When installed with a flutter analyzer, T/REDS are the only rollers which may be rotated and safely locked in any position on the capstan shaft to minimize rotational error and optimize flutter performance.

Recommended: add a pair of 2" swingarm return springs for just $9.25 (regularly $12.75).

With the "End-of-Life" looming, we've added an option for specially sealed product packaging so you can buy now and save them for much later. Check the option above and your T/REDS will arrive in heat sealed protective HDPE packaging with included moisture adsorbing desiccant packs. Storage per our instructions will extend the storage life of your T/REDS to an estimated 10 years to guarantee you'll have a fresh set when you need them.

Made in the USA (PMI/Kollmorgen), heavy duty, direct replacement motor kit for the O.E.M. Yaskawa disc motor. Superior current handling capability. Fits all MTR-90 /100 / DTR- 900 & Mitsubishi Capstan motors.

Our "NEW" motor kits are USA made, and are not interchangeable with the OEM Japanese parts. As such, individual parts are not available for field repair. At our discretion, we may sell you the complete motor parts kit only.

Motor kit availability is limited and to be warranteed they must be installed in our shop. We reserve the right to determine your qualifications for "in the field" installation. You must contact us before placing your order. Thank you!

Restored/reconditioned original equipment parts are tested good, with plenty of remaining life.

"Do-it-yourselfers" note that PMW is not responsible for motor failure due to improper field installation of parts. The servo-disc must be installed with proper clearance above the "flux return plate" and must be set with a "feeler gauge" or shim. The proper specs will be provided to you.
