1200 virnier pully.

[novarodnherr]

:? I got a squre touth pully also bottom end and water pump
:?: can i fit them all on my 12 to make it all squre touth ?
Iknow the timeing belt is longer with squre teeth,
:?: what timeing belt do i need to get it to fit, my 1200 block{ ie number of teeth}

[Snowface]

are you saying your water pump and crankshaft sprocket is square? and your top pulley is what? round?

just get a square tooth top pulley to match bottom stuff.

[novarodnherr]

Ihave been trying to get a round touth vinier pulley for my car for 2 mounths now.
all i can get is squre touth.
I was going to change all pullys to squre touth witch can be done, i think !
It is just that the timeing belt is longer with squre teath.
do you know if the water pump would turn round far enough to take up the slack or will i neen a smaller belt.

[novarodnherr]

just to let you,s all know
1200 round touth timing belt 101 teath.
square touth belt 104 teath
when all is fitted ie water pump, bottom end, cam pully. onto the 1200 the square touth belt is to big
So you cant change a 1200 to square touth.
someone please lend or sell me a round touth verinier pulley

[Aragorn]

all the later engines ie GTE etc use round teeth so whats the problem?

square teeth was only used on 1300s and very early 1200 carbs everything since then was round

[novarodnherr]

The problem was that I can't get a second hand round touth virnier pulley.Icould only get a square touth.
Now I know it won't fit for the belt to big and theres no smaller one.
Ionly needed the round touth virnier pulley to set the engine up for were not aloud to race with one on the car.
You mite think Iam a cheep skate but Iam 15 and still at school and DADS on a tight budget.

take your existing pulley and elongate the pin hole for the locator, that way you can have the right teeth and have adjustability, and im sure the other racers do that too ;)

[Snowface]

This'll conduse you.

The 1.2 round tooth top pulley i have is different to the 1.6 Round tooth top pulley i've got.

The grooves are deeper in the 1.6 i think.

[novarodnherr]

Snowface you are confusing me even more. Itook round touths of 16s,14s and 12s. 90% of them are the same.

Stuart I think thats a good idea but Elongateing the hole,. will the pulley not move ! Is the pin not to keep the pulley in place ?


Cheers lads

[Aragorn]

pins just there to locate it

bolt holds it inplace

ive seen the pin shear clean off before when the bolt isnt tightened

[novarodnherr]

thanks aragorn
I was not sure u could do that. if it has been don before.
Has any 1 don this
Has any 1 seen this work ?

[nathan.]

I take it you've got an aftermarket cam. thats why you need a vernier. If you elongate the locating pin hole on the pulley like stuart say's, the pulley should slip on after setting lift on the camshaft. then tighten the pulley and it won't slip or move anywhere.

[novarodnherr]

Thanks Nathan, it looks like thats the road Iam going to go down .

I will try this and let you know what the rolling road results are.
I hope to get my dad to pay for the test


:wink: Thanks lads
