Are you looking in the right place for the block serial number? All production N’s had a serial number. It’s located on a cast boss behind the oil filter canister near the head; hand stamped. All 9N & 2N’s used the ‘9N’ s/n ID and the 8N used the ‘8N’ ID. Early blocks had a star symbol prefix and suffix to designate steel cylinder sleeves were used and in 1951 that was changed at s/n 263843 to a diamond symbol to define that cast iron sleeves were used. In 1949 the 8N went through a few changes, one being the steering box was revamped at s/n 216989 and now used the ‘late’ steering box. Don’t rely on a s/n for much though. ID your setup by whether it has a front mount distributor or a side mount. Engine blocks got swapped out on occasion. You could have an 8N block in your 9N and vice versa. Here are pictures of the early and late steering boxes. You can find service information in your 8N Operator’s Manual; the I&T FO-4 Manual; and the 39-53 MPC. The 39-53 MPC has exploded view sketches of both boxes with all the parts shown and part numbers listed too.
