Cambelt Change HDi 90

Post by Blubayou »

Hi all,

Just changed my cambelt today using EvilTwin's most excellent guide.

Used an FAI kit along with a Goodyear Gator Aux belt. Just took my time & it all went swimmingly. Just a couple of observations:

You really do need that 10mm ratchet spanner, the belt covers are difficult!

One of the first things I did was to make sure I could get the crank pulley bolt out. I used the starter motor cranking method to get it out. It was unbelievably tight all the way out.

On refitting it's meant to be torqued to 50nm + 60 deg. No way! I managed 10 deg no matter how I tried. My torque wrench only goes to 100nm and it was tighter than that. Anyway, I may recheck it soon for piece of mind. I thought later I should have marked the pulley to nut location up with some yellow paint so I could do an easy visual check.

I left the pulley off from then on & refiitted the RH roadwheel to use to rotate the crank for timing etc.. which was easy to do.

Removing the starter motor was easier after unbolting & easing the clutch slave down and was really needed to see what was going on with the timing.

I used Jasper5's tensioning method & also checked the tension using a borrowed frequency tester which measures the twang of the belt. The original belt was 30hz, the new one tensioned up as in the write up 36hz, a good result for the given method I feel.

I used an 8mm allen key with two opposite peaks ground down to make a squareish tensioner adjuster which worked really well (I can get odd allen keys free luckilly!)

All done at 97015 miles.

Many thanks to the contributors on this excellent forum. :D

How long did it take and did you replace the water pump and tensioner?

Hi p1lyp,

Did it in the afternoon, guessing aroung 6 hours including tea etc.

I didn't do the water pump or pulley as they are all good.

Cam belt kit came with tensioner & idler pulley so I changed these.

The aux pulleys are also crucial but they were all ok.
