Three pump generations of the 5R110W 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 for 36940-03K is for use with first generation pumps (OE casting numbers RF3C3P-7B324-AA or AB).
