Hole in rear gearbox

Attachment 582124

I have a 2015 Rzr 1K with 13.5 K miles. Yesterday I went for a ride and heard this terrible noise from the rear gear case. I found a hole in the side of the gearbox next to the shift cable. I have seen this at least one other time here. Has anyone else seen this or know what caused it? A new gearbox is about $2900 + labor. Two years ago my front transfer case went bad and had to be replaced $1600 + labor. I’m just an easy trail rider and don’t abuse my equipment and keep up on all Maint. Schedules.

Sorry the photo is sideways. The forum kept doing this and wouldn’t post it straightened. A Honda Talon my be in my future if Polaris parts keep falling apart.

Re: Hole in rear gearbox

Probably a bad bearing. Sucks cause might as well get a whole new transaxle cause the half piece is pretty pricey.

Re: Hole in rear gearbox

I like to make lemonade out of lemons Iíve always wanted to tear into a transmission. A friend of mine did the same thing as you. We had another friend that had an extra one so when he pulled his out I asked him if I could have it. I figured if I screwed up tearing it apart and putting it back together it wasnít a big deal. They are way easier to take apart and fix than most people realize. There are videos on how to do it. On mine he broke the snorkel gear and put a hole in the side of the case. You can get on super atv and buy heavy duty cases. You can upgrade as much as you want with heavy duty stuff or just fix it. You could even do a gear reduction while you are in there. Just take your time and lay things out and take pictures as you go so if you get stuck you can refer to them. I wouldnít put a used one back in cause it could happen again . Iíd upgrade and build it . You can have a better transmission for the price you pay for a used one.
SuperATV, RWB713 and Rockwerx like this.

I've spent most of my money on women, guns, and Harleys. The rest I just wasted.

Re: Hole in rear gearbox

Yes, this is a bearing failure. You might be able to repair this relatively inexpensively, but you would need to remove the transmission and split the case to know for sure. Really depends how much other debris damage there is.

Extended warranty would typically cover this as long as you had service records for it, but there is always the potential for an argument over aftermarket parts.

Re: Hole in rear gearbox

I had a similar failure in my 900 XP years ago. It turned out to be a bad bearing. The warranty took care of it and replaced the half the case, bearing, and took care of labor (less than 1000$). Once youíre inside you should update the output shaft and replace the rest of the bearings with SKF if you plan to put another 13,000 miles on it.

Re: Hole in rear gearbox

Damn, sorry to hear that Roger. I've talked with you before and know you are pretty easy on your equipment.
I've read that the bearings and the reverse chain just plain suck on the XP's, and I always have that fear in mind. I figure at some point I'll pull the trans and replace the bearings and chain before they break...when is the question though. I've got 2800 on the machine now. Change the fluids every 15 hrs or so, if that helps or not , who knows.

i always said keeping fluid clean helps but who knows, and btw what fluids do you use in your front and rear cases? Polaris or other? I just got a xp upgraded from 900 and I always have that fear of reverse chain and bearings also

I changed the transmission fluid every 500 miles on my XP 900 and had a bearing failure. The XP1000 Iíd often drain and refill around every 200-250 miles and still had an upper bearing failure. Roughly 800 miles later I broke the output shaft. I never broke a reverse chain, rear axle, or even blew a belt. The Turbo drive train is a lot better.

Re: Hole in rear gearbox

Well the verdict is in,
A bearing in the rear gearbox came lose and ate a hole in the gearbox. Then they found a bad rear universal joint and a bad bearing and seal in the front left axle at the transfer case. Add complete fluid change and set set of Tensor Regulator tires and we are at $7K.

Re: Hole in rear gearbox

Ouch ! That is a bit steep it seems. Are you doing any of the work yourself ?

Thatís crazy expensive. A complete transmission is less than $3000. You can have the entire front differential rebuilt with new bearings and seals for well under $1000. Even adding labor at $120 an hour, youíre well under $5000.

Iíd question how they came up with that number.
