Any engine builders know what this is going to be used for?

Yep. I have been wanting something like this for a long while. It is such a chore to get the cam gears off sometimes & since we are doing it on every motor now I thought it was a good idea.

Yes sure is good idea.I worry about bending the cam when doing this.Blocks would be safer than softjaws in vice.Hey and you said I wouldnt guess it right

My original idea was to have two milled halves with half of the cam profile in each piece. But , my ever efficient machinist came up with this idea and it allows future cam profile changes. I didn't think you would guess it so easy, so you are one up on me. I just dropped my latest idea on him and he is game to something a little more challenging. What do you guys think should be the next item we have made? I am trying to think of something that we have an issue with or can be improved. I don't know if we can top the flywheel idea though.....

C27, do you have the specs on the press plate you are using to seperate the crank & rod assemblies with? I think I am going to get him to make me one as well. I know it is a piece of flat stock with a deep "U" cut in it but I need the width and depth dimensions.

Is it easier/better to start with one side or the other? Might be a factor if you only need to replace the bearing. And, I assume you guys are just using a socket or the like to push the rod pin out of the crank half?

I've got one or two that need attention, but I want to pull them apart and see the damage before sending them off.

Who's been pressing them back together and what kind of jig is used for that? If you want to claim the info is proprietary, no problem with that. I'm sure pressing them back together is just about an art. I assume that's a pretty finite process- there aren't any keyways or alignment methods for the crank halves are there?

Neil,

The cranks are pressed back together and then put in a set of "V" blocks to check for alignment and then pressed or hammered into position in a circular motion. I had a pic somewhere of the guy at Crankworks doing one, I'll have to see if I can find it. You could always just send it to whoever apart to change the bearing or rod. That way you could let them put it back together. Remember there is a passaway with the freeze plug that has to be cleaned as well.
