It appears that my engine will need lots work (bore, align bore, new cam and lifters, etc.) and I don't want to reinstall the old oil pump if there is ANY doubt about it. Specs call for "radial clearance of 0.08 to 0.14 mm", and is this the clearance between a gear tip and the interior wall of the pump? "Flank clearance of 0.15 to 0.35 mm", and I assume this means that this is the allowable spacing between the closest point of approach of the two adjacent gears. Anyone care to confirm or refute? Feasible to rebuild a pump or better to replace?

Many thanks!
