2. Unscrew the 4 cover mounting bolts and remove it together with the gasket. After this, the rotors can be pulled out, since the inner rotor has a sliding key that engages with the key of the drive shaft. Rinse the rotors in kerosene and wipe them dry with a lint-free cloth. Clean the pump body with a cloth soaked in kerosene and wipe it dry with a clean, lint-free cloth.
3. Inspect the pump body and rotors for damage, scratches and obvious signs of wear. Pumps of this type typically have a long service life, but over time they too wear out and their performance decreases. If the rotors are heavily worn or if the pump performance has noticeably decreased, the rotors should be replaced in pairs, but since the pump housing on an older engine will most likely also be worn, the timing case may also need to be replaced.
4. Assemble the pump in reverse order. Lubricate all moving parts thoroughly with clean engine oil and install the pump cover with a new gasket (see photos).
