Title: 1.0 AAU cam pulley same as 1.3 PY pulley?
Post by: POLOMON on July 19, 2012, 11:11:01 am

Hi All,
 As title really, ive had a search about on here and all i keep finding is the information on charger pulleys. Nothing seems to be about for the cam pulleys.
 I do not have a G40 item to compare tooth profiles so thought i'd ask on here :-)


 Thanks chaps,
Ben

yes they're the same.

the only difference between cam pullies is that older ones had square teeth and newer ones (most stuff J plate onwards) had round teeth.  So the different teeth need different cam belts and the bottom pulley needs to match too.  Most mk3 stuff will be round tooth

Thanks Hayesey, i ask as mine was a J reg you see, i knew it was a funny age for the change over so for you to say that cleared it up. As long as i have a round tooth AAU puley all is well.

 Thanks alot, can sort out getting an adjustable item made now :-)
