Three pump generations were produced, with varying casting hardness. The Sonnax reaming tool kit used must be matched to the hardness of the pump to extend reamer life and bore finish quality. Sonnax reaming tool kit F-36940-TL3 is for use with first generation pumps, while F-36940-TL3C can be used with all pumps regardless of pump generation. See instructions for details.
