Twin pulleys?
The engine i have has got a set of twin pulleys all around on it, complete with seized crank pulley! I am probably going to source a set of single
pulleys to replace these but wondered what engines had twin and what engines had single? Also are there any advantages/disadvantages with using either
(in a locost)?

Most of the Cortina, Sierra, Capri's and Transits had single pulley, suspect perhaps Granada had twin? Also some posted in the wanted section
for a twin pulley recently

In my experience of the engines (which is only about 4 of them) it's the later injection ones that have twin pulleys.

Sorry, should of been clearer. My engine is out of a 1986 Sierra 2.0iS. I was trying to find out what engines didn't have twin pulleys but it
sounds like thats most of them so i shouldn't have any trouble getting a set.

My 1989 2.0 with manual steering is twin pulley'd.
Fitting a new alternator removes one of them. The fan is gone so having two for that is unnecessary there too.
That just leaves the crank.
The twin crank pulley is a bit heavier but it has the benefit of the 4 threaded holes in the front- perfect for fitting a megasquirt crank trigger
wheel to! So I'm keeping it.
Ben,
My crank puller was pretty stiff too. But a hub puller soon sorted it.
HTH,
James

Success!
I removed my crank pulley today, using proper 'Locost' tools. I decided to make a puller at work, using work's materials, with
work's tools all while being paid to be at work, how Locost is that!
