In the later manual it specifies the clearance between the vane and pump body as 0.020” – 0.030”. The clearance on my original water pump (the one with nut at the end of the shaft) is 0.100”. What should the clearance be for the first generation water pump? It doesn’t seem reasonable there should be such a significant difference.</p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Harold<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p></div></div>_______________________________________________<br>
