Hi all!
Hope someone can help as nothing found on forums and Google seems to help...

2001 reg 2.8 jtd
no AC
engine no 3304976

Went to replace cambelt.
tensioner bearing shattered as it was released. All spacers went flying out in a pile. Tensioner block arm snapped.

so new cambelt kit, tensioner arm, spring tensioner.

and I'm not sure what order spacer parts go back in.

according to a diagram in webstudy and other online sources:
New bearing slid onto tensioner arm, with the long engine stud through it all.
Then shouldered washer. shoulder to bearing.
large washer.
Cover goes on and secured with spring washer and 17mm nut.

Like shown below

Now...

Original belt is 151 teeth.
After 2 attempts motor factors supplied the correct kit... apparently.

When the belt is on and tensioner is released at centre nut (21) and top bolt of the bracket (4), belt is very slack above the tensioner on turning the engine by hand clockwise.

Spring tensioner (3) in fully out. But I can easily pull the belt off by hand!

I'm guessing the tensioner is not assembled correctly, as it only gives a few mm adjustment.

Thanks in advance for your help.

In case anyone ever reads this thread while having a similar issue.......I zoomed in on Val's picture of genuine parts.....belt fiat number 99456476
Search of that number comes back 152 teeth.

Cheers all

152 teeth as on my 2.8jtd. Like Val, I did not count the teeth, but I did match the old and replacement belts together, with snowpaked timing marks on both. Subsequently marked old belt every ten teeth.
