Wastgate Maintenance:
Wastegates can be one of the most problematic parts of the turbocharging system. This is due to the fact that wastegates regulate the flow of incredibly hot and corrosive exhaust gases. Most wastegate problems are caused when the byproducts of combustion stick to the shaft on which the wastegate butterfly valve pivots. Oil-borne deposits can have the same effect, causing the wastegate to no longer open and close smoothly when commanded. Without smooth butterfly action, a wastegate may require overhaul. There are several simple inspections Quality Aircraft Accessories recommends to help prolong the life of your wastegate:
- Inspect the butterfly valve for warping
- Inspect the butterfly shaft bearing for pitting
- Inspect linkage to ensure freedom of movement
- Inspect arm to ensure freedom of movement
- Lubricate wastegate butterfly shaft
