Trying to MathF.Clamp y axis rotation results in x equal 270 and y equal max value instantly

I am in the process of prototyping several Amusement Park style rides for an upcoming relaxation program. One of the rides is a rotating airplane ride where the individual arms will go up and down with a maximum rotational value of, say, zero to 45 degrees.

This is what I'm using for my rotational scripts:

     void Update () {
     
         if(rotateMe)    {
 
             this.gameObject.transform.Rotate((X_RotateSpeed * Time.deltaTime), (Y_RotateSpeed * Time.deltaTime), (Z_RotateSpeed * Time.deltaTime), Space.Self);
 
             tempAngle = transform.rotation.eulerAngles;
 
                 if (limitX)
                 {
                     angle = tempAngle.x;
                     angle = ClampAngle(angle, lowLimitX, highLimitX);
                     tempAngle.x = angle;
                     transform.rotation = Quaternion.Euler(tempAngle);
                 }
                 if (limitY)
                 {
                     angle = tempAngle.y;
                     angle = ClampAngle(angle, lowLimitY, highLimitY);
                     tempAngle.y = angle;
                     transform.rotation = Quaternion.Euler(tempAngle);
                 }
                 if (limitZ)
                 {
                     angle = tempAngle.z;
                     angle = ClampAngle(angle, lowLimitZ, highLimitZ);
                     tempAngle.z = angle;
                     transform.rotation = Quaternion.Euler(tempAngle);
                 }
 
         }  // end if rotateMe
 
     }  // end Update
 
     private float ClampAngle(float cAngle, float min, float max)    {
 
         if (cAngle < -360.0)
             cAngle += 360;
         else if (cAngle > 360.0)
             cAngle -= 360;
 
         cAngle = Mathf.Clamp (cAngle, min, max);
 
         if (min == max)
             return cAngle;
 
         if (cAngle == min || cAngle == max)
         {
             atLimit = true;
         }
 
         else
             atLimit = false;
 
         return cAngle;
     }
 

The central column only has a Z rotation speed, and with no limits selected it rotates as expected on the Z axis.

If I set an arm to have a Y rotation speed, the arm slowly lifts an continues to rotate a full 360. The arm does not dislocate, maintaining position as it rotates on the 360.

However, we don't want to dump out the passenger. So I tried to set up a clamp with a zero-45 limitation and then re-assigning the value back to the rotation. In the Screen Shots, the blue plane is the one with the assignments.

Setting LimitY to true, as soon as I start the simulation in the Editor, my x-value is automatically set to 270 my y-value is set to 45 (or whatever the maximum is) IF I assign a low value to the rotation speed (like 5) but if I set a very high rotation speed (like 50), I observe my z-value set to 270, my y-value set to the max y and my x-value will increment until it hits 90. In both cases, once it hit's the 'assigned' x value (either 270 or 90) the airplane will no longer move up or down, but maintain it's facing and slowly move in a circle, with the arm acting like a piston on a train. Also, the actual Y-rotation does not appear to take place. The Arm itself seems to have rotated not quite 90 degrees clockwise from initial position of the arm, and then will rotate to keep the blue plane as close to that point as possible.

I have to assume the fault is within my ClampAngle function, but I've used the code I found in another forum to address having an object rotate with limitations on a specific axis, so I'm not sure what I've entered in incorrectly.

Any advice would be appreciated.
