Clutch Slipping and Squealing

[Landon54]

I noticed after I bought my 07 IQ 440 that whenever I go hard on the throttle, the belt makes a squealing sound and it's very annoying. It doesn't make the noise when I'm driving at a steady speed or at idle, but whenever I try to accelerate faster it does. I know they're still the original springs in both the primary and secondary. It's the same thing with a new belt also. When I had the secondary off I heard a small rattle whenever I shook it. Would the springs be the reason for the squeal?

Thanks

It could be weak springs. Also take off both clutches and wash the sheaves in very hot soapy water to get the old rubber deposits out of the aluminum. Rinse well with clear water and let dry. Do the same with the belt. Scrub the sides where it contacts the sheaves with a bristle brush in hot soapy water and rinse. That should stop the slipping if it is due to glazing of sheaves and belt.
You may want to look inside the secondary if something is rattling in there as that isn't normal.

This may sound dumb but do you have the correct belt?

Ya I have the right belt. Probably gonna take apart the secondary clutch and check it out.

This may sound dumb but do you have the correct belt?

And the belt deflection set correctly?


The rattle noise in the secondary could be a bad roller or a broken spring as well.

The rattle in the secondary was a the tip of a broken 1/4" bolt that was used for changing belts. the belt deflection seemed pretty good but ill check it later.
