More 355 Belt service questions

Do a search for posts by CHAA. 101 uses for a pair of lock grips.

CHAA, hope you come back here dude... we need you.

 

1. no cams must be degreed. You can fashion a cam locking tool easily from bits and peices you probably have lying around the shop.
2. Use the Cavis belt tension gauge, or a steager gauge, spec is in the service manual.
3.yes you can reuse the crank bolt. Use the recommend thread locker in the service manual or LocTight blue
4. Check everything!! and replace as needed. Thow a new t-state in there aswell.

Yeah,

If you still have the stock exhaust manifolds send them out to get ceramic coated.

 

It appears someone stated no need to time the cams if locked in place, unless I missread the response. 355 in particular are very sensitive to the camshaft timing. Idle quality, emissions and premature catalyst and manifold failure will all likely occure if it is off even slightly. the cam timing should be +- 1 deg. from specs. spend your time doing it the first time or you will be replacing other parts and taking the engine out to perform the service again and correct the timing.

Best of luck.

 

I assume you are refering to my post. I forgot the comma after the word "no". In other words..."No, the cams MUST be degreed"

 

This is interesting because I just spoke with the local Ferrari dealer and they never degree the cams when changing a timing belt.

They also stated that you would know if the cam timing were off because the car would not idle smoothly.

They will check if the customer insists but this is extra cost.

My car has been dealer serviced from day one ......they checked my service history and they advised against degreeing the cams (not necessary).

Also, they also advised that for warranty reasons their policy is not to alter the factory cam timing.....so from their point of view if you service your car at the dealer then the timing is dead on as set by the factory.

I decided to speak with an independant ex ferrari mechanic I know and he confirmed the same story. Its a corporate policy.

Now I guess if you service your car at the independants then you really can't be sure what someone has done or what a customer has requested be done.

 

BLASPHEMY! BLASPHEMY! Arrest the heretic.

Somebody stop rifledriver from reading that.

LOL

 

Unreal! I guess that's why we find that a majority of cars that come to us from the dealer are NOT timed "dead on."

And I guess that's why we find that a majority of cars that come to us from RECOGNIZED independent shops ARE timed plus or minus 1 degree (dead on, in my book).

When I started, I didn't check or set cam timing because I didn't know how and didn't take the time to learn. Then, I had a guy work with me that showed me how. Now, we do it a majority of the time. I guess that's why people say "it's never run that good since I've had it..." after one of our services. That's also why I don't do "a la carte" belt services, either.

Jeez, "extra cost" from the dealer to do the job RIGHT?!?!?!?

Can't wait until Brian or Dave see this...
