360 Cam Belts Change

Thanks Steve

 

Lots of time and effort went into your procedure. Very much appreciate your having shared this with the community.

Fine Job!

Many Thanks,
Vincenzo

 

Added to the DIY section.

 

Appreciate the feedback. I hope to improve the draft with input from those who give it a try.


BTW: Thanks to F-Chatter "sailingmagnus" for his technical insight and hands-on assistance during the entire ordeal.

 

Robert- Thanks.

 

Does anyone have more pictures of 3207? I think I can make this for a fraction of the price.

 

+1

Should be easy to make... pix please someone

 

I cut up a cheap 944 flywheel holder, rewelded the teeth section to a bar, two holes for mounting, works great.

 

my point exactly.

i was thinking more in the line of a plate, with two nuts welded to it, and bolts through the nuts. Adjust the bolts to engage the clutch or flywheel.

Estimated cost: 5$ (really Zero, cause I have the stuff needed)
Estimated time to fabricate: 30mins.....
Pleasure of doing it myself and avoiding paying OVERINFLATED Ferrari / Lambo Tax prices : Priceless

 

Good idea.

 

Made a simple locking plate that bolts in place of the clutch inspection plate (blue tape is holding the socket head bolts for easy keeping)

I believe that the Hill Engineering tool is designed to react against the clutch plate, while the tool shown reacts against a tooth (or teeth) on the flywheel. Wondering if Hill was trying to avoid that with their design?

 

I wonder more why they would like to hold the clutch plate rather than the Flywheel? any reason for this?

Regardless, its easy to make either way, my plan was to make it to engage the clutch as originally intended.

 

The might not want to stress the teeth on the flywheel. A load path through the flywheel might produce higher stress than a load through the clutch plate, due to stress concentration at the root of the gear teeth.

 

From Daniel Pass at Ricambi. Turns out 3207 is actually a univesal crank lock that works on most cambelt Ferraris.

Or only 550 and 360?

 

Remi- Turns out Brian Crall says it will not work on the 550, either. For that you need tool 3546-1.

 

cheers

 

I've attached an updated spreadsheet and procedure. (Corrected some errors in the procedure, added pictures, corrected some typos, added more links, etc.)


If anyone in the U.S., Canada, or Italy plans to perform this task in the near future, and would like someone to lend a hand (and perhaps some tools), let me know.

Been busy with my 430 lately, will do the belt job when time permits...

 

Glad to see you mention Aircraft Spruce. For those who don't know, these folks have been selling stuff to the experimental aircraft homebuilder crowd forever. They are a great source for all kinds of hard-to-source material but the big advantage is that they sell in small quantities. Need a few square feet of high tech thermal insulating material or three feet of streamlined high strength steel tubing? Aircraft Spruce is the place to get it.

I've built a few homebuilt aircraft in my time and it would be hard to imagine doing it without this company to supply components. Check them out if you're a fiddler.

+1. GREAT source for interesting parts.

ONe day.. one day.. I'll have that Sonerai I in the barn built.

 

Yes, exactly.

I'm tired of suppliers asking me “How many 50 gallon drums of gear oil do you want to order?”

BTW: I've also had good luck with Pilots HQ; good prices, small quantities:
Dow Corning Molykote 55 Oring Grease 5.3oz - DC 55

 

Ok so I decided to do my belts, and i'm in deep. Just finished removing the 36mm bolt from the main pulley. My question is how do you remove the main crank pulley? Do I need a special tool, there is not enough room for my 6" pulley puller. Help.

 

I haven't done this but........

Swear at it?
Apply heat and see if you can loosen it that way?
Tap with a AV-3040-Special-Tool (a Hammer)?
Get a different puller?
Wait for someone like Black who's actually done it to come back to you!

Where there's a will there's a way.


P.S. Pics and a DIY thread or it didn't happen!!!
