They have the key to do it IF the set you have now is machined correctly. Here's how it works. If a timing set is machined DEAD ON when you install the timing set dot to dot, it would be in correctly. Modern cams are ground with the advance already in the cam. The whole reason for degreeing is to make up the difference in tolerance stacking. No one machines exactly the same. We're talking minute measurements here......degrees. Half a degree off with the camshaft......another half with the cam sprocket and another half with the crank sprocket.....and yet another with where the crankshaft keyway is. And here's the kicker. All those "half degree" amounts I mentioned.......you would be DANG LUCKY if that's all it was out. I've seen one I built years ago that wheeled in at 12 degrees retarded set dot to dot. We never wouldda known had we not put the wheel on it. So put the wheel on it.
That'll be sloppy as a ***** on payday in 15 minutes run time.
That's how the old MP manuals said to do it, if memory serves. And as RRR mentioned, degree first, then order your key.
when you're trying to keep the wobbles in the weeble an extra $50 will save you $500 down the line.
Without a degree wheel, you have no clue where it's installed.
Wow, I just lost some respect for Bullet. They must think everyone knows about degreeing a cam. Apparently not.
I have a wheel and dial indicator. How is it that I knew the lobe separation was spot on dot to dot. Bullet was awesome.
That's good to know.
Ya, I was and still am a little worried about the dependability of doing it that way but I guess that's what the bolt is for.
The lobe separation is ground into the cam and cannot be changed. You clearly have no idea about how to degree a camshaft. We're trying really hard to tell you. You need to listen.
I understand, but neither has he said he did degree it. We're just trying to help make sure he gets it right.
The LSA will read the same on every one of the 360 degrees on the wheel since it is a ground in angle and cannot be changed without re-grinding the camshaft. Good luck with it.
You are not checking lobe separation when you degree the cam. You are verifying the position of the cam relative to the crank by using intake centerline.
Have you sheared one off ? Or known someone that has?
Okay. The cam is centered with the crank according to the 12 degree lobe separation at dot to dot and needs to be advance 4 degrees. Does that wording work better for ya?
I actually do check/verify the lsa when I’m degreeing a cam in.
I have not. Like I said I just don’t trust them after looking at them. The size of the cross section of an offset key is very small and even stock valve springs, distributors, and standard volume oil pumps put a good amount of force on that key. I was trying to be helpful.
