    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Oil Seals won't seat

I have an '82 550M, and I am in the process of replacing the oil seals. I have two problems.

#1--Which way is up? One side is completely flush, the other has a ridge slightly higher all the way around.

#2--I can't get the seal to seat inside the outer tube all the way. It won't go down far enough to get the washer and the snap ring in the slot. I've tried it both ways (whichever is right-side-up).

I've replaced the upper bushing/slider ring, the spacer, and the seal with new OEM parts, so they should be OK. I just can't get the new one down in all the way.

Any suggestions?? Thanks!!
 
The side of the seal where you can see the little spring running the circumference of the seal should be facing up (the flush side facing down).

You made need a little pressure to get the seal to set properly. I always found that a piece on PVC pipe that is big enough to fit around the fork tube but with an outside diameter small enough to press on the seal and not bind on the fork slider to be an ideal seal driver. The pipe will have to be longer than your fork tubes, but just a few extra inches is long enough.
Just install all the pieces as they should be, then place the pipe down over the seal and tap evenly with a hammer until everthing is in it's proper place.

According to your description I installed my seals wrong. I have to flush side up on my GS750E, that's the way they were originally installed and they don't leak so I assume they are right.

You DID install them correctly. If you can see the spring they are installed incorrectly. The installation instructions are good, but the flush side faces out.
 
I use the old seal (perfect size) and a screwdriver/hammer to press the new one in.
