Well, I took the belts off to do the heads. The rad is close true enough.

As far as Ferrari timing belts go it's not that bad the actual timing belts are rather straight forward, you will need to remove some bits to gain access and as conaero pointed out this is where it can becoming very time consuming.
That said 456,550,575 aren't bad, 612 is a very very time consuming as in those everything needs to come out

can you cut the old belt in half ( along the length of course!) and slip on the new one. Cut across the old one and discard, pushing new one full into place. This was oft repeated technique on Fiat Coupe 20VT , where access was tight. (Sold car before it was due, but would have tried this)
Clearly one to try on "someone else's car" first. Assuming the pulleys do not have any flange then surely it is same job. As long as belts are identical the timing remains unchanged.

Only one way to do the job and that's the way the manufacturer has laid out the procedure.

Yeah never do a cam-belt like that, if you're not skilled enough to time the belt > do not < touch it
That said the actual timing part on a F116/133 is straight forward.
I can't really understand the need to cut corners on these cars, it's so common lately people trying to cut corners on maintenance etc.
these cars will bite you in-time if you start cutting corners and once they bite it's expensive (and i'm not only talking about bent valves, skimping on items in the ignition, seals, etc etc etc it always will surface as a issue)

I have always treated both mine to no expense spared services and often some preventative measures too. Basically, anything that gets flagged gets done, no discussion.
Yes it’s costly, but I tend to keep my cars for a long time and strongly believe it will all equal out in time. To me at least, it’s a comforting feeling driving a car where absolutely everything is spot on and everything has been taken care off, particularly as I do put hard miles on them.
Evening,
£300 of not very much !!!
The Hill bearings are cheaper than the Ferrari ones but still £95 plus Vat is excessive for a bearing.
Lambo painting will take a back seat as i have the Ghibli Diff to look at and then this cambelt.
Not sure when i will start this but car hasnt moved in months so i had better look sharp. It will be 5 years since the last one and about 7500 miles, i dont believe the belt will have fallen apart and the bearings were not leaking last time.
My cunning plan was to .....
Find TDC
Check the tension on the belt using the Gates App. If i test it 10 times and get an average reading, i will look to set the belt to that tension once fitted. These cars are now 25 years old and i reckon the app on a brand new phone will be more sophisticated than 25 year old belt tensioner technology.
Lock the cams - bought a couple of twin cam locking tools.
Swap the belts and bearings.
Put it all back together and turn it over couple of times and then pray....
Will post pictures as i go,

Fair point.
"From the 575M WSM, the frequency when the longest span is struck is 126 hz. ", taken from Ferrarichat. I have the manual upstairs.
it was set last time by Foskers, i would be confident that it was set right. I was working on checking as a way to check the tool accuracy. I managed to use it to get the alternator tension and that has worked ok.

You only get it wrong once......
Reading about Ducatis last night, they seem happy using the Gates or Continental App to check tension on cam belts. Less expense when it goes wrong, but they will rev higher and get worked harder.
If I get stuck Foskers is only 15 mins up the road, will just get the car taken there.

The benefits of WFH !!
Removed undertray, coolant hoses, air boxes and most of the belt covers.
The airboxes were a nightmare involving lost spanners and bloodied knuckles, the bolts are underneath the box with little access at all. Perhaps through the wheel arch is easier but taking wheels off on a four post lift is hassle.
Foskers did it last time and there are some handy yellow marks on the pullies !

Not in the US......
The internet is awash with opinion and counter opinion on this, it is almost like a "which oil" thread.
Uk states 3 years, the US state 5, it is the same engine and same belt.
Mine was last done in 2017, the car hasnt moved for the last few months. I changed oil filters, air filters, fuel filters and transaxle oil. I am happy to call it 5 years !!
After 5 years and 4000 miles the belts haven't snapped and the engine hasn't blown up. I need to use it more often !!!
The risk is always that if they do snap, it costs an awful lot more than the actual change, a bit of scaremongering and revenue generation by Ferrari ?

I’ve always religiously had the timing belts replaced every 3 years on the 360, but I did do a lot of mileage (I’m on 180,000 km now)
I’m due another belt change this year and given how easy the access is on a 360, and my recent engine refurbishment, I probably will change them.
I do take your point though.
