This weekend my RZR stopped in it’s tracks. It was bleeding all over and there were chunks of aluminum on the ground.
The rear end blew to bits.:sad:

The RZR is a 2012 with very little miles. I think it’s got under 150 hours Maybe closer to 100. I’ll have to check and update the thread. It’s basically new.
Anyways, first I was extremely disappointed at how much time and tools it takes to get the rear end out. This should take like 30 minutes, but it took three or four hours. There is a wild mix of hardware including a variety of sizes and both metric and standard. Then, most of the hardware is difficult to get to. My 11 year old had to use his small hands to reach some of the bolts after they were loosened. Really looking forward to putting a new one back in.:sad:
I was thinking what would I have done if this happened on a trail!!!!?? I was very fortunate to have broken down near my shop and dragged it back with my Ranger, but even that was a challenge.
Next, when finally got the thing out, the input spline was broken. At first I thought this was what happened. But that wouldn’t explain the pinion jamming through the case.
Then I noticed that the nut was completely off. At first I thought it might have sheared off, but all the threads were fine.
I talked to somebody at Hawk Engineering that used to sell the heavy duty housings and he confirmed that they often have problems with this and they typically remove the nut and locktite it on.
When the pinion nut comes off, the pinion gear slides between the ring gear and the housing causing a catastrophe.
My question is if Polaris is taking care of their customers on this? This is a clearly a design flaw. I’m out $1900 for what is clearly poor engineering.
I’m thinking there are millions upon millions of cars on the road with differentials driving tens and hundreds of thousands of miles and I’ve never heard of a pinion nut loosening up.
Another thing is that this is clearly either a design problem or there are random RZR’s that weren’t torqued properly. I don’t know, but i know it should never happen, no matter what.
Has anybody else had this problem or know of anybody that has?
Any info would be great.
I had a 1984 atc a while back and a few of the parts seem the same. I like the shaft drive, less so running over my own leg.
Quick question, the air filter was caked. I’ve ordered a new one but I’m not sure what it includes. The trouble is the stabilizer bracket that comes off the metal screen can part. I couldn’t see how the rubber part separated from the can part so I cut it all apart. I still can’t make heads of it, what am I missing???????
I’m going to use the Nuvi for street use only and the rear view camera… I just ordered a Ram Mount to use my 7 in Samsung Tablet for a Off Road GPS! Can’t beat the free apps and free TOPO Maps plus my tablet is on my data plan so it wil receive any map updates.
I’ll post some photos in the next day or so!
Interested in sintered, I browsed the internet and this Forum and came to the conclusion the severe duty sintered offered by Race Driven would fit my needs. I ordered a set and received them Monday. However, they looked not much thicker than the ones I am about to replace. Measured the new at 0.14.
Called Race Driven on Tuesday to ask why their sintered pads were so thin and received an answer that because of the sintering the thickness does not need to be as thick as organics, though will outlast organics by a factor of five depending upon use. Made sense until I asked the next question –
What is the service limit on the sintered? Or rather, at what thickness should I consider replacement pads?
Their answer was "Nobody has ever asked that question." Really????? I posed it again that as a preventive maintenance item, I need to know. She put me on hold, then came back stating nobody knew, but most folks order rotors at the same time as pads. Really?????? She then stated she would ask the owner and get back to me.
Today, I called again and lucked out (??) by getting the same lady as the day before. She said the owner said "they don’t have a clue and most people replace pads when they are worn out." Really??????????
So to make a long story short, does anyone know what the service limit is on sintered pads? Why destroy rotors when it is totally unnecessary.
