Xp 1000 rear knuckle

Bit the bullet and bought new bearings for both rear knuckles so took the worse one off and easily popped out the snap ring and turned it over , found a big socket to tap the old bearing out and poof it falls out on the bench without tapping it . Hmmmm that’s weird then put the new one in place had to do a fair amount pounding to get it seated till the last half inch and then it dropped in . Put it all back together and still almost the same amount of play , bushings are tight so to my surprise the bearing is loose in the knuckle. My luck sucks !

That don't sound good.
Did you use OEM bearings?
Had the old one frozen up and spun so that the bearing carrier is worn?
Did you use Loctite 603 retaining compound as called for in the service manual when installing?

Cecco racing makes steel front and rear bearing carriers if you have to replace yours.

Well the locking compound sounds like a worth while option , there’s play on the other side too which was replaced by the dealer I got it from , I’ll try it !

Loctite 603 is the stuff. It only takes a light coat. It acts as a lubricant when installing and then locks the bearing it place when dried. You need to apply a little heat to soften it for removing the old bearing next time and make sure to remove any residue from the knuckle before installing the new bearing. Same stuff used by Polaris when they are originally installed.

I can understand using the loctite, but in his situation it seems as if the bearing carrier got rounded out or something. I don't think loctite is the right thing to use when bearings can easily fall out. Heck on my 2010 I still need to use my press to press them in an out.

Oh yeah, I totally agree. The retaining compound won't FIX a worn out carrier. That's not what its for. It's used on the bearings to hold them in place from the factory and is supposed to be used when replacing them and it's released with heat. A press is definitely the preferred way to remove and install bearings. Knocking them out and in with a hammer will work in a pinch, but unless you're very careful and freeze the new bearing and use a LOT of heat on the knuckle so the old one comes out easy and the new one taps in easily, you will destroy the new bearing and possibly the knuckle. It takes a lot of finesse to do it that way. If you get too hot you'll melt the grease out and damage the new bearing and if you beat it in without heat you're gonna damage the bearing and/or the knuckle and it won't last very long either.

Polman is this product harder/ better than red locktight or is it red locktight ??
reason i ask is i want to put something in lower steering stem splines as my quad now has ridiculous play in there at only 2500 miles .

No Dan, the 603 is green and is labeled as a "retaining compound" rather than thread locker. It is specifically called for to install the wheel bearings. Not sure how it compares to the red thread locker?? It would probably work but I can't say. You might get on Loctite's website and see what they say about it.
Polaris calls for 620 used with a primer on the drive clutch spider threads. I just don't know what the specific properties of the different types and how they compare.

I just thought of something else Dan. The 603 is kinda thick stuff so it wouldn't run down in the crevice on the steering fix Autosport was talking about. The red would probably be better for that application.
