This electric gate motor had rusted badly on the base and there was no fixing to screw it back down.
I had to make a couple of bracket fixings using two pieces of 25mm square metal. The holes in the concrete were drilled out and new anchor bolts fitted to screw the brackets to. The gears from the motor to the gate were aligned before final fixing.
After everything was put back together and was working the gate was adjusted for travel and the gears lubricated with grease.
