I didn't know that. I always thought that the 512BB's engine had to be pulled for the 30K. Thanks for the info. |

All 512 TR's have to come out the top. There is no subframe like the TR. I was told that they went back to the solid frame for strenth and less weight. And by the way, a BB512 belt change can be done in the car by just pulling the gas tanks. |

Just wondering Tom(FerrariOldMan) does the engine not drop out the bottom of that car? I've done numerous Testarossa's and I've always dropped the rear engine subframe out of the car...seems much easier than fighting to get it out the top. But I guess if you don't have a hoist,you have know other choice. Seems odd they would go back to the old bb512 way of removing it from the top. |

While you are there Jim I would recommend rebuilding the clutch slave cylinder (the seals have been known to swell and cause sticky clutches) and replacing the clutch shaft seal as well as the rear main as you mentioned. May also be a good time to replace the shifter shaft seal at the trans. Check the axle flange seals too. Pulling the motor is a little tricky. As you pull it out, it also has to be tilted so I would recommend a screw type equlizer device (Harbor Freight has a good one)as part of your lifting harness. I have pulled about 4 or 5 of these and as long as you take your time you will be Ok. |

You're right, tom, the shop manual presumes an intimate knowledge of ferrari service procedures. Somewhere, someone must have written this down. If not, maybe I'll be the first, and you can all read about it "as it goes down".
My clutch "chatters" and the pedal is kinda stiff compared to other lesser mile 512's. The rear main seal leaks oil and will need to be replaced, so... while it is out, why not rebuild the clutch too. So far on this car I've had to totally dismantle the dash and interior and re-wire everything the cheap "Stereo-rama" installer hacked up in 1994. Would you believe 3 fuses in one line? Hot wires dangling beneath the dash? 1" holes cut in the firewall with no grommets? And worst of all (dare I say it?) CRIMP CONNECTORS!!! These people have no shame. |

Is there anyone out there thats done a major service on a 512TR?? I hav'nt managed to find one! The earlier TR is quite different, I think the waterpump has been improved on later 512TR's so may not need replacing, owners in the US are much luckier than those in the UK! theres no feedback from owners over here at all! Will keep watching the site for info', many thanks for your time, Barry Castle London UK. |

Dont rush the job either. take your time. replace any and every low pressure hose that is suspect. believe me, you dont want to have to go back in there after you've already done it once. I am also planning my major service this winter.

The shop manual doesn't even give you a "how to" for a 30K service. About the only thing that you will have to go by is you 30K check list in your maintainance manual. If you are replacing cam belts, the engine will have to be removed. This is not a task for the faint of heart for it has to be lifted out the top using a very sturdy hoist. As for ordering parts, I would go ahead and pull it out, examine everything first then make your list and order your parts. Water pumps are rebuilt not replaced in the TR's. Usually the oil seal is what goes bad in the pumps. But replacing this will entail replacing the coolant seal and inner race for the oil seal too. Clutch? Is it bad? If it ain't broke, don't fix it. But if you do want to replace it, go back with a stock unit. Less headaches. And don't forget to service the rest of the chassis. Not just the engine. Good luck. |

I am planning a 30K major service on the engine/clutch of my '94 512TR in the next 6 months. At home. I've rebuilt domestic engines before, and I'll have experienced people nearby (a former Ferrari Formula One mechanic) when I get stuck, but is there any literature that outlines the step-by-step procedures (Ferrari Repair for Dummies?) involved with this model?
What parts (hoses, shims, belts, etc) should I order? Change the water pump or rebuild? What about the clutch - stock replacement or upgrade/rebuild, and where? Thanks for the help.
