P500 Transmission disengaging

[25yrds]

I've just noticed recently, that sometimes when going down a hill slowly, sometimes the transmission seems to "disengage" and freewheel. If I blip the throttle it immediately re-engages. Reminds me of a Polaris. Is this normal? I don't recall it doing in the past.

Slowly…like walking pace 3 mph or like 10 mph?
Hill…like 5 or like 20 or like 45 degrees?
Might give a little more insight for replies

doesn't sound normal. with mine, it will freewheel when downshifting, between gears engaging. doesn't sound like your issue though.

Yes. When going very slow. Only at idle. Never when there's actual back pressure. It's really not a big deal. Just don't remember it ever doing it before. I pull a fairly heavy trailer down a pretty short(200 yards) and fairly steep hill sometimes. I use the brakes a lot. Sometimes when I let off of the brakes it freewheels like it's in neutral. Like I said, a blip on the throttle and it immediately goes back into gear(2nd usually).

I believe it’s a centrifugal clutch on the P5. It’s possible it’s not spinning fast enough to be engaged. The blip of the throttle engages it and engine braking is back.

Someone smarter than me might be able to say for sure though

I tend to think you're right. Was just wondering if anyone else had experienced this.

This little p500 has been an awesome machine! The same trailer that I mentioned is also pulled up the hill with it. Mostly sand and a little bit of "pit run" gravel. Pretty much only 4x4's can get up the hill. The trailer is heavy enough that it gets to pushing me down the hill. I lock it in 4x so the back pressure will be, basically, like braking.

At low speed, usally with rough terrain the centrifugal clutch will disengage.
If you don't blip the throttle the vehicle is a hand full.
It wants to charge down hill well above the expected level.

Don't know what year yours is BUT mine is 2017 full manual and it never free wheels .

I've not had that problem either.

Nor I . . .

My 2017 doesn’t have the Polaris effect and always use manual mode for hills. Does it do it in manual, auto or both? - What year is your Pioneer?
Have you tried a clutch adjustment? - Just thinking if your history of heavy downhill loads/engine braking has caused some minor centrifugal clutch wear, and having experienced that the adjustment range is very small to find the sweet spot. Best of luck.

The centrifugal clutch has a one way bearing in it that keeps it from freewheeling, even at idle. That is bad.

Mine does it occasionally....when all the stars align sort of occasionally. I'm not too concerned about it.

FYI, a clutch adjustment won't do anything for this, the centrifugal clutch is separate from the "main" clutch, they are two different systems. Take a look at the parts schematic and you'll see what I mean.

Also, mine is a '16, manual only

It's an '18. I have adjusted the clutch. Not for this "problem" anyways. I pretty much never put it in a/t. I guess time will tell.

It's, actually, only done it 2 or 3 times. And I can't get it to do it if I try

change the one way bearing it will be nice after,

 

[gillbert]

if the one way bearing is not working you wil have too change it to solve the problem
