View Instructions Find a Distributor

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. Carbide reamer for 36940-03K is a replacement carbide reamer for F-36940-TL3 or F-36940-TL3C tool kits and can be used with all pumps regardless of pump generation.

Sonnax F-Tool kits designed to service a specific bore require the VB-FIX, a self-aligning valve body reaming fixture. Sonnax oversized base plate VB-06 must be used in conjunction with VB-FIX when reaming, unless stator support shaft is removed from pump body.
