Dapol Class 121Slipping Drive

 18/12/2024

This is the second time the drive shafts have failed! The knuckle on the end of the shaft just slips. Unfortunately there are no spare parts available at the time of writing. Fortunately I have the old set from the previous failure I cleaned the parts in isopropyl alcohol run a triangular needle file across the mating portion of the shaft and glued the knuckle with cyanoacrylate. That didn’t work Dapol will supply them on an exchange basis. So the loco and the defective drive shafts are going back after the holidays


 UPDATE

Replacement drive shafts have arrived back; I’m glad to see that the design has been changed. To my mind this is a much better design.
