Steve,
Sorry about the typo. You're correct about the .17 pints. As for the TR, I cannot say that this method works. I haven't seen the connection either. Best to use the "old way" until proven otherwise. Thanks for the response.

Thanks for all the help. I put in about 4 ounces. Since I learned it overflows into the gear housing, I don't think an extra ounce will hurt anything since I probably spilled an ounce trying to pump in the 4 quarts. I took her for a spin tonight and was throughly impressed with the improvement in gear change smoothness. I also removed about a quart of oil from the engine and checked after my drive. It was right on the money.
Thanks again. |

Bill B. -- two questions:
1. I know that you are correct for 308/328 (and the original question was about a 308) that it's impossible to overfill the transfer gear reservoir since it overflows into the main gearbox reservoir (and the shortcut you suggest is a useful technique for 308s), but are all Ferrari models this way? I don't see any physical connection between the two reservoirs on the TR cross-section drawings so I've been more careful about filling each reservoir separately on my TR -- are they completey separate on a TR?
2. Isn't the transfer gear reservoir capacity .17 pints not 1.7 pints? (I hope no one with a TR has tried to put 17 pints in since both the '89 and '91 US TR OM seem to have this misprint).
TIA
Donny -- just for reference, I usually need to put in only about 13 quarts for an oil and filter change even though the "dry" specification is 16.4 quarts. |

Regarding the 1.7 pints of fluid for the transfer gears, a shortcut is available which assures the correct quantity of lubricant for these "step-down gears". This uses a passage between the transfer gear housing and transaxle. As oil is admitted through the transfer case filler hole, it fills the case up to the level of the tube and then spills into the transaxle. This allows both to be filled to the proper level at once. Pour the oil into the transfer case filler, and when it flows out the transaxle filler hole on the rear of the case, both levels are correct.
The engine oil level given in the manual is the spec used for a dry engine at the time of assembly. As some oil remains during a drain, the refill will be lower than published.

The amount for the transfer case ( the 12mm hex nut on top ) is not critical as long as you do put at least what is specified.
Any extra will drain back into the main gearbox sump. The rest is just as Bret indicated. Fill until it comes out the hole ( make sure car is level). As far as engine sump goes, run the car, check when oil is hot 5 minutes after shutdown and adjust levels acordingly. |

What clutch housing are you talking about? It doesn't have a hydraulic clutch and it is a dryplate. Unfortunately I'm at school right now so I don't have all my books (or my car for that matter) so I can't check it out, damn college. If I remember correctly though the transfer case is what takes the .17 pints. The transfer case, gearbox, and limited slip diff are connected so make sure you get a synthetic oil that is limited slip compatible (Amsoil, Redline, Mobil 1 are the major ones). Make sure the car is level. You just take out the plug for the gearbox/diff (on the back end of it, near the exhaust pipes, not the one on the bottom that says olio cambio, that one is what you use to drain the system before you go to refill) then you pull the plug for the transfer case (on the top front side of it near the starter). Just pour in the oil (I think it takes 80W-90, but I put in 75W-90 Amsoil and it is great, next I'm gonna try the same weight but Mobil 1) into the transfer case plug and when it starts to come out the gearbox/diff plug you have put in enough. I know my description is a little rambling here (sorry) but you'll see when you get under there. Just pour in the top of the transfer case until it comes out the back of the gearbox/differential. I think mine took somewhere around 4 qts of oil.
My 85 (the same as your 84) has 6 quarts as minimum, 8 as maximum (so when the level is at the min line of the dipstick it has 6 qts in it, 8 at max on dipstick). It's a 10 quart reservoir system, so you could technically put in 10 quarts before overflowing but you wouldn't want to run it like that...
Good Luck, it is really easy to change the fluids, you wont have any problem with it, it's just the first time is a little tricky I guess, just take your time.
When I get home this weekend I'll post here (if someone else doesn't) what the fluid levels are from the quattrovalvole manual. |

I just bought my 308 and am in the process of changing all the fluids. I am now changing the clutch housing fluid. The manual call for .17 pints. Is this accutate and if so how critical is getting in exactly 2.72 oz? Would 3-4 oz cause damage. I'm assuming you don't use the fill-till-it-comes-out method. Could someone include their fill technique?
A related oil question. The manual claims the engine to have a capacity of 10 liters. I changed the filter and put in 9 quarts. I checked it and found it to be high. I drained a quart and rechecked. It was closer to the max line but still high. How much is typical with a filter change. I'm guessing some oil remains trapped making up the difference.
Thanks for the help. |
