306 hdi crank shaft pulley
Im pretty certain the crank shaft pulley needs replacing on my tin topas ive had a look and its all sloppy and loose and started making a grinding
type noise couple of days ago. Ive only got tomorrow to fix it, if i cant find a garage that can fit me in, whats involved? One garage said the
cambelt pulley can slip if you dont do it right, surely it would be on splines though? Aparrently its a common problem at this age, anyone else
experienced it? Thanks

I've done one on a T reg 306 HDi a while back, not a lot to the job really. The auxillary belt is the pain the backside, I cant just remember
how I moved the sprung tensioner for it back, I'm pretty sure there was a ceratin tool/technique for it. Mabye something with an 8mm square
drive they use for sump plugs or something you got a spanner on from behind the alternator?
Make a drawing of the route the belt runs to save remembering it & mabye getting it wrong.
The crank pulley bolt can be a bit of a bugger but sticking it in 5th gear & getting someone to hold the brake on is usually enough or a decent
impact gun.
the pulley should just come off once the bolt is out leaving the cambelt sprocket behind on the crank & I'm fairly sure it's keyed to
the crank. Done loads of cambelts on the older XUD which is very similar & the cambelt sprocket moving has never been a problem.

The crankshaft pulley on a 306 HDI has a rubber pulsation damper built into it.
When the rubber of that damper breaks up then it will display the symptoms you describe.
No alternative but to replace it with another, and they aren't cheap. My son had one replaced with a good second hand one (from a written off
car) and the Pug specialist recommended welding it up to make it last longer.
