Hi I am having the exact same problem with pulleys, I was replacing them on the rear only to notice that the original 'side' pulley should have a longer conical nose on it. If you replace it with one of the pulleys 503197 then it does not sit against the bearing and then there is too much end float on the layshaft! I have an aluminium pulley (aluminum if your reading this outside of the UK!) but this pulley is narrower.
Anybody got any coment on how to overcome this, a spacer maybe?

Also:
a/ I have heard that replacing the 17t pulleys with 18t reduces belt slip is this the reason for using 18t?
b/ Do I replace have to replace all 4 off pulleys or can I just replace the centre pulleys (the 18t packet 503222 has 2 off identical pulleys so I have the same problem as menioned above i.e. they are both the same in the packet and the layshaft is sloppy so I just want to replace the centre pulleys and leave the original 17t pulleys for the long belt)
c/ Does using 18t pulleys affect the internal ratio of the car?

Any help here would be most appreciated!


Regards,
Steve

Doesn't the new 2009 version of the E4 address a lot of these issues? I think I read about it on Redrc.net nd it was linked to Team Magic's site.

It would appear that the exploded view listed against the '09 car just shows the same old pulleys and does not differentiate between the side pulley and the centre pulley ref PDF link below which was posted on the TM website last year but has it listed against the '09 car

I think I shall use ligthweigh 17t pulleys in the centre and Aluminium on the sides to over come this problem as I need yo sort it out before Sundays racing!

I think my E4 will make a great T/A.

Mine like a 94/43. I have a good balance between acceleration and top end and the motor comes off around 120 to 130.

Aren't you allowed to gear it 4.2 final?
