Used Adam Computer Data Drive Encoder wheel with matching top cap and encoder plate. Taken out of a New style JVC drive requires the new style black cover and encoder plate to use which comes with encoder wheel. Will fit in ALL Adam Computer data drives but have to use the top cap and encoder plate that comes with the encoder wheel.
If you have a US drive and the wheel has turn into goo you can use this to replace that mess.
This is the encoder on the hub with rubber wheel. Rubber in good shape. Encoder str8 not bent. NOT tested taken out of a non working tape drive sold AS IS.If you need Adam Computer parts I have them just let me know what part you need and I will put up a ad for it.
NOTE Out of handle controller cradle, power supplies, and Disk drive bottom boards.
