Title: Fork Seal and Fork Oil Recommendations
Post by Anameofsomesort on 05/31/23 at 23:35:54

Need to replace my fork seals and fork oil on my Savage and can't seem to find great information on if I should just go OEM or if there is a better 3rd party option. I would like to put off having to replace them again as long as possible, and that's going to mean getting the best seals I can possibly find.

I also am not sure what weight and exactly how much fork oil each one will need. Does it take 10W, 15W, or 20W? I also would really like an exact measurement of how much to pour into my new forks, ml, oz, cups, I don't really care as I've just planned to use an old measuring cup to get it as exact as I can. Thanks to anyone who can help me out.

10wt and a little less than 1/2 liter.

Thank you so much! So pouring in a little under 500ml into my measuring cup will do it? I guess I'll shoot for like 480-490ml.

Did you know there are a couple of posts on fork seals in the tech section?

You will need a piece of PVC pipe with an inner diameter 38mm to drive the new fork seal. You can get it in the plumbing section of almost every ACE or Home Depot
Put a jack under the bike and remove the fr. wheel and fr. fender. Unscrew the top fork caps. Remove one of the forks. Put the cap back and tighten it lightly. Turn the fork upside down and put it into a vise.DO NOT SQUEEZE THE TUBE. Squeeze where the axle goes. Take a long allen socket. Install it in the allen bolt that will be facing up and wack it nice about 10 times/this will loosen the tight threads. If You have an impact driver , use it to take the darn bolt out. Pull the fork from the vise and let it drain in a pan. Pull the dust seal up, using a small screwdriver. Using the same tool pop out the retaining clip that is under the dust seal and holds the fork seal. Grab the Alum. part with one hand and the chrome tube in the other and slide them in opposite direction as many times as it takes to take the assy apart. Slide the old seal out. Install the assy back. Using the PVC pipe install the big washer that is under the seal. After the metal washer is installed all the way in, install the new seal the same way /MAKE SURE THE LETTERS AND NUMBERS ARE FACING UP/. Install the retaining clip and the dust seal. Turn the fork upside - down and fill 441 ml /14.9 oz/ thru the bolt hole on the bottom. put the allen bolt back in the hole and tighten it good. Repeat the procedure with the other fork. Have fun !

By the way, before you replace the seal, give Seal Mate a chance. It helped me for several month, probably could've been a permanent fix if I didn't have a fork brace.

-----------------

The valving in these forks is pretty crude. I don't think you will notice much difference between oil weights, but 5wt to 15wt would work fine.

And don't sell ATF short. It works perfectly fine in these types of forks and is/was often specified by manufacturers on motorcycles with lower-end suspension forks.

So I don't necessarily need an impact driver, a simple allen bolt and a rubber mallet should loosen it up enough? Should I just use my drill to undo it when I've loosened it enough?
