430 Newly Converted 6 Speed Manual Potential Issues/Question

Technically you shouldn't need to get inside the gearbox for the swap. The clutch catching high is normal. The whine is fairly common, most likely from the ring and pinion.

 

Assuming I understand what you are describing correctly, that is how they did it from the factory for the 360. Here is the parts diagram.

 

The F430 had the same set-up from what I understand:

Please provide a you tube video for the sound ..maybe normal, maybe belts on alternator/ Ac or throw out bearing

Does the noise change when you push clutch in or out ..put ac on and off ?

If the dealership told you that the clutch master cyl sharing brake fluid resvoir is not an ideal situation then I would find another dealership cause they don't know what they're talking about. All factory 360 and 430 manual shift cars clutch master cylinder share the brake reservoir. A converted car can be done either way but that's another thread.

 

I converted my first f430 in 2017 exactly the same way it would have come from the factory. I never had an issue with the brakes or clutch or poor clutch pedal feel. The pedal catches towards the top as mentioned and there should be 1 inch play at the top. I Drove the car for 3 years.

 

NO. Whomever you spoke with at the dealership is an idiot and should be beaten with whatever tool is nearby. Both the brake master cylinder and the clutch master cylinder take unpressurized brake fluid from the brake reservoir and then suck it in and pressurize it down the brake line or clutch line. Completely different hydraulic lines. One goes one way.. the other a completely different direction. No effect on one another.

You might need to bleed the system with a brake bleeder. You loosen the nipple at the bleed block and pump the brake. I've even used a gentle vacuum to suck out the air in the system. The bleed nipple may fit loosely aluminum to aluminum, I've used a wind of plumbers tape to perfect the seal. To each their own.

 

My oem gated 430 clutch is definitely not stiff. Seeing how mechanical the gate looks, I assumed the clutch would be heavy, but surprisingly it really isn’t much different than my 993 or cayman.

What is different from other clutches is that pedal travel is very short, and there is not much play at top of travel. From what I understand the clutch is automatically adjusting to keep this amount of play fixed. Fwiw my gated 575 clutch behaves the same way. Hopefully the experts can shed more light if I am wrong

 

Btw, has anyone heard of a dealer doing a f1-stick conversion? Seems this is done by independent shops.

If a shortcut was taken and the thrust (aka throwout) bearing wasn't replaced, then the thrust bearing is designed to use F1 fluid instead of brake fluid. If brake fluid is fed to this thrust bearing, then the seals may prematurely fail. If the proper thrust bearing has been installed, then the brake fluid reservoir should feed the clutch too.

If the car has a new clutch, and releasing at the top may indicate that, then it's also very likely the correct thrust bearing was installed.

 

do the gearbox gear changes feel clean and crisp?

 

There are 2 ways of doing it:

One is the OEM way, which is to replace the T/O bearing with one designed for brake fluid and to run the clutch line from the clutch master cylinder, which is connected to the brake master cylinder.

The second is to use a clutch master cylinder NOT connected to the brake system and to keep F1 fluid (ATF) to actuate the clutch. You can buy clutch master cylinders that accept ATF/F1 fluid for pretty cheap. This prevents you from needing to change the T/O bearing, which makes the conversion process much simpler mechanically as you only need to add a clutch pedal/clutch master cyl, shift turret/cables, and change the outside gearbox controls.

 

Then there's the third way where the original thrust bearing is left in place and routed to the brake reservoir. This is the incorrect way. Still a way though. I suspect that many cars that are being converted are taking the shortcut. It would be impossible to tell from an inspection and if purchased from a dealer, they'll just shrug their shoulders when asked such a question. There's a lot of room for shenanigans in the conversion process.

 

Sounds like throwout bearing to me

 

+1 throw out bearing .. normally they make the noise with clutch released not pushed

 

@beasters Who converted the car? Where was it purchased? Did the previous owner opt for a throw out bearing replacement or a seal rebuild?

 

Something's telling me the car wasn't converted correctly. And no don't drive the car

 

That sound is the Pilot Bearing.
