2.4D (2005 on) V70 D5 (D5244T5) Cambelt Split on startup

[Veedubmad]

Hi,

I'm looking for some advice on possible damages caused by the cambelt splitting on my Volvo V70 D5 engine.

I have started stripping the engine in preparation for replacing the cam belt and have found that the aux drive belt which drives the air con (small belt) has snapped and lodged its self within the cam belt area causing it to split almost the full length of the belt but not snapping the belt.

I have turned the crank clockwise until the timing marks line up on the cam sprocket and cam belt cover and would appreciate and info on what the orientation of the crank pulley should be so I have an initial indication of whether the belt has slipped a tooth or more and whether it is worth replacing the belt and progressing the rebuild.

I have pics to show my findings but am struggling to up load them!

Thanks

With the cam marks lined up, the crank pulley should be like this with the 4 bolts in a regular square shape and the locating pin at the 12 o'clock position.



For more detail about the specific crank timing mark aligning with a casting on the oil pump housing, click on my signature and scroll down the list of videos to my D5 Cambelt Change Video.

Hi yes I have watched that video of the cambelt change a few times and very useful I thought.

I'm pretty sure mine is the Euro 4 engine MY2008/9 and wondered (hoping) if the alignment of the crank pulley was the same as the older models ?

If I get chance, I'll check Vida but I'm pretty sure that all D5 crank pulleys orientate like my picture when the cam mark is aligned correctly.

Youre lucky it snapped on startup and not driving and it just split in half with some grip left
Even if it slipped a tooth it could be fine, you could try to rotate the crank pulley back gently while locking the campulley in the correct place. if there is resistance stop
If thats possible and than replace the belts correctly according to that video and see what happens at startup.
If there is damage you will notice

Hi,

Don't suppose you managed to have a look on VIDA regarding the crank and camshaft orientation did you ?

Thanks

I have a Haynes manual but by the looks of the pictures it refers to the euro3 engine and not the Euro4!

Haynes is fine for timing pin locations as the Euro 3 and 4 block is the same.

The compression test is available on Vida but you also need an extra DC power source to keep the Dice awake during cranking.

I sell Dice and Vida for £100 delivered.
Mine are all tested and known working, unlike the ones on eBay, Alibaba etc.
