Question: how to tune the mechanical governor build into the injection pumps on the various generators - MEP-004, MEP-004 and MEP-006 among others I'd expect.
Under load the weight move slower and the injection pump has two mechanism to hold RPM - the weighted mechanical governor and the auto advance mechanism. These work in concert is my understanding to keep the engine as close to the setting (1800rpm) as possible under load changes.
So have gotten comfortable taking these Standyne DB2 injection pumps apart for cleaning and replacing some leaking seals etc. We do not rebuild per say - just get them working, cleaned up and leak repaired. So they all work well now but we are unsure how to adjust the governor function to optimal performance.
Anyone know this process? We have the TMs and the Stanadyne manual but did not see step by step testing or adjustment process - assume an MEP-005 as the typical unit to be tuned.
