Sorry for the basic question but this has been baking my head all afternoon. Current belts are as below:
A - 6283MC - which I believe is a Gates belt (thanks to the always helpful Brickwerks team), and thus 10x638 - so, wrong.
B - 10 x 625 currently - pretty slack (well over the 5mm spec) but no idea how old - but also possibly the wrong belt as well?
Alternator is the 65amp as far as I know. No PAS. So I think that A needs to be replaced with a 10 x 600 and the Alt dropped down a bit accordingly, but what should B be replaced with? If it's the 10 x 643 that is on the BW site, is that going to be very slack, or is there enough adjustment in the shims to sort that?
Thanks.
