2012 RZR XP 900 Build - Page 2

93 Krawler · 07-26-2017, 11:45 AM

I was checking the machine over and found I had cracked the rack and pinion housing where It bolts up. So, time for upgrade number, uh, I lost count.
Bought the Super ATV rack boss. This one better hold up.

Glad I replaced the rack. The old one was cracked in to places. Comes with some nice beefy heims.

Been wanting to replace my factory seats with suspension seats. Went with the PRP GT-SE rzr seats with the +2" width. They make the old seats look tiny. Very comfy and roomy.

Looks very comfy. I'll have to sit in them next time.

I meant to ask at the meeting and I forgot: What are your plans for the old seats? They're valuable enough to sell, right?

93 Krawler · 08-11-2017, 04:27 PM

Yes, they're great shape. The plan was to keep them in case I sold the 900 and got a newer one. Sell it with the stock seats and keep the new ones for the new machine.

Cool. Good plan. I just wanted to make sure they weren't going in the garbage...

93 Krawler · 09-23-2017, 09:31 PM

The past few rides I've noticed the front diff making a ratchet noise when I'm getting on it hard. Opened up the diff up today to see what's up.

Found a tang missing and some bent ones on the armature plate.

I bought a heavy-duty sprag to put in because I figured it was cracked but the old one was in great shape. Unfortunately I found that I had cracked the ring and pinion. So I got to buy a new one of those as well.

While I had the diff out I went ahead and replaced the three U joints and the carrier bearing on the drive shaft.

I ordered a new ring and pinion and found out that the new ring and pinion does not exactly fit like my old one. So I'm hoping I can get the lip milled off of the new ring gear to match my old one. I'm already into this diff for $600. Super ATV website says it should fit but it won't. Evidently there were certain years on the XP 900 that it would not fit. You can see in the picture that there is a ring connecting the ring gear teeth on the new one and not on the old one, that part needs to be milled off.

"Edit" I got the lip milled off and it worked great. Thanks for the help Chris.

HD Extreme has some nice upgraded parts for the front RZR diffs. I bought their HD armature plate. This is way stronger than the stock one. They now have 2 options, strong and stronger. The one for the 800 or 900 XP has 5 or 10 tabs, and the 1000 XP has 6 or 12 tabs. I believe with that many tabs gripping the sprag carrier, you are less likely to crack the sprag. There is also more area for the magnet to grip.
I tested it out at Harlan and the diff worked great.

The stock one on top of the new one.

I started having problems with my front diff at Winrock. I think my last trip to Harlan took a toll on it. All the new parts I put in last year are toast. Superatv now has a steel sprag that they claim is indestructible. That sounds like a challenge to me

I believe 100% that you will be the person to prove them wrong and give them a bad name.

Kevin it's time to park that $$ pit and get your new rig together.
Your starting to spend more time and $$ in that thing than you are wheeling it.

You are proof that those things are not cut out for what you wanna do with it.

Says the guy with a jacked up ring and pinion... Hey, put your factory parts back on your yota and tell me how it does...

Most of our rigs weren't made for this abuse.

So how much have you spent this year on your rig?

93 Krawler · 07-19-2018, 12:49 PM

I got the front diff back together. Superatv has a lifetime warranty on their ring and pinion set and the sprag, so that cost me zero dollars. They also upgraded me to the 4140 steel sprag for free. I did have to buy a rebuild kit and a new armature plate. Between the 8 tab plate and the steel sprag, it should hold together better.

I believe the reason I broke the bearing carrier is I didn't know you were supposed to use Loctite 603 retaining compound on the bearing. That might have kept the c clip groove from breaking off. It will be on there from now on, so we will see if it happens again.

I'm ready to see progress and your new Rig on the trail that can handle abuse.
