tailshafts

[carlo rossi]

Evidently there are 6 positions to put a tailshaft together,
is there a way of telling which was the original position from the factory.
without removing it 5 times

Yes, marking it before you pulled it apart.

Otherwise, put it together and have it re-balanced.

yeh the guy up here wants $1000to balance it the other 2 said they wont touch it
and he can only go up to 3000 - 3500 rpm
when I explained he needed to go to at least 6000rpm
he thought I was mad
he said no one has a machine that can do that
This is the prob with most balances the use the wrong weights that rip off  because they only need to go up to 3000rpm where alfa uses the very flat large contact area weights because they go up to 7000rpm
So balancing is the worst thing you can do to a 116 alfa in my opinion

People have their tailshafts balanced all the time. Beninca's can do it and do it properly.

And you should only have 3 different ways you can put the 2 pieces of the tailshaft together.

Are you sure on this one?


Cheaper to send the shaft down here and get it balanced.


Anyway, I had tailshaft problems previously, more so at idle you can feel roughness in shaft etc.  As a PM, new donuts, new bearings, got referred to a tailshaft guy who balanced my assembled shaft for a very reasonable fee.  I spin mine up consistently to 7000 rpm and a few times to 7500 rpm or maybe a bit over (until I got told off badly by someone in the know), no problems.  I seemed to remember seeing big 25 mm discs as weights on my shiny new tailshaft.


You haven't say whether your tailshaft is apart or not, if not, mark it and reassemble according to marks.  Find another reasonably priced good balancer.


Good luck.

+1 for Benincas . Just goggle their transaxle  sports sedan history if you need any convincing

thanks guys will talk to beninca
as I said here they want $1000 to do it
I dont think it was an issue, but the mechanic that has taken mine out
says he wont put it back unless i get it balanced!!
I said unless you dropped it or split it without marking it should not be a problem because it wasnt that bad
he said no
so we marked it split it put new bearing and mount and I resprayed it black and told him its all done
so i hope he just puts it back
Ps the new centre mount was interesting the one that came out was offcentre or sagged over the years and the new one is centred
hopefully it all works again
I hate not doing my own work, hard to trust anyone  here
whats beninca charge
