    Hi,
    I'm failing at replacing the front wheel bearings on my 1982 Seca 550. Any advice would be appreciated.

    I'm using the wheel bearing kit from All Balls Racing, 25-1311. Has anyone used this kit?
    https://www.allballsracing.com/25-1311.html

    I've replaced the bearings twice and each time I end up with the bearings froze. Both times I took great care to not hit the inner race. I'm using a nut and the old bearings to drive the bearings into the hub. I was careful to protect the inner race but maybe...

    The first time the inner spacer was misaligned and I had trouble installing the wheel. I thought I damaged the inner race during installation. I do not recall checking if the inner race was moving freely before trying to install the wheel.

    I ordered a new kit and tried again. This time I made sure the spacer was aligned. After installing the bearing, the inner race was froze. I installed both bearing before checking that the inner race moved freely, my bad.

    Both times I did pull the seals on the bearings and clean out the grease and repack with red grease.

    Am I using the wrong kit? Is there a better kit? I don't want to do this again. Any advice?

    FYI, I'm new to working on anything mechanical.

    You are probably driving the bearing in too far. The first bearing gets seated fully, the second one you tap in until it just touches the spacer. If you drive it in too far/hard it will put pressure on the inner races and cause them to bind.

    Xj4ever has the correct bearings, when I did replace mine these were spot on. I have used All Balls seal kits they fit good ,but the bearings perhaps might be off slightly . Chacal might be slightly higher in price , but his parts are great and if you have any problem he makes it right.

    I have used those kits work fine.
    make sure you install spacer in correct direction it has a flange washer on it flange should be on speedo hub side.

    1 put your bearings in the feezer for a few days
    2 go buy a socket is as large as the outer race
    3 get wheel ready a little spray silicon on it
    4 take 1 bearing out of the freezer use a can of air upside down and spray down the bearing
    5 gently tap it into palce if you froze it enough you may be able to push it in most of the way . wear gloves.
    6 repete chilling for second bearing
    7 put axle through second bearing aline spacer with axle , you will need a hole in bench for axle to drop through
    8 tap it into wheel

    this is how to do rear read it

    Hi All,
    Thanks for the replies.

    I will re-read the bearing install information.

    It looks like may have over driven the bearing an caused the problem. When I removed the bearings after the 1st install, the flange washer as broken. I should have mentioned in my original post. This might be a clue as to what I did wrong.

    Should the flange washer be pressed fit onto the spacer? Should I put the bearing, spacer and washer onto the axle and install (do not press fit flange washer)? Or press the flange washer onto the spacer and then put the bearing spacer/washer onto the axle and install? The 2nd time I installed the bearings I pressed the flange washer onto the spacer.

    When I dissembled the wheel the washer was pressed onto the spacer. Originally I did not replace the flange washer.

    I am freezing the bearings before assembly.

    I'm ordering new parts and trying again.

    Thanks for all the comments! Hopefully I get it right next time...

    the flange presses onto the spacer it is there so the spacer does not drop when axle is pulled or installed. it keeps 1 end up far enough to lift into position

    install 1 bearing the thread the axle through . it is just to keep spacer alined so it does not cock on you and push against the inner bearing.

    lightly tap bearing into place you will hear a different sound when it has bottomed out
