Looking for Look CX-7 parts and tech info

John Rees

I have a pair of CX-7 pedals that are making some scraping noises.
I took them off, opened them up and cleaned and re-greased the bearings.
I could not figure out how to remove the needle bearings in the end of the
spindle.
Alas, still making the noises, so I'd like to try to replace the bearings.

Where can I get parts for these pedals, and more importantly, where can I
get service information. I have the original paperwork for the pedals, but
they are not detailed enough.

I am looking for the kind of diagrams Shimano makes for their parts.

Hi John -

I'm currently "down" on Look pedals. I have three pair of them.

The oldest are the first pair of clipless pedals I ever had and are some 10
or 12 years old; and the newest are A3.1 Looks. I really like riding them,
but servicing them seems an excersize in futility.

First off, how did you get them apart? I cannot find a tool to fit the
retainer that holds the spindle in. I was able to get one A3.1 pedal
disassembled using a PVC connector that fit snugly over the retainer. The
retainer was not in so tight that it would not come out by hand. The other
pedal just wouldn't budge. My complaint was that the pedal was making a
scraping/clicking noise as yours was. Wouldn't you know it? The pedal I
could get apart was not the one making noise.

Once I got the spindle out I found that I could neither get the needle
bearings out, nor could I get the sealed bearing off of the spindle. It is
pressed in place. There is a soft clip that prevents that bearing from
coming off should it work loose, but it does not retain the bearing per se.

This led me to try and dissasemble my other pedals. My oldest pair have a
cap at the opposite end which, when removed, shows a nylock nut on the end
of the spindle. Fine, just remove that and service the pedal. Wrong, it's
heavily staked in place. Something would surely get wrecked trying to remove
it.

On the newer pedals it looked to me like you would need to have a specific
bearing puller to grab the far side of the needle bearing cage and pull it
out. I did not try modestly heating the pedal body and attempting to draw it
out with any of the tools that I have that might have been pressed into such
service. I merely filled the pedal body with grease and put it back
together.

My impression, looking at the three pedal sets that I have, is that Look has
a "not user serviceable" approach to their products. Seems a pity for pedals
that sell for as much as Looks do. Shimano gives you a tool with your pedals
so that you can take them appart and service them. At least they used to -
haven't bought any Shimano pedals in a few years. Next time I'm in need of
road pedals I'll likely be looking at Shimanos....

Regards,

Tom
