I have 2 Viscounts, one which I have had for 40 years+ has ball bearing pedals just like most of my other bikes which are adjustable with a nut under the cap. My "new" Viscount has has pedals with an Allen bolt in the end of the spindle. I want to adjust the end play on these but this design is new to me - any advise would be greatly appreciated Attachments:

I believe it’s accomplished with shims. I did an internal search for “pedal shims” and came up with several posts on “Lambert Pedal Overhaul”. I need a refresher myself as I have several pairs to rebuild.
Best,
John “wheelson”

Here is a starting point:
Unfortunately I don't know what happened to the photos I posted. At some point I cleared away hundreds of photos of bike parts from my Google Photos account and probably these were among them.
Basically the end play feels annoying but is not a functional problem. I am wary or these pedals because of the generally poor workmanship of the castings, although the mechanical parts might be OK. Still, nothing will ruin your day quite like a snapped pedal spindle.

The Aerospace Pro pedals that you were asking about have needle bearings.
These have no adjustment for radial play, and don't care much about end-/axial-play.
Viscount did offer shims, but only really as a courtesy to the fretful.
If you have radial play the solution is a new bearing (sadly, it's a non-standard size).
Donor needles might help you get by, but need to be the same diameter to within microns.
Unfortunately, if used without end caps, grit/water gets in, and wear follows very quickly *.
Although needle bearings are capable of taking large loads and in a small sized unit, they
are susceptible to damage from poor maintenance. Small amounts of grit/dirt/corrosion
that can "escape" around a ball, get embedded in the sidewall or roller for a needle bearing.
Viscount supplied later AP's with conventional cup/cone pedals (eg, the Olimpic 64 pedals).
When you tighten a cone axially, it pushes the balls radially, taking up play in both directions.
Less radial play is good as it reduces point loading at the top of the cup (so it lasts longer).
I'm refurbushing several sets of AP pedals, and always on the look out for donors, needles,
and information on the bearings. I can see spares in the Viscount dealer manual but I have
yet to find any "in the flesh", but if I can help you, or you have news, feel free to PM me ...
HTH,
Rod
* Viscount did not employ a seal on the inner bearing, so water can get in at the crank end.
Frequent, generous re-greasing with water repelling grease helps a lot (eg, Motorex 2000)
