Tricky-Ricky Posted January 9, 2012 Share Posted January 9, 2012 Common problem, get yourself a new/SH pulley, or aftermarket damped type, and obviously don't drive it. Quote Link to comment Share on other sites More sharing options...
fastcar Posted January 9, 2012 Share Posted January 9, 2012 I have heard of the bottom pulley coming off before but the oil pump pulley. I would do the tip ex test on the bottom pulley to as I should think that would not far from going ether Quote Link to comment Share on other sites More sharing options...
Guest Jaydutch Posted January 9, 2012 Share Posted January 9, 2012 i dont know what im talking about the oil pump pulley was a guess, its right in the middle of the engine block and its the lowest pulley Quote Link to comment Share on other sites More sharing options...

Guest Jaydutch Posted January 9, 2012 Share Posted January 9, 2012 cheers barney how the belt stayed on and i didnt even know it had happend is beyond me. good job the plastic was hanging down!! i live around the corner from toyota so was considering having it done there. any idea what a reasonable price to do this would be? i think id want a new belt seeing as this 1 could have been twisted like that for many miles Quote Link to comment Share on other sites More sharing options...
fastcar Posted January 9, 2012 Share Posted January 9, 2012 i dont know what im talking about the oil pump pulley was a guess, its right in the middle of the engine block and its the lowest pulley Have a look at titan Motorsport website they do a solid bottom crank pulley a lot stronger then stock could be an option to safeguard this from happening again if your planning on keeping the supra for a long time or upgrading the power Quote Link to comment Share on other sites More sharing options...
Guest Jaydutch Posted January 9, 2012 Share Posted January 9, 2012 the titan 1 is around £300, my brakes need sorting pretty quickly as well so im sad to say il be taking the cheap option thanks though Quote Link to comment Share on other sites More sharing options...

Guest Jaydutch Posted January 9, 2012 Share Posted January 9, 2012 might be a silly question but would this have affected performance? when i started it from cold the over evening it felt like it choked a bit at half throttle at 3 thousand revs... related?

Geo Posted January 9, 2012 Share Posted January 9, 2012 the titan 1 is around £300, my brakes need sorting pretty quickly as well so im sad to say il be taking the cheap option thanks though stock crank pulley is your best option here. They are roughly the same price £300 delivered. Got mine off whifbitz when Lee did my Build Quote Link to comment Share on other sites More sharing options...
Paul Whiffin Posted January 10, 2012 Share Posted January 10, 2012 Just so you all know, I sell my own full dampened crank pulley for the Supra now, see here http://whifbitzperformancetuning.co.uk/toyota-supra-supra-engine-components-camshafts-pulleys-belts-garage-whifbitz-p-5968.html you cant tell them apart from the genuine items, been fully tested for over a year now.

Scott Posted January 10, 2012 Share Posted January 10, 2012 Somethings not right here. Those belts look miles off (look at the twist that's been put in it to keep it on). IMO that pulley has went with the previous owner and they have thrown it back together quickly then gotten rid. You're VERY lucky that it's OK.

Guest Jaydutch Posted January 11, 2012 Share Posted January 11, 2012 had 1 of whifbits pulleys put on today toyota garage wanted £650 haha! and scott the belt was changed a few months back and it was fine. it twisted like that when the outer ring came off the pulley! thanks for help and advice guys Quote Link to comment Share on other sites More sharing options...
Scott Posted January 11, 2012 Share Posted January 11, 2012 had 1 of whifbits pulleys put on today toyota garage wanted £650 haha! and scott the belt was changed a few months back and it was fine. it twisted like that when the outer ring came off the pulley! thanks for help and advice guys That's very strange then as I can see no way that the belt can come off and twist the way that it has. If it had twisted the other way then that could be explained but it's actually turned in the way, something that I can't see happening on its own.

Guest Jaydutch Posted January 11, 2012 Share Posted January 11, 2012 i know lol its shocking how it twisted in that direction??? but the new belt was on there nicely a few months back its a mystery! Quote Link to comment Share on other sites More sharing options...
