Rb25det Altenator & Apexi Timer

[H@ME]

hey guys i just got back my r33 GTS with rb25det conversion, all has been great with the car and it hasnt missed a beat, however i have encounted this squeeking and first instints was it was the fan belt, i had a look this morning, and it is coming from around the altenator, could this be a possible loose belt? the noise was only came on during start up now, it is constant, i think it is possibly the bearings in the altenator? i have done the old, soap on the inside of the fan belt to use a dry lubricant to try stop the squeak, however it is still contant, any ideas on wat to do or try?

2nd part, is that i want to intall my apexi full auto timer for turbo and N/A, however, just want to know the basics of installation, any problems i may come accross and things to watch out for?

Any help on these two issues would be muchly appeciated!

Cheers, hame

easy way 2 check is the slackness in the belt u shouldnt b able to push the belt down more than 1cm. if it is more than that tighten it up and make sure the bolt at the back is toght. mine was a little bit loose and the belt was working loose and squelling. if the noise is still there then the next easy thing 2 do 2 check if it is the alternator is take the belt off completely and start the car up if the noise isnt there thats ur prob. hope that helps

hey man, yeah it think it is a little bit loose! can push down 1cm or little more, what do you mean the bolt @ the back? how do you tighten the fan belt? i'll wait for a reply on this and if this does not work i'll take off the belt and try again.

REGARDING TIMER, do you have to use a turbo timer harness?

[raps86]

if u look at the top of the alternator there will be a long bolt going 2wards the motor that will adjust the belt. along that bolt where it goes into the alternator there will b a 12mm bolt or nut i cant rember wat it is but loosen that then turn the long bolt also a 12mm head to tighten the belt up then make sure that u tighten the first bolt other wise it will work itself loose. u should b able 2 push the belt down about 7 -8mm is a good spot. i will try post a photo of the bolt 4 u.

Not to sure bout the turbo timer mine was already fitted when i bought the vehicle.

excellent i think i know the bolts u talking about the one almost horizontal and the other one faced the other way? i'll see how i go. let u know in 5! a pic would help clarify this however.

[raps86]

hope these help

[H@ME]

yeaha they are the ones i was trying to describe, the pics take a while to load. So which one do i loosen first, then the other bolt i use to tighten the belt correct? ... so ticky to get in there..

[raps86]

yeah loosen the back 1 first then turn the long 1. its the worst part bout performance cars everything is all confined.

[H@ME]

you can say that again, i just went and tried, the thing is tight, i using a socket set and i broke one of the connectors, i'll try use a spanner, and it was 12mm

[raps86]

yeah it sucks breaking tools. i was fortunate that being an apprentice so i hate a long spanner that came up behind the hose so i was able 2 undo it easier

[H@ME]

yeaha i only have a small spanner, and it too confined in there near the radiator hose, plus i have hybrid fmic and the piping is right in the way! so it a paint:(

[H@ME]

okies, i have found a longer spanner, the first bolt (the one u can't see in the second pic of urs, well the head of the bolt) is impossible to turn it stiff as, however the long bolt is eaiser, i have losened the long belt, and the fan belt has become lose..this sounding right?

[H@ME]

hey, tightened it up more, still getting the problem this is really annoying, is it a big hassel to take off the fan belt to find out if it is the altenator

[H@ME]

okies, i am looking for a new altenator now, what is compatible for a rb25det series 2?? Is it an easy bolt on bolt off affair?? Think this may solve my problem!!

Has anyone installed an apexi full auto timer to a r33?

If your current alternator is broken get it rebuilt by an auto electrician.

For info on alternator removal and replacement.

The alternator for all R33 RB25DET either S1 or S2 are both the same.

[H@ME]

Excellent, well thats good to know wat about across models, it hard to find an altenator, but i have found a rb26 one? are these compatible?

[H@ME]

i can get one off a rb25de for 70?? this a good buy and will it be a direct fit?

[H@ME]

hey guys i bought the 33gts alternator, looks to be in good condition, small differences are:

the 2 x earths on the back and the major positive wire location, this shouldnt be a problem i dont think.

- turbo one is 80amp

- non turbo is 90amp will this matter?

i installing it as we speak let me know what ya's reakon.

YEAHA!!! no squeeling!! i so happy, she all good again! but is the previous post's questions could be answered then that would be appreciated!! AMP difference. I have tightened up my belts even better then they were before i had the car back, i going to pick up the miss's from tafe, so i'll see how she drives. Thanks for the imput the tutorial was great dOOdz apart from i did not take of my FMIC pipe lol was lazy made it a little more frustrating, i did most of the work from under the car as i found it alot more accesible? anyhow thanks for all the imput guys!

hey ive go the same problem at the moment on my 33. pretty much squeels on startup then goes away, but at night time pretty bad.

i did all the spray lubricant and tighten belts but still same, turns out that at night cos heater and lights on squeels heaps but at day with no lights on its fine. so to test starts squeeling at night so turn everything off except lights and is fine bit weird but yeah.

so looks like battery is shagged so gonna recharge it. it nothing changes with the squeeling looks like replacing alt!!

ne one else found this lol
