I can't put any more shims behind the cone, as I will not have enough gap left to play with.

But it looks like 1st/2nd gear spurs are spaced alittle wider than 1st/2nd gear pinions - there seems to be an excessive gap between the spur gears.

Pinions are on correctly - just to confirm, the 1st gear pinion number faces outwards, whilst the 2nd gear pinion number faces the engine.
Try turning your 2nd gear pinion around so the numbers on both face outwards, gives a slightly wider spacing on the pinions.

Also check the one way bearing is pressed in properly in 1st gear housing, have had one that wasn't quite right.......

i just checked the space between my pinions, and it does seem like M T's gap is much less. so i think you are correct he has 2nd pinion backwards. ??

Thanks guys,

Pretty sure the manual states that first pinion number faces out, and second faces inwards towards the engine. I did try having both facing out, but the thrust holder and bearing doesn't quiet fit correctly.

All fixed now. I just drilled out the engine mount alittle, which allowed me to move the engine outwards slightly more.

Cheers.

Hi to all! the last week it was the first for me with the 747 and I was really happy with it

Fast lap times and zero problems!
But now the rain is on and the game is over ...I was looking if there is some ways to make the trasmission of the car lighter..
...like lightweight 2 speed and middle shafts and so.

I hope you can help me

Thanks in advance

I modified the 2-speed flange and use titanium bolts.

I was already searching for it, took me a while.

When you print the attachment on A4 paper it should be the correct size, let me know if it isn't.
