cam belt fitting tip
this is an urban legend aboutchanging cam belts. ive heard it from a couple of mates in the trade but not from anyone who,s done it. the idea is that
you get a stanley blade and with the covers off and the engine running  touch the blade against the belt until its gone right through effectiveley
splitting the belt in two. cut the outer belt off leaving half the belt in place with everything still tensioned and timed right , fit new belt with
the old half width belt still in place then cut old belt push new one into place job done.i thought that you wouldnt be able to feed the new belt on
but it does work .i did a 16valve megane which is a definite need the proper locking kit engine yesterday .the only thing i did differently was cut
the old belt with the engine cranking not running.

I'm not sure I'd like to do it, but it does sound like a cool idea!

I wouldn't want to watch such a feat, without being behind a protective screen...
Can't see the two belts being exactly the same length, hence the tension would not be correct on the new belt...
Better doing it properly imho.

Yes heard it but I would NEVER try it, I might have a slight snigger when you post about belt braking, due to incorrect tension, pulley's &
or tensioners not replaced appropriately.
DO the job correctly and do it ONLY once.
If you can't afford the correct tools to do the job correctly then don't do it.
Oh and a lot of belt systems have guided pulleys (plates each side of the pulleys so the belt can't come off) so what are you going to do
then.

Fitted loads of cam belts in my time,now why didn't I think of that,sounds like a good idea,the only risk if the belt breaks while your cutting
through it,with it being 1/2 the width,but would be unlikely,give it a go,you try it 1st and tell us if it works LOL 
Edit To add then you could just retention the new belt after

sounds ok for an anchor (pinto)
BUT NOT VERY GOOD IDEA on new stuff!
thats why engine have tensioners, and alot of engine now day have pullys that you spin to take that dreaded 1/2 tooth out of !

this was a test as i have locking kits for most cars and tensioned the belt with the locking kit in place afterwards i just wanted to see if its bull
or not.with all the pulleys still being tensioned with the old belt in place the new belt just pops on with finger pressure.
the point i was making was its an urban legend (sort of) and ive proved to myself that its true

heard a similar thing on the MX5 where you push the old belt towards the engine so its only half on, then put the new belt on.
Tried it by a road side with IrvineD, ended up having to read the manual line by line as it went dark to make sure we got it right.
oh those where the days......
