Crank bolt /cap keep getting loose

Wheels of Happiness

After this post cleaned the crank axle of MTB, regreased this, the crank bolt cap, m20 kept getting loose.   Although this post followed to tighten the pinch bolt well first, tight, the end cap get loose.   I tried putting teflon on the thread.  But still the same.

I have to tighten the same after every ride?

When you disassemble your crank, be sure to watch your FD adjustment

This post always neglect this and after a crank disassembly, the FD could not shift the fd to the large chain ring  More specifically the crank has not been tightened well or got loose when this post used the bike.  All this post had to do were:   1.  tightened the crank bolt,   2,  loosened the high adjustment screw of the FD adjustment screw.  

It seems that with Campy super torque crank has this common problem.  It does not fit most of the BB and there seems to be about 1 mm of play - hence the need for wave washer.  But still there seems to be some side to side movement that is why sometimes the chain falls off.   The video maker recommends using loctite to fix the crank.

Its all very detailed and all complicated that is why many just let their mechanic do the job;   pay them well and let the mechanic do the worrying.    That is why I had to bring the 10 mm hex  crank bolt tightening too.  

Lost crank bolt replaced - problem solved

I lost the crank bolt of my Fuji last Friday, almost noon time about 3 km from Holy Gardens, at Lingsat San Fernando La Union. I must have dropped it some 5 km away at Bauang because I heard something loud dropped. I did not stop because some Recyclists would be crashing at my back

The left crank arm dropped beneath my feet;  and could not continue.  I loaded the bike unto the support vehicle driven by Jonjon (Widltrak Ranger owned by Sympathy Angono) and just led the bikers to Holy Gardens La Union for lunch and refreshments.

I was saddened by the loss because I would not be able to continue the once in a lifetime ride. It was kind enough for Vhen Apran to lend me his bike:   a Sintesi with AmCla wheel set.  8 speed Sora.

I was sad too because I may not be able to buy  replacement:  maybe a new BB,or a new crankset.

So I met Sec Noe this morning this AM and told me to be positive that I would find a replacement at Nuts and Bolts in Tayuman or at Eduard. And true enough I found one at Villamayor c/o Jay.  It cost P20.00. I bought 2.   The other crank bolt, at the drive (ring) side was also loose.  How come they would get loose -sa lakas at bilis ng padyak?

Problem solved. Hay salamat

                                            Napalitan na -  solution P20.00 at Villamayor bike parts
