Suntour XCT Fork Service - Disassemble/Clean/Lube/Re-assemble

Рет қаралды 265,606

5 жыл бұрын

I show how to tear down, clean, lubricate and rebuild Suntour XCT (SF8-XCT-V2) forks/shocks. Periodic maintenance will help prolong the life of the fork and maintain performance. Basic service to keep your suspension working and from becoming stiff or frozen. This bike is a Raleigh Mojave 4.0. The XCT fork models have varied over the years. I believe this fork is a SF8-XCT-V2 from 2008.
* Use grease made for forks. I use Slickoleum which is also sold under the name Slick Honey. You can also use SRAM Butter or Judy Butter. If the fork uses oil, use the proper fork oil. Use of a grease/oil not made specifically for forks can damage the plastic/polyurethane parts, or otherwise leave the fork not working properly.

My forks were a little different but I figured it out with the video. I didn't have the extender needed to get a 5mm hex wrench down the fork tube but it turned out that I didn't need to completely disassemble the forks, I was able to slid the forks out to full extension, apply grease, reassemble and everything works now.

I answer myself for future reference :). If you run into this problem extend the fork as far as possible and than you can unscrew the bottom bolt because it wont turn easy any more (you use the pull pressure to hold the counter part). No need for extender.

FYI some of the Suntour XCT forks on the slightly beefier mountain bikes have two springs, and the bolts inside the forks require a 5mm hex socket - the 12mm normal socket will not work because the bolts have a rounded head.

I'm not sure what you need on something like that though or what they actually include on those pegs or whatever they call them.
