    DU anti-friction ring

    Hey.
    Im getting ready to rebuild my front forks because I have a leaking oil seal. I bought the oil and dust seal but upon reading the Clymer manual, I find that I would have to change the upper and lower DU anti-friction rings. Given that they are more expensive, Is it really necessary to change them? Its just that im supposed to do the job with a friend next sunday and Im not sure if the parts will come in time from the dealer.

    Upper ring:51152-45400
    Lower ring: 51121-45400

      Oh thanks, its just that I have a friend who is a mecanic that is coming to help me do the job and I didn't want to postpone the job to wait for the parts since the season is starting!

        What the heck is a DU ring?


        Anyway, unless a lot of crap has gotten past the seals into the fork, and/or the bike has done a LOT of miles, the teflon coating on these bushings generally lasts quite a long time. I've seen them in fine shape at 80,000 - 100,000 miles.

        The upper ones see more stress and wear faster.
