I was driving through the back yard on my '48 S/A to put it away when I heart the loudest crack.
I had been doing some light dirt moving & was just "crusin" back to it's parking place.
The crack was followed by a tik tik tik which continued 'till I parked it. When I let the clutch out the tic tic tic came back.
Ok, that means it is in the transmission.
In looking at the picture in the service manual the only gears in mesh while in neutral must be the reverse idler set.
Am I correct or am I missing something?

The "constant mesh gear set in the very front of the trans (on the input shaft) and front of countershaft always "mesh"
I imagine a piece of a bearing or other metal got between thos gears and broke off a tooth.
Sorry, JimN
 
Jim's right. Did you feel a little free wheeling. I have an Oliver that did that. It actually worked fine, but would coast in high gear. Pulled the tranny plug and found my problem. It was my birthday too. Talk about a bummer birthday gift.
 
The reverse idler gear slides when shifting into reverse. As I recall, that engages it with the gear on the lower (output) shaft and it is always meshed with the upper gear. The only other gear that is meshed in neutral is the oil slinger gear, which is the rearmost gear on the lower shaft. In neutral, the lower shaft does not move and the oil slinger is running on a bushing.

Since the oil slinger is die cast, it is soft and easily picks up chips that can cause a tick. Any noise in neutral is likely to be from the oil slinger. Other posibilities are the reverse idler or a bearing on the top shaft. They are all that is moving in neutral.

Don't know what the loud crack was. May have been the oil slinger destroying itself. Could have been caused by ice.
 
Actually that turned out better than I expected. A neighbor's story started out much the same but ended with a septic tank replacement, a lot of soap and water and a considerable loss of religeon.
 
I suspect the oil slinger gear broke. Take the top off of the transmission and have a look inside. The oil slinger gear is made id real light metal and will look different than the other gears-besides being broken I mean. Dave
