3. Multi-Pump Drive Adapter
The oil level is easily checked by looking at the sight gage in the center near
the bottom of the multi-pump drive adapter. Lubricating oil should be half way
up the sight gage. If low, lubricating oil may be added by removing the
breather located on the right side of the Multi-pump Drive Adapter. Draining
the lubricating oil may be done by removing the 9/16 socket head pipe plug on
the bottom of the Multi-pump Drive Adapter.
4. The preferred lubricating oil for J&M vibration cases and multi-pump drive
adapters is a “High Moly Oil” (Schaeffer 268). Longer intervals between oil
changes and fewer maintenance hours spent on mechanical service can
generally be realized with this oil.
Therefore, whenever the "first preferred" oil is not available or desired, and an
alternate oil is selected, it will be necessary to test and/or change the oil at
shorter intervals.
Extensive tests have indicated that the use of Schaeffer 268 results in cooler
operation and extended bearing and gear life.
The vibration case and multi-pump drive adapter lubricant installed at the
factory is SCHAEFFER 268 but the following gear lubes may be used when
changing lubricants:
