Refit the screw (10).
Turn the crankshaft to bring the camshaft towards its pegging point.
Peg the camshaft at «c», using tool [2]
(oil the pegs).
WARNING: Do not press or damage the track of the engine speed sensor target (13).
Peg the crankshaft at «e», using tool [3].
Remove:
- The timing belt protector (13).
- The engine speed sensor (14).
Slacken the screw (15)of the tensioner roller, and keep it slackened using an allen
spanner at «d».
Detension the timing belt by pivoting the tensioner roller
(clockwise).
Remove the timing belt, starting with the coolant pump pinion.
Checks.
ESSENTIAL: Just prior to refitting, proceed to the checks as below.
Check:
- That the rollers and the coolant pump pulley turn freely
(without play and without tight spot).
- That there are no signs of oil leaks (at the crankshaft and camshaft seals).
- That there are no leaks of coolant fluid (at the coolant pump).
- That the track of the engine speed sensor target (15)is not damaged or scratched.
Replace any components that are defective
(if necessary).
