Super A crank Case noise

Hi guys I have been lurking on the forum for a few months gleaning allot of information from posts. I grew up farming with a super A. My grandfather sold it to upgrade when I was 11. I finally tracked down his old super A. I got lucky and an old local farmer still had it. It had not been started in 6 years but had been barn kept its whole life. It started and ran great. Engine wise all I have had to do was address a stuck float valve in the carb. I have replaced all the engine fluids that the old manual recommends. All save the crank case oil. I had checked it and the case was full but had not gotten around to changing it. I have been messing around with the cultivator using the A in the garden this year. I had noticed a slight whine from the gears in the case under the gear shift that was not unlike one of my old john deers used to make. I had resolved to change the case oil soon. Today I put the disc hillers on and was going to make rows. It was a pretty cool day here in Alabama. I let it warm up before heading out. Halfway through the first row all of a sudden the case started making a noticeable metallic clicking noise coming from under the gear shift that it had not made before. It was not under heavy load, in fact I would say minor load. I immediately stopped and reduced throttle. Stopping and reducing the throttle subsided the noise greatly but I could still hear it. After testing a little she seemed to go ok even with the noise so I slowly headed back to the barn and parked her. I was hoping for some suggestions of what could be going on from you that have had the case apart. The noise sounded like it was coming from under the gear shift and was proportionate to the speed and load on the tractor.. Could something be out of sinc or lost a tooth? It is defiantly a metallic clicking. Could the noise be a result of the old oil in cold conditions or do you think there is defiantly some damage? I was hoping to use her this summer and refurbish next winter. Any suggestions?
