After a bit of a hiatus, for no good reason here’s another pedal refurb!
I picked up a box of tired pedals, that have now sat for a while in my basement, but a drizzly Sunday calls for greasy hands.
First ones on the refurb bench are a pair of PD-A550s, mid 90s clip pedals from Shimano. They should have some clips and straps, but these have been broken and the straps lost. No luck yet finding replacement clips and straps.
Most pedals seem to require special tools to open for a service, but these can be opened with just a spanner.
A neat design, the clip can be adjusted forward and backwards for shoe size.
So let’s get this open! All it takes is a 17mm spanner.
All pedals have small bearings on either side so be careful not to lose them. If there’s still some grease they’ll stay where they are, otherwise they can fall out. If they do they like to hide under things and go farther than you’d imagine!
Here we can see they’re happy where they are, though there’s not much grease down there. All clean, no corrosion.
The races look good, no scoring from being over tightened or from dirty, dry bearings.
Let’s get the bearings out, clean them, remove any grit and regrease them. The grease here looks good, but is probably from the mid 90s.
On closer inspection, the build quality and finish of these pedals isn’t quite up to what we’ve come to expect from Shimano. You can see some artefacts from the casting which haven’t been removed.
There’s a few of these on various parts, including the inner bearing race. You’d normally expect this to be very smooth.
Back to the overhaul, I always clean bearings with some kitchen paper, pretty straightforward. A spot of WD40 helps dissolve bits of grime that can’t be otherwise easily removed. Just make sure to clean it off, or it will contaminate the grease.
Races and spindle nice and clean, time to rebuild!
All in all this took maybe 15 minutes, so definitely worthwhile doing to get the bike ready for the new season. Just make sure not to over-tighten when reinstalling. It’s worth a little patience to find the sweet spot, no wobbling spindle, no crunching bearings. You can feel when it’s just right.
Now I wonder if that reflector is supposed to be bent back like that, or whether it should be perfectly perpendicular to the pedal? Any ideas? Most photos of these pedals don’t show the front reflectors but I think they are original as one NOS ad I saw seemed to have them.
Another job done! Shall I pop these on my mid 90s Colnago?
