HI ALL anybody know of a way of changing yr timing belt without lining all the timing marks up , because as from yesterday i found out how to and what an easy job it is so the next time i do mine i shall be using this new way of changing it you may scoff and say e don,t know wat e,s on about but the mechanically minded of u may know of this method already. so any guesses will b welcome ,,, should make a good debate so lets hear from u RSVP cully z:D :D :D

is it the old cut half the belt off and slide on the new one trick?

hi mikey groves spot on mate right first time i only found out yesterday i thought wat a bloody good idea cheers cully z:) :D :D

I think there was a discussion about this being a bad idea...

I think the general consensus was that it was a bad idea from the point of view that if the old belt is a) on wrong or b) stretched and you try to put the new belt on at the same time you are a) going to repeat the error or b) going to have a lot of trouble fitting what is a smaller belt to the same wheels.

 

IMHO the trouble would come when you start dealing with the tensioner. That and the fact that cutting the belt in half in the first place means going round the cams etc in some very tight spaces , or turning over the engine, by hand, with effectively a weakened cambelt doing the work.

 

It has obviously worked for someone, but it seems to be one of these ideas which in the words of my DD granny "when its good, its very good, when its bad its F****ng bad"

paint old belt and pulleys etc .. as well as standard marks, if u think u r wrong slip old belt on again... if the marks are correct u will be fine :)

 

if not... it is better to know now

when i take my pulley of i am going to get it turned on a lathe

 

look at the back ... c that bloody great weight ...... some of it will be getting removed :)

 

will ask about balancing etc when i am there :)

Can you get lighter pulleys instead of that bloody great thing, cant help thinking its a waste of weight. And if so any idea of price?

 

Not trying to do a nelson though!!!

I think there are a few lightened pulleys available on the market, they seem to be made of alloy rather than the lump of steel that is standardTTZ---- PULLEYS

 

Try these, and they are red!!

 

HTH

Be cautious when messing with balanced engine parts, Nissan put a great deal of technical design detail in the z32 engine, if for a minute you could improve things by taking some metal off the back of the pulley I`m sure Nissan would have done it.

 

The pulley weight is taken by the crank and the mass it has works with the flywheel mass at the other end of the crank, start messing here and you may result in an engine not running as smooth as before, I know there are lightened pulleys and flywheels available but beware most of this type of equipment was designed for track cars where comfort and long life (regular rebuilds) is not a priority.

good point jeff

 

i had posted several posts about removing the lump of steel onb the back of the pulley

 

makes sence me thinks ... why make the engine slower to rev ???? must be a reason ?
