Twincam16seca Posted December 10, 2012 Report Share Posted December 10, 2012 Hi all, Just wondering what brands of adjustable cam gears are "safe" enough to buy from ebay as i'm looking for some for my 4agze. So basically wondering if the cheap as ones like these ones http://www.ebay.com.au/itm/Adjustable-Toyota-Corolla-GTS-4AG-4AGE-85-91-Cam-Gear-Gears-Pulley-/271117640231?pt=AU_Car_Parts_Accessories&hash=item3f1fdee227&_uhb=1#ht_2935wt_1037 are just as good as the more expensive ones like these http://www.ebay.com.au/itm/TODA-RACING-Cam-Gear-Pulley-LEVIN-TRUENO-4AGE-16V-AE82-AE86-AE92-One-Pair-/321025211793?pt=AU_Car_Parts_Accessories&hash=item4abe97fd91&_uhb=1#ht_2314wt_919 let me know what you all have!

filfrederick Posted December 10, 2012 Report Share Posted December 10, 2012 I have used the megan racing gears that were quite cheap, the outer is aluminum so would not last as long as the steel ones, and i replaced all the screws as the heads were a soft abd easily rounded. overall not too bad.

rian Posted December 10, 2012 Report Share Posted December 10, 2012 4AGEs are non-interference engines, so a cam gear failing wouldn't be that bad. But if it were me, I'd probably buy some T3 cam gears, they are less than $200 I think. Quote Link to comment Share on other sites More sharing options...
towe001 Posted December 10, 2012 Report Share Posted December 10, 2012 Years ago when i had a 4age i was looking into the idea of making a pair of them. Wouldn't have been all that hard, have both cam gears sitting next to each other - one right way up and the other one upside down. Cut the cog part off one of the gears and the other one remove the centre part where the gear fits onto the cam. When you look at both cam gears sitting together and look at the adjustable ones you'll figure it out what needs to be done. Quote Link to comment Share on other sites More sharing options...
aspheric Posted December 10, 2012 Report Share Posted December 10, 2012 I recently bought what I believe to be the exact same product from a different seller (maxspeedingrods-au or something). Havent installed yet but I was sold by the fact that the outer ring is steel not aluminium. You seriously can't argue with the price either. Although that being said the T3 items look to be well made and worth the money. The bolts look like they aren't the greatest on these and I might replace them. Wouldn't be too keen on the dynamic timing changes if they loosened themselves :b Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted December 10, 2012 Report Share Posted December 10, 2012 don't buy anything that has aluminium/durilium outers, hard anodised or anything like that as it's just not worth it. Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted December 10, 2012 Report Share Posted December 10, 2012 I asked my buddy to make another set of the type I sell: http://www.ae86drivingclub.com.au/forums/showthread.php/72751-Adjustable-cam-pulleys otherwise I have seen the T3 ones first hand, a bit bulky but they seem pretty decent.

parrot Posted December 11, 2012 Report Share Posted December 11, 2012 don't buy anything that has aluminium/durilium outers, hard anodised or anything like that as it's just not worth it. Why do you say that Sam? I would have imagined lower reciprocating mass etc (which I know nothing about) woud be a good thing. I wouldn't have thought load on them would be that high, and as long as protected by a cover, they should be OK? Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted December 11, 2012 Report Share Posted December 11, 2012 no their not: I have another one just like from a different source it in my garage right now. Yes that's a genuine HKS Quote Link to comment Share on other sites More sharing options...

Trev Posted December 11, 2012 Report Share Posted December 11, 2012 (edited) That is from a poorly tensioned (over tight) belt. Edited December 11, 2012 by Trev Quote Link to comment Share on other sites More sharing options...
Sam_Q Posted December 11, 2012 Report Share Posted December 11, 2012 I understand why you would think that however I beleive that normal wear would eventually do this regardless of belt tension. Misuse or not this shouldn't happen. I have reports of being common and I have seen it on other types of pulleys as well, aluminium is just too soft.

Hiro Protagonist Posted December 11, 2012 Report Share Posted December 11, 2012 That's an old style HKS gear, the newer ones (which don't have the fugly blue) supposedly have fixed the problem Quote Link to comment Share on other sites More sharing options...
