The dedion bushing on my '85 GTV6 is bad and I'm trying to get it replaced ASAP.

First off, does anyone know how many hours of labor this typically runs?

Second, I also have a friend who is a mechanic. He has done some minor maintenance work on the car before and I've helped out. He is willing to give replacing the dedion bushing a shot assuming I get any special tools required and detailed instructions. Will there be any special alfa tools needed on this?

Is this too complicated a job to be done by a shadetree mechanic and foolish owner?

Hey Fragmaster.
how long will it take = ????????
depends how much of the exhaust needs to be removed to lower the de-dion at the front.
Special tool makes the job easier.
Its like a round cylinder that tapers down to squash the bush so it fits in the hole.
It is done with the de-dion in the car,but some remove it and press it in with a press.= not recommended.
Use the special tool only.
Once fitted,that should be the end of it.
I put V6 de-dion bushes in 4 cyl cars as they last longer.And work better.But thats another story.
Borrow a tool,or remove the de-dion and get an expert with a tool to fit it.
If you want,I can post a pic of the tool.

Just playing with the camera so I thought I would add the pics.

Im sure this topic is elsewhere in the BB forums,but thats ok.

I'm more concerned with how many hours of labor this is typically billed at. I may just have it done by a shop if it isnt too much.

All the local alfa mechanics I've tried seem to have quite long turnaround times though.

Also, I have yet to buy a manual for the car. Wouldn't happen to have any suggestions?

Just an update,the next largest tool is like a support and bush removing tool,the other 2 are removing and replacing tools.
Guess it makes it easier and a better quality job having special tools.
Any other recommendations welcome.

It can take anywhere between 2 hrs and 4 hrs= depends who has been there b4 and made a mess of other parts. that need to be removed.
If its an isostatic gearchange,the pin in the shaft can take a while to remove if the butchers have been there.
Then the exhaust.Is it able to be half removed,or the whole exhaust removed.
Hard to quote or estimate,but 3 hrs sounds ok.

Well,that adds time to the job as the exhaust has to be removed fron the cast iron manifolds,and sometimes the studs BREAK= adds more time.

There is no need to removed the manifolds. Only the center & rear exhaust sections need to be removed, it possible to burn & cut the old bush out if you don't have the correct tool - more difficult if dedion is still attached to the car but still possible.

Inserting a poly bush is a lot easier then going with a stock rubber part and you don't have to worry about staking the new bush in place.

How do you fit a V6 bush to an alfetta gt? I was told that the V6 is bigger so it must be cut.
Is it a recommended mod?

Over the last 15 years or so,I only use V6 de-dion bushes in 4 cyl + V6 cars.
Yes,they are bigger,and tougher,and can be fitted with the special tool only.
Some people fit the V6 bush by chamfering one end and jamming it in,but using the tool makes the job perfect.
Guess many years ago,I got upset at fitting about 6 standard 4cyl bushes in my customers car.(he ended up becoming my father in-law.)
Hated stalking the top plate,and sometimes i had to weld the top plate (tacked).
Then I started seeing his daughter.
Went to her house and found that 20+ speed humps had to be driven over to get there.Speed humps that he didnt slow down for.Bushes failed(noisy).
Did some research and found that a V6 bush will fit.
Once the V6 bush was fitted to his car,4+ years later,never needed to be replaced.And his daughter married me.
Hey,There are a lot of opinions on this subject,which are most welcome.
I put V6 de-dion bushes in 4 cyl race cars and road cars and never had to replace any.
I put them in customers cars,and never replaced any.
OK,There are other bushes that can be installed (poly,,Rose joints etc),but since I have never had any problems with the V6 bush,Ill keep using them,and fitting them with the special tool(genuine Alfa tool)

This is just an opinion from an Alfa Romeo specialist that hates doing things twice.Once fitted,its forgotten about,especially the noise a worn bush creates.
More suggestions welcome.
By the way,we are never too old to learn something new or dooing something better.Im willing to always learn new things,as long as they dont cost too much.
I find the BB great reading etc,so keep the posts comming.

From the cast iron manifold.Not including the cast iron manifolds.

Robert, thanks for the advice.
I want to upgrade my 82 alfetta-gtv with poly so it seems that I should stick to the 4cyl bush. Also the Peruvian Alfa dealer from the 80s-90s closed so my mechanic, who worked on that dealer, won`t have the Alfa tool, so I guess he would use a press...

Oh,and before I forget,a washer will have to be added to the top of the de-dion bush between the bush and the support housing.
I use a washer from the front wheel bearing.The one behind the nut that tightens the wheel bearing.
The hole will have to be opened up to fit the bolt.
Once the bush is fitted properly,the job is forgotten about,and the car more enjoyable to drive.
Remember,Use the special tool to fit it.
And,I put some loctite around the bush while installing it.
Hope this subject wasnt mentioned elsewhere.
Oh well,great tying practice and use of camera.

Hey Ennio.
using a press can distort the bush on the way in.
I tried that years ago(a press) and didnt have any success.
Use the special tool.Its the only way.
The tool shrinks the bush so it fits in the hole.
Look at the special tool pic at the begining of this thread.The tool is tapered to shrink the bush for both 4cyl + V6 bushes.
