Installation. Method 1
Parts that must be replaced:
- Timing belt,
- Timing Belt Tensioner Roller,
- Crankshaft pulley mounting bolt,
- Intake valve camshaft plug,
- Timing Belt Idler Pulley,
- Camshaft cap for exhaust valves.
The first method is used to replace any components located in the front part of the timing drive with a toothed crankshaft pulley without a key, without the need to loosen the fastening parts of one or two toothed pulleys of the camshafts.
1 - Setting the valve timing
Attention! Be sure to degrease:
- crankshaft end (from the timing drive side),
- boring and bearing surfaces of the timing belt pulley,
- bearing surfaces of the crankshaft pulley,
- camshaft ends (from the timing drive side),
- holes and bearing surfaces of the toothed pulleys of the camshafts.
This is necessary to prevent the timing drive from shifting.
This relative displacement leads to engine failure.
Position the camshaft grooves horizontally and offset downwards from the camshaft axes, using a tool to turn the camshafts if necessary.
Install:
- device (5) on the ends of the camshafts,
- lifting eye bolt (6) to secure.
Position the RENAULT logos (7) on the spokes of the camshaft toothed pulleys vertically upwards.
Install the new timing belt tension roller by inserting its protrusion into the groove (8).
Loosen the tension roller axle mounting nut.
Install:
- toothed pulley (9) of the crankshaft,
- new belt,
- new timing belt idler roller (10).
Tighten the timing belt idler pulley mounting bolt to the required torque (50 Nm) using the tool.
Using a 6 mm Allen key, align the movable pointer (11) with the recess (12) by turning the eccentric (13) clockwise.
Tighten the timing belt tension roller mounting nut to the required torque (7 Nm).
Install the fixture on the cylinder block.
Note: There are two types of lower timing belt covers:
- without a hatch for setting the valve timing,
- with a hatch for setting the valve timing.
a - Lower timing drive cover with a hatch for setting the valve timing
Install the lower timing belt cover (14).
Tighten the lower timing belt cover mounting bolts to the specified torque (12 Nm).
b - continue the installation procedure, regardless of the type of the lower timing cover
Install a new idler pulley.
Use a screwdriver (15) to make sure the flywheel does not turn (clockwise when viewed from the timing drive side), otherwise turn the engine crankshaft until it stops in the device (16) using a screwdriver; the crankshaft groove must be at the top.

Tighten the new crankshaft pulley mounting bolt to the required torque and turn it to the required angle (40 Nm + 145°±15°) (the crankshaft must touch the device).
c - Lower timing drive cover with a hatch for setting the valve timing

3 - Checking the timing belt tension
Turn the crankshaft two turns clockwise (if you look from the timing belt side) and until the previously applied marks are aligned (on the phase regulator pulley), screw the device into the hole in the cylinder block.
Slowly and smoothly bring the crankshaft to the stop in the device.
Remove the tool from the cylinder block.
Make sure that the movable pointer (17) is positioned opposite the notch (18), if this is not the case:
- loosen the tension roller mounting nut no more than one turn, holding the movable indicator with a 6 mm Allen key,
- smoothly move the movable pointer (17) until it aligns with the recess (18), turning the eccentric (19) clockwise.
Tighten the timing belt tension roller mounting nut to the specified torque (27 Nm).
4 - Checking the valve timing
Before checking the valve timing, make sure that the indicator and the tension roller notch are in the correct position.
Screw the tool into the cylinder block.
Slowly and smoothly bring the crankshaft to the stop in the device.
Install (without making any effort) camshaft locking device(the grooves on the ends of the camshafts must be in a horizontal position and offset downwards from the shaft axes).
Note: If the camshaft locking tool does not engage, the valve timing must be reset and the timing belt tension adjusted.
Remove:
- device for setting valve timing,
- from the cylinder block.
a - Lower timing drive cover with a hatch for setting the valve timing
Install the hatch cover onto the lower timing belt cover, making sure that the pin (20) fits into the recess (21).
b - Lower timing cover without valve timing adjustment hatch
Install the lower timing belt cover.
Tighten the lower timing belt cover mounting bolts to the specified torque (12 Nm).
Installation method 2
Parts that must be replaced:

- Timing Belt Tensioner Roller,
- Timing belt idler pulley,
- Crankshaft pulley,
- Camshaft toothed pulley fastening nut,
- Crankshaft pulley mounting bolt,
- Intake valve camshaft plug,
- Plug of the distribution hall of the exhaust valves.
The second procedure is used to replace any components located at the front of the timing drive with or without a keyed crankshaft sprocket that require loosening one or both camshaft sprockets when replacing.
Install the fixture onto the camshaft timing pulleys using the fixture.
Loosen the nuts (22) of all camshaft toothed pulleys.
Remove:
- device from the cylinder block,
- all nuts securing the camshaft toothed pulleys,
- toothed pulleys of camshafts.

- boring and bearing surfaces of the timing belt pulley,
- bearing surfaces of the crankshaft pulley,
- camshaft ends (from the timing drive side),
- holes and bearing surfaces of the toothed pulleys of the camshafts.
This is necessary to prevent the timing drive from shifting.
