Conversion of ball bearing to sealed bearing in a Deore hub

Wheels of Happiness

I have been thinking of converting from ball bearing (as is often with Shimano hubs) to sealed bearing.  They say it is longer lasting, less prone to bearings getting loose, and getting grit, and affected by water causing their early failure.

The sealed bearing number is RS 6000.

The challenge are with the axle.  4 options:

1.  A anew axle with stopper for bearing (that should fit RS 6000

2.  Put nuts inside the old shimano inside as bearing guide and stopper.

3.  Put a tube shim inside;

4.  Do nothing with the axle.  Just hand tighten the outside cones.

What do you think?   Choose 1 or 4.

I have taken great interest in the following:

1.  Converting from ball bearings to sealed bearing.  I have Shimano hub  which is a candidate.  This involves. removing the cup by hammering this off.   Removing the bearings, and then pressing the bearing at the non drive side.    (Press fit or gentle tap).  Then measuring on the drive side.    And then putting the axle and the bearing.  Tap    Then reinstalling the nuts.  The bearing could be 6000 RS, or 6902 (depending on the hub diameter, and axle OD

2.  The manitou fork.   My manitou fork and the one that was shown by YT (in Spanish) are the same,

     Steps:

    1.  Remove the wheel

    2.  Remove the brakes for the fork

    3.  Remove the bottom fasteners.  

        1.  For the right (spring side with the admustment)  remove the blue adjuster with a 2 mm hex.  Then

             using a 8 mm hex loosen by turning to the right.

        2.  For the left side, loosen the bottom fastener.  using a 12 mm socket or  combination

        3.  Let the oil drip

        4.  You can now  renive tge stanchion

  4.  For the right leg:

      Loosen the plastic yellow stopper using 24 mm open wrench

      1.  Remove the two shafts inside:   Remember the order.   Clean wipe, adn grease the spring

      2  Reattach

 5. For the left leg, 

     Two conflicting versions

    1.  Remove air

    2.  Remove the top cup 

    3.  Clean and regrease

    4.  Remove the sponge and soak in oil

    5  Replace

6.  Inject 10 -15 ml of fork oil (15W)

7.  Replace the 12 mm nut at the left side, tighten the right side using the 8 mm hex by turning to the left.

 8.  Reattach the blue adjuster using 2 mm hex

   

Application of what was learned yesterday: regreasing sealed bearing, (later removal and installation of sealed bearing at the hubs)

Yesterday, I learned from Google (You Tube) on how to:

1.  Regrease sealed bearing (I thought you grease them only at the shaft;

2.  Removal and installation of sealed bearing

We usually bring the bike to the bike shop for these two services

1.  Regreasing the sealed bearing

    With a pick or a sharp pointed cutter, we pry off the rubber cover of the sealed bearing.  Then we see 

     the bearings on their cage.   We can discover that:   they are dry or rusty. 

     I was able to do this with an MTB with sealed bearing. I think the practice can save you money from 

     buying the hard to get bearings, and or prolong their lives. 

     I eliminated the funny noise from the rear hub of MTB and the wheels turn faster and smoother.

 2.   Removal of the sealed bearing

    1. Without tools

         1.  You can use a flat head screw driver to dislodge the bearing from the hub.   Be careful

               not to scratch the inside of the hub; as you would have difficulty in reinstallation.

              or use a drift if the shaft/axle using a rubber mallet.   Attach a nut on the axle shaft so as

              to destroy the threads.

       2.  Reinstallation

            Use the old bearing as a drift to reinstall the bearing.   Use the rubber mallet again to drive

            the bearing again

   2.  With tools

        1.   For novatec, there are special tools.   There is a bolt with expander that you grasp the 

              the inside of the bearing hub.  Then to remove, as in the crankset puller, you turn the upper

              portion so that the puller extracts the bearing from the hub.

       2.  Or use steel round bar with endless threads (about 14 to 18 cm)   At the end are large washers 

             that can grab the  diameter of the bearing.    You pull from the other side by turn a butterfly 

             nut or ordinary nut to pull, dislodge the bearing

      3.  Reinstallation is the reverse of removal.
