    Quick question, was the QP3 fitted with a specific radio from the factory? or did the dealers fit whatever was available at the time?

    Thank you.

    I have a new old stock distributor cap for a Qporte 3. I owned an '84. Does anyone need a new cap?

    Hi to the QP III group ! I am struggling with electrical issues related to the Tedel 102 which was blown. I read with great interest the posts of William Abraham in 2013. His car had a blown Tedel 102 resulting from a loom faults of some kind. Then a local elctrician tracked down the underlying faults which were causing the box to blow. However William does not detail the fault in the loom it would be very useful to have this info. It William reads this message thank you for your reply ! Kind regards, Alex Camoletti (Geneva. Switzerland, 1985 4.9L auto Marrone)

    Maserati fitted a few QPs with an Australian Holden Commodore inline 6 2,8 l diesel engine all with 4-speed auto tranny.

    Am starting a rebuild on 1 or 2 1984 Quattroporte 3. Looks like hood leaks have let water into the cylinders via the carburetor throats. The water goes right through the cylinder and ends up in the crankcase oil. Of course I have stopped this from happening but now have to start engine. Starter didn't work, so I want to rotate engine manually. Other engines have a large nut holding the pulley on the front of the engine. This engine has the pulley bolted on with 4 smaller bolts. How can i rotate engine manually? Belt wrench around the pulley? Big nut welded on a flat plate that bolts to the pulley using the 4 existing bolts? Appreciate any advise.

    If all the spark plugs are out, the belt wrench will do it. The proper way would be to fabricate a plate that would bolt on to two of the pulley bolts. This might be redundant, but i would spray PB Blast or some such rust penetrant down each cylinder, especially if water has been hanging out inside the engine and cylinders.

    Good luck!

    Hi All,

    Due to an extremely gracious benefactor, I have joined the QPIII club and now own a very nice American market 1983 car. I also own a couple of vintage Cadillacs so I am used to some of the issues with waking a car back up which has not been driven on a regular basis. I have read the manuals and have gone through about half of this thread (which has been a gold mine of info!), but have yet to come across a source or solution to replacing the air filter. I have tried to find a replacement but have had no joy. I have resorted to flushing it with carb cleaner and have finally resigned myself to rebuilding it with a new paper element should there be no other alternatives.

    Any suggestions? Any points of interest or dread to welcome the new guy? By the way, I am about to take her on an inaugural drive here in an hour or so. I assume the filter will hold out until then!

    Thanks,

    Dave Burke

    My 80 uses this one. I don't know about the later cars with the box that surrounds the carburetors.

    hello All..

    I have been busy cleaning carbs as of late.. So, I thought I would post some pictures of the results...

    My 4 QPIII carbs were pretty dirty... I soaked them for 20 minutes in Carb Cleaner, rinsed them and then
    put them in my ultrasonic cleaner for 90 minutes at about 125 F, rinsed again, and then dried carefully with
    a heat gun ... I am surprised how good they all look, given they are 36 years old !

    In one of the pictures, you will see a 38 DCNL from my Mexico.. It is 50 years old, but all it got was the
    ultrasonic bath. I may soak it for 20 minutes in the carb cleaner and then do the ultrasonic thing again
    to see how it comes out before I do the others.

    Hope you like the pictures!

    I may have a diagram of the circuit, if not I'm in touch with William from time to time. PM me offlist with your email and I'll see what I can do.

    Nice work, they look great!

    Will you be replacing the throttle shaft bearings with sealed ones, or leaving them as-is?

    I upgraded my needle valves and seats with Grose-jets, and would recommend the same to other's rebuilding their carbs.

    Only source of air filters I know of in the US is MIE. There are alternatives in Europe, but don't make sense if you're in the states.

    As far as tips and tricks to a new owner, use the car! Take it out weekly, or at least bi-weekly, just for 20-30 minutes. Exercise the suspension, gearbox, and electrics (windows, sunroof if you have one, seats, etc). Things tend to fail when they aren't used, when the car just sits. There's a lot of little electrical gremlins, so keeping everything working will make your owner experience that much more enjoyable. That's my advice at least. Oh, and keep it dry. Rust is no fun.

    IIRC they were fitted with Beckers. Mine had a "Mexico" model, radio/cassette, I've seen others as well.

    Quick question - I seem to recall somewhere reading that the aircon units in the QP3 are York Borg-Warners, as installed in commercial trucks at the time, but I can't find the reference. I know an owner here who needs some help, compressor engages and clutch seems ok, system is charged, leak free and ok, fans blow, but no cold air comes out. He was thinking of going to an Italian car specialist, I was wondering if a commercial truck shop might be a better option to fix the aircon.

    Any suggestions for a reference, and for a shop or two in SoCal that know these aircon systems?

    Thanks.

    The compressor is a York, an r206 model. York compressors were used on many imported cars, both factory and dealer installed and in almost all aftermarket systems, so I think he should have no trouble getting support from any decent AC shop. There shouldn't be any need to go to a truck AC facility. Parts are still easily obtainable from companies like Four Seasons. The manual available from Ivan's site gives lots of useful detail about the system. The system looks pretty conventional except for the use of an isobaric valve - I'd never seen one until I worked on my Bora - my QP3 has it too.
    It's a good thing the clutch engages. The sheaves on the QP3 (and at least the Bora, Merak, and Kyalami) have a 60degree angle for the Gates Polyflex belts, so the Barufaldi clutch assembly might have been difficult to find.
