I've got everything running fine now except for the 2speed..
I went by the book(as helpful as it is) and still no shifting..
right now I have the screws at four turns out..
should the second gear spin freely forward and backward? (this is before installing the engine.. )
I know the first gear has the one way bearing..
looking at the directions it looks like the set screws holding the balls in should be sunk all the way in.. mine wont go that far..
If I do it binds up the balls..
thanks for any help you have to offer.....
Adjust the set screws so that as they are tightened down, they force the two shoe halves apart by only a slight bit ( per manual ).
Then try this..
(1) pull off 1st spur gear and inspect the the clutch shoes can easliy be removed from the second gear housing. If the shoes can slip in and out you are OK. If the shoes won't come out , the adjustment screws need to be tightened more ( probably not your situation though ).
(2) install and start the engine
(3) hold the R40 by the roll bar handle and hit full throttle for about 2 -3 seconds. As the transmission shifts, you will feel the car "rock" in your hand. If its not rocking, then turn off engine and adjust the two clutch adjustment screws CCW 1/4 turn each.
(4) restart engine and hit throttle to see of it shifts.
repeat step (3) until you feel the car shift. This is only a crude method. Eventually you will need to fine-tune the shift point under car acceleration ( on the track ).
