Zetec Crank Locking Bolt?
Anyone know where it is?
Supposedly to lock the crankshaft during cambelt change, or is it an urban myth?

Ideally yes but you could just line up the marks then stick it in gear and put the handbrake on.
One other thing when changing cam belts is disconnect the starter or the battery --- else a moments forget fullness and you could end up with a
shed load of bent valves.

hi
theres no crank lock that i have seen before although some kits do come with pins
all you need to do is line up the marks pop the rocker cover off and put your 6mm plate across the rear of the cam shafts to lock them then replace
the belt
remember to renew the tentioner as there is a modified ford part for those

It's a 10mm bolt on the left side of the block just below the breather box. However it doesn't lock the crank but acts to stop the rotation
at TDC when trying to rotate it forwards. It can still turn backwards.

There's a tool to lock the cams, not the crank but most use a piece of flat bar to do the job.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

A bit of 5mm key steel does the job,I have seen the locking pin position which is blanked off with a bolt, to use it you require a bolt of exactly the
correct length or the correct locking pin.I just put it at TDC using the timing marks and fit the cam locking bar.

Be very careful i used the proper tool and pistons was not at TDC, i was very lucky as my engine is low compresion as it is turbo charged.

the benafit of changing the tensioner is that it doesnt fall appart and kill your engine the adjustment is a bit different on the modified part saving
the belt from going slack a problem ford noticed on the zetec even if it has the modified part they are changed as part of the ford schedule for that
engine
