heating in the truck area only

[myshop1044]

I replaced the "Y" motor asem the other day, I removed the "Z" truck cleaned the bearings and replaced it afterwards.
I did a couple of 20 min carves using the carving bit, 1/16 strainght cut bits and I felt heat at the CT head as I was changing the bits out.
There was no heat on the flex shaft at all. I did another test carve today about 6 min and the heat was there again.
Any Ideas as to problem. I did not have a heat problem before I remove the truck for cleaning.

The truck can take a lot of heat so I would not worry that much, but it could be time to replace or inspect the carving bits.

It has been posted that the CT will run HOT during the break in period. You should be OK....
