'79 Alfetta Flex Disc Part Numbers

I was merging onto the freeway the other night in 3rd gear in my California í79 Alfetta Sprint Veloce. Just as I was about to shift into 4th, I heard a loud bang (so loud it scared me) as if something hit the floor or the driveline. Iím pretty sure I didnít run over anything. I drove home ok but now there is a very slight vibration in the driveline.

I got under the car and the rear flex disc has a few small surface cracks in it, nothing all the way through. The other flex discs look ok. The driveshaft bearing support looks okay.

I found the Alfa part number 11608 15044 02 on my CarDisc. I have found that this part number, 60725177, might be the same flex disc but I am also seeing 60521631, which seems widely available.

Does anyone have insight into these part numbers?

Thanks.

I rotated the driveshaft and saw that on the other side of the flex disc, a chunk is missing between two bolts on the yoke. So that explains that.

11608 part ID is the old Alfa parts system. After the 86 Fiat takeover Alfa switched to the 605... and 607.. Somewhere if you dig you can find a cross-reference table. As for replacing your part you're in luck. Donuts for 1979 Alfettas are the easiest to find. My suggestion is that you contact your favorite Alfa parts supplier(centerline,alfa parts,highwood, EBspares,DiFatta,etc.) and ask for a rear flex disc for a 79. They should all have it in stock. If you want to be absolutely certain about the ID send the vendor a photo of your old one. If your Alfetta was a 75 or a 76 then your search gets slightly more difficult. Since you're going to have to yank the entire driveshaft it might be a good time to replace all 3 flex discs

EB Spares in England is the only place I found one. Well, except for the good used one I got from APES. That part is discontinued. With shipping from England, figure about $150.

Difatta Brothers called me today. Call them quick and it will be shipped right over.

Thanks, Jim and Slowcreek for the help.

I was asking for the part number because I saw this eBay item number: 183853822239 and couldn't figure out if it fit my Alfetta. I talked to the seller and his part number is 60521631.

I called Jon Norman at Alfa Parts and he has one but he didn't have the bearing.

Slowcreek, I called Di Fatta Brothers this morning and they're supposed to get one in Monday. I ordered all three of them.

Thanks, again.

Chances are the one from Difatta, which was originally ordered for me, will be the one that fits.

I don't think using the later model one, even with it's bushing, is gonna work.

Keep us in the loop.

I've had nothing but good things to say about dealing with OKP in Germany. www.okp.de

I've owned several 78-79 alfetta sedans and now have a 76 Alfetta GT. No parts stores in the US are really carrying Alfetta parts due to lack of interest in the US. Very understandable from a business point of view. However in Europe, Alfettas, GT and sedans are very popular and parts are plentiful.

For around $1200, I just bought all the "not in stock" parts for the Alfetta. All three donuts, clutch, bottom radiator hose, transmission mounts, bottom A arm bushings,and a full set of poly bushings for Alfetta (made in Australia).


I highly recommend OKP for Alfetta and 116 parts. The other US suppliers are good for spiders and GTV's, the more popular Alfa's.

New Flex Disc has a nick in it

I ended ordering all three flex discs from Di Fatta Brothers. The new rear flex disc has this little chip out of it. Would this be an issue?



Extra large size version

Thanks, again.

I'm not sure.

But, let's see the other side of it.

Hey Leslie

I wouldn't worry about it. It's the thick side bits that carry the engine torque. The small bit of rubber that's missing from your guibo wasn't going to hold anything in place, it was just there to make the rubber casting easier.

Looks like a used giubo to me. It should be ok but some of its life is already gone.

I don't think so because there are no washer marks on the through tubes.

The extra rubber on the metal is just from the casting mold. Nothing to worry about. Be sure to put some quality grease in the inside of that bushing if it doesn't have some. While you have the drive shaft out make sure the center support is in good shape. This whole shaft front to back rotates at engine speed, so everything has to be in line and in good condition. If everything is good, your good to go for 40,000+ miles.
