To open the PD-M540 Pandora's box?

[Guest Big H]

I see in the new Bicycling Magazine they advertise Ceramic Balls....... are they any good. For the price they must be??????

 

Oom I'm not sure about 'good' but I don't think they'll make me or you go any faster that's for sure ..........

 

Oh No!!!!!! Da ya mean it will not improve me to do a sub 3 hours 94.7!!!!!!!!!

Ok so all said and done, are all the bearings ( balls ) in the shimano MTB pedals the same? I have 3 pairs I need to service....... Pedals.. not balls

Pick your model here:

The under technical docs / exploded view you will find the size.

Did someone actually do this before?

 

 

"if you can't be bothered to go through the fuss of removal and servicing, drilling a small hole into the pedal and injecting grease periodically is a perfectly acceptable alternative. Secure the pedal safely in a vice (using soft jaws if you have some) and mark the spot to be drilled with a sharp punch. Use a 2.5 or 3mm drill bit to carefully put a small hole in the end of the axle, through the cap. Clear away all metal shavings carefully before reattachment"

I take it that allen bolt isn't coming out with usual methods...?

No, very "crude" gries-nipple.

 

Must say, I like the idea...

[Azonic]

Correct, IF you can plug the hole after you've put grease in, otherwise you're just opening up another hole for water and dirt to get in.

oh, damn - how could i missed that

 

No they actually insert selftapping screw to seal the hole. Would prefer proper nipple though.

 

"The tip of most grease injectors should fit snugly into the 3mm hole, but the hole is small enough for the surface tension of the grease to keep it from oozing out once it's settled down. If you prefer, you can install an appropriately small self-tapping screw to prevent leakage. About every three to six months, depending on how much you cycle, chase out the old grease by filling the pedal again. Wipe off the excess and ensure you push the rubber dirt seal back into place"

 

[Azonic]

If you can push the new grease all the way through and "pump" out the old dirty grease I rate you got a winner.

[Johan Bornman]

Campag hubs and headsets work on this principle. In 9 years I have not once opened my Campag Record hubs. I just keep on injecting fresh grease in, the old contaminated grease comes out in sneezes and snorts as you ride and the bearing always have perfectly clean lubrication.

 

If the pedal allows a clear passage for the grease to pass right through, it would work. However, you'll have to pump a lot of grease through there in order to get the old grease from the furtherest corner out.

 

On Campag hubs you pump the grease in the centre, making the path shorter and waste less.

 

The only problem with this system is the absolute rubbish Exus grease guns we get in ZA. I have three, of which two never worked properly for one minute.

 

A syringe works for wheel bearings but you can't get a syringe into the centre of a hub. Besides, the nozzle is too big.

the old dura Ace hubs can also be fitted with grease without opening them, but ehre it works from the side. I had a long and absurd discussion with a bike shop owner in Stellenbosch once whose opinion was, that it's not enough to just squeeze the new grease in and he refused to do the job for me. Very good businessman as I went to another bike store, asked them if I could use their grease gun and they elt me do it for free - Flandria

I've drilled out pedals in the past as shown. I then tapped a M2.5mm thread and fitted a M2.5 grub screw. it works well but as Johan says, you pump a moerse lot of grease into the pedal making it heavier.

 

I find that a simple service once a year is adequate.

 

I usually buy the Shimano Genuine Part Ball bearings. They are grade 20.

 

Ceramic balls are also awesome but they are designed to run on even harder steel races so they may wear your hubs races out.

 In Europeyou can purchase new races for the hubs, both Campagnolo and Shimano (upper end stuff ). In South Africa COolheat does not seem too interested in supplying the required tools and spares.

 

Still waiting for a Shimano Saint Lock ring tool.... Where's Steve?

[Johan Bornman]

Does the Saint tool look anything like this?

 

[GoLefty!!]

Nope. It looks like a larger version of the std Shimano Lock ring tool.

Part number is TL-LR20.

 

Been on order since February..!!

Would be a waste to order it online but it may be the only answer
