Default fly weights

So the flyweights get the addes weight from the M3x4 set screw, and sit on the pins? or in between ?

I think the most important thing about the thrust bearing is to make sure that step 8.7 on page 28 of the manual to put shims to minimise end play is followed. Next make sure the thrust bearing is installed correctly. Inner ring (5.0 mm) first towards the clutch shoes followed by the bigger one (5.2 mm).

If you use the Mugen Super Grease, you would not need to grease it often. I have not greased mine about a month of racing and it still works plenty fine. You can still see grease sticking to the balls of the inner ring.
I think where I went wrong was with the "minimal end play" bit and not using Mugen Grease. I thought I'd only left a small amount of endplay, but then when I read Glenn's article and he mentioned between something like 0.1mm and 0.05mm I saw that my endplay was too much. Now I can push and pull the bell and I see only a small amount of movement.

Cheers, Mark.

Cheers, Mark.
Yes Hudy is coming in a couple of weeks with a new set-up set that will fit the 710 corectly a simple mod. for the upper plate.

Anyway, the skies held up yesterday and it was overcast ! Pretty cooling to play in the afternoon.

My apologies to rub it in Mark, Sow&Steady and the rest but today is going to be another beautiful day !
Man ... its already 10:30am and it looks like the forecast is right ... its very cloudy and now drizzling.

Maybe I should go ahead and start the rebuilding.

And if you don't have a temp gun will the spit method sizzle?

Only kidding ... what temp can I expect to see for an overheating clutch Motorman?

Hi Motorman,

Will you please send me more information about your 'Red Rulon shoe' ? And the Mugen hard spring?

I would like more descriptions, part numbers, availability... that sort of thing.

Also, may I put some of the information from your post in my Centax-3 article on myTSN?

Regards,

Would anyone care to comment on this question, please?
I too am curious. Some people say 'cut flyweights' and others say 'weighted flyweights'... to me cut flyweights can mean a few different things.

there are several methods on the flyweights, cutting the tips gives them less centrifical force as they get lighter so the engine must spin up more to overcome the spring and engage the clutch. this is good and bad. its good because you can get some more low end punch, but because the force is lower as engine torwue rises the clutch starts slipping as the shoe cannot hold the clamp on the bell tight enough.
Weighting the shoes by drilling the tips and adding set screws gives them more centrifical force with also gives more punch but if the spring tension is not increased the engine will always bog off the corner. with the stock spring it is to light and you cannot get it to tighten up enough before the spring actually bottoms out hence you cannot get rid of the bog and the clutch will phusically not travel far enough to bit the bell correctly causing slip once again. This is why you need to go to higher rate spring so it can be adjusted tight enough to give you low end punch with weighted flyweights and not coil bind before the shoe actually contacts the bell. Centax 3 clutches are so small their centrifical force is low so they become very critical on setup.

If the clutch bell turns blue its overheating, you should try to stay below 400 degrees the plastic flyweights will start to melt soon after that. Also remember that the clutch transfers a serious amount of heat into the nose of the engine. Many times the engine is blamed when it stalls during a heat race on a pit stop even though it ran qualifiers all day with no tuning problems. if the clutch over heats the nose of the crank the engine vaporlocks causing it to stall. This is why its so hard to restart an overheated engine as the fuel hits the inlet of the crank and vaporizes. usually the front of the engine is hotter than the head because of the clutch.

Glen the spring PN's are
Mugen H0767 Silver Super hard
Mugen H0764 Medium
The Rulon is the Same material as the Delta type shoes being made for other cars

I switch between both from time to time.

My 2 cents
heavy flyweights and spring GOOD
light flyweights and soft spring BAD

does any of this make sense or have I done a poor job of wording it?
