How does that work anyway? Why would you want to adjust to anywhere other than right on "Zero?" Also, if you're building an engine and you stick it on, how do you know the pointer is accurate?!?!?!

You find TDC...then you use the pointer to make it match the balancer markings.

Or you can go the other way.

Here is the raw material for an old school adjustable pointer:

:p:p:p:p I actually have a pointer on my engine already so I know where it is, but it's solid, and it sticks out so far that you can't really see the mark on the balancer. So I was looking at pointers and I just thought to myself "How the fuck does that work?!?!"

Like Mark said,

The pointer on a stock cover may read it's at TDC when really it could be off a few degrees or so. Or your aftermarket cover might not have a pointer at all. So you have to find ACTUAL TDC for the engine, with a dial indicator and a degree wheel, then you set your pointer to read true zero, therefor when you make timing changes you know what the timing is ACTUALLY set at versus what the stock pointer might read it as.

when the pointer is rigid mounted..

then when the actual TDC location is wrong...
there is no mannor to correct it back to zero.

many dampeners are off a couple of degrees...

the only mannor to positively know where actual tdc is..is to dead stop the top of piston...and then mark dampener under the pointer.

then rotate opposite direction to dead stop again...then mark dampener again...

...actual tdc is mid way in between the two marks...

when the pointer is off...then adjust it...

we often do the dead stop test five times to be certain ......as many as it takes to be positive..over and over again..

I DONT KNOW WHAT THE WIRE COAT HANGAR WIRE IS FOR....


ALL THAT I use it for is to cut the largest piece of crap in to two pieces so that it will flush down the toilet a little easier...

Cool thanks 69RS. I might get me one of those and see where I'm at with TDC.

What is the typical degree difference between the two ways you spin the motor? Is 2-4 typical or is it less/more?

Its depends on how far in you put it. 10* is what I try to just for the math of it. :rolleyes:
