Hi all,

I was putting in a Centerline driveshaft guibo kit and found that one of the split bearings (or whatever you call them) had broken and come apart. It is a piece attached to the front of the rear driveshaft that gets inserted into the rear of the front driveshaft for alignment. It is the exterior potion that is split and goes on the outside of a doughnut shaped nub. It looks like a ball bearing outer race. I'll try to attach some pics. Nothing else looks to marred up which is a pleasant surprise, so I don't think I need the whole thing.

Could someone please help me to find one, either new or used. There is a big beer in it for you! And probably cash...and women...or men. And I'll say thank you.

Attached is an exploded diagram of, I think, an earlier shaft. It is similar to number 35.


Thank you in advance.

I'm not absolutely certain it's the part you're looking for but if you go to Highwood Alfa's website,click on "116/75Mech parts"; then click on "Propshaft", the item you need is at the bottom of the page, identified as "propshaft alignment bush". It costs 17.50 pounds. Highwood is the best source I've found for Alfetta & GTV6 parts.

Hi Jim,
Thanks for that! I think that is what I need. Their picture could be better but the description is good so what else could it be.
Thanks for letting me know that Highwood is good for GTV6 stuff. I’m new to this model.
Where should I send your beer and swag? 🤡

Centerline stocked that bearing last I checked, but they don't list it on their website. It really should be part of that kit as this bearing is quite commonly worn. It's a fairly standard sized bearing but there are two versions of it as used by Alfa. The one I saw from Centerline worked perfectly.

For the bearing, it was part number FD810 from Centerline, if you get someone on the phone. There are many items that Centerline does not list online unfortunately. Frustrating, but hopefully you find a source that works for you. I am a big fan of Highwood, they pay attention to the details on these types of things.

Thanks Rob.
I didn't know that Centerline didn't have all their items listed. I plugged that number into the search and nothing came up. I'll call them to see if they have it, if I go that route.
That is a bit frustrating that it is not listed or suggested. That advice from a specialist is valued in saving time and now the extra freight too. Ah well.

Agreed!

If they don't have it, you might be able to cross reference a "generic" bearing that will work. I just don't have one loose here to measure conveniently. Do you have dimensions? Some of the generic ones are narrower on the outer race but work fine in my experience.

NOTE: your photo shows that the INNER RACE of the bearing is still stuck on your propshaft. You'll need to remove that.

The bearing on my drive shaft (1984 GTV6) has an outer diameter of 22mm, width is 11mm and wall thickness is 2.5mm. FYI, I measured the bearing installed on the ball.

I haven’t measured it but those measurements sound like what I have.

I emailed Highwood with a list today and hopefully they have it.

I’ll make sure to pull off the little doughnut on the shaft as you mention.

Thanks for the help!
