RE: V6 rebuild questions

["Jeff Greenfield" <alfaguy@xxxxxxxxxx>]

Bill -

I just finished a V6 rebuild (2.5 Milano).

The only lock tabs on the main journals are on the rear most two. All the
others use a second thinner nut on top of the regular nut. The lock tabs for
the rear main journal are NLA from Alfa, so you will need improvise.

It's possible that these were eliminated on the later cars, check with your
favorite parts purveyor who had the factory parts catalogs.

There is no bushing in the back of the crankshaft on a V6. There is one in
the engine flywheel. I'd clean out all the old dried grease replace it with
some fresh grease. Other than that, just bolt it all back together.

There is a piece on the front of the driveshaft that fits into the flywheel.
This is held to the driveshaft with a retaining ring, so there is no need to
disturb any of it. I don't recall if there is a machined bushing in the
flywheel that this fits into, or if it just fits into a machined hole in the
flywheel.

HTH,

Jeff

Subject: V6 rebuild questions

Hey everyone, I'm rebuilding my 3.0 V6 and have two quick questions.
First, I see in the manual that there should be safety tabs under the
bolts that hold down the crank bearing caps. But there were no safety
tabs when I removed the bearing caps. Do I need the safety tabs - or was
this something phased out by 1988 when my milano was built?

Second question, when I removed my crankshaft I did not see any "bushing
for direct drive shaft." I do see something that fits that description on
the end of my driveshaft. Do I need to replace this thing? Is it ok if I
leave it on the end of the drive shaft and just install the driveshaft
"the reverse of removal"?

I have received quite a bit of help on this engine rebuild via email from
several alfisti. Thank you very much. If I can get my crankshaft back
from the machine shop by this weekend, then I might be able to get the
engine built and broken in just in time to get the car down to MAARC'S
VIR school in September. Ofcourse that's where the engine failed last
year (broken tensioner, Turn 1, lots of blue smoke, painful memories).
Wish me luck.
