Where's a good source for the internal plastic sleave/ bushing? My wife and I have a matched pair of MTBs with these forks. They're well overdue for their first disassembly and clean. Although not in horrendous condition I'm anticipating that new sleeves would reduce the amount of fore/aft cocking. I feel more enthusiastic about taking these apart and cleaning them up after seeing your clear presentation of disassembly and re-assembly. I learned my bike maintenance skills in a previous era of 5 speed derailleurs, and brake pads that grabbed the rim of 27" wheels. Suspension forks weren't a thing back then. Thank you for being complete but editing out the tedium.

@bryanjohnson665 2 жыл бұрын

Well done video and very informative. Unrelated to the video content and quality is the fork itself. I have this fork on my daughter's 2019 Trek Marlin 5 and unless you are riding on a sidewalks, streets, prepared limestone or a smooth dirt trail, the fork is pretty much useless on bumps, small rocks or tree roots and a rigid fork would be better. While the Marlin 5 is an entry level, dare I say, mountain bike, the fork holds it back. My thought is once you remove the fork for service, just toss it in the garbage and upgrade to an air fork if you are venturing into any real mountain bike trails.

@Jamesthebikeguy 2 жыл бұрын

That's fair. I serviced this in preparation to build up a 2015 Marlin 5 that this came off of. It is a perfectly useable fork, but is the weak link in the Marlin 5 being a decent MTB. With parts availability so tough right now, options for a replacement fork are slim. I think the Rockshox Judy would be a nice option, or actually I have a want for the SR Suntour Epixon air fork. Either of those would turn out nicely.

Mine is kind of like this. Except there is a damper cartridge in one side (with a bunch of air in it so the lockout does not work, not sure it ever did work). And the other side is where the spring is (which some how is a half inch shorter than the cartridge side and does not move (making the fork rigid). Any tips on how to get the spring out and getting it to move again? I will try to get it out of the top like in this video and well see what happens. but please comment if you have any tips for the lock out version of this fork.

Pretty typical on most forks. In fact high end forks one side is spring and the other is damping. In this case the damping is purely done via grease and friction so nothing is needed in the other side.

Suntour M3030 is quite a basic fork, I'm trying to think what bikes come with those, maybe low end hybrid bikes or super cheap ebikes. I think the Suntour XC range are generally ok but I'm sort of thinking the Suntour M3030 is more akin to a Zoom fork in performance.

Coil suspension is linear so if you take some length off the spring it will be just as firm but there will be less travel, dropping the front end of the bike down. The only thing you can do would be to find a softer spring which would be very difficult. A service if the fork is a bit older to free everything up or a new better air fork.
