Tintop cambelt change - difficulty?
Evening all,
i need to do a cambelt change on my venerable punto JTD
ive been looking around at the engine locking kits, are they really necessary? is it just a case of lining up all of the marks on the belt with the
marks on the pulleys? ive done belt changes at college on some old engines that were out of the car and they were really easy, do i need a locking kit
for a more modern diesel?
cheers
Matt

Some of the modern engines do require use of a locking system as they do not have
Woodruff keys on the crank pulley allowing it to spin relative to the crank,
usually as soon as you slacken the big nut !
Zetecs and a few French engines that I know of, there may be others.
The 1.250 Zetec in the Fiesta has no marks at all on the crank or crank pulley and relies
entirely on a locking pin.
Someone on here may have Autodata and could give more info but if need be I can get the
info from my friends one tomorrow for you.

I previously bought a locking kit for my alfa 147 and sold the kit on again for only a quid less than I bought it, get a second hand one of the bay
and just sell it on again when you're done

to the belt.........

Some cars seem to be designed with the sole intention of making working on them a pita. Like the peugeot expert, to change the cambelt you have to
take off an engine mount!
A bird in the hand....

Someone on here recommended the following if you can get suitable access:- Use a Stanley knife to cut the old belt to about half its width then slide
it to the back of the pullies.
Slide the new belt onto the front pushing the old belt off the back, then cut it & pull it out.
Slide new belt all the way on.
QED.

 nooooo don't do it....no like that.
What about replacing the tensioners, rollers and the water pump all the same time. THAT is a good practice. Most of the manufacturers insist now to
renew the above items.
For what you going to save by doing it your self after you had to buy the correct tools to do the job, and the troubles you can get in too, just not
worth it.
Find you self a good local indy and let them do it. Then if it goes wrong you know who to blame.
