Yamaha YTM Front Shock Disassembly How-To

[El Camexican]

Wow!, as usual Primo work.

That trike is good looking.

I know! Can you believe some guy on another thread wants me to cut it up and put a swing-arm on it!

You guys do nice work. Stick a fork on it, it's done.

You are totally correct the forking around is over,,,, and now to Brembo disc brakes front & rear to match that WP shock.

If anyone has rust on any parts, one way to remove it is to buy some powdered/crystal 99% Oxalic acid and a plastic tub . Mix 1/2 lb of acid per 1 gallon of watter and let them soak until they are clean . This take from 1 to 4 days depending on the amount of rust . Mixing it at 1 lb per 1 gallon of water will speed the process up.

Do this in a well ventilated area and do NOT breath the dry powder or the fumes from the mix . It is similar to battery acid in that it can make your hands sting slightly and burn holes in your clothes . If you get some on you simply rinse it off . The mix can be neutralized by adding around 1/8 cup of baking soda per gallon of mix at which point you could even drink it if you wanted . If you have a pool test kit, neutralize it to 7.5 - 8.0 ph . After this you can dump it in the yard but the rust can leave stains.

Man, 10 years later I'm pulling some YTM 200 forks apart wondering how I get the stupid seal out and remember I posted a how-to... I'm learning from younger me! I think I still have that homemade press in the shed someplace, time to dig it up!

On the 200 just remove the cap, spring and dump the oil. Then remove the retainer clip and washer above the seal. Lock the lower leg in a vice and use the upper tube like a slide to pop the seal out.

If it won’t come come out use a heat gun to soften the seal and expand the lower tube and try again. I’ve had to use a torch on occasion, they can really be stuck in there at times.

Be ready for it to let go in grand style when it does and make sure you don’t end up tossing the upper tube through a window or spearing your dog.

The heat gun is a good idea. One shock is a little stiff (it must be slightly bent) so the slide method won't be easy.

Wow, one of mine was really bent and it didn’t bind, so yours must be pretty bad. They usually bend just below the lower clamp, so short strokes should still be possible.

this will be usefull for my 3 200 that need attention!
