Product Details

Overview

VAC-2 Inverted Oil Pickup.

The VAC-2 provides a direct replacement for the Lycoming vacuum pump pad adapter. Precision CNC machined from solid billet aluminum, its unique design offers both a standard vacuum pump pad adapter AND provision for inverted oil pickup. The vacuum pump pad is often used for one of our spline-driven alternators, such as the SD8 or SD20.

Aircraft with oil systems using the standard "T" fitting on the firewall will typically experience a 3 to 5 second drop into the yellow oil pressure range after rolling inverted. However with the VAC-2 installed, the oil pressure will have a momentary blip or wiggle on the oil pressure gauge as the ball valve switches ends. As a result, the engine receives better lubrication and prop surges are lessened.

The VAC-2 comes complete with oil seal installed, gaskets, and an MS20822-10D 90 degree fitting. Just slip the vacuum pump gear and washer in the VAC-2, and it is ready for installation on the engine. The standard Lycoming vacuum pump gear and washer will fit into the VAC-2 (gear and washer not included).
