I know this is an old thread but I was hoping a Weaver owner could give some info on the steps to remove and install a two post weaver lift. I am set to purchase a Weaver 2 post lift(7,000 lb) this week but have not yet laid eyes on it.
Thanks, Clint.

the bst piece of advice? plenty of strong bodies and/or a tractor to help lift and lower the columns.... 4 of us dang near got crushed laying my columns down onto my trailer, we had 1 guy push it over while 3 of us tried to "steady" the column as it laid down for that quick second it took for the "pusher" to grab hold... we used a 27' semi truck tie down strap wrapped around the top
I was the "anchor" at the end of the strap and my feet were sliding out from under me as the post fell...
my plan was to use a come a long to set them up, anchored to a pipe laying across several ceiling joists (my garage is all stick built and 16" OC) but my son cam up with a plan that worked better.... he borrowed a tractor with a bucket, we took the bucket off and used the lift arms that way...
once standing, we were able to slide the columns "just" where they needed to go. just go S-L-O-W doing this...
I traced the foot of the column onto 2 pieces of scrap paneling I had around cut them out, and used those to measure and center my lift within my door opening, I measured and set the pieces of paneling according to the Install manual and put short pcs of masking tape around those for layout, and then walked the columns inch by inch to where they need to go, then drilled for the Red Heads (concrete anchors) with the columns themselves in place.
I forget what exactly, but the is not much difference between the 7K capacity and 9K capacity versions; I know that the "feet" that make contact with the car are different, one has "screw" feet and the other has flip up feet.
there is a difference in the way the sprocket at the top of the columns is designed, the biggest difference even with the 5K version is that this one only has 1 lift cyl while the 7K/9k have 2 of them (and they are the SAME between the 7K and 9K versions) if you find a parts breakdown (go online to SVI Inc, they have them online there) it's readily apparent the differences between them.
just check your chains and rollers NOW before you put it up, while it is down.to do any maintenance on it while you are taking down and putting it up, not after it's up. I have put some of the things to check and do to this lift earlier in this thread. Rebuild the cylinders now, (piece o'cake)
There aint much that can go wrong with the arms, columns and carriages. and the motor/hydro unit can be had if needed, (does not have to be "the" exact same as original, they are always listed on Ebay) the roller bearings can be had via Ebay or a bearing house, as can the chain, these lifts were meant to last several lifetimes.
The thickness of the columns, the sheer size (sq ft) of the column feet, you do not see, in newer lifts.
