Ferrari Mailing List: Re: 1981 308 GTSi: disaster avoided, but still in need of serious help.

Michel,

I'm worried you might have more work ahead of you than you want. If you want to replace bearing #31, that's not a big deal, although you'll have to pull that ball bearing out somehow (it is not a sealed bearing, as I recall). To replace bearing #30 on the other hand, you need to remove the timing cover. The proper procedure for this is to pull the  motor and separate the gearbox from the engine, etc. With Ric Rainbolt supervising/doing a lot of the work, I did it a different way. If you study the diagrams, you cannot pull that timing cover off easily -- there are nuts on studs holding the timing cover on as you face the front of the motor. The problem is, there are two (or three?) more studs that go into the actual timing cover from below, from inside the crankcase. These are the studs that the oil pickup tube fasten to. You'll have to drop the engine pan (pull the dipstick and dipstick tube out first), and then you'll see the oil pickup tube. You'll remove that, and then you have the studs to remove. There is no space in there. What you may be thinking is just put some sort of stud puller in there and take them out, but you can't fit that there. I had to double-nut them out. I hope I never ever ever have to do that job again.

As I said in my previous email, I asked my mechanic to change the belts. Now he is stuck because of a major problem.

Once the belts were out, he noticed the REAR BELT was so worned out, 3/4” of rubber was left on it. I forgot to check how large a new one is. The difference is huge. It was rubbing seriously on the pulley I guess. He touched the 2 “DRIVE GEAR FOR CAMSHAFT AND OIL PUMP” #27 (the one at the back of the engine) on TAV 8 in my parts manual is loose. I’d say it’s moving about less than 1/16”. The one at the front is very tight.

He knows/thinks he has to change the BEARING ON BACK COVER #30 TAV 8, but does not know how to do it. Everything is too tight.

I don’t want to miss out on the meeting at Mont-Tremblant on july 23rd -27th.

Please, please, please help us!
