Cam Belt Tensioner Pulley Replacement

At last we have the engine back from the engineering shop, and if it goes as well as it looks we will be beating some more elises this year, anyway I digress.
We have been advised to change the tensioner pulleys, so ordered just the pulleys from Justsuds (quick service £15 each plus postage) as the whole tensioner arms although available to special order from Alfa are over £50 each.
Question is how do you get the old pulley off and new one on ? Looks like it is a interference fit of pin into arm so push out with press swap and back on again. Its not covered in the manual and not something you want to fall off so if anybody knows that would be appreciated.
Will post some pic's of the engine as we get into it.

Not that i've done it myself but I don't think it's too tricky using a suitable bearing puller to pull the old pulley off.

Re: Cam Belt Tensioner Pulley Replacement

Had the same problem when I was doing my 16V tensioners. Pressed it out using a vice and suitable sockets and drifts/bolts. Put back to together with something called "Loctite bearing lock" to "glue" the bearing holder back in place.
When you take it apart originally you can see something like this is done from the factory.

Re: Cam Belt Tensioner Pulley Replacement

My friend 'Suds' got me a 'Gates' set from his local motor factors including 2 belts & 2 tensioners for £55 inc vat.
I wasn't brave enough to change the bearings on such a critical part in case I didn't get it right.

Re: Cam Belt Tensioner Pulley Replacement

£55 is pretty good as I'm sure I paid over £20 just for a pair of belts.

Is 'suds' local motor factor a chain (like motosave, or bullseye (the latter nothing to do with darts honest)), or just a local buisness as I'd fancy a set for that price.

Re: Cam Belt Tensioner Pulley Replacement

Thanks for all the advise guys, we were on the right track , but like Dave A we have left them with the engineering shop in the end as he has a press and a vested interest with his name going on the side of the car soon. (OK we bottled it!)
Think 'Gates' is a brand of belt / pulley manufacturer as our new belts are from Gates.
Gearbox just waiting for a bush now so will hopefully be ready for when the engine is done, need to book the rolling road!

Thats right.

The belts are made by the Gates Rubber Company an OE supplier
