Guest oldodgeboys Posted June 18, 2009 Share Posted June 18, 2009 <span style="font-weight: bold">My 25 DB oil pump vanes have tip profiles of being almost fully rounded. There is some wear, so I can’t really tell what the original/correct profile should look like. I know these pumps are not 'high-output' pumps. They're probably more <span style="font-style: italic">mediocre-output </span>than anything else. Still though, my pump pressure build-up is sure slow.Given that there are several factors that contribute to oil pressure and rate of pressure rise; does anyone know if the oil pump vane tip profile significantly affects the oil pressure?Does anyone know what the original/correct profile looks like? Should they be rounded, or more flat on the pressure side, or ??Thanks to all.</span> Link to comment Share on other sites More sharing options...
brian1925tourer Posted June 23, 2009 Share Posted June 23, 2009 the vanes for your pump should be rounded with 1/8 radiusregards Link to comment Share on other sites More sharing options...
