replacement pivot point "bearing plates" on the am   Posted: Fri 01 Sep 17, 16:18    Reply with quote

Hi there.

I have too replace the round, white plastic which are sitting on the amas pivot points.

Does anyone has done this?

What kind of material is it, or is there a better material to take instead of the original?

Mine are worn out by the sun.

Did someone got the drawings/measuremets for the 920?

Would be easier to get them water cut with cnc data.

Best regards Björn

Teflon PTFE sheet is the right material for these. UV resistance is good and it is low-friction. Nylon is NO good because of UV.
