The small crank on the right cannon is broken. I have replacement parts for both cannon for the small and long cranks. I was just looking for any advice before i got started. The larger cranks look easy to replace, but the smaller ones look to be a challenge to access. Looking for some helpful suggestions,thanks

Iirc they are easy to do ,
I think the cannon has to be in a certain orientation that leaves access via a hole in the bracket or something.

Thanks- you were exactly right . There is a hole in the bracket that will allow access to the connection of the large and small crank. It was a walk in the park , once I saw the (4) machine screws that held the motor to the bracket. I had to drill a hole in the new small crank arm for the roll pin.This portion is complete. I assume that on start up of the game the cannon motor will run and the (2) switches will orient the cannon in its home position. I think there is a little bit of adjustment on the topside with (4) screws that attach the gun shaft assembly to the plate nut.

Maybe the diagram is missing in my manual. On page 2-32 the parts are listed for the U-gun Motor Bracket assemblies, but no diagram.

My canons have always done a complete cycle on initial start. There was a time that the left canon would activate more than once and it would cycle a few times. But that ended and now for the last few weeks the right canon makes about 5 passes as the solenoid activates a handful of times. Then all works normally. Anyone else had this issue?

How do I get that metal pin out of the motor axle so I can connect the small crank arm? I can't get it out and I'm afraid to damage the motor.

Quoted from Cenobyte:

Although this may not be the correct procedure it is what I did and it ressulted in no damage.

Lock the axle very securely in a vice, oriented so the pin is sticking upward. Use a hammer to gently tap the pin out the other side.

Hey there! Got a moment?
