hello

im having a problem with my r32 gtr

ive got the crank pulley bolt undone, but now i cant actually get the pulley to come off.

ive been trying to use a 3 jaw gear puller to remove it, but its not working.

can anyone help me with a solution for how to get this thing off.

thanks

go to supercheap or wherever they sell car parts and get a harmonic balancer puller. on my car i ive got 2 holes to fit 10mm bolts, im not sure if its the same with the 32gtr.

if its the same, get 2 high tensile 10mm bolts and put some washers on them so they dont fall through. tighten the 10mm bolts onto your balancer through the balancer puller, then start to tighten the balancer puller bolt.

it should come off pretty easily.

Mine had chattered itself on.....took a hydraulic jobbie to get it off.....had to remove radiator, intercooler, oil cooler and front bar to get it off. Im pretty sure the factory holes are an M6 thread (read way too f*cken small)

the lower timing belt gear wasnt that bad. i used a long screw driver and levered it off evenly (making sure it lined up with the half moon thingos).

the only reason i did that was because my oil pump was screwed, i didnt really care about damaging it. i didnt put much pressure on it but there is still a chance of damaging it doing it that way.

thanks for your help!

at the moment i have some parts removed so i can get access to the pulley, eg air cond, radiator, so it wouldnt be that much effort to take the cooler and front bar off now.

there are two bolt holes on the front of the pulley, but someone else has tried to get this pulley off i guess, and now those holes have bolts in them, but the heads of the bolts are broken off, so i cant take them out anyway.

i am begining to think that maybe a hydraulic puller is needed, because it seems this pulley has welded itself to the crank!

also ive been told there is come spray called kroli that may be able to help loosen it, then heat the pulley up, then use the puller to remove it. im not so sure about heating it up, because i dont wanna damage the timing belt.

please keep posting any ideas you have on this matter, it is very helpful for me!!!!

thankyou!

thats the exact reason why you need high tensile bolts.

im sure you can use that tool that gets stripped bolt heads off (i cant remember the name, ive gone completely blank). its the tool where you drill right in the middle of the thread then tap this little piece that looks like a drill bit, then unscrew as normal.

saves you from pulling your front bar off i'd think.

I have had high tensile M6 bolts snapped off before...try and drill those suckers out...don't think so....a two jaw hydraulic puller is your only option

We had the same problem in my brother rb20 r31 he used to have.

Solution was to call a mobile mechanic. He came around, bent the shit out of his puller and charged $50 for his time. For the time and effort involved it was the best way to do it. Saved a lot more frustration.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
