This weekend I pulled my 6K Onan out and found the tracks on the lower sides of the drawer slides were bent down and ball bearings had escaped. I bought new 3/8" ball bearings and hammered the rails back into approximate position and switched them from right to left. The operation is now smooth and the generator clears the bottom of the cabinet.

I think I know how the slides got damaged: I recently installed the pertronix electronic ignition. It required that the timing has to be set properly for positioning the magnet on the flywheel. I had to pull the flywheel off to clean it because I could not see the timing marks. When I retorqued the flywheel bolt to 40 ft-lbs the generator was fully extended on the rails and I put my weight on the torque wrench. The drawer slides are rated for 500# static weight and the gen set weighs 479#. Putting my weight on top of that certainly exceeded the rail capacity and bent them.

In the future, for anyone attempting this procedure, have the genset as far back in the cabinet as possible and push the torque wrench to the side rather than down to avoid overloading the rails.
