Greasing swingarm bearings without removing wheel

Post by vchris » 03:25 pm Aug 07 2019

Hey guys, got my first dirt bike, a KDX220 2005. I did my first ride 2 weeks ago and the bike was great. Noticed it was really squeaky and it seemed to come from the rear suspension, the swingarm bolt more specifically. I'd like to wait for winter for a full grease job. Is it acceptable to only remove the swingarm bolt, grease it and slide it back in? As long as it's not seized of course.

On my older one there are sleeves in there that neeed to come out to grease it. Check out your parts diagram on partzilla.com.

Welcome to kdxrider.net.

If it is already squeaking, then the time to act is now. Maybe you won't have to instantly replace parts.

No, you can't just take the swingarm bolt out and get grease onto the bearings.

I sincerely wish you luck on it. They can be tough!

Short answer, no. Your next purchase should be a service manual if you don't already have one. At minimum you'll need to grease the bearings. Might as well do the linkage, shock and wheel bearings while you have it apart. You'll need a heat gun and a freezer to put the bearings in for a couple of hours before installing new ones. (If you have to replace bearings, which if they are squeezing, is likely.)

Pulled the swingarm this weekend. Left bearing is good but right is really dirty. I'll be replacing the right one only and greasing the left. I'm wondering isn't there a bearing between the swingarm, on the engine end? That's gotta be terrible to change?

I see there is one but no one seems to be documenting it. How is it called if not swingarm bearing? Any videos on this?

I am not sure which bearing you are talking about. Can you post a link and the reference number on the picture? Thanks!

Where’s the bearing? Part #? Mine doesn’t have a bearing in there.

No bearing there, just a hollow section.

92042 are pins to help with alignment.

I just stuff mine with grease and move on with my life. It’s too tight for a bearing.

Engine doesn't move, swing arm does. Clean, inspect, grease (if good) or replace the swing arm bearings (and seals!). Grease the bolt before you reinstall. While you're down there, do the same for all the linkage bearings and shock bearing as well. Bike will handle better!

Yup. The bolt doesn’t rotate whatsoever, neither does the motor (hopefully)

The bolt and engine SHOULDN'T move. If either does, then there is a much bigger problem.

DO put some grease / anti-seize or SOMETHING in there to ease removal of the bolt in the future.

Just a friendly reminder that the Kawasaki service manual specifically calls out a molybdenum grease for the swingarm and lower rear shock linkage bearings. I believe the reason for this is that the movement of the joints are low speed (unlike a car wheel bearing at 80 MPH) but very high pressure (lots of compressive forces on the bearing rollers). "moly" grease is the black stuff. I have a tube tucked away specific for rear suspensions.

Bel-ray Waterproof grease and Maxima grease have worked well for me.
