I posted this yesterday as a reply to another post, but I think it got lost in the shuffle. :frown:
"Well, after reading this post, I determined to take a look at my oil pump, since my engine (948) is out of the car and discovered that its pump is a Burman type. Not sure of how to check for wear, but the vanes seem to be where they should be; up against the cavity wall. I would assume that each vane should be checked against the cavity wall after the pump shaft has rotated 90Âş in turn. Should there be some clearance or should the vanes be tight against the cavity wall with no clearance at all? Note that in the WSM clipping, there is a write up for checking the Hobourn Eaton type, but nothing for the Burman."
After thinking about this for a while, I've determined that because the vanes slide in their mount, there should be no clearance between the vane and the cavity wall. If there is, then the pump is worn and should be replaced. :confuse: Can anyone knowledgeable about these pumps confirm my assumption?
