I've used a normal spring compressor successfully. But it did take a bit of arranging for it to clear, as it was a sort of tight fit. That was fronts only, as I've got a 712.

I have had moderate success with a spring compressor. I "removed" the spring as a side effect of pulling the axle, so I dindn't need a compressor for that. When I used a cheap compressor to reinstall the spring, it broke under a lot of tension, sending both ends rocketing across the shed.

I had my best luck when I used my hydraulic press to compress the spring, then the compressor to hold it compressed while I installed it. The setup made me very nervous. Plus the upper part of the spring compressor fouled the body and made it hard to get the spring into position.

i wonder how well the factory tool works? how beefy it is, and does it make the job easier, than the cheapy ones.

Don't you guys know how to use the search function?
There is a cad drawing(ctsy Bernard) , as well as pictures and instructions on how to make this tool already posted.
The factory tool (or the home made one) is virtually the only safe way to remove front springs short of loosening the body mounts and lifting it till the springs unload. Much easier to use the proper tool.

I will warn you not to use cheap quality anything when making a tool that can do major damage if not made correctly

I agree..springs under pressure are quite the bomb when compressed!
Thanks for the refresher pics!

Jim,

You mention a CAD drawing, but I have been unable to find it.

BTW, my EFI install is almost complete. Just need to finalize throttle linkage and install a more reliable 24-12 volt converter. Started on the first attempt.

Wish I would have taken measurements and pic's of the factory one before I sent it back.

Erik, the only spec you need to make the tool is 10 1/2". That is what the spring must be compressed to to be removed/installed.
