I am building a spare motor and cant decide/confused if the oil pump is serviceable.
Inner to outer rotor clearance - 3.5 thou. (some specs on the forum - no specs in my 77 D Yamaha manual).
Side clearance (straight edge across housing, feeler guage between straight edge and top of rotors) - 3 thou.
Thickness of rotors - .314"
Assembly spins smoothly.
No gouges, grooves or visible wear.
Seems like im on the outer limits - new pumps from Mikes seem to come with hassels.
