CNC cut Brackets for Dynavibe and Aces prop balancer sensors. It includes a bolt adapter that is used to attach both of the brackets to the case halve bolts. The bolt adapter is used to attach to the 1/4 in case bolts used in lycoming engines. There are 3 threads extending beyond he case halve nuts and the bolt attaches to those threads enough to firmly attach the brackets during propeller balancing. Using the case bolt adapter prevents the need to remove a case bolt and altering the original torque value. I can also make case bolt adapters for continental engines. The RPM sensing bracket is reversible so it can be used if the case halve bolts are inserted from either side of the engine. sensors not included.
