Thanks for your video. note: light heat to outside of fork housing with a butane torch "unglues" the seal from the fork tubes and expands the aluminum a little making removal of seals a bit easier.
This is a good tip. Thanks. Also heat to release any thread lock or rust seizing the Allen key at bottom of the tube. Heat is a mechanics friend when used wisely.
Outstanding, the first vid I found that didn't show you needing to remove a snap ring before you separate the tubes first. I've been at my forks for hours trying to get a snap ring out....but I couldn't see a start or end of one from the top. This saved me, cheers
I took a grinder to the end of a pry bar and shaped it to the size of the inside of the fork tube. Pops the seal out perfectly without scratching the tube. Good video easy to understand.
Great video I did the forks on my 75 dt250 exactly how you did yours and installed them and the front wheel on the bike yet the forks will not compress at all? Any suggestions?
Thanks for the explanation. I had a Yamaha just like this one, same color and everything. Stolen from me in Walla Walla, Washington, with Alaska license plates. Now I have a 1982 Yamaha XT200 (12,000 miles) with the same forks. I'm replacing the seals.
Not sure but it looks like you put the fork seal in upside down.? usually the solid top of the fork seal is on top. Look at 6:57 and see what you think? usually they say the lips of the seal go towards the oil. Sorry if this offends anyone.
Great video guys, Helped me a lot, Hi guys I have a YZ80S. My shocks are the same as you by the sounds of it & after seeing your reply's below I used a tapered bar of alloy & it held it in place through the top to allow me to loosen it. I have removed the center section now, BUT the shock long tube does not come out & appears to be still stuck on the bottom. Did you have trouble with rust build up stopping the tube from coming out completely Tricky
I just opened my forks from my 1982 XT200 and the bottom hex screw is a bit different. Outwardly the forks appear the same, except you bottom hex screw is recessed a bit more than mine. According to a service manual that I found online for a Yamaha GA200 that has the same forks as mine I need a special T-Handle tool to keep the Damper Rod from turning. Otherwise when you turn the hex screw at the bottom you never accomplish anything. It just turns around without loosening anything.
Hi Lance thank you for the reply as it helped me heaps with my YZ80S. My shocks are the same as you by the sounds of it & after seeing your reply I used a tapered bar of alloy & it held it in place to allow me to loosen it. I have removed the center section now, BUT the shock long tube does not come out & appears to be still stuck on the bottom. Did you have trouble with rust build up stopping the tube from coming out completly Thanks mate Tricky
Note, attempting to remove a fork caps without loosening the upper fork clamp will result in a ruined fork cap (if the clamp squeezes the threaded portion of the cap). With the caps off, oil can be drained without removing the little drain screw, simply invert the forks. Amazed that the damper rod didn't spin when the allen bolt was removed from the bottom (by hand no less!!), typically you'll need to ram something from the top, I use a broomstick, to keep the damper while using a power tool to spin the allen bolt. Removing the seal would be a hell of a lot easier by applying some heat to the slider around the perimeter of the seal, also makes installing the new seals a snap (apply silicone grease around edge of seal to make it even easier).
Just one nit-pick that is 99% not a phillips head but a JIS and if you use a Phillips and it's stuck you WILL damage it, for lose screws phillips will work, but for tough ones, do use the board equipment or other JIS bits.
No it IS necessary if that damn 8mm allen just spins in place!! Not one of these DIY video's on here address the use of that damn tool. 99% of us out here encounter this problem and I am dealing with it right now on my 76 IT400. Total bullshit. These guys that think they know how to do forks obviously have not encounter this all to common issue so they don't bother to talk about it.
@@SwormCycles If you can , after you remove the front axle use an 8mm hex in an air impact to break loose and "out run" the damper rods. A cordless should work too. Loosen upper triple clamp before breaking loose the cap or if necessary slide the tube up a few inches and re clamp the tube to hold in place. Use a torch to heat sliders for expansion purposes. A heat gun on hi works too. Makes it much easier to get the seals out.
Yeah there’s a few vids showing nuts welded to end of a rod. Trick is to find the right size nut to fit the Allen key at bottom of inside fork tube. I’m paranoid of stripping anything. So I’m leaning towards buying an Allen key socket set and long extension.
