Flaminia engine rebuild

[lancianut666]

Hi all
The sump is back on and the engine is the right way up so well pleased with the progress. I also manged to get the damaged dynamo on and the fan belt to check all the pulley wheels aligned so far so good. I lubed the bores with the black graphite stuff and turned the engine over a couple of times it is a bit clunky but it sounds like it is coming from the timing sprocket as this has not been tightened up yet what was satisfying was seeing the fan rotate. Still had no luck at all with the carburettor top cover as I had left it in the fridge overnight and then warmed it up with the blowlamp but to no avail. As is usual with these restorations a list of parts has written it self so we might have to start on the cylinder heads while the new parts arrive. One is the bearing in the rear of the flywheel cover that carries a short shaft to the gearbox and is very noisy even spinning it by hand so if it is running at 3000rpm plus it will be like a buzzsaw.

In the second picture down my mind creates an image of the little Y10 anxiously waiting by grandad's bedside waiting to see if the heart surgery has been successful.

At least we have made some progress, the Y10 is waiting for it's turn as it is going to get some new sills and lots of nice new parts.

Bit more done this afternoon so we have the flywheel and the rear cover on but not tightened up as we need some locking tabs for the flywheel bolts and a new bearing for the cover. I soaked the carb in the tank of doom for 99 minutes and it was a lot cleaner and very hot when it came out but those top cover screws won't budge any suggestions or will I have to drill the heads off...doable but a lot of work but with my pillar drill and a couple of nice sharp drills we should have those cheeseheads off and the carb stripped down in a day.

Do all Flaminias have the 'flywheel rear cover'?

[lancialulu]

With carbs it is best to strip them (with lots of photos and parts counts) before ultrasonically cleaning. That 3B looks like it will take a few cleaning cycles even if you get it to fit... Happy New Year!

Have you triedan impact driver on the carb screws Jim? It might just jarr them enough to move them.
Or try putting the whole carb in the freezer so it shrinks that little bit being mostly brass, it could just do the trick.

[Parisien]

Or use the 50:50 solution, apply a number of times over a few/many days, then try impact driver?

Hi Kevin
I have never ever had any success with impact drivers either destroying the bit or reducing the impact driver to scrap metal so I do not feel investing another £15 or so is the way to go...perhaps I need to by a serious one. If the cheeseheads were bolts an impact driver might persuade them out but alas. I think the hot and cold thing might work as they have a fair bit of smooth unthreaded bit in the top cover so I will go down that route next. With regards to the rear cover the cars with the shorter propshaft have the alloy rear cover like my car and a longer tail on the front of the gearbox. Earlier cars and very late cars had a split propshaft with a central bearing with a flimsy alloy cover going over the flywheel.

Was the mid- production prop arrangement not found to be ideal, hence reverting back? I assume the donut is used universally. Propshaft vibration is sometimes mentioned, so what is the starting point when refitting a replacement shaft which has not been balanced with it's associated hardware?

I notice in the workshop manual that it was the rule to mark all the flanges and joints on the transmission shaft so it all went back in as before. I think the split shaft was similar to an Aurelia but modernised a bit, why they went to the shorter shaft I don't know.

Penetrating oil left on for a while followed by localised heat treatment in the form of a soldering iron held on a screw for a short time may be enough to break any tricky corrosion bond.
If that doesn't suffice then also bringing in isolated cold treatment with a freeze spray (Hayes do one) is worth considering.
Good luck!

[lancianut666]

I like the idea of the soldering iron left on the screw head! I think a good freeze first might help.

Slotted screws benefit from a perfect fit screwdriver blade and progressive twist.
