Cylinder numbering

[Matteh]

did a quick search, but couldn't find anything...

I've gone to connect my ht leads on the 172 engine but need to know what cylinder numbers are which

the mk1 16v is cambelt 4 and gearbox 1, but I hear the 172 is cambelt 1 and gearbox 4?

which is the right numbering?

 

[mattjk]

I'm sure the gearbox on my 182 is 1 and cambelt is 4

 

[bmh.01]

Yep, No.1 is gearbox end and No.4 is cam end.

 

[alexbleubolt]

i think you guys have it around the wrong way, it says on the coil, the numbers (down where the bolts are that hold it on).

 

[alexbleubolt]

ie no 1 is cambelt and no4 is gear box

 

[ditz]

this confused the arse out of me today aswell, french tend to call the 'front' of the engine as we know it number 4, meaning starting at the front (belt end) is number 4

 

[alexbleubolt]

well mine runs around the other way, and runs fine, go figure

 

[Matteh]

I've connected it up with number 1 lead (and number 1 coil) at the gearbox end

well mine runs around the other way, and runs fine, go figure

Forget any numbers on the coils you have, cylinder 1 is flywheel end.

Why you lot go to go and throw confusion into the situation!! You had the answer in 2 posts!! lol

 

[alexbleubolt]

i rekon your wrong, unless you have different coil pack

 

[ditz]

worst way is it wont start and you'l get a bang
if that happens swap em round,, but start on the assumtion that gearbox side is number one and you wont have to change them

 

[alexbleubolt]

yeah, go for it. (changed my ht leads the other day and it runs fine myway)

Let me make it a little clearer then!!

Cabin​

Cambelt end 4 3 2 1 Gearbox end​

Me bending over​

I can confirm that 100%

As long as your reffering to the 172 an not the 197 itl be the same!

 

[alexbleubolt]

yep i changed my cup leads, and mine go the other way

Cabin
(coilpack)
3 4
2 1​

Cambelt end 1 2 3 4 Gearbox end​

[mattjk]

LOL okay then! now im really confused! Thats deffo my setup we need another opinion really

 

[alexbleubolt]

guess it depends on how your coil pack is

 

[mattjk]

I'v got 2 and there both the same, If your 100% sure thats just weird

 

[alexbleubolt]

yeah, humm, maybe its that beer i had, i'll shine a torch on it in the mornign and tug some leads and see whats what.

 

[Matteh]

any confirmation? :S

 

[Fred@BTM]

i'm 99% sure 1 is flywheel, 4 is cambelt

don't get confused with firing order

 

[alexbleubolt]

depends how you number the coil end as well. ie which one on the coil pack do you say is number 1, and which one is 4 ?
mine is like this

Cabin
(coilpack)
3 4
2 1​

Cambelt end 1 2 3 4 Gearbox end​

But you could have it like this, and it would be connected in the same firing order

someones got it sussed!! ^^^^^

for the record, flyhweel end IS no.1.

Dont see how you can confuse this with 1342 tho lol

 

[Matteh]

right

my coilpack is:

3 4
2 1

and i've connected it up like this:

cambelt 4 3 2 1 gearbox



take it some coil packs are numbered differently?

 

[stan*]

the coils fire in banks (2 of them), so 3 and 2 can be reversed, same with 4 and 1, as these cyls rise and fall together.

I did think that afterward to be fair. but I kept my mouth shut as I wasnt 100%

 

[alexbleubolt]

^^ me too

 

[alexbleubolt]

i still think my ways better, who wants to count backwards, it 1234, thats what i was taught at skool

i no mine is a 1.6 - but thats my setup too..

 

[Barron]

bumping this....

so which is the correct way?

Cabin

2 1

Cambelt end 4 3 2 1 Gearbox end​

Me bending over engine




i currently have it like that and my ph1 isnt firing =/
​

 

[mattjk]

Cabin

Lead numbers 4 3 2 1

Firiring order 1 3 4 2

You standing over engine


So basically you want the longest lead number 1 over on the gearbox end]

prettys sure thats right but im quite pissed now lol!

 

[Matteh]

mine was running fine Barron's way
