Technical Notes

The TO4B91 turbocharger is a fixed-geometry unit designed for heavy-duty diesel applications.

Inspect the wastegate flapper valve seating for smooth movement and proper closure to maintain stable boost control. Confirm the compressor cover inlet bellmouth design matches the intake manifold requirements.
