Hey peeps have a bit off a odd one here... the pulleys on my engine have been replaced with the feed ones :) bonus huhh lol.. but heres the thing... the airpump has been disconected and bypassed as most people do, but the essentric shaft pulley has adjusters fitted but dosnt spin in a perfect circle, more like a cam kinda movment? is there any reason for this? done a search n spoke to a few at rotorstock but noone seems to understand why its setup like it is.. also will it be causing damage because it runs perfect..
cheers
Do you have a pic of it?
You are right in saying it should spin in a circle and not out of center, So is the Crank pulley aftermarket too?? maybe its just not set up correctly if it can be ajusted? or maybe its been damaged? May be worth taking it off and have a play with it (see if there is any signs of it being knocked).
It wants sorting because the pulley will be effectivly tightening the belt and slackening it every rev, so you properly have the belt set to slack and it should\'nt damage anything but if the belt is set Tight in the wrong place it will Goose your Alt fairly quick.
if i remove it, was planing on doing this anyways, will the timing or anything be all messed up? or is it just a case of it powering the other pulleys using the belt? soz for the noob questions lol..
Does the belt move up and down when it\'s running? Could just be an optical illusion?
But it is more likely something is wrong.
How do the replacement pulleys work? Is the whole hub replaced? Or is the pulley replaced on the hub?
The timing, in theory, shouldnt be affected, because the pulley has a "key" slot in it, and the key holds the pulley to the right place on the shaft. At the back of the pulley you see a circular disc with lots of holes in it, this is what the ECU uses to "see" where the shaft is. I doubt this has been moved, and I also doubt it would start if the timing was out.
Adjusters on the pulley - that sounds weird... yes we need some pictures of that.
i`ll take some pics n a video if i can lol..
kk some pics and a video, dosnt look as bad as i thought but still not a perfect circular movement, think im paranoid :P is this normal?

I thought the bottom one on your video was your water pump pulley. Could be wrong (often are:2Rolleyes ) but i wouldnt like to see that sort of movement from something as important as that.
bottom pulleys the essentric shaft pully bud...
On the Vid the large Bottom one is the Crank (black one) the next up is water pump and the top is Alt.
I would say that that it has an Inner Underdriving pulley fitted and it doesn\'t look like its sat properly on the Cranks Mounting.
The thing on the front isn\'t an Ajuster, its a form of Locking washer (not sure how exactly it works but if you take the four bolts out you will find the holes are not elongated.
TBH it doesn\'t look as bad as i thought it would, it would be worth taking them off and cleaning the mating surfaces (just so they are sat flat) and if its still doing it maybe stick a stocker back on and see if its the Cranks mounting plate or the pulleys.
O yeh before you take it all apart mark the Positions, its not realy important but because the bolt holes are not symmetrical the bolts will only go in one way (bit of a pain if there are a few Pulleys and you can\'t see when there lines up properly.
Also there are two sensors on the PS side of the Crank pulley try not to Knock them, they control the timing and have to be treated with respect.
its gunna be a knightmare to remove these aint it? :S cheers for the input :P not a major prob then.. i`ll try n remove it all tomoz n go fae there..
:Hammer :rollin

Nar easy, there just a pain to put back if you dont pre mark where they came off.

Don\'t bother removing the main 19mm es bolt in the middle. If you did and then removed the whole pulley assembly, you run the risk of dislodging the torrington bearings and then it will be a MAJOR job to correct it. You will be ok in removing the 4 little bolts though, as said just mark it with a screwdriver
Good point ^ That would create a world of Pain if that happened.
craig just rip[ the engine out and rebuild it you know u want to lol
then at least u know what goes where

Well i am on holiday for a week? lol...
cheers for the advice guys, didnt fancy removing the 19mm :Sdoubt id get it off lol
the pulley wont come off without taking the 19mm bolt off tho will it?
so if i leave the rest of the pulleys on and remove the bottom one, as long as there mark shud be a easyish job..
That is a stock eccentric shaft pulley mate, the plate in the middle is to lock the 19mm bolt so it cannot come undone.
The pulley should run in a perfect circle,if it doesnt its damaged.This will cause loosening and tightening of belts which will make them squeak but most of all will damage main eccentric shaft bearings due to the crank being run out of balance.Thats the worst case if pulleys real bad, if its slightly bent then it will damage bearings over time but either will cause a vibration through the car when you drive it.Vibration will also depend on whether you have solid engine mounts,if you have it will be worse.Take the drive belts off and see if there is any play back and forth/ up and down in the crank.
Yes removing the 19mm bolt will remove the whole pulley.As long as your careful remove the 19mm bolt(if you can get it undone/very tight) and fit another complete pulley.Make sure you do the bolt back up to the same torque setting it was before you undone it.
Either way mate get it fixed first before you start driving it.
so im guessing its just the pulley thats not seated right or damaged then? nothing like the essentric shaft bent or summink.. :S
anyone got a spare one kicking around?

keep me up? the jet dryers didnt even wake me up man, i was a tad drunk :S
Quote from: K1HKS arseThat is a stock eccentric shaft pulley mate,
If you look at the pic from at an angle (the first vid pic is a good example) you can see it has an Underdriving waterpump/Alt E-shaft pulley with a stock power steering/Air con pulley one the end of it.
YIP ITS A FEED ONE :) Oopes caps on lol.. well i had everything off and reseated, still a very slight bit of movement but its alot better now :) woohoo!
