MT220 Fork Boots
« on: April 25, 2015, 12:23:06 PM »
I just picked up a 2012 Trek MT220 24" for my son, and the rubber fork seals/boots/wipers (not sure what they are called, and they seem to serve all three purposes) have come loose and are no longer attached to the fork stanchions.  It doesn't seem like it will be possible to push them back into place with the fork rubes in place.  However, I'm not sure how to disassemble these forks.  The bottoms of the fork legs are tapered to the drop-outs, with no screw in the bottom of the fork leg for disassembly.  I can get some pics if it will help.  In the mean time, here is a stock photo of the bike so you can see the forks:

In summary, how do I put the fork seals back in?  Disassemble?  How would I do that?  Thanks for the help.

Dont worry about them. Keep the stanchions wiped down and clean, also around the seals.. You could put some Slick Honey on stanchions and compress fork to work it in every so often. Wipe off after applying. Buy a new one after this one is toast.

I've had my wiper seals unseat partially and made use of something I had laying around to press them back in. You may need to look around and see what you have that is somewhat flexible and strong that can be modified to do the job. If PVC was thin and flexible enough you could make a short section act as a press by cutting out about 45-60 degrees of the diameter then gently pop it around the stanchion and press down on the seals.

You don't want to put much pressure on anything that contacts the stanchions to prevent scratching but some plastics are smooth enough to not cause damage. You'll want to put a bit of lube around the circumference of the wipers and the top of the stanchions to help them pop into place.

Maybe the plastic retainer "tube" that comes with a new cassette could be made to work, depending on the diameter of your stanchions. Or a film canister, a pill/vitamin bottle, etc. I'm sure you'll find something that can be rigged into a tool for the job.

Good luck!

That fork on the MT220 is surprisingly cheap on eBay.  I needed one a couple years ago, do not remember the price  but remember being amazed at the low price.
