I have four MP40s and two MP10s that have been running for years, 2 of the 40s are newer but the others probably at least 5 years old.
I never new I was supposed to grease anything that goes inside the tank the only thing I have had to replace is one wet side that had a bearing noise and I destroyed it trying to replace the bearing.
