Insert shim under the frame as required; gently rotate the two gears in meshing checking for tightness “not too lose and not to tight” spend time on this

 

 

 

 

 

 

 

 

 

 

Insert fixing screws just nip them up and check the messing again by carefully rotating the flywheel in a forward direction

Turn on  the motor switch and let the projector  run have your finger on the switch just in case, listen closely to the sound of the meshing of the gears
