Sigma Cam belt change

[sprocket]

Hi all, I'm about to change the cam belt on a 1.6L Sigma in a 140 Supersport and have heard that the standard Ford camshaft locking tools are not suitable due to different timing.Can anyone who's done this job offer any words of wisdom?

Many thanks

Having watched my cam belt (2012  Supersport ) being changed last year it’s quite a complex job.  Stuart at Premier Power is the man to go to for this.

Thanks for the recommendation for PP but I've changed a couple on regular tin tops and fancy the challenge of doing my own if I can.

I tried my local Lotus / Caterham guy to change my Sigma 140 cam belt but he declined when he realised what was involved.  His experience was mostly with the K Series, which having helped do that it is a lot easier.  I also got Stuart at Premier Power to do it.

I saw this when I first looked at doing it myself- https://www.pistonheads.com/gassing/topic.asp?h=0&f=101&t=1602254.  It was too challenging for me.

Quick search of the archives. But if those hits don't include:

• tools
• how "Sigma" engines differ
• links to a manual

please let us know and I'll have another look.

Thanks all for your input. I now understand that this requires a full manual set up for the timing so will consider whether to do this myself during the winter or get someone else to do it.

Cheers
