Default TIP - MAKE SHIFT - FORK SEAL DRIVER

     

Hi, I just replaced my fork seals and found an easy way to drive the new seal all the way in using the inner tube as a slide hammer and the old seal as a spacer. I done away the need for the Yamaha fork seal driver by making a small mod to the old seal. Hope this helps someone out there and worked a treat on my 2000 YZ250.


After you have remove your old fork seal pull the inner and outer springs of it. Put the seal sitting low in a vice and cut straight through it with a hacksaw. Be careful not to bend it or distort it too much.

Turn the seal over with the last cut sitting at the lowest point and place it low in the vice again.

Cut only partly through this side of the seal using a gentle motion until the blade starts to get caught and is hard to keep the blade moving easily. At this point stop and you will notice that you have cut through the outer metal part of the seal but it is held together still by a thinner part of metal of the seal.

Put the springs back on the seal.

As you follow the proceedure to put the fork back together put the dust seal on the inner tube first followed by the new seal driver tool you just made and then the new seal. carry on replacing all components and slide the inner tube in to the outer. Turn the fork upside down on the floor sitting on a piece of wood so the outer tube doesnt get damaged and gently drive the new seal in by sliding/hammering the inner tube using the reverse manner to which you got it out.After the seal is in far enough to be able to put the clip back in you can remove the tool.

T remove just "Twist" the old seal and the springs will pop off and you can remove the seal from the inner tube. Cut the springs off with a pair of side cutters. Push the dust seal in place and Bob's your uncle!

Hope this helps
