My dream is to share what I have learned working on my 1975 308 GT4. I am working on a book "Ferrari Service for Dummies or What I Learned on the Internet" If you find any mistakes please let me know and I will revise it. As most of you may or may not know, I decided 11 years ago that I wanted to do my own work as I loved my car so much I couldn't trust anyone to touch my precious Ferrari. I started on the original Ferrarilist.com and met many members who guided me along the way, many are here now also. I also had help from several experienced Ferrari mechanics whose names will be withheld as not to embarrass them with my acquaintance! I am also on several other Ferrari lists, as I am a nut and have all this free time when I am not working 10 hours a day! :-) I hope you enjoy what I have written and I can help some other poor soul who was as lost as I was 12 years ago. Please give me feedback, as I am in the slow process of becoming an amateur Ferrari mechanic! Respectfully, Rob (Robertone) Garven (This article was originally published here on Ferrarichat.com)
Tools and or supplies needed:
1. (5) Quarts suitable oil (Swepco 201 80W-90, Agip Rotra LSX SAE 75W-90, Redline 75W-90) Oil needs to have a friction additive for the clutches in the differential! (Jonathan's note: Many people including me have had excellent results with Redline 75W-90 NS).
2. 10mm & 12mm allen hex wrench
3. 19mm & 22mm open end wrench
4. Suitable drain receptacle to catch and recycle oil
5. Rags or towels to wipe up spills etc.
6. Funnel and a piece of hose approximately 10 inches long.
1. 1 creeper
2. 1 large piece of card board (To catch any oil that may splash.)
3. 1 box of latex gloves
4. 1 shop apron
Note: Never get under your car supported only by jacks. I have done this personally but I love my car more than myself. If you do this, make sure you have a good insurance policy. Your family will thank you, and at you memorial I will tell them I warned you in advance and try to buy parts off your car!
1. Make sure all work is done on a level and clean surface, you are sober and at least someone is around, (in shouting distance) in case you have an emergency. Get all the supplies you need ready at hand.
2. Raise car to a suitable height or use a lift, make sure the car is stable and even. If you use jack stands make sure that they are placed so that they will not get in the way of your drain receptacle and are more importantly placed on the main tube frame in the appropriate locations.
3. Remove the battery ground cable. I have a green spin off knob that disconnects the battery ground cable and is very handy, not only when working on the car but when leaving it for an extended period of time as not to drain your battery. Note: I have never had any battery drain even when the car has set for over a month, some models have more drain and even need a trickle charger to keep them charged for as little as two weeks! Jonathan's note: I never disconnect the battery to change the gear oil, but be careful not to short the starter motor to ground!
4. Loosen the 22mm transfer case fill plug first, because if you drain the transfer case and can't get the fill plug off, well you get the idea! (See below)
