Toyo Spindle repair and rebuild_before and after

This Toyo HFD05-37 spindle was sent to us from a return customer in Asia. We’ve repaired dozens of Toyo spindles for them over the years. This particular one was sent to us with a note: “Spindle is running sluggish!” Although the shaft turned freely, it rotated with significant stiffness. The main reason for this was the simple fact that it was very worn. Internally and externally this Toyo spindle was in need of attention.

Toyo Spindle repair and rebuild_stator

We thoroughly test all Toyo stators upon evaluation. Although this stator passed all testing, we still removed it from the main housing so we could replace the stators coolant jacket seals and clear any obstruction within the coolant pathways.

Toyo Spindle repair and rebuild_power connector assembly

Many times the power connector assembly is damaged upon our receipt. This connector was crushed. Locating and procuring a new connector with the proper pin out and identical connector housing can involve tedious hours of flipping through the pages of catalogues. But when we say that we return your Toyo spindle to new condition, we mean it.

Toyo Spindle repair and rebuild_new data tags

Most of the Toyo wheelhead spindles we rebuild have lived a rough life. More often than not the data labels are corroded and illegible, such as this one. If our customer accidentally attached the coolant line to the lubrication inlet it could quickly destroy the bearings. We provide new data tags to prevent this from happening.

Toyo Spindle repair and rebuild_bad bearings

We replaced all bearings and seals with new and also changed out the original power cord harness with four feet of new Liquid-Tight conduit. We performance tested the spindle at max speed (50,000 RPM) and gave it a fresh coat of industrial epoxy paint. This Toyo HFD05-37 spindle looked and ran like new!
