i've been using this method the first time i got it down to 1 thou, but i thought i should try and get better so i took it off and have tried another 2 times but now i can't get it too 1 thou at all even at the start. does this mean i have damaged the fan or collets?

I am sure the Colet's are OK, you just have to go through the process again.
You should have stopped with 1.... Anything 2 or better is excellent.

I use a little graphite grease on the lower collet, nothing on the top.
remove the fan, take the collets out and check for burrs on each surface. |

not a problem, use 1200 grit sandpaper and remove it. Just dont remove extra material or you'll make it out of round.

Does it matter whether you use a dial or a test indicator? The way the arm is on a test indicator seems like it would be easiler to setup.

Test indicator will work fine. Probably easier to use the test indicator and set it up.

In the Youtube video by Wjvail, he's using an indicator with a resolution of .0001, right. So, tell me if I have this right, if the needle didn't move at all he would have runout of .0001. But, as long as the needle stays between the 3 and the 4 in the video, he's under .oo1. Which he is in the video. Is that right?

If the needle doesn't move at all. The runout is .000000. Never seen the needle not move at all but a couple of times. I burned a gallon of fuel after that for a sacrafice to the heli gods . LOL
Less that .002 is fine for me. David |

If the needle doesn't move at all, it means that your are'n touching the fan hub....

Maxists The Baddist... You've got it completely correct. Each small division is .0001" and each "numbered" mark is a thou .001" It's a frustratingly accurate gage and a fleck of dust moves the needle about 1/2 a circle! Between 3 and 4 is .001" Bill Vail

This isn't as hard as I expected it to be. I bet I'll have a happy engine now.

How about the fan hub to clutch driver gap? How do you adjust it?

Thanks. How do I make the adjustment using the tool? I see it slides in. What do I do to fix the gap?

Put the tool between the clutch plate and fan. Shove it up untill there is no gap anymore. Then repeat on the other side. After that all you need to do is some rechecking if the other side didn't shift.

I use a .025 up to a .030 feeler gauge. I set the gap with the feeler gauge across the fan hub surface. Then push the motor against the clutch driver. I then pull the feeler gauge out. Then I check the gap at each 90 deg interval between the fan hub and clutch driver without moving {rotating) the fan and clutch. If the feeler is loose or too tight at the each 90 deg check point. I make the adjustments to correct this. Once the feeler gauge fits the same at each 90 degs. Then the clutch driver and fan hub are square to each other. Been doing it this way ever since the fan hub with dampners started to be used. I never have used the forked tool that comes with the kits. That tool is .030 thick unless it has changed.
