jza800 Posted May 14, 2020 Share Posted May 14, 2020 (edited) I am having a little issue after mounting a new timing belt. i have mountet a racing blue timing belt on my 2jzgte, but can see the tap i have on the timing belt cover (have attach a picture with a red ring), it is touching the timing belt on the outside of the belt, around 0.5 cm from the front of the engine and in, but on the timing belt, i did see it as i have a blue timing belt mountet, and i did see some blue material on the cover that goes over the cam gears and coils.. is that a comment problem when mounting another timing belt than stock? what does that tap do??

mellonman Posted May 14, 2020 Share Posted May 14, 2020 Can you not just move it out a little so it doesn't rub Quote Link to comment Share on other sites More sharing options...
jza800 Posted May 14, 2020 Author Share Posted May 14, 2020 Can you not just move it out a little so it doesn't rub That was my thought to do, but i am just wondering why it is only touching the about half an cm on the belt and not all of it, i have attach a picture of the belt i have, the red line is about the width it is touching on the belt. maybe the belt is thicker than normal. i have look on many engine picture, and i have a hard time to see if people remove that tap..

Mike2JZ Posted May 14, 2020 Share Posted May 14, 2020 You don't need to remove the tap, and it's not normal for a belt to be touching, regardless if its a stock or aftermarket belt. Normally the only time the belt touches the tap is when the belt is not installed tightly or correctly. Please upload several photos with your belt installed showing the problem please, hard to understand from your description Quote Link to comment Share on other sites More sharing options...

Normally the only time the belt touches the tap is when the belt is not installed tightly or correctly. Please upload several photos with your belt installed showing the problem please, hard to understand from your description It should be mounted correct, all marks are spot on, and the tension should be within spec, as you can't do anything with that, as the Hydraulic tension should give the correct tension to the belt. on the longest side you can twist it quater of a turn so the tension should be ok. it got a new gates rpm timing belt, with new tensioner and Hydraulic Tensioner.. it is hard to take picture of, but if you stand in front of the engine and look down on the cam gears, i can see on the belt that that tap have touched the belt, as the blue colour was on the tap and was removed from the timing belt, but it is not the whole width of the belt that have touched, only aout 0.5 cm from the outside of the belt to the inside, just like the picture further up i have attach.. i have run with a gates racing belt before with no problem, so could the rpm belt be thicker than stock belt and racing belt?

jza800 Posted May 15, 2020 Author Share Posted May 15, 2020 But can i move out the tap, with no issue afterwards? it looks like everything is as it should be with the tension.. what does that tap do?? Quote Link to comment Share on other sites More sharing options...
jza800 Posted May 16, 2020 Author Share Posted May 16, 2020 Better picture of the problem. the tap have been moved a little out to clear belt Quote Link to comment Share on other sites More sharing options...
jza800 Posted May 16, 2020 Author Share Posted May 16, 2020 I think i have found my problem, the bolt that goes thru the tension are too tight, i had the old tensioner laying and the bolt pops thru with no problem.. so the tensioner can not tension the belt enough thru it is very hard..

Scooter Posted May 17, 2020 Share Posted May 17, 2020 Are you compressing the tensioner and putting the pin in to secure it before bolting it in? Quote Link to comment Share on other sites More sharing options...
jza800 Posted May 17, 2020 Author Share Posted May 17, 2020 (edited) It is this tension i am talking about. The bolt that goes thru the bracket have a tight fit, and dont goes easy thru the hole. They are all New, so the other hydraulik tensioner was pulled together with a split you pull when fittet. So am i right that the tensioner i got is faulty??

Mike2JZ Posted May 17, 2020 Share Posted May 17, 2020 There is a washer that goes between the bracket and the oil pump. You put the bolt through the bracket, then put the washer on and install onto oil pump. If you don't have the washer the tensioner bracket will not be able to rotate and you will have problems. Have you got the washer installed? Quote Link to comment Share on other sites More sharing options...

Have you got the washer installed? I have that washer on Yes just not shown on the picture. .. But I had the old tensioner lying it did not thru out, so i tried to slide the bolt thru that, and that goes thru the hole with No force at all, and I kan slide it back and forth with No force, if i do that with the New bracket, it slide in but only with force, and it does not freely goes back and forth, there is resisten on the bracket, that way i am sure something is not right. So the clearence the thr bolt goes thru have to be the wrong size? Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted May 17, 2020 Share Posted May 17, 2020 Check your bolt and the new idler bracket dosen't have any burrs or machining imperfections that could cause the problem. If nothing obvious then send it back to supplier and get them to send another brand. I can recomend using KOYO idler pulley set. I don't know what brand you have been supplied with but looks different to the KOYO. Failing that just go OEM, more expensive but guaranteed to work.

Bolt looks fine, no score or anything, the new idler pulley is a ntn brand seems ok too but have never heard of it.. the used on i have is koyo, and it fits perfekt in the bore the bolt goes thru.. will send it back or see if i can get some money back from it, so i can buy the right one..

But I'd certainly bolt it up and see if the problem goes away, at least then you'll know that the new pulley is definitely the problem Quote Link to comment Share on other sites More sharing options...
