348 quiz' - what is this??

Hi all 348 owners

First I would like to let you how much I love my 348, I have had her for about 3 months now and I'm starting to learn how to handle it, and I just love EVERY meter we drive together
Now...I do have a couple of questions for you here which I hope you could help me with:

1: I found these two behind a panel behind the seats in the coupe, and I cant find any info of it in the manual - I do belive it has something to do with the fuel system (see pics)

2: Does anyone of you have a blue-print of the entire clutch for the 348?? (or a drawing)

3: I know the F355 and the 360 rims fit the 348, is there any other models in the Ferrari family which fits the 348??

4: I would like to have a Tubi on my 348 in the future, does anyone know where I can get that?? (prefer Europe, but US is ok) and how much will it cost(ca price) Is it smart to buy a used/second hand Tubi set????

5: Does anyone have a pic of a red 348 with RED calipers???

6: The intakes in the doors are mounted with 3 screws, is this correct?? or is there more screws on the inside of the door????
Is it safe to remove the door intake for cleaning???

7: Last quiz, on the top of the engine there is a little black plastic cap (on the "bridge" between the blocks, what is that??

Thanx in advance.

Paul.

LOL.

You found the brains of the engine. Those are the Motronic ECU's.

 

Could you be a bit more spesific please??

 

1: As I said before those are the ECUs or Electronic Control Units. They control the engine. In short, if you unplug them the engine WILL NOT RUN. One ecu controls banks 1-4 of the engine, and the other controls banks 5-8 of the engine. Everything for the engine is control by these.

2: Don't have that.

3: Others that I have seen on 348's are 360 BBS challege, 512tr, 550 & 575 modular rims.

4: I'm sure one of our sponsors can get you one.

5: That I don't but you may find them in the showroom.

6: There are four allen screws that hold the door strakes in place. You don't have to remove them, just open the door for easier access to the inside, from the back side.

7: It just covers the the return spring for intake compesation valve located inside the plenum.

 

Hi Paul,

Your car probably has a twin plate clutch here is a dwg..

On item #6, removing the air intake strakes on the doors:

There are indeed four allen head screws on the outside of the door that have to be removed, but there are also two nuts on studs on the leading edge of the panel, that are accessed from inside the door jamb.

The strake/intake panel is easy to remove and reinstall, but you have to be careful when reinstalling, because the front edge of the strake panel comes very, very close to the rear edge of the front fender when you open and close the door. If you install the strake panel too far forward, it hits the fender when you open the door, and you can damage the panel or take a chip off the paint.

 

Hi Chris and thanx a lot for the blue print - great.

When you buy a new clutch, what is included from this pic?? everything?? apart from # 16 the house.

 

Thanx for the VERY needful info Jeff really appreciated it

 

@Jeff
Great looking 348 you have, I'm a sucker for white cars too....
How many miles/KM do you have on her????
Have you replaced the clutch yet???

I think I need to replace the clutch soon, when the engine and gearbox is hot/warmed up, I only get RPM's and not so much power to the wheels when I "step on it" - is this a normal sign for a worn clutch???

If you have any pix with the door panel off, please post them!!

Paul

 

Unfortunately not. All you will get is the friction(6+7) and pressure plate(10). It is possible only to replace the pressure plates IF the pressure plate (10) is good. Plates are about £200GB each. It is also possible (some people have done this) to have the plates re-built - this can save a lot of money I guess.

If your clutch is slipping now I would suggest getting it replaced as soon as possible, or you may damage the flywheel (2) surface beyond a re-grind. New flywheels are expensive.

 

OK, so the flywheel can live for another round, good to know..but I belive the bearing(1) is VERY important that I replace when I replace the clutch!?
My clutch was replaced at 60K - and now it has 86K KM, the car is not "jumping" or ...hmmm....hard to explain in english....when I use it, I only get more RPM's and less "grunch" if you know what I mean!
How long (in KM) does a clutch last (NORMAL driving)???

 

PS: Come to think of it, the flywheel on my car was replaced last time the clutch was replaced (60K KM)

 

Paul: To answer your questions in post #9:

My 1990 348 now has 51,000 miles on it.

Yes, I have replaced the clutch (single disc). I took it apart once to replace the clutch, and once to repack the flywheel (did all of the work myself).

I know I have pictures of my 348 with the inner and outer door panels removed (in threads about repairing the wiring connectors in the door jamb), but I'm not on my own computer until the weekend, so I don't have access to my stored pictures right now. Sorry.

 

It sounds like your clutch is slipping, and may be a sign that you need to repack your flywheel with grease. If the grease inside the flywheel gets on the clutch is will cause what you are explaining.

 

Yes, here you go.

A friend of mine also told me this

 

Chris.

Check this out:
Today I had to pick up a clutch (I'm a truck driver) from a company here in Oslo which I should deliver to a customer, and guess what - these guys rebuild clutches - and I asked the owner if this is a smart investment, and he told me that the clutch will be 100% new again.
He also told me that he had a Ferrari in a couple of years ago, and there was no problem to rebuild those discs.
The price for rebuild 2 discs was about 130 USD, and it will take 2 days.

The clutch I picked up was looking brand new, exelent job done - I also asked the customer I delivered the clutch to if he was happy with this kinda stuff, and he said that they used this company alot, they saved many many 1000 bucks a year on rebuilding,(truck/crane company) he also told me that those guys were pros.....but alot of people dont know about this stuff and they ending up buying new clutches
So this was new for me too
Thanx alot Chris for the hint, you really made my day

Paul

 

Cheers Paul. That sure is a coincidence.

If you give them the thickness specification when you send them the plates they can make sure the dimensions are correct. This is from the manual (the specs are different if your car has a single plate).

I would avoid any disassembly of the car, like the intakes, for cleaning purposes. You can buy various cleaning brushes or even a toothbrush for tight crevis areas. The risk of something getting bent, dented or chipped far out weigh the last bit of dirt you may be gaining access to.

 

Thanx alot again Chris

BTW I do have twin plates
