How to remove lock ring on TCM crank drive

[Greg J]

Hi all,

title says it really. I noticed forum user Trex wrote about re-greasing a TCM crank drive. I want to be certain that the lock ring thread is left handed as you would expect. Also any advice on how to improvise a suitable 4 pronged spanner would be appreciated.
Thanks,

Greg J

The thread is left handed and over time, can be very stiff.
you need a special tool for it.
You bolt the tool to the ring with the 8mm allen crank bolt and it the arms with a 16oz mallet.
