Melling pump cover bolt torque

If you coated the inside of the housing where the rotor rides and gear and coated the gear and the rotor and the plate that bolts to the bottom. I would say that you coated your clearance's right out of the pump.

Yep. Sounds like you need to take the coating off of the tops and bottoms of the gears, off of the bottom of the housing where the gears ride, and off the the plate where it faces into the gears. Seems like 'they' coated the wrong areas for this type of pump.

I would never imagine bothering with coatings in this type of pump.
