Im not sure which engine you have but if it is a 7c (small engine same as a ten) I just bought some exhaust valves from aftermarket express out of florida they were part number 4b7264 that takes the double ring wedge shape lock collar, there is a different exhaust valve option that takes a single ring lock clip, im not sure where to source those.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.
