Spring Compressor for W114

I'm attempting to fit springs back into my '68 250/8 (W114) and am haveing a difficult time locating a spring compressor that will work.

The JTC knock off of the Klaan spring compressor sold on ebay looks good, but before I drop $200 on it i'd like to know for sure that it will work on a W114 chassis. If someone has used one please let me know.

Also, if you have access to one and could mesure the diameter of the telescoping rod that would help me determine if it will fit. The hole in the LCA is ~3cm, which isn't very big.

Thanks,

Steve

Also,

Anyone that has installed springs into a W114/W115 or W107 - please let me know what you did to install them.

Thanks

A helpful member on another forum informed me that the telescoping rod of the Klann style spring compressor has a diameter of ~4.5cm, which unfortunately will not fit through the 3cm hole in the LCA.

Does anyone know a spring compressor that will fit?

I guess the only other option is to jack the LCA up with the floor jack, pry it into place with a crow bar, and fit the bolts.

Any other (safer) options would be very much appreciated.

I got the springs back in using an internal spring compressor I borrowed from autozone. The brand is OEM and it consists of an aluminum block with 2 hooks to go over the coil. It comes with a forked plate to go through the coils, but the MB coils were too tight to allow it to fit properly (or be removed when compressed in the car).

So I came up with this configuration - I slid the rod of the spring compressor through the hole in the LCA and threaded it into the fork block. This compressed the spring against the LCA. Note the cable as extra saftey. Dono how effective this would be, but better than nothing. The cable is stronger than chain. Since the spring is compressed to the LCA the susspenssion assemble needs to be lifted into place and the cam bolts run through the LCA bushings. Lineing up the passenger's side was easy, the drivers side was pretty hard and took some pounding and wedging to get it in there.

After everything was hooked up I removed the spring compressor rod from the bottom, folded the hooks together and looped twine around them to pull it out of the top of the spring. Pulling it out w/ twine made it much easier.



This set up wasn't ideal, but much safer than simply compressing the LCA with a floor jack. It worked pretty well and I wouldn't have a problem doing it again.

I still would be very interested to know if there is another spring compressor that can be used with the W114/W115 chassis. Some people on other forums have said to used Klann type compressors, but I can't see how it would fit. I think they may have used the compressor on a later model and just assumed it would work. Any other opinions or ideas would probably help others with future projects.

You don´t need a spring compressor in W114 and similar setups. Unbolt the control arm from the hub and lower it, take out old spring, install new spring and use a jack to lift the control arm, fasten it at you are done!
Newer merc´s with a McPhearson strut WILL NEED a spring compressor!
