1996 Ferrari 456 GT engine dissemble help

Can a mod please move this thread to the 456 forum so this gentleman can receive the help he needs.

 

@Aerosurfer any idea?

 

Hey Kyle,

Saw your post on the FB group too..

Lots of good info on this forum, you are in the right place.

Those lower drive gears need a ringnut tool to remove in order to get the front cover off.

Are you the shop doing the work or the owner? Lots of good research and tutorials if you are doing the work.

I havent gone this deep on mine yet, so better heads than mine can hopefully help

 

I am interested in the same subject, particularly in methods / tools required to remove timing covers. Has any further info been offered?

 

You can bump it with air gun if you can get it in place. You would need to put the belts back on...

I could not as I have a larger aftermarket radiator with less clearance so I had to remove the cam with gear on, grip it in a vice with the old belt and bump away.

You will need to remove the cams to replace the seals anyway right?

Putting the gears back on and torquing them is a bit controversial. Search "matchbook."

I ended up doing that method as well as something a little different.

 

Removing the timing covers is not hard although you will need to break the rtv seal if its been done that way. I lightly tapped mine with a rubber mallet to loosen it up

Just make sure you get all the bolts out. There is one bolt that holds the rear cam sensor cover to the cam cover that is easy to overlook.

Its the bolt hole to the right of #22.

You should make a video

 

I am curious of your methods. How did you get the gear off, then back on and retorqued?

 

That is the "matchbook method." It works. I have also seen someone hold a spanner pronged wrench in the timing holes while someone else tightens the bolt. Looks to easy to screw that up. Another guy used a metal washer between the cam gears and clamped them together with vice grips. I think I might be ok with the latter if it was a solid copper washer or copper wedge. I use a copper penny (I forget the cut-off mint year) to wedge a motor cycle primary gear solid. That always worked great.

The 2.7 motronic section is missing from the 456GT WSM, so I use the one from the 348/355 link below. Codes and setup are pretty much the same except we have 6/12 cylinders rather than 4/8. Remember Ferrari built this thing as two 6 cylinder motors welded together so you have two separate 6 cylinder fuel management systems.
