Oil Suction Screen cleaning?

[Learjetter]

In addition to the pressure screen or spin-on filter, do your mechanics remove, inspect and clean the oil suction screen during oil changes?

At the bottom of the IO-360 accessory case are provisions for two oil screens, a suction screen and a pressure screen. The pressure screen is larger and protects the oil distribution galleries from debris. The pressure screen is removed, cleaned and inspected at every oil change. Many owners replace the pressure screen with an adapter and a spin-on type paper filter, or the Challenger metal spin-on re-usable filter.

The oil suction screen sits just to the left of the pressure screen. It's intended to protect the oil pump gears from debris in the oil sump.

No relevant service bulletins from TCM, except SB96-4 which says the old mesh suction screens should be replaced with new perforated metal suction screens.

TCM Manual M-0 para 3-2 says:
Para 3-2 "Drain and replenish engine oil every 25 hours of operation or 4 months for engines that incorporate a reusable oil screen....Inspect oil screens and oil filter elements for contaminates at each oil change." [NOTE the dual use of singular and plural "screens"]

Para 6-4.8.2. says:
"...3. Oil Filter or Integral Screen Change
Engines covered in this manual are equipped with either a screw-on, disposable oil filter or an integral screen (Figure 6-23). Maintenance pertaining to the filter media is listed in the “Engine Inspection and Maintenance Schedule” in Section 6-2. To change disposable filters, follow the instructions in step a; for the integral screen, follow the instructions in step b.

then step B says:
"...b. If the engine is equipped with an integral oil screen (Figure 6-23), cut the safety wire from the oil screen and remove the fastening hardware. The integral screen is not disposable, rinse the integral screen with mineral spirits over filter paper to clean the media. Use a magnet to differentiate the ferrous materials from nonferrous particulate."
