How often do I grease the swingarm bearings?

New sport for me, I am a woods rider in Michigan. I was wondering how often am I going to have to grease the swingarm bearings?

Personally I'd recomend at least once a year, or whenever you have the engine out for servicing. It's a virtually free job that you can knock over in 1/2 a day that will save you a heap of money in the long run. If you must wash your bike, avoid spraying high pressure water in the direction of the seals and bearings. Id recomend that you invest in a tube of quality molybdenum-disulfide grease as it is good for this application.

my 2 cents worth,

While we are on this subject again, I was wondering if anyone added a zerek fitting to the swingarm without taking the swingarm apart? What would be worst? Waiting for the bearings to need to be replaced or adding the zerek with the possiblity of a small amount of metal shavings mixed in the grease. Which would fail first? :)

I would say the addition of metal shavings. In my opinion, the zerk isn't the 'be all and end all' of bearing lubrication. The reason a zerk isn't used in many roller bearing applications is because it doesnt do a very good job of evenly greasing the bearing, and can also cause seal damage. Your best bet is to grease the bearings manually and dont use the pressure washer to try and fill them with water.

A TTer put zerks in a year or so ago, nice writeup with photo's. Zerks were done with the linkage apart. The problem with the setup was that the seals were pushed off when adding grease. I grease mine once a year.

About how long does it take to grease the swingarm bearings? Ive never done it but figure I need to before the season begins. Does anyone have any tips or pics to do this? Thanks, D :):D :D

Check this out, compliments of Wrooster. Most do not remove the needle bearings to regrease but if you really want to do it right this is very good information. :)

Has anyone noticed in the 450 manual, Yamaha claims to use a "special" dry lube on the swingarm/linkage bearings that make them "maintenance free." Does anyone know what this wonderstuff is? I can't see just ignoring these bearings, but I would like to use the same if it's any good.

A lot of people recommend removing the string cheese, but it isn't necessary. I listened to my buds and pulled it apart only to find that they were mint. Since I had it apart I gave it the what the hell. Save yourself the trouble and don't bother. The string cheese was just fine in mine, and I'm sure yours won't be bad either.

I will ditto this, the string cheese was in tact and looked fine, except one bearing which was developing rust the string cheese was toast. I had never done the job either and I just did it about 2 weeks ago. Read the above link to the FAQ that wrooster wrote up and you will have no problems, Just have the manual handy. I am no mechanic and I found the job easy enough to do just for the hell of it and to make sure everthing is good.

I finished the job myself this last weekend. One bearing that was in bad shape was the bottom shock mount roller bearing. Looked like it was packed in dirt. I've never used a pressure washer on it and have about 600 miles on it (~1 yr). The top ball-type bearing on the shock was pretty dry also. I cleaned it and greased as best I could. All the swingarm and linkage looked good - gave a good gob of grease anyway.
