1. VOLUME BASE
Konami Part UNKNOWN
U Bracket. Has a 14mm hole in the center to fit the volume shaft's bearing and a slot for the potentiometer assembly tab to fit into.
2. BOTTOM BEARING
Konami Part UNKNOWN
MF148ZZ
3. VOLUME SHAFT
Konami Part UNKNOWN
6mm to 6mm female to male coupler/extension shaft that adapts the pot's stem to the knob head. Has a hole directly above the coupler for a φ1.6mm L12mm dowel (a) that the torque limiter sits on. Takes 2x M4x4 hex set screws (d) with "W point" cup and conical tips to couple to the pot shaft. The bottom-most part of the shaft is 12mm in diameter to accommodate the bearing MF148ZZ(press fit onto the shaft). There is also an e-clip on the shaft above the torque limiter but below where the bearing block would sit.
4. TORQUE LIMITER
Konami Part UNKNOWN, TOK TLE1-618-5W, TOK TLEU1-618-5W variant
A hysteresis bearing type torque limiter, commonly used in expensive printers on paper feeders. Smooths and dampens rotations from jitter and excess spinning. For specifications see Tok's respective product page
5. VOLUME COVER ASSEMBLY
Konami Part UNKNOWN
Meta part assembly consisting of parts 8 and 9, below. Appears to be threadlocked together from the factory.
6. VOLUME KNOB
Konami Part UNKNOWN
This part is NOT dimensionally identical between the Nemsys and Valkyrie Volume Assemblies. Valkyrie knobs have a 2mm counterbore underneath the knob whereas Nemsys knobs have a 2.5mm counterbore. Valkyrie knobs fit on both assemblies without issue, Nemsys knobs on Valkyrie assemblies have a risk of rubbing
The metal thing you turn with your hands. Machined out of solid aluminum, takes 2x M4x5 hex set screws (c) with "W point" cup and conical tips to secure it to the 6mm shaft. φ30/H25mm, has a lip to prevent backing out and is ribbed. A few vendors sell an aftermarket knob compatible with the arcade cabinets.
