Service interval for Dura Ace 9000 or 9100 series pedals?
I’ve been using Dura Ace PD-9000 & PD-R9100 pedals on my 2 road bikes. I really like them. They are lightweight and they are easy to click into and out of which makes me feel more confident starting out at stoplights and from a dead start. Pretty much plug-n-play. Even the cleats are super reliable with recessed Allen bolts that stay put.
My issue sue is that I feel like they loosen up over time, allowing grease to leak out then developing either slight play or slight clicking sounds while climbing out of the saddle.
I rebuilt the 9000’s and was pleased at the precision of the bearings and satisfied that I had locked the cone down correctly with the locknut. Apparently it was not tight enough because here I am, 1,000 miles or so later and one of them has loosed up and had quite a bit of play so it will require adjustment and a possible re-build again.
Just curious if others who who are using the rebuildable Dura Ace pedals have run into any durability issues and perhaps could offer some tricks on how to keep them in proper adjustment for longer.
BTW - I weigh about #190 and I do quite a bit of standing climbing. With that said, I have never been what you would call a “masher” preferring to (usually) keep my spinning efffort light to moderate.

I think I might have just failed to sufficiently tighten down the locknut against the cone.

That does not seem right. I have a set of 105's on both my road bikes and never have done a thing to them in 4 years. I am guessing the one set has 20000 miles on them easy and work like the day I got them.

I think the Dura Ace version might be different enough that you could have your 105’s or your Ultegra’s and they will run a long, long time with no maintenance like that. I believe the axle cartridge may have cartridge bearings where on the Dura Ace it is just 2 rows of 3/32” bearings. As far as I know, once the Dura Ace bearings are re-packed correctly with good grease and adjusted to remove all play and the lock nut is locked down securely against the cone - I believe these could also be good to go for many thousands of miles. I may have made an error of not locking something down tight enough on my first try.

Here is the schematic I have been working from: https://www.paul-lange.de/index.php/...-9000-3329.pdf
As you can see, there are 17 inner bearings and 9 outer bearings, both 3/32”. I managed to lose on on the floor like a dummy - I purchased a 200 count quantity of them from China in this size for $5.99.

I have the mountain version of your pedal. I relube every 5000 miles. With your pedal you remove the axle unit, clean out the housing, pack grease into the housing and install the axle unit forcing out the old lube.
