Cleaning and regreasing of Campy crank

Wheels of Happiness

I met Mario Toledo, my best mechanic,  yesterday at a mountain trail road and hastily I consulted the campy crank, (the bearing of which was just replaced)  which has not be been rotating smoothly.  He advised that I should disassemble, clean, and regrease.

Which I did today.  Removal of the 10mm crank bolt (and reinstalling is a challenge).

True enough the crank axle is dirty and the non drive bearing is a little bit sticky.  So I cleaned the crank axle the bearing, and the crank shell. Generously regreased the bearing and the axle with synthetic lighter grease.   How could they all be so grimy after just three months?   Its good that the bearings were still in good shape.

Now the crank now turn faster and smoother.  I must have lost 10-15 watts with the dirty 

Regreasing, rebearing head set bearings resulting in better bike handling

I have not serviced the bearings of headset of MTB.  Merely cleaned them and placed grease underneath the seals   Not knowing how to disassemble I dared not.

After reading a lot, I dared disassemble the bearings of the MTB.  They are PO3   41 mm, and P16  52 mm.  I had to tap out the bearings with a screwdriver.  The 51mm scattered and they were my difficulties later. I could not get it back properly.

I followed the directed processes:  I soaked the bearings with the plastic guard in detergents to remove the sediments.  For the bottom bearing, I had to replace  about 10 of them (from Sising inventory) because they fell off as I was returning them.

What a difference this PMS did to the bike.  The steering was lighter and the bike handled better   

Only servicing of the suspension cartridge and  truing are the unlearned skills remaining.   

I could probably run my own workshop. soon and give some mechanics a run for their money.
