Servicing a Crank Lock Out Tensioner
Does anyone know how to service a Crank Lock Out Tenioner head?
I have a Eagnas Smart 808 6-point machine that has gradually started to lose it's consistency. When calibrating the tension with digital scales, I find that one test to another the tension can vary up to 0.5lb now. Sometimes a little more.
The tension seems to vary particularly when I crank the tensioner quickly or very slowly. I have noticed that the string clamp plates are not holding the string as well as used to too.
I am wondering if anyone on here knows how I can service the tensioner and hopefully resolve some of the problems I am experiencing?
Many thanks for any help in advance.
This is the machine I have:

Have you tried servicing a crank head and do you know how to make the gripper grip better? I've tried cleaning the plates but it seems it may be that the ball-bearings are shifting to one end and so the grip force is not as even.

You could always take them apart and clean the faces with a toothbrush and rubbing alcohol - sometimes gunk can build up and impede grip.

I thought there may be parts that need periodic tightening etc. No probs, thanks anyway!

You could try putting some tape with a reasonably abrasive surface (think masking tape rather than electrical, for example) on the gripper plates to give a little more traction.
