Installation Notes

Replacing an ejector housing requires attention to detail to ensure the vacuum system functions correctly. Follow these professional steps:

1. Clear the Passageways: Before installing the new VG1238110133, inspect the connecting pipes for carbon buildup or sludge. A blocked pipe will render even a new ejector housing useless.

2. Verify Gasket Integrity: Always use a new seal or gasket when mounting the housing. Even a tiny air leak at the flange will disrupt the vacuum effect required for the system to work.

3. Check for Casting Debris: Although our parts are pre-inspected, always give the internal bore a quick wipe with a clean cloth to ensure no shipping debris obstructs the narrow venturi passage.

4. Hand-Start All Bolts: To avoid cross-threading into the aluminum engine block or manifold, always start the mounting bolts by hand before applying final torque.

5. Final Vacuum Test: Once installed, start the engine and use a diagnostic gauge (if available) to verify that the negative pressure at the crankcase is within Sinotruk’s factory specifications.
