Do vintage wheels fit on current mini pots?

[wastedyouth]

I have what are believed to be vintage wheels for the rhythm circuit. I have a current fender CTS mini pot and the wheel ID is too small. The pot shaft measures .157 and the wheel Inner diameter .155 inches. Can anyone confirm this? I wonder what the AVRI or Japans wheels measure.

A difference of .002” is probably within tolerance of a mass produced part.

Well .157 inches corresponds to 4 mm. I am thinking the current pots and wheels are made to metric dimensions.

EY specifies their current USA and Japanese compatible wheels ...

4mm on USA, 6mm on Japan ...

USA

Outside Diameter:25.7mm(1.012")
Thickness:6.46mm(0.254")
Center potentiometer hole diameter:4mm(0.157")

Japan

Outside Diameter:25.1mm(0.99")
Thickness:5.75mm(0.226")
Center hole diameter:6mm(0.236")

Maybe vintage MIA wheels were a fraction smaller (or maybe tolerance as suggested, although you would think they would allow enough wiggle room that they would never be too small) ? EY sells complete wiring kits so their USA-compatible wheels do fit current CTS pots.

Thanks this was helpful! So I got a pair of Fender knobs 0054455049, and they measure ~ 0.163” (4.14 mm) so plenty of clearance for a new Fender CTS pot shaft.

Now I have a set of each old and new, I guess I will keep an eye out for the correct vintage pots at a reasonable price for the old knobs.
