Full Version: why no grease fittings on prox suspension?
I have a proxr 800, i just pulled the skid out and put in a reinforcement axle betveen the torque stops, and realized that all mount bushings have absolutly no grease fittings, and no way to lube these without pulling the skid, i have never seen anything so stupid, what do you say guys..?? :doh: /A
LOL. i just pulled mine too and was thinkin the same thing. From the looks of it you could add some pretty easily. Less friction=better suspension right? I just bought replacement bushings for the front skid shock on the 92 440 and there a mm shorter then the one i cut out (totally froze to the bolt) which would make the rubber hit the mounts and bind...WTF polaris?
I added grease zerks to my skid. You could see where the bushings were rubbing and starting to wear. Rust also starts to form in there from it being wet all the time.
The ProX uses oilite bushings and coated shafts for the front arm. No lube is needed. I put almost 6500 miles on my last proX skid. No appreciable wear to the bushings occcured. Install grease fittings if you like. They're not required. Unless the skid is twisted, I've never seen a worn out oilite.

what he said.... no problems, adding grease zerks isnt a good idea... ive got 6500 also on one of mine nothin wrong with it. to each his own though.
im adding six grease fittings to the mountings in the skid anyway, my cousins proxr 800 was not very nice in the skid after just 2000km, the bushings had worn out totally, so some grease could never hurt...

If you knew anything about self lubricating bearings you would not add any grease to them. It will cause them to get soft and they will crumble over time. If you go with zerks you should change out the bushings to plain bearings. But do what you want.
what he said^^^ you mine as well grease your clutch to make it smoother at the same time... see what i mean
yep....

I've heard that grease will make oilite get soft, but mines been fine for over a year. The suspension was starting to squeak, and I wasnt going to listen to that. And sorry, but rust in the joints isnt what I'd call good.

Not the same.

i have added some pics of my grease fittings, its a picknick to grease the skid now when i place in the machine... :div20:
