I have an issue, I was doing my timing belts on a 360 - My vise grip holding the Cam Gears on the left bank fell off without belt on! (Right side not touched yet) - The cam gears moved position, the yellow marks are still on them, so I know they have to meet, but it is impossible to turn the cam gears by hand. What tool would you use on both to move them so the yellow mark meets so I can put the belt back on? Any help appreciated, STUCK! attached photo for reference of the gears Image Unavailable, Please Login
Iirc I used this on the cam pulley so it wouldn’t mar the teeth. Image Unavailable, Please Login Sent from my iPhone using FerrariChat
Oof. Ive always been terrified of this happening. Perhaps if you could wedge something in between the bolts on the cam gear that you would able to get leverage on and rotate. Sent from my SM-N950U using Tapatalk
Use a large pair of Channel Locks and use the old belt as a buffer, so you don’t mess up the cam gears. Sent from my iPhone using FerrariChat.com mobile app
"You are not alone". It happened to me last year on my 1st timing belt job on the 360... I think I've written a post about it back then... The intake pulley slipped a few tooth and was impossible to turn back "by hand". I slept (poorly) over it and the next day, came up with a solution. I used the old belt on the intake pulley and the crank pulley, using the wrench on the crank to turn the engine over and that was enough leverage to make it turn... Once back in place, use vice grip to hold it again. Then turn back your crank pulley to its original marks. It worked for me... Good luck...
I would say go back and do it right at this point. https://www.ferrarichat.com/forum/threads/degreeing-cams.148917/
Thank you for all the tips. Towing it now to the shop would be a diseastor ♂️ Do you think one of these in 16 inches long will work? No visegrips are made that open as much as the pulley. I would have to put something around the pulley as I tossed the old belt out. If I can put my vise grips on the pulley very so lightly so it grips but slips I can then fine tune the top and bottom pulley ?? Image Unavailable, Please Login
IF you are going to ghetto this please read post #6 and think about what this poster has written. Then put an old piece of belt to a pulley, grab the belt close to a pulley circumference and use the resulting leverage and see if you can convert the mental image into physical action. It is easy to show hard to describe.
Read my post above. This wasn’t a big deal to rotate using the crank pulley and the old belt. I would not recommend trying to grab the pulley you’re trying to bring back with anything other than the old belt. Sent from my iPhone using FerrariChat
It's not the easiest place to get access and leverage but this is how you adjust the cam timing if needed.
Pardon my ignorance, but is this the area? Inside the engine under those plate covers? This is 21mm? Image Unavailable, Please Login
I wish Aldous voice would emigrate to the colonies here..... Texas is nice chaps! We would line up our f cars around the block for your wizardry!
You might want to think about a pair of triangular wooden blocks with a through bolt or stud next time, the mole grip idea looks a bit dodgy. I have not worked on the 360 belts.
Will be working on it next week. I will be taking a video and I can post it here for the next guy who ends up in this mess. If all fails, will have to tow it to a shop, I did take video and photos of the gears and belt before I un-did the tensioner, so I'll have something to compare with. For anyone who has never done this type of work before, I suggest you just pay the $900 labor and have someone do it, a 7 hour job now is turning into a 30 hour job haha
I find that a 21mm open ended wrench has trouble turning the cam shaft because of the access to the cam shaft interferes with the fixed angle of the open ended wrench. The next time I am in this spot, I would buy a 1/2 inch, 6 pointed 21mm socket, and grind away some of the material inside the socket to fit over the round section of the cam shafts. Then I can use a 1/2 rachet to turn the cam shaft. If you can measure the diameter across the round part of the cam shaft ends, it would help the effort.
A crowsfoot socket might be a good choice. Image Unavailable, Please Login I am sure there is a nice tool that can lock in those gears. After reading this thread I will definitely purchase or fabricate prior to my next belt change. A video would be great to see. I just did the major belt service on my car and this is probably good advice for a lot of people. I probably had ~20 hours into mine but then I was working slow and trying to enjoy the process and using a lot of my tools! I have good environmental controls in my garage so often it is the nicest place to be so no rush! LOL
No it's not. It is too big to fit inside the head cavity where the cam shaft lives. I tried. And the flat parts of the cam shafts are kind of shallow which make the crow foot engagement unstable and very hard to use when you add the extension on top of the crow foot.
