ball bearings that is. If you change your trigger to a flat or 2 finger trigger it is very important to fully seat the ball bearings flush on the trigger. This applies to any new Difalco controller using my new design hardware. The copper ring that is under the front ball bearing carries the wiper arm connection and failure to fully seat it will stop the controller from working.
This has only come up one time on a repair I just received but I thought everyone should be aware.
If you replace your trigger that has original Parma hardware it is also important to fully seat the bearings to keep any side play from developing over time.
Thanks, Jim Difalco
