6. Replacing camshaft bushings
The surfaces of the bushings must have no sign of
seizing or scoring, replace them if they do.

of the bushings. If it is above the tolerance value,
replace the bushings.
To disassemble and reassemble the bushings of the
camshaft, use the drift:
- 2296187, for the F2B engine;
- 296188, for the F3A engine.
