Just working on the car last night and spied a very smal nick in the belt.

Quite rightly, I'm taking no chances, so I'm gonna do a cambelt change.

What do I do - this is the only thing I've never done on a cossie before, so a little unsure of how to go about it!

Any suggestions please?

Remove Bumper
Remove Radiator
with car in neutral, line up the TCD marks (see picture below)




Remove Auxillay belts
Remove bottom pully
Check all timing marks
Slacken tensioner
Remove Belt


Refitting is the same as removal -0 but swearing in different places

new belt needed and if if hasnt been done to your knowledge before, a new tensioner pulley.

you need a couple of spanners and make sure you time it up right before starting. details of th etiming marks etc are in the tech essay archive

Check if the mark on the pulley for the cam sensor (phase sensor in ford speak, lol) is lined up correctly to begin with, if its not then dont rely on that mark to re-align it afterwards, go by the rotor arm instead.

Its a piece of piss, there really isnt anything difficult about it at all other than that.

Dave Henshall

yep, just when u get it right it will jump a tooth before you get the tensioner right, there should eb just enough tension so that the longest length of the belt (ie from the right pully going down) you can twist the belt though 90degrees.

i managed to do mine with all the bits in place, just removing teh cambelt cover, ( 3 torx bolts and a 8mm bolt at teh bottom) and the fanbelt, thats on an escos though...

as above, but no need to remove bumper and rad though

Graceland

the only difficult thing is removing the bottom pully as the bolt can be an arse to slacken, and the pully can brake if seized on


full details of what to do here - 2wd and 4wd engines are the same principle

You also need a box of tissues to mop up your tears when you hear the sound of metal on metal as you start it up.

RichardPON

Bumper's already off, and taking the rad out is a 2 second job on my saff

This should be an interesting job - esxpect a flurry of posts after 6 p.m.

Gracey, yeah my pulley was a bitch.

didnt have the right puller so it took 3 of us and some lever bars and a couple of hammers to extract mine.

Do NOT whack it hard thoguh, you need to apply force all the way round at once, if you just twat it with a hammer it will break.

Graceland

if you have a 3 legged puller then stick that on, and then tighten the puller up so it is tight then gentally tap the pully with a hammer and then re-tighten the puller - keep doing this untill the puller works the pully off naturally


my pully was a right twat to get off - well, i tell a lie, the bolt was


Copious amounts of copper slip on re-fitting the pully

RichardPON

Yes, thank you for that.

I hope you contract some form of semi-serious illness

Hardest part is the bottom pulley, they can stick like you would not believe and they can drive you nuts. If you get stuck, walk away and come back a bit later! I've lost it many times and launched spanners, knuckle bars etc. Some people like to use a cam locking kit as well, but you don't really need one. Don't over tighten it when you tension it up and move it through 360 degrees manually before you fire it up to check you don't have any slip in the belt and you've moved off TDC!

Dave Henshall

i managed without takin ghte bottom pulley off, if its nice and tight, leave it alone,

there is juist enough room to slip the new belt in anyway with a bit of giggling...

Anonymous

Dave, i always do vauxhall ones that way, but it me it didnt look like there was enough clearance on the YB to do it and guarentee it didnt get damaged in the process TBH

Dave Henshall

it is tight and you do have to bend it quite a bit, but nothing severe like crimping it over or anything like that...get it on the bottom pulley first while you can still move it at different angles then the rest is fairly easy. i allways run it round with ni plugs in by hand a coupkle of revs to check that the timing is still correct and for any damage to the belt itself.

RichardPON

Okay, I KNOW the bottom pulley bolt is easy enough to undo, but I'm worried about taking the crank pulley off, as I've seen em before where they're complete bastards.

I've never done a cambelt on this engine in 6 years, although it's done less than 10k in that time , so I think I'll do a belt AND tensioner to be on the safe side.

Can I get the belt on and off without taking this bottom pulley off then? I've seen it done that way before, but, I presume, by removing the CPS bracket?

Glass Eye

pond, good advice,,get someone else to do it for you as i know you are crap with spanners,, stick to the hair dressing its more your style

One of teh most important things to remember, and no ones touched on this yet, is that the tensioner MUST be done up CLOCKWISE.

was just about to say that stu beat me to it

and rich .. i managed to do mine .. and changed the camshaft seals .. and i am technically challenged

Pon, crank pulley can be anything from real easy to real bastard, our 2wd one came off like a dream, my 4x4 one required lots of wd40 and every kind of lubricant I could think of, then a three legged puller got it off relatively easily.

I'd give it a try before giving up tbh.

Also, found an impact wrench is the best way to get the bolt off/on

Make sure you don't line up the 16 deg BTDC mark by mistake as it is easily done



Mark

Ginge !

if ya di tap it with a hammer avoid the 4 timing marks as they snap of very very easy !!!!!

but pon its not that hard, the tensioner needs doing that wa or it will come a tiny bit looser on tightening

oh and makesure the oilpump/dizzy pully is lined up as in the photo, look in the archives theres a class post about it, showed me alot

oh and ONLY USE THE BOTTOM PULLY TO TURN THE CRANK OVER, not the cam pulleys as that make em jump a tooth when turning if the belt turns out to be a little loose

when i done mine i managed to take my cam belt off by sliding it over the pulleys, never undone the tensioner AT ALL

guess what the timing was out a tiny bit too, cant think how that happened

good luck, if ya need anymore advice ya got rob and steves number , as no point taking mine unless ya fancy buying a new engine after ya put the phone down

RichardPON

Okay - the bottom pulley is a complete fucker and has just shattered

This is why I fuckin hate cars

Three legged puller I've got has a point on the bolt, so I don't know how you'd use that effectively?

Ginge !

pon ya can borrow mine if ya like and get me another one when one comes up cheep if ya like as my motor aint going together just yet

Who told you that bollox?...
It needs doing clockwise as its oblique and CENTRES the belt within its runners.

cossy abuser

can be done without removing bottom pulley, cut old belt off and wind new belt around bottom crank gear
10 mins to do once you have done a few,

Not recommended way of doing it so Q the start of the non professional procedure messages

I have a crank pulley if you need one
call 0800 B.E.D.R.O.O.M.T.R.A.D.E.R

RichardPON

LOL @ Simon

Well now I have absolutely no choice but to take the bottom pulley off.

Another addition to the Cosworth wall of shame!

cossy abuser

get some freeze spay and spray on the pulley, it may shrink it enough to aid removal

Dragon

Please do it the 'PROPER' way!

Jesus fook, winding belts up over the pulleys?!!

Excellent bit of advise from RS2300 4x4

Guinnless

Regarding the bottom get a proper harmonic balance remover. They're not too dear and it's a lot less stressful.

No need to remove the rad using this equipment either just undo it and swing forward. Obviously if you have a 500 spec coooler you probably have to remove it first.

Neil S

iTrader: (1)

Guinless I was going to say the same about the proper puller - a 3 legged one will likely snap the timing tabs!

Clean the holes out with a tap first tho PON

Neil.

cossy abuser

Says he that doesn't even drive a Cossy

RichardPON

Neil,

Pulley's shattered now anyway

Rad and cooler are all out anyway as it's a 2 second job on my car.

Excuse the ignorance, but what does a harmonic balance remover look like?

You truly are a complete moron.

The "lol @ Simon" was in reference to cossy abuser's 0800 bedroom trader comment, because cossy aubuser's name is................. yep you guessed it...........

You really are a paranoid delusional wanker aren't you?

Why on earth would I be making a comment about your alter ego on a post about my cambelt? Fuckin twat
