Yesterday I went to a trip with my friend that included some 15-20cm water crossings. About 2 hours after the water crossings, a wierd problem started: at 1/3 to 1/2 throttle loud khhhh (Metal rubbing to metal) sounds starts to come from the variator. It happens in neutral too. So I opened the variator cover (And found out that there was a small hole in it, that's mean some water came it and probably caused this problem) and I noticed the sound starts when the plate I marked in blue touches the plate I marked in red (The blue plate comes closer to the red while the red doesn't move).

Here's the pic with the marks:

Anyone got an idea whats the problem is?

 

Clean and lube the rollers and weights in there. That should help as long as they didn't go bad.

 

Thanks for the quick reply. I've never disassembled the variator.. Should I take it to the dealer or can I do it alone? Do I need to use torque wrench for the screws?

 

You should be able to do this without taking it apart. At the very least you can see where a problem might be. Remove the belt (no tools needed-just slip it over the pulleys). Spray everything down with brake cleaner or carb cleaner. Take a dry lube or molly lube and spray the areas where the rollers slide and the rollers. Spray the weights where they hinge. Do not get lubricant on the pulley faces. If you do wipe it clean with brake cleaner. Let us know how it goes.

 

Also is the plate marked in blue actually touching the plate marked in red? If so you may have a broken spring.

 

The spring looks fine and it has resistence when I pressure it. I'm not sure it touches, it just looks like it, it might be just getting real close, does it makes sense?

I don't know where the rollers and the weights are located. All I know is that they are located on the red plate. I'm guessing they are on the opposite side of the spring. Am I right?

 

THe weights are connected to the moving half. There are three along the side held on with small bolts. They look like little boomarangs. The rollers roll up the sides of the moving face along the towers. they are connected to the stationary piece. they guide the moving piece as it goes down. You can take the top of the moving sheave off. Undo the main bolt to the crank and unscrew the six nuts on the outside. Just be carefull. the face is spring loaded. There is an x on both pieces makes sure to line them up when putting back together. The torque on the six bolts is 7 ft/lbs or 90 inch/lbs. The torque on the crank bolt is 40 ft/lbs.

It's already night here in Israel so i'll try to clean the weights and rollers tomorrow and see if it helps.

 

Isreal? Wow, how neat is that? [img]i/expressions/face-icon-small-smile.gif[/img][img]i/expressions/face-icon-small-shocked.gif[/img]

 

Problem solved! [img]i/expressions/face-icon-small-happy.gif[/img] I did what you told me: clean with carb cleaner and grease the weights and rollers and the sound is gone. Thanks [img]i/expressions/face-icon-small-smile.gif[/img]
