For the 2036-127 pinion I find the following data: pitch diameter, 0.298"; outside diameter, 0.334"; root diameter, 0.224"; number of teeth, 14; diametral pitch, 48; pressure angle 20 degrees; face width, 0.156"; bore 0.125"; radius on one corner of the teeth, 0.031"; material, cold roll steel.
Good luck. Let us know how it turns out.
