Hi

My formula 27 has a English axle setup it seems and was wondering if anyone could help with identify these 2 diff's which are with the car. One is currently fitted, the other is spare and came with the car.

Here are some pics which might be useful to others also.

Codes are T24 ----- 73AG4025CA
T13 ----- 73AG4025CA

















Many thanks

Thats the casting number -- you will need to count the teeth or count the turns to find the ratio.

The ratio is stamped on to the edge of he crown wheel for the spare diff. Looks like 8/33 or similar.

Hi as daviep has said but if it is hard to read as it is sometimes. It should also be stamped on the end of the pinion also. Usually a bit easier to read than the stamping round the edge of the crown wheel.
