Upon arrival of this Toyoda FA450 spindle, our customer mentioned that it had been crashed hard. The damage we observed to the shafts taper and front bearings definitely supported this claim. Because of our In House Grinding capabilities we were able to offer our customer a quick turnaround. Although we were able to repair this taper quickly, we still had to be very methodical about it. This Toyoda spindle has a unique removable tapered insert. It can be separated from the main shaft. Grinding the tapered insert so that it has acceptable runout when bolted back onto the main shaft can be very tricky!

A slight amount of foreign particulate was also observed within the lubrication of each bearing. Much of it was likely self-contamination as each bearing had begun to wear over time. The #1 bearing was lightly brinelled but operational. All other bearings showed indications of typical wear and tear. All bearings, seals and Dueblin coupling rotary union were replaced with new.

We were unsure of how many cycles the drawbar assembly had seen. The assembly looked clean but this isn’t always a good indicator either way. After speaking with the customer we recommended new Belleville disc springs and gripper. The spindle shipped with over 2,300 LBS (10.2kN) of draw force.
