So i dropped off wee "Aria" (that's what the mrs named my alfa 147) to the garage and they don't have the part to replace the variator, neither do the Alfa specialists in the area!

I have sourced one since, however, when doing so I found links for "Variator shell bearings" and a "variator relief kit, with springs" are these things also necessary in the replacement or should I keep and refurb the existing ones?

Thanks in advance guys.

Was the variator rattling at startup? - If so, a new one is needed.

I know some people have had success with the repair kits, but I think they're widely regarded as a temporary measure.

I'd repaired one in the past, which wasn't rattling, just thought it worth doing whilst I had the belt changed, but sold the car shortly after, no idea how long it lasted.

The variator is mounted to the cam pulley by 4 cap bolts, and a thread into the camshaft - I don't know what the torque is from memory - someone will have an elearn which covers this I'm sure.

I remember the variator should be loctited in place though

Are you sure it didn't just need an oil change?

The variator gets a bit noisy when the oil is thin and old. An oil change used to shut mine up .. and that went 210K miles!!

Once I started to do the oil changes myself, and knew what oil was going in, it never "complained" again .. ( first three years, serviced by Alfa dealer!! Chattered more that once when they looked after it, but I was also averaging 20K a year!).

Yeah. She's an old car though and I'm getting the engine fully serviced and all parts replaced so I figured should get that done too.

But I'll get everything done. It's an mot centre and the guys are solid.

Also, thanks for you response too bud, appreciated.

I must admit I've never bothered with torque settings and just go with feel.

The variator shells are large and they are not under much load and I've never felt the need to change them even up to 200k. I wouldn't be overly concerned. I don't remember even using thread lock for the variator. I've never had any issues and I can put big miles on cars.

Getting it off is harder .. holding the cam in something without damaging the lobes ..

I bet if you try a search there are posts on this forum about removing/refitting.

lightly nipped up in a bench vice using the old cambelt between it and the jaws worked for me.

If you're replacing the variator as a whole, a big pair of water pump pliers removed mine, if it's to be refitted, you need the tool - although one can be fabricated easily enough.

I have one in the garage if anyone needs?
