is there a guide anywhere on how to do so? one pedal is spinning much more than the other, wouldnt mind giving them a regrease etc if its at all possible
any ideas where to start, or videos would be appreicated!
Undo the locking collar that holds the pedal body onto the axle. Check the cone and locknut at the end of the axle aren't undoing themselves. Then fire a load of grease into the pedal body, tighten the locking collar back up, all the crappy grease etc is force out of the pedal.
One side has a left hand thread so just be careful which way you turn the collar.
You dont even have to remove the pedal from the crank.
Cheers bigyinn - they dont feel rough bearing wise (spinning the pedal) at least, i expect they just need greasing, i think the xtr trail pedals has a tighten sign on the gold bit so you can really go wrong with undoing them etc
will have a go at that then cheers, do you know what size spanner for undoing that locking collar?
Just an imperial adjustable spanner and you'll be reet.
There are some great [url= http://techdocs.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/PD/EV-PD-M985-3070A_v1_m56577569830820610.pdf ]tech docs[/url] on the Shimano website that shows you what to expect when you pull them apart. Two adjustable spanners and you're good to go.
I haven't done Trails but have pulled apart the Race's. They use similar bearings and layout. Main thing is to make sure you don't lose any ball bearings! Also a bit of a PITA to keep all the loose balls in place as you put it together. Nothing major, just something to be aware of. I got a whole bag of replacement ball bearing for just a few pounds on ebay and replaced them as I was regreasing as some play/ roughness had developed. Only other thing is that tightening up the two locking nuts on the end of the axle was a bit trial and error to get spot on.
If the bearings aren't rough then don't touch them!
The fresh grease you put in the pedal body purges the old grease out of the bearings when you tighten the collar.
Does it have to be an imperial adjustable or would a metric one work? 😉
US or British Imperial?
Damn…i only have a whitworth adjustable
Should do at a push, shim it to make up the difference? 😆
Ok that was relatively easy and pain free
Was cool watching it purge all the old grease out of the pedals I must say! Bearings actually felt smooth too so just some new grease purged through and all gravy again
The only slight issue I had a few times when tightening up the gold collar the pressure and slippy ness pushed the seal out on the axle, but after a few attempts and getting it less slippy and pushing it in whilst tightening it got there in the end, both pedals now spin about the same resistance back on the bike where as before one was spinning really fast!
So cheers for the hints and tips worked a treat!
What spanner did you use?
Myself 😉
Seriously though not sure just grabbed a load till one fit 😆
Glad it worked well. Yes the rubber seal gets forced out, but you can normally just poke it back in.
cheers bigyinn, yep just popped them back in, think the seals just become majorly slippy from the new grease and pop out, everytime you get right near to the tightening point! but got there in the end, very easy job, and the amount of terrible brown/grey grease that came out was a fair amount, so definitely worth doing
