New Learnings from my adventure with bearings

Wheels of Happiness

As this post tries to study and repair bearings, many things have been learned:

1.   Headsets and bbs are expensive.  However, bearings for headset can be bought cheaply.

                Head set cost P500- 700.  However, bearings will set you back by P70.00 each x 2 =  

                               P140.00.  That is 1/5 to 1/6 of the whole headset 

                BB say for shimano cost P700.00.  However 6805 bearing may be had for only P46.00 each

2.   Bearings can be re bearing.  Its balls can be replaced giving it a better life.   Bearings that are small

               can be bought from Sising.  A pack of more than 100+ cost only P30.00

              Steps for rebearing:

               1.  Remove the Rubber seals front and back

               2.  Push the plastic bearing cage from the front, and the back will fall off

               3.  Do this on a table with the towel.  The bearings will fall off and scatter

               4.  Soak the bearing and the races in degreaser.  Clean  (Servicing the bearing at the bike -

                     crank, headset or wheel set does not clean the bearing thoroughly.  

               5.  You can use the same bearing or use the new one from Sising.    According to the YT

                     source you can do this five times at least

               6.  To reconstruct, place the bearings:  14 first on the outer race.  Then insert the inner race

                     and then wiggle in the 15th.   Make the distance between the inner and outer equidistant

                     and then try to get the other bearings to the top.  That will lock the inner and outer race

               7.  Patiently try to get the bearings inside the designated cages

               8.  Lube the berarings:  oil and light grease

               9l  Replace the RS seals

               10.  reinstall at the BB or head set

               REBEARING is even cheaper.  Because you can recycle old bearings again and again

               A pack of 150 small bearings will set you back by P30.00 and you can replace  6 bearings

               You can still reuse old ball bearings

  3. After having done 2, you learn that bearings are fragile and can be destroyed by wacking or 

      hammering

  4.  Bearings easily get fouled up especially the BB and head set.   Servicing them requires 

        closer interval

  5  The two problems with bearings are:   removal and press (reinstallation)

  6.  Many mechanics and bike owners prefer to use hammer and a drift especially for hubs

       The removal tools involve pushing out (for BB) and pulling (using pullers) and or tools

        that expand within the ID of the inner race.   

       Variants include:

       1.  Steel made toks

       2    Attachments that expand with split bolt that expand within the inner race when the inner

              bolt is drive down

       3.   Cylinder cut diagonally that expand when pulled by another bolt

  7.  Press fit

       Require a threaded rod and two nuts.  The drift for the bearing could be a washer, another bearing

       or brass attachment for hoses.   Maybe you should buy the commercial drifts:  for 24 mm, and 

       30 mm for BB, and for head sets :  31 to 52 mm

  8.  A whole set of pushers and press fit can set you back by P1,500 for ZTTO.  However I saw 

       a Lazada post featured a ZTTO set for only P500+ 

  9.   The easiest cheapest way to service bearings especially for hub bearings is via tapping with a drift:

        1  Removal:    For front wheel Using a cup or two pieces of wood, put the wheel hub on this and                                     lightly tap the axle   The other bearing will fall of.  Tap lightly hit accurately and

                               be careful not to nick the hub.

                              You can remove the other bearing tapping round round the bearing

                              For the free  hub:  If there is a stopper, push the tube slightly to one side to access the

                                                    the bearing.  When you have removed the stopper you can easily tap

                                                    out the other bearing

                              For the wheel hub:   Use an old shimano axle use the nut to push against the bearing

                                                   and tap.

         2.  Press fit by tapping:

                            Use a size 22 or 24 socket wrench or same bearing to tap in the new bearing

                            Sand paper the drift bearing so that it may not get stuck with the new bearing

                            Only taps not hammer

  10.   Wheel bearings are usually:  6000, 6001, 60100, 6802, 6902.

                                                         6806  if for BB30, 386, 

                                                         RS refers to rubber seal.  RS 2 means RS for both sides  1 RS 

                                                         is better

                                                         ZZ bearings are sturdier have steel seals.  However they are

                                                          not serviceable and not very efficient.  

                                                          6805 if for Shimano, campy cranks

  11.  The biggest enemy of bearings is moisture and rusting.   Thus, it is essential not to water 

          your bike, ride it during rains, or through flooded streets or streams.   Be sure to  disassemble

          clean and dry when you do.

                              

   

Riding the Bianchi road bike again after two months of MTB rides

We commemorate two events today:   99th birthday of late Ferdinand Marcos and the crashing of 4 passenger jetliners piloted by suicide pilots at NYC Trade Center, Pentagon and  Pennsylvania where 3,000 Americans perished.

Yesterday I rode solo to Pililla on my Bianchi roadie After saying little prayer at Sacred Heart Parish in Tayuman (which we usually do for to praise, thank the Lord and guide us in our biking so that we arrive home safely) I tried to chase some MTB which I did so successfully.  There was one in blue jersey who also chased me again.  The last time he did that was at Island Gas and then never saw him again.   Then I chased somebody at Callahan, but I never got past him when he overtook a long truck going down from Callahan.  I was able to pass him and another MTB who was in pink and black jersey.   He passed me at Morong market, but I retook the lead at Namay.   I was solo again up to km 55 where a large thighed rider on a roadie with back pack passed me.  I chased him and road by him side by side until km 58 which I planned as the limit of my ride.

On the way back after seeing that there was no food in Tanay Gardens, I gave chase to two riders one tall and one short and caught up with them on the way up the hill at the Baras Tanay boundary and overtook them.  They caught up with me again and chased them until past the PNP station and towed them until Maybancal where I peeled off to look for lugaw.

In Angono, I saw the group of MTB riders (group of Armin).  They said they toured from Antipolo Teresa., Morong, Cardona, Binangonan and home. They recognized me on my roadie and said hello

The heat was overbearing yesterday

Thanks for the moral support from fellow Recyclists in today PNP sponsored race

                               Many of the Recyclists were in this area of the diversion

I heard them and saw only a few of them while focusing on the task at hand - to finish the 4 loops of the rather challenging Binangonan - Cardona loop. -   Montevideo, Callahan, Diversion, LLDA.   I saw Meong, Jess, Jeff, Vhen, Sec Noe, Armin, Val,  and Master. Sec Noe who texted me na manonood lang, gave me a dousing of water and Cobra drink.  Special thanks to Pres. Luis for informing the other Recyclists about this event and dragging them to the race route.

Thank you.  Your presence gave us more courage and determination to finish the race which was our only goal and to beat other riders.    Well we achieved them (Tito and I).   We completed the four loops, and a good half of the field especially members of the command, did not finish the course. (race)

Tito suggested the following:

1.  That we strengthen our Recyclists;  that we demand certain commitment and loyalty to Recyclist.  NOT EASY COME EASY GO. That we have more meetings and motivation

2.  That we join more races, and that we are properly represented by the group, rather than by individuals (Papa Ric is in many races collecting bounty for being the oldest)

3. That we give full support to the participant, like bike, or MC and other logistic support.  Mambog Biking Club, he said has enviable support for its team mate who joined this race.
