Help ASAP: which timing belt roller to use? 32 or 46mm?
My 951 is an '87. When, I pulled the timing covers, the roller was a 32mm roller and the one I got in my kit from LR is a 46mm roller. Should I use the new 46mm one or just use the old 32mm one? I need an answer ASAP.
thanks in advance

if your engine has the autotensioner and belt guide on the waterpump, you should use the 46mm one. the smaller one is for the old eccentric style tensioner on the early cars like my 86 turbo. the PO of my car had the 46mm one on my car nd the belt was like a 1/4in from touching (cog side) NOT GOOD!!!
