I'm stuck!!!

If anyone would care to show me how to tighten/re-fit my cambelt I would be eternally grateful and some beer money would be thrown your way.
Would get a garage to do it but the car's in my back garden and not drivable!!!

Long shot but you never know.
Who wants to be my knight in shining armour?

As title says I'm in Pontefract.
Cheers peeps.
