Chris Bailey Posted October 13, 2012 Share Posted October 13, 2012 I personally wouldnt they look kinda cheap and may not be reliable Quote Link to comment Share on other sites More sharing options...
jimmy1985 Posted October 13, 2012 Share Posted October 13, 2012 yeah stay away from ebay when it comes to things like this as it is a major part. I know it will be expensive (cause ive just got one) but try and stay with oem parts Quote Link to comment Share on other sites More sharing options...
safcdixon Posted October 13, 2012 Share Posted October 13, 2012 Three will probobly be fine but the crank pulley has no dampner so needs throwing in the bin, the others look fine Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 13, 2012 Share Posted October 13, 2012 I personally wouldnt they look kinda cheap and may not be reliable How do they look cheap ? other than not using the crank pulley for obvious reasons they look fine to me, if they are made to the correct dimensions on a CNC lathe and out of T6 60-61 then i don't see any issues Quote Link to comment Share on other sites More sharing options...
Suprakeith Posted October 13, 2012 Share Posted October 13, 2012 i agree they look ok to me i was thinking of getting set for mine,wouldnt use crank one but rest i would fit to car for sure Quote Link to comment Share on other sites More sharing options...

safcdixon Posted October 13, 2012 Share Posted October 13, 2012 There £5.50 i swear Whifbitz one are like £100 £5.50 isnt the buy it now price though chris, they are on bidding. Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 13, 2012 Share Posted October 13, 2012 I don't do ebay but guess you wont get a set for £5.50 ! The raw material costs would be way more than that ! Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted October 13, 2012 Share Posted October 13, 2012 £5.50 isnt the buy it now price though chris, they are on bidding. Yeah I know but still would you trust ebay special pulleys, I know if it was my car I wouldnt but that's just me. I thought I remember people saying stay away from Billet pulleys etc Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 13, 2012 Share Posted October 13, 2012 (edited) If their made correctly and out of the right grade aluminium alloy there is no reason not to use them, just not the crank pulley Edited October 13, 2012 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted October 13, 2012 Share Posted October 13, 2012 If their made correctly there is no reason not to use them, just not the crank pulley So if the crank pulley is bad, would you trust the rest of them? I suppose its like going single turbo you do it once and you do it properly. In this case you buy pulleys you know have been tried and tested Quote Link to comment Share on other sites More sharing options...
imi Posted October 13, 2012 Share Posted October 13, 2012 At that price its worth a punt. Quote Link to comment Share on other sites More sharing options...

In this case you buy pulleys you know have been tried and tested The OE crank pulley is also a harmonic damper, the billet pulley isn't a harmonic damper hence its not advisable to use it, the other pulleys are fine to use. I suggest you search crank pulleys on here Quote Link to comment Share on other sites More sharing options...
Noz Posted October 13, 2012 Share Posted October 13, 2012 If you get these, it's worth doing a hardness test comparable to the trader supplied products. Softer metals are an issue with stresses. I've seen some metal products almost fall apart because of cheap quality used materials. Oil & Gas industry for example wont use chinese metal as standard Quote Link to comment Share on other sites More sharing options...
Guest aspire Posted October 13, 2012 Share Posted October 13, 2012 At that price its worth a punt. exactly, im with dunk on this, CNC turned in decent billet material. cant go wrong Quote Link to comment Share on other sites More sharing options...
Guest aspire Posted October 13, 2012 Share Posted October 13, 2012 exactly, im with dunk on this, CNC turned in decent billet material. cant go wrong i work for aerospace company, TA TA steel has failed every test to date, why did we sell up our steel works!!!!!

Noz Posted October 13, 2012 Share Posted October 13, 2012 exactly, im with dunk on this, CNC turned in decent billet material. cant go wrong To be fair, I've seen cheap material turned on a CNC, the machining process it goes through has nothing what so ever to do with how good the quality of it will be. Worth a punt on the other pulleys if you want to save a tiny bit apart from the crank which you definitely shouldn't use, but decent ones aren't exactly big bucks.

suprasurrey Posted October 13, 2012 Share Posted October 13, 2012 I bought a three piece pulley set from Ebay similar to this set. It`s been on the car roughly four years now with no issues. I totally agree with Dnk, if they are CNC machined from the correct grade materials you should have no problems. Another reason not to use the crank pulley is that being made from Aluminium, it will wear quickly in the area that the crank seal runs on.

No offence but i don't agree with that and have seen some pretty crap machining done on CNC lathes and machining centers. A mate bought some CNC machined billet pulleys a while ago and they didn't run true or look very nice Obviously if the grade of alloy isn't up to the job then this will not alter no matter how good the parts look.

Think your getting wrong end of the stick. What I meant mate by my comment is CNC turned material doesn't mean it's good material, meaning if it was crap to start with it will still be crap afterwards. The quality of the material is not improved by any machining process if its poor (properties improvement not talking about burnishing etc), the quality of the features is a completely different topic. Material good or bad can be machined. It read to me like matey was saying if it's been CNC turned it must be good. I may have mis-read it.
