bottom pulley size

[tommy8252]

Can someone clear this up for me,

I recently fitted twin 40s to my 1.3 Sr engine, I fitted it with the alternator lowering bracket, extended alternator slider and smaller fan belt.

Unfortunately the fan belt is still too big despite it being the same belt I ran on my e16se on 40s.

Are there 2 different bottom pulley sizes?

It's the early 1.3 with the bolt on metal timing belt cover.

Thanks in advance, tom.

Had the same issue but other way round. 1.3 uses a 5" pulley and e16se uses a 6"
