Title: Yamaha Ag 100 rear shock overhaul
Post by: Haysie on August 10, 2015, 05:38:07 pm
Hi guys,

I have been restoring a 1973 AG 100 and having trouble with the completely removing the rear shock parts. I can remove the top plate and spring but can't remove the bottom plate and height adjuster. I am thinking that the top mounting bolts on to the shock stem. Any tricks to removing the top mount? I have a 1973 Lt100 and it is a different shock altogether.

Might be cheaper in the long run

Are you sure that the eye screws onto the shaft? Some of the OEM shocks have the eyes welded to the shafts and you can not remove them.

Thanks. Yes I have been looking at replacements as well and it might be cheaper dealing with it that way.

Had a closer look and it doesn't look welded, but it certainly won't budge! I put the shaft in the vice and locked it down good, still won't budge. Looks like new shocks.

If they are welded you wont necessarily see a 'weld bead'. They are often resistance welded together and it will just look liek 2 parts butt joined together. Even if they are screwed on they will usually have high strength threadlocker and will require a fair bit of heat as well as soft alloy clamps the correct size of the shaft to grip the shaft in a vise. If you can post photo of it then someone may be able to help you more with what you have, if not not take them to a shop or buy some new ones. I would be surprised if an AG100 had rebuildable/serviceable shocks.

Thanks for the link. I might look into getting some of these for my DT125. Don't you hate it when postage costs more than the product?!  :o
