engine problems
 

Hi
i just bought a 3 shoe-clutch from ebay, and i have installed it on my force .21 engine. When i start my car the engine revs very high but it doen't want to take off. do you know what could be wrong with it

RE: engine problems
 

First off does the clutch bell and spur gear just sit and not move?
If yes then take a pucture with the clutch bell off if you can

If they are moving the problem is elsewhere, outdrive set screw posibly

RE: engine problems
 

the clutch bell does move. sorry i can't get any pictures cause my camera is not working sorry.

RE: engine problems
 

well if the bell and spur are turning your problemis in the drive train somewhere,,like i said before check all the diff set screws,,what kinda car is it?

RE: engine problems
 

this is all assuming that you have re-mounted the engine correctly and ensured that the bell is the correct distance from the gearbox? Is it???

RE: engine problems
 

the car is a kyosho inferno 7.5 sport and yes the distance is fine cause the lhs meshed it for me this is a orginal picture of my car last year with none of the hop-ups on it and i have a picture of my engine from my lhs it is off my lhs web site.

RE: engine problems
 

Did you have the same problem and that's why you changed the clutch shoes??
Ckeck the set/grub screws that hold the outdrvie cups @ the front and rear gear boxes,,this is a very common thing to come loose on RTRs,,,loctite all these screws too

RE: engine problems
 

i changed the clutch shoes because they were plastic, my original metal clutch broke so i put plastic and they were melting the grub screws are fine and i loctited them to

check the flywheel nut as well

Hold the (4) wheels stationary by pushing down on the car and see if the spur gear will turn. It should NOT turn without it trying to move the car. If it does turn freely when you are holding the tires then it is either an outdrive screw loose or a diff gear(s) is/are blown. Have you taken the center diff out yet to check it ? Hold the spur gear and turn 1 outdrive and the opposite end should counter rotate. If it doesn't......blown diff gear(s).

when i hold down the 4 tyres it dosen't move. i haven't takin out the centre diff yet, it did counter rotate.
hey guys don't worry about it any more i will just go down to my lhs and see if they know what is wrong with it. thanks alot for your help i will let u all know what is wrong with it when i get it fixed again thanks alot for your help.
