ENGINECHECKING AND SETTING THE VALVE TIMING
Engine: RFJ
Tensioning the timing belt.
Refitting (continued).
Turn the tensioner roller (9)anti-clockwise, using a hexagonal spanner at «c».
Place the index «a»in position «e».
IMPERATIVE: The index «a» should go past the slot «f» by an angular value of 10°.
