I wnat to move my V-one S-II GS stock engine to new Tamiya chasis......


Thanks......

Did you remove the clutch nut? if not then you should use a piston locking tool and then use a four way wrench to remove the clutch nut. It should be counterclock wise to loosen the nut. Not sure which size on the wrench but it should be one of them. The shoes need to be carefully removed by taking each spring off. Be careful you don't damage either the spring or shoe. If you are using a racing clutch then it should slip off. After that the flywheel should come off with a tap of hammer. Good luck!

Thankyou jon,.....but the problem is I don't have piston locking tool, so i can't hold the shaft to remove the others,.....I already remove the shoe.....

Any idea to loosen without that tools..??

Wrap a rag or hand towl around the flywheel. Grab it with a large pair of pliers. Then use a socket to loosen the clutch nut. If I remember correctly its 10mm.

ok is this side exhaust or rear? IF it is side I used to get a piece of paper and fold it according to the space provided in the opening for the header and the shove it in there. I made sure to get it really close to being snug but not too much where it would tear off inside the mill. then I would take the clutch nut off. If the wad does tear just remove the head and be sure to see if there are any shims that come off as these are apart of your tuning. If you fail to replace these this may hinder performs. LMK!!

You can do as the previous post as well but I find this to cause pain in your hand..lol Good luck

Ok,..it's side exhaust.....

I will try it.........thanks guy's.........

You can also try a large flat plastic cable tie in the exhaust port to prevent the piston from moving. Best bet though, is to invest in a piston locking tool. They work great (and are safe) for flywheel removal.

I tried the cable tie thing and since the HPI engine I was working on had MAD compression It broke the tie. I still think you should invest in the piston locking tool. YOu can pick one up for under 9 bucks out the door.

the next safest method aside from purchasing a piston locking tool is to induce a hydrolock. fill the piston chamber with after run oil through the exhaust port. the piston will compress the ARO causing a hydrolock and prevent the crank from turning while you are removing the clutch nut. when done, remove the glowplug and drain as if it were a flooded engine.

I can get the clutch nut off by gripping the flywheel by my hand with a rag then if the flywheel won't come off I put the engine block in a vice (don't tighten it up) and use a rubber hammer to hit the side of the flywheel- it'll usually come right off.

I've had a time when the flywheel spun freely even with the clutchnut was at its tightest, you can either flip the oneway bearing of the pullstart unit and grab it with a wrench to loosen the clutchnut. Or you can fill the cylinder with afterrun oil or some other sort of oil and use an old glow plug to hydrolock the engine so you can loosen the clutchnut.

I've read that some put string in the glow plug hole. Enough to not let the piston to turn over. When done, just pull out the string.

Best way is........

Get the proper flywheel wrench like the ones from OFNA, Racer's edge, etc to remove the clutch nut and to remove flywheel with no damage just go to Wal-Mart and get a battery terminal puller....which just happens to be the perfect size for removing flywheels and it's cheap too. This is the "no damage" correct way to handle both jobs. Just my 2 cents.:thumbup:

Anything that locks the piston is going to put stress on the piston and conrod while you're "breakin' the nut".

McVickj's suggestion is the closest to what I was thinkin'... I've used slices of bicycle inner tube (which are great heavy duty rubber bands by the way) or popsicle sticks as insulators between channel-locks and flywheel while reefin' on the nut.
