2005 750 Brute Force 4x4i.........Belt light came on and in limp mode .........165 hrs........
OK ...I adjusted the belt by taking out the a shim to get it in specs on the belt deflection.....put it all back....reset the belt light........everything works fine except when its in Low Range. I can take off for a bit in low range and let off and it sounds like every gear in the machine has been stripped out. It sounds like the noise is @ or under the converter pully cover. I've got the cover off now and looking into the engine brake control, the drive pully and so forth but haven't checked all specs (measurements) yet.
The noise is grinding, clattering, and then when the machine is almost stopped it clears up.............

Thanks for your help and experience!!!!!!!!!!!!!

Is the noise only present when you are de-accellerating? Or can you hear it when accelerating aswell? If it is only when you are letting off the throttle, you might want to look at your engine brake inside the CVT cover. Perhaps the actuator came out of the pin that it rides in? I'm just guessing, but its easy to pull the three bolts to check.

My shift linkage is noisy only when I am in Low, could that be what you are hearing.

Check your motor mount bolts, bottom front and rear. They are notorious for being loose. Easy fix if that's it.

That ties into the shift linkage theory, the engine moves under load, and that shifts the position of the linkage.
Both the motor mounts being loose and the linkage being out of adjustment without the mounts being loose were very common problems on SRA BF's and Prairies. It always happens in low range and when letting off the throttle.
I think bfb650b2 is safe; nothing should be broken. I thought mine was going to blow up the first time it happened, lol.

did you take any of the clutches off? and if so did you torque them to the right foot pound?

It's the linkage adjustment or the motor mounts. 'Nuff said.

The primary and secondary or drive pully and driven pully.........
Yes they were taken off and torqued correctly to 69 ft. lbs. when reinstalled as the service manual states.

Hey (me waving hand to get your attention) Camo Joe, this IS the problem. Don't worry about the clutches; they're fine.

Camo Joe jumping up and down!!!!!!!!!!!

NovaKaw650........."Nuff said"

"Nuff said" is RIGHT ! You guys were right on. Nothing like experience.

I checked the motor mounts......front bottom and upper rear and brackets and put some more torque on them, adjusted the shifter linkage (which is really sensitive)........took it out for a test drive and "Hell Yes!"
I dogged it hard several times accelerating and decelerating with no braking and everything worked and sounded as it should. Now gonna install a horn and button and wake up the neighbors about midnight.........

Again .....Thanks for your help and keep your powder dry!

The linkage adjustment is very sensitive.
Time to ride!
