FYI WARNING: Cheap Spring Compressor - pops loose while in use

[emerydc8]

Check out what happens to this spring at about 10 minutes into the video. I suspect it is the Chinese spring compressor.

That guy is pretty lucky he didn't get hit by those bits flying out. Scary

... I suspect it is the Chinese spring compressor...

It's not the spring compressor; it's the stupid user! If you look closely the spring compressor didn't break and that they used the same compressor to install the new springs.

From the start it's evident that they don't know what they are doing. If the spring was compressed properly they don't have to disconnect the ball joint and pry the old spring out; it would fall out of the perch. Also, I think I heard them say that this is the first time they used that type of spring compressor.

Let's not be quick to blame the Chinese. Just my 2 cents.

You're right.
First - they didn't compress the spring enough because they didn't know how much it has to be compressed.
Second - they didn't pay attention to a proper install of the "telescopic tensioner" into the the upper compression plate, so it simply slid out under pressure.

Those guys were damn lucky!

Watch carefully. It actually is a bad spring compressor, i.e. a faulty design. It is not a direct copy of the factory Klann as many Chinese/Taiwan compressors are, instead that one is a bad imitation. Specifically, note the clamping plate has a SLOT in it, so the plate can side off the shaft! And that is exactly what happened. This is a dangerous design. I would not use one of these. Ever. There are other Chinese/Taiwan compressors which are better. These guys are "experts" but they've never used a spring compressor before? Riiiiiiight.




See photos below of the factory Klann. Note that both plates have holes, not slots. Shameless plug: I have this exact unit for sale at the moment. Compare this to the screen shot of the YouBoob video, highlighting the slotted plate.

I was going to mention that, Dave, but you beat me to it.

Dave,

I also have the same clone compressor with hole. And if the spring is not compressed properly and you start moving (prying) it, the shaft will slip from the plate. As mentioned earlier, if the spring was compressed properly the top and bottom plate will be held in place by the grove and there's no need to pry the springs that caused the plate to slip.

With that said, I agree with you 100% that the design is flawed and did not consider the possibility that some "expert" with no experience would use it half haphazardly.

Maybe the camera angle is misleading, but it doesn't look like he was prying the spring at all. He was prying the lower control arm to make room for the spring.

dave you should show the other side of the klann plates! how they lock the plates in under pressure. looks like when he was pulling out the spring, he rested the plate on perch and slid it out....also you have to watch when starting to compress or decompress, you don't let the plate hit the perch.

Was it just me, or was that guy's reaction kind of funny, especially for national TV? Maybe it's just me. I like the Three Stooges too. Nyr Nyr Nyr.

Austin, it's nice to see you a bit on the forum again.

Enclosed a photo showing the backside of the compression plates.
The bottom plate at left, and the top plate at right.
(It's even your image Dave, it is the SPX set I bought from you.)

The three tabs on the compression bar locks into the three recesses on the top plate. When the plates are installed and ready to compress, they are angled so only one of the tabs may be fixed, however it is enough to avoid from sliding out - what exactly happened on the video due to a improper locking mechanism.
