience or opinions chime in. Thanks Tore

This lift doesnt have cables its a dual cylinder. There is an equalizer tube that goes up over the top and supplies hydraulic fluid to the other cylinder.
There are flow valves that control the amount fluid going to and from the cylinders. The ram farthest away from the controller is always slow going up. There is an equalizer valve and its supposed to equalize the pressure but it doesnt seem to work and they sent me another one? I am kind of lost maybe I should have them send me another valve.

Tore a stupid question but is the floor level ?. Mine is cable driven and i had to make a small adjustment. What i mean is when i lifted the lift i could hear the lock's click in but wern't together, corected that with a small adjustment to one side. With a hydrolic lift' make sure everything is plum. and make sure resivor is full should be ok. Bobby Z.

(BlasterTech 70) appearently you looked at the website. There is no Diagram the motor is 220 single phase and I have switched the wires around and it made no difference. Its a very simple setup and there are 2 flow valves that control the fluid to the rams. I have switched those around no difference. Also an pressure equalization valve which I replaced and I still think is the culprit. The lift is called AM-Pro universal lift.
I cant get ph conversation only email and they do answer and they have sent parts. 1 ram, 2 velocity fuses, 1 manifold block, 1 complete power unit and resivoir. 10 gallons of fluid.I will say they have tried to help and the guy I am dealing with has apologized for what I am going thru.

I am having dreams at night about this thing and there not erotic.
Bobby the lift is plum they sent shims and I plummed it square. The place I got this thing from is from up Mass.
Anymore ideas toss them at me.

On a single phase motor make sure you swith the internal wires not the line (feed) wires. Typically on a dual voltage motor it is 5 & 8

If it were me I would add a pressue gauge on each cylinder to help me trouble shoot the system. Help you know what your up against in pressures.

You could have a bad cylinder. If the rings are bypassing fluid in one of the cylinders then you would have a tilted lift. Does it always move slow on the same side? Use the pressure gage first to see if the cylinders are receiving equal pressure then go from there.

They sent me another cylinder and I swapped it out no difference. But the gauge is a good idea. How much pressure should I be looking at to buy thee right gauge? Tore

Are you sure it doesn't have equalizing cables? I've never heard of one that didn't. I visited their website and it appears to me they have the equalizing cables and pulleys.

No mine doesnt have cables its got a hyd equalization system which isnt functioning. Look at their site mine is the AM-Pro Universal lift.

Hmm interesting mine is a dual cyl setup as well but does have the cable to keep the arms level

it also has safety latches incase of hydrualic failure

I am guessing this is your lift



http://carliftswarehouse.com/universal-lift.shtml


is there any type of safety latches on this incase the hydrualics fail?

looks like you need to restrict the ram that is closest to the pump as the line going up and over is going to slow down the flow of the hydrualic oil
get a gate valve on the pump side ram that you can adjust the flow to it to equal out the rams


man going up and down would be tricky you get a car heavy on one side

it is going to slow the heavy side down anywhere in between all the way down or all the way up I can't see this lift really working all that well as there is nothing preventing one ram pushing fluid into the other ram when the lift is in the middle of the stroke

Thats the lift. There are 2 valves that control the flow of oil to the rams to compensate for the speed. There is a fuse at the bottom of each ram in case a line drops pressure it will keep it from looseing pressure all the way.

Like I stated the valve closest to the controller is only open 1/3 of a turn thats the min to keep the system flowing. and the the other ram is open like 3 full turns full bore. I have switched the valves around also to see if its a defective valve.
I am going to Home Depot and get some plumbing fittings and plumb in some pressure gages and see what transpires. The guy thats the service guy usually checks his emails on Sat and Sun but hasnt gotten back to me today. Hes probably as tired of the situation as I am. I cant work on the lift for a couple of days cause now I have to put a tranny in my son-laws drag car. Thats ok I have brain fry anyways.

Keep the help coming and Thank you Tore

If you look at a picture of the controller you will see a manifold block and some valving I really dont think it can push fluid from one ram to another. Tore

Your alot more tolerant and patient then I am. I belive I would either have requested them to send a rep/tech to look at it or I would send the unit back and demand a refund.

BTW- Being that they are having you work on the problem. I would ask for something in writing that they were using yourself as their tech/rep incase something happeneded in the future and something failed causing a serious damage/injury. JMO

I seen the manifold but unless it has two hoses going back to the pump
to return fluid when you lower or raise it if it don't then it has a common junction thus enabling it to transfer fluid from ram to the other allowing one side to drop while raising the other in mid stroke

when stopped it has to have a shutoff valve in between the two rams to isolate them does it have a valve to do this?

I setup my own lift in my shop and your pump looks like mine one hose from it to lift both rams thus a common junction without the cables on mine the lift arms would go up at a different rate like yours as the fluid would go to the path of least resistence the cables forcing the arms to go up at the same time

Blaster I have been patient cause I am so busy with work I dont have time to work on my stuff. But I have to give this thing straightened out.

InfoFord it doesnt have a valve as you asked. But in the manifold there is an equalization valve that is supposed to equalize the system. I just got an email from the place and he still thinks it air in the system.

How can I pressure bleed this thing I have run 10 gallons thru it.

so when you stand on the pump side arm does it still lift faster then the other side with nothing on it

hydraulics are self bleeding just going up and down works the air out of it

as long as the pump doesn't suck air when you are lifting it will work the air out

try this little test get you and a couple of buddys together

run the lift up about 2 feet then you and your buddys step up on one of the arms and see if it goes down while raising the other one

if it does then you have a common pipe between the two arms and it will never lift equal

Infoford is right. You need a hydraulic pump with two phases so that each phase powers one lifting ram. Without the equlizing cables this is the only way it can work. Don't know if they make a pump like that. You may have to rig up the equalizing cables yourself. Shouldn't be too difficult but it sucks that you have to do anything...
