Front Coil Spring Removal - TKMad - 06-29-2014
So I bought new spring pads and a coil spring compressor for my '85 W123:

And I cannot figure out how this is supposed to work. I know, small disk opening on the bottom of the spring and large opening at the top. Insert compressor, aka binding tool from hell, and turn 60 degrees to lock it in. Then turn tool and it will compress. Well it does compress, as it drives the threaded rod right into the lower control arm and binds solid.
Am I doing something wrong?!
Very frustrating!

Without pics, it can be hard to judge what you're talking about. Would compressing the spring by raising the LCA help? Like putting the tire on the ground or a jack under the LCA.
I've used my dozens of times. Great tool, but it can be fussy to set up.
Is it that time of year already? - mbz123 - 07-01-2014
Oh, I so do love to watch the annual Darwin awards!!! Never a dull moment.
JK OP. But +1 on those pics.

You have to be very careful how you place the plates, they have to be far enough apart to compress the spring enough. On mine before I cut them I had to pry (not very hard mind you) them out with a shovel. Had the same problem with the center part hitting the spring perch.

I'm thinking that a spacer on the upper disk would work, as well as cutting an inch off the threaded rod.
Basically the tool is just too long for the W123 springs.

I'd go with the spacer before permaltering a $$ tool. I'd also tether that spring to structural before going at it with a shovel!:eek: It don't have to knock ya upside da head or in the shins to be costly. Just my luck, I'd have some brand new shiny sparkly high dollar-ee doodad I foolishly set down near by and presto chango, next thing I know, I gotta front row seat to witness its destruction! Neato, oh no ):

I got that thing and it worked 4 me. telescoping part was had fit through hole in top though. i put the lower part 2 or three up from the bottom, and top as high as possible. i also had the car in the air on that corner and the upper ball joint disconnect from the hub.

Christ.....
W123 chassis needs the top hole enlarged a bit for the aftermarket spring compressors. This should be well known by now. Only the original KLANN tool fits (but has an enormous price tag). Smal price to pay for your health.
For STRONG springs, like used on - the Turbodiesel - may require to unbolt the shock absorber (AFTER the spring has been fully compressed!!) to gain more room for removal. The shock acts as rebound buffer and limits negative suspension travel.
Strong (=long) springs with 3 dot spring pads can be very troublesome. But usually undoing the shock solves that problem as you can push down the a-arm a bit.
Be carefull!

What's a spring compressor?
Do it like a man! Place a jack under the lower arm, remove the bolts and drop it down slowly.

RE: Front Coil Spring Removal - Edian727 - 09-09-2014
hahaha. that doesnt work. seriously, try it, spring is still compressed wen fully dropped.
I also forgot in my last post that i unbolted the shock on top. springs gotta compress something like 12" to get in, and thats the 240 spring.

You want to use the tool with a jack under the arm to keep it all straight iirc.
