Shimano M324 SPDs maintenance

Postby westview » 16 Oct 2018, 9:35pm

Hello folks
just completed my first few days commuting with SPDs and despite being a bit nervy, i have found them to be pretty good with a pair of Northwave shoes. i currently ride a 29er MTB (there, i said it!) 9 miles each way.
Anyway, i like to keep my kit clean and well maintained. Any tips for keeping the pedals in good order during the upcoming gritty, grimey winter months? ideally i'd like the pedals to be shining like new this time next year! they are replacing a pair of DMR V12s so have a lot to live up to.

Aside from a wipe down from time to time, oil the spring mechanism for the clips. Very little you can do with them otherwise. The tool you need to re-fit the bearings is £70 so cheaper to buy new ones.
FWIW I use the same on my commuter all year round, they are 11,500 miles old now with no issues.

thanks Cosmicbike, sounds like they are low maintenance which is good. judging by your mileage, you'll know how - especially the winter- road conditions can gnaw away at your bike.

you can spray a water displacer/lube over the bindings every week. You can also pull the seals away from the pedal body and squirt aerosol motorcycle chain grease into the inboard bearings. You can pry off the dustcap and lube the outer bearing.

However past that you need to obtain the (expensive) shimano tool for adjusting the (cup and cone) bearings. To get to the bearings you need to remove the pedal cage. If the bearings develop any free play at all then it is a very good idea to deal with it sooner rather than later; the ball bearings are tiny and they don't share the load well if there is any free play. Once they don't share the load well they wear at a faster rate than normal.

If kept correctly adjusted and lubricated, the PD-M324 pedal bearings (like most SPD pedal bearings) last almost indefinitely.

BTW the tool you need was originally TL-PD33 but tool TL-PD63 may work too. The tool can be had for less than £30 if you shop around. I made my own tool for this job.

cheers

Thanks Brucey
reckon im up to some light lube and the odd application of grease so i'll take your advice on that.
like Cosmicbike says, cheaper to buy a new set of pedals than a specific tool.

the tool isn't that pricey if you shop around (see my earlier post; I edited it)

explains more.

TL-PD63 has a 7/8mm socket for locknuts and a 10/11mm one for cones.

I have recently retired an old pair of Shimano SPD pedals after years of use in all weathers, as the top surfaces have become very worn. And as an experiment I have not removed the axles for re-greasing or adjustment at all, during the lifetime of the pedals. The bearings feel as good as they ever did. In future I won't be touching the bearings unless something feels wrong.

Don’t forget to unscrew the pedals from the cranks, clean the threads, regrease, and refit not too tightly. Do this every couple of months to avoid them seizing in the cranks. This applies to other components as well, like seatpins.
Power to the pedals

Hi All,

I spotted this post from westview and please accept my apologies for adding my own question into but this message/thread is very useful and it got me thinking about my own pedals which at least looks wise are similar although I don’t know whether the construction accessibility etc. are the same or not. However given that I was thinking along the same lines of asking the question that westview has already there didn’t seem too much point in starting a new post.

I have the Shimano PD-T420 pedals on my bike and at the present time I’ve taken this bike to bits over the summer for cleaning/maintenance and I’m currently in the process of putting it all back together. I’ve been focused on other issues such as the IGH and the gear change cable but I’m getting close to finishing those jobs and fingers crossed if I get those finished without trouble it’ll just be the finishing touches of doing things like putting the mudguards and pedals back on.

These are the pedals

https://bike.shimano.com/en-EU/product/component/alivio-t4000/PD-T420.html

Anyway having digressed the pedals are currently off the cranks and I’ve given them a clean but I haven’t done anymore than that. I will give the bindings a spray with lube before I refit them but would the other advice above for the M324 pedals pretty much apply for the PD-T420 pedals as well? For example would I need a TL-PD33 but tool TL-PD63 to access the bearings?

Thanks for your advice!

John

PD-T420 have the 'pastrycutter' bearing retaining sleeve.

this needs TL-PD40 (cost about £2) (plus a 10mm and a 7mm spanner) to service the bearings

http://si.shimano.com/pdfs/ev/EV-PD-T420-3556.pdf

the tool removes the spindle with the bearings in one 'cartridge' assembly;

Image

you can see the pastrycutter collar on the right, and the cone and locknut (to adjust the bearings) on the left.

All this is both a lot easier and cheaper than any other pedal, pretty much.

Hi Brucey,

Many thanks for your message above which is very helpful and much appreciated!

I'll get onto looking up and ordering that tool so I can then get on with this.

Thank you!

John
