Look Pivot Heel Wobble

post #1 of 11
Thread Starter 
I've got some unused Look P12 Pivot bindings that have a little side-to-side wobble in the heel between the metal pivoting "cradle" and the fixed mounting structure attached to the ski. I'd say the total movement is 0.5 mm measured with a feeler gauge between those two pieces (under one side of the heel) from one limit of wobble to the other. Is this typical on the Look/Rossi Pivot heels?

Seems like it would result in less precise control over ski edging, which is surprising since I thought these bindings were considered to have the most secure feel.

Not only will it result in less presiscion control, it will also relsut in differnt releasing careceristics. I'm not sure about any way to fix it, but check to make sure they forward pressure is right.

Also, how worn are your boots? If you walk around in em a lot, the heels and toes will get worn down, and will no longer properly fit almost any bindings, that could be it.

If its neither of these things, get new bindings, you will probably be able to warranty them.

My guess is the wobble is without the boot in the binding. That is totally normal with the pivot heel. Now if it's wobbling like that with the boot locked in you may have an issue...but I doubt that's the case.

The pivot heel slides on a track that is mounted to the ski. The track must slide freely fore and aft to adjust for forward pressure and boot size. I detect no lateral movement between the track and the plate that holds the pivot heel in place, but there is some of rotation and flex if you grasp the heel piece and twist or try to move it. If the bindings are not yet mounted, that is probably the issue. If mounted, it kind of depends where the movement is occurring. Some movement is normal.

I've owned several of these heels over the years (have a pair on some Rossis currently), and I think EC is right: The later versions of the real rotary heel had some play unloaded because of the partial pivot. In the older ones, there was full pivot and plenty of play. In both cases, it went away once the bindings were engaged.

If you don't want them, I'll buy them off you.

Sorry man, but I gotta disagree.

I have four pairs of skis, and none of them have ANY play between boot and binding.

As better explained by XEC above, the play is without the boot in the binding. They are solid with the boot clamped. We posted at the same time, and I never saw that reply before I posted.

Thanks everyone for your quick responses.

The play I'm describing is NOT between boot and binding. It's between the pivoting portion (the silver cradle) and the non-pivoting part that slides on adjustment rails for forward pressure adjustment, and it's there whether there's a boot engaged or not.

Like Cirquerider says, there is no detectable play between the fixed rails and the adjustable piece, with or without a boot in place. With a boot engaged and the ski firmly held down on a hard floor, the movement at the top of the cuff is probably 1/2". BTW, I've just checked this movement with a Marker 1300 Piston and also my old Marker M1 SC's with the MRR heel, all with a boot in place with correct forward pressure. The M1 SC's have the most wobble (more then 1" at the cuff and it happens at both toe and turntable heel) and the 1300 Pistons are about the same as the P12. In all of them, the boot is not moving in the binding. It's the binding moving within its mount. (Yes, they are all correctly screwed down.)

I'll keep that in mind, but right now I'm tempted to use them instead of the 1300 Pistons. But given the warmth yesterday at Crystal Mountain, it may be next year before I get a chance.

Look Ps can develop some play in the heel, it's a known weakness. If everything is correctly adjusted and there is still some wobble with the boot on, you may want to warranty them.

I see, that was a bit confusing.

In that case (if that was the original poster's problem) my mojo 15's (and all mojo 15's) do exactly the same thing, and its not big deal. They're solid once you click in.

That's what I was talking about. That "cradle" can be wiggled side-to-side when the boot is not in. If it does that with the boot engaged in the binding I would have them checked out.

How's your forward pressure? With the boot in the binding how deep into the notch is the screw at the back of binding? Wouldn't be the first time a shop tard didn't set that right.

Also with rossi/look bindings, if the fwd pressure is adjusted with the boot in it can strip the worm screw and the heel piece can wiggle back loosening the fit. I highly doubt this is the case since yours are unused though - something to remember when adjusting them yourself though.
