Deceleration Noise

I have a 2007 660 and engine is stock. When I decel without using brake there is no noise, but when I decel and use the brake there is a horrible almost gring noise that sounds like it is coming from the clutch belt area. After an hour or so of driving...the noise started to do it on decel without using brakes....has anyone had this problem or heard of this before? Thanks for any assistance...

I would look at your rear brake which is attached to the driveline at the final drive.

BTW: Starting in '08, the 700's had real rear disc brakes and the former rear brake is only used for parking.

Sounds like the one way bearing to me. I had the same issue and that took care of it. Terrible grinding noise on decel. Sounds like something is getting chewed up. Do a search on one-way bearing. Easy enough to change. Pretty sure there's a step by step.

I would say either.

If it makes it without the brakes it is most likely the one way bearing in the wet clutch.

You can gamble by buying the bearing and a gasket and installing them but the surfaces it rides on, on the two different halves of the wet clutch may have damage or worn so the new on might do same thing but you would only be gambling on a gasket and the oil you would have to replace if you go back in.

Call if you want more info and how to do this.

Spend $10 and replace your brakes before you dig into your wet clutch area. If that doesn't fix it, then look into your one way. When my rear brakes wore out, it sounds like my machine was going into a paper shredder.

so I inspected the rear brake/ parking brake and it seems to be intact and pads are hardly worn. I removed both primary and secondary sheaves and checked the one-way bearing....seems to be the problem. It doesn't spin totally smooth and it spins both directions...ordered parts and also spoke to James at JBS and ordered complete sheave kit..figured while i'm in there...right??? James is a very knowlegdeable guy and super nice. Thanks for everyones input...this is a great forum.

You will be very happy with the sheave also. Go ahead and get everything you need to change oil. Drain the engine oil before you pull the cover over the wet clutch (if you haven't already) your going to lose some.

Hi Roger 33. The problem that you describe is identical to mine. I am not sure if I could have penned such an accurate description of the problem myself. I have read may posts in this forum and the one-way bearing is to blame for a host of noise issues. Some descriptions are very different to yours and receive the same one-way bearing alert response.

Did you manage to sort your problem out with replacing the one-way bearing?
Was it a major exercise requiring special tools?
Is it and expensive exercise?

In my case the noise is associated with the braking. Not immediately the brake is applied, but it begins to grind or chatter just before the vehicle comes to a holt. (grinds to a holt!) It sounds very much like metal on metal and happens when breaking in forward and reverse. The location of the noise appears to come from behind the seat beneath the load bin and not beneath the seat area where the transmission is located, which leads me to suspect brakes.

I am hoping that it is mud and small stones that have accumulated in drive shaft brake assembly, although I have run my fingers over the brake disk and it appears to be in good condition. I also struggle with the notion that the disks wear out as in my experience virtually all braking on a Rhino happens by simply taking ones foot off the gas.

I am equally confused that a bearing that makes that type of destructive noise can continue to function. My rhino is running perfectly, except for this grinding noise that is associated with braking.

To all you guys who have responded to Roger, thanks for your inputs. It really helps to know that there are people with knowledge and so willing to assist.

You picked the right guy to call. James is the man. And the sheave is "The Sheave " to have. Good luck.

I am convinced it is the one way bearing and keep in mind it is not really a bearing at all, it is just called that. Actually it a ring of what looks like camshaft lobes, they lay over going one direction and then stand up going the other direction basically locking the wet clutch to the drum portion giving you the engine braking.

If all you need is the one way bearing then it is about $80 retail and you need a gasket for the cover plus oil.

I would be looking at the surfaces it runs on too while I was in there but you aren't risking but a another gasket and oil if putting a new one in and still having to go back in because the surfaces it rides on are damaged too much.

Special tools? no
Easy to do? yes just time consuming maybe two hours for me, but I done a bunch so maybe two to three first time.

Feel free to call me, I can tell you how to do it and what to look for. I don't sell those bearings and gaskets though. But still don't mind helping you with it.

Ace Not one way bearing

I replaced the one way bearing and complete sheav kit with spring and weights included. The noise is still very much there and so far nothing i've done has even changed the noise. I have inspected the rear/parking brake assy and have not found anything there. Is anyone familiar with the auto braking when letting off the gas pedal. Noise seems to be coming from the trans area.....

Did you inspect the surfaces that the one-way clutch ("bearing") runs on while you were in there? There will be a surface that the inside of the lobes run on and a surface that the outside of the lobes run on. These should be smooth and unblemished by wear marks.

Another thing that can cause a lot of noise in that area is a missing or loose cage over the primary CVT pulley, The tip of the long shaft that carries the pulley is stabilized by the bearing in the support cage. Perhaps if that bearing is bad you would have that shaft rattling around at certain speeds?
