Checking the technical condition of the belt must be carried out at every maintenance of the car.

The term for replacing the belt, regardless of the state of its 60 thousand kilometers or four calendar years, whichever comes first.

A broken belt can lead to major engine repairs. Engine pistons and valves can be severely damaged.

The valves either break or bend, and the pistons collapse. The connecting rods are also damaged.

When examining the belt, you need to pay attention so that there are no cracks, cuts, delamination. The belt surface must be free of oil traces.

On F4R and K4M engines, the pulleys do not have alignment marks, so you need to have special tools for setting the camshafts to the TDC position of the first cylinder and a special pin to fix the crankshaft at the TDC of the first cylinder.

The fixtures can of course be made by yourself according to the drawings given in this article.

We prepare the car for the task. We install it on a lift or a viewing ditch.

We remove the right support of the power unit for this:

We substitute a jack under the oil pan through a wooden or rubber block.

We set the crankshaft and camshafts in the position of the top dead center of the first cylinder. To do this, unscrew all the candles.

We screw the bolt of the accessory drive pulley into place by installing a set of suitable washers.

To determine the position of the camshafts, it is necessary to remove the plugs from the holes in the left end of the cylinder head.

We turn the crankshaft clockwise, the grooves on the ends of the camshafts should take a horizontal position, and are displaced downward relative to the axes of the camshafts

To fix the camshafts in this position, you can make a device from a metal plate five millimeters thick.

The dimensions of the fixture are shown in the figure.

Проверка и замена ремня ГРМ автомобиля Renault Duster

We install the device in the grooves of the shafts

We check whether the crankshaft is in the TDC position of the pistons of the 1st and 4th cylinders. For this:

Проверка и замена ремня ГРМ автомобиля Renault DusterПроверка и замена ремня ГРМ автомобиля Renault Duster

Unscrew the plug with the E14 head

Insert the locating pin into the hole (shown with the pallet removed)

When the crankshaft is in the TDC position of the pistons of the 1st and 4th cylinders, the locating pin 1 must screw into the hole to the end of the thread and rest against the milled area 2 on the crankshaft cheek.

After that, the crankshaft cannot be cranked.

If, when screwing in the adjusting pin, it rests, and the end of the adjusting nut on the pin does not come into contact with the end of the hole boss in the cylinder block (there will be a gap between the nut and the boss), then you need to turn the crankshaft slightly (removing the device from the camshaft grooves) the crankshaft counterclockwise arrows.

Then you need to screw the locating pin into the cylinder block hole to the end (until the ends of the pin nut and the hole boss in the block come into contact) and turn the crankshaft clockwise until the shaft cheek pad stops in the pin.

We install the device for fixing the camshafts, if it was removed.

An M10 bolt can be used as a locating pin
