Trying to repair my pump after Idaho and having issues. I have older Dom pump with smaller Ring bore in housing what should bore be to run newer style wear rings and does anyone run an ring insulator? Or do i just recut bore .002-.003 under ring size and drive in ring metal to metal?

id suggest using an insulater for sure.throw your wear ring in the deepfreeze for abit as it helps abit in the instalation process! good luck

zipper , the berkeley housing bore is 7.749" . if the old dominator bore is small enough to machine up to a berk. wear ring without an insulator , i'd go for it in a riverboat .

going in my race boat....just trying to get concensious if I should use insulator or just go metal to metal and interferance fit wear ring to pump housing after I bore the pump housing bigger. Wocket sent bore spec's which appears the bore size is 7.750 or as you stated 7.749 to accept newer style wear rings w/insulator. the question now is, do I use an insulator in race applications. pump will be harnessed to no more that 550 HP, 575 torque. .Thanks RPM
