Question Removing pinch clamps

Does anyone know how to remove these stupid pinch clamps, #6? These are also on the power steering hoses going to the reservoir.



Thanks.

Those are meant for one time use. I usually get it off any way I can and replace it with a hose clamp

Thanks--that makes perfect sense. I was trying to figure out how the engineering works behind this and they look rather tedious to put on. I am just wondering what the tool looks like.

I am definitely replacing these with the good ol'e Norma Torro worm clamps that can be seen on the intake boots, MAF, and on the secondary air pump hose.

I treat them as consumable too. Pry them off, and replace with new.

Thanks.
I cut them off with a large pair of side cutters, and replace with the regular worm drive type of clamp. You can buy new "BMW" clamps that came with the car, and the tool to install them, there is a pair of pliers that look like cv joint boot clamp pliers. They might be the same tool, I have never replaced either clamps.

Life is easier if you don't try to understand how the engineering works on anything BMW makes. lol

I quit years ago!

Jam a screw driver into the small loop.

BMW use that kind of clamps because it is easier to control the clamping force and eliminate the risk of cutting the hoses. Their engineering reasoning is very sound.

From what I have been told by a few mechanic friends I know (top level in my book) tell me that the best hose clamps are the "spring" type that Asian cars use. They let the hose expand a bit as the hose expand due to heat. They wont dig into the hose as a screw style hose clamp can. I have never said hose so many times in one sentence.











Hose.

Has anyone had any luck removing and replacing these in situ? I've got weeping hoses and I don't want to remove the hose to replace it. I figure I can cut the clamp off, but can I get a worm gear one on without removing the hose?

As said, side cutters...dykes.

Someone helped me in one of my threads...showed that they cut the 'bulb' off...'mushroom' from the cross section. Take the cutters and hold them in line with the clamp, so you're cutting across the section that was squeezed together for tightness.
