2 post lift column plumbing

[CJseven]

Just how close do the columns need to be front to back? Not a good pic but the bubble is touching the line on one side.

Can't get much closer than that!

Do you have a car on it?

Well, you are already pretty close already. Do you have some shims? No reason not to go for perfect.

not sure on lifts, but hanging doors, that's a mile off . personally, I would want to shim the anchor plate & get it closer

 

[CJseven]

No I haven’t hooked the power pack up yet, I have some 1/16 shims under the high side it seemed to need them before I started to tighten down the anchors. I’ll go back out in a bit and remove them and see what that does.

If that’s a two foot level it needs to be shimmed. You will be below this thing. Make it perfect

It’s a four foot level.

Use a plumb bob from the top.

I moved shims around and have it much closer , I only had a few 1/16th shims that were under it when I removed the lift from the old shop. I’ll have to get make some temporary shims today and see how that goes. Once I figure the shim thickness I’ll make permanent ones out of aluminum plate I have.

Tried the plumb bob off the top of the column the front to back is off 7/16 from the top to the bottom of the 14’ column. So I’ll have to make more shims befor3 I can go any farther.

what i did on mine was shim it perfect then tilted the post back and slap some non shrink grout under it, then bolted it down. the excess grout would squeeze out and i have full bearing once it set up, but it still setting on the shims.

 

[CJseven]

I may very well do the grout also once I have the shims in place. Something like this work ok?

 

[CJseven]

Made shims yesterday out of a few different thickness of aluminum plate and was able to get the columns pretty much dead on. Didn’t take much at all most were only 1/16 off. All that’s left is hook up power and bleed the hydraulics and adjust the cables.

 

[brownbagg]

on the grout, i just got what the box store had on the shelf, its all just basically the same

 

[CJseven]

Ok I will go by and see what they have in stock. Maybe they will have a smaller size than a 50 pound bag.

Are you all just using flat stock to make your shims?

I saw someone mentioned aluminum above but it seems like steel would be preferred. Am I overlooking something?

Happen to have any photos of your shims you can post?

Mine had galvanized washers. Nothing fancy required

I just took some 6061 aluminum plate of different thicknesses and cut some 3” squares, drilled 3/4 holes in the center then used a band saw to notch one side so I could slide it around the anchor bolt. The factory kits all use plastic shims.

 

[iowa4x4dieselman]

I would use a shim kit designed for bolts. I would bet this would be safer and easier to get perfect than grout.
