friend is having trouble getting his harmonic balancer off a rb30 in a 1989 r31 skyline

its a 1 peice harmonic balancer

whats the best way

:D hi doug

just had the same prob with mine. If you have tried a rattle gun and it doesnt work get a big breaker bar and socket, park the car on the concrete, disconnect the coil lead and crank the engine a little bit at a time (better if there is 2 people so one can keep any eye on the bar while the other one cranks it). Mine came loose after about 7 cranks

If you already have the bolt out but cant get the balancer off go and buy a balancer puller they start from about $18 for a supercheap one but most dont come with the correct bolts for the balancer so just go to a nut and bolt place with a bolt that does fit and ask for some high tensile ones

i took mine apart about 3 hours ago (stupid VL with stupid cooling system setup, blew a stupid headgasket.....stupid) bolt came free real easy for me, little to easy..... but anyway. try the starter method, but before that, try what i did, i just got a socket and breaker bar, had it facing straight up, and put my foot against it, then braced myself against the car, hard to explain but just try it, you can put heaps of pressure on it with your foot, or just kick the f*cking thing till it cracks free

yeah as above for the bolt, however the harmonic balancer it self is another thing

pack the hole with grease, get a tight fitting piece of steel(or another bolt that will take up the area of the hole)

grab a hammer and slam the bolt, the grease will act like hydraulic fluid and push the balancer off,

or ya could stop being a cheap a*sand just get a harmonic balancer puller from super cheap for 20 bucks

To remove the bolt use the above mentioned cranking the engine approach, easily the cleanest and most effective way. To pull the balancer, only use a puller.. bashing the thing is only going to damage the crank.. and potentially the balancer while you are at it.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.

      It's most likely the bolt/bush where the cover bolts back wore and allowed cover to move forward.

      Still haven't put the injectors and R35 AFM in so we can tune the bloody thing for the HG highflow it got mid last year! I think I can forecast the upgrade path to a bigger twin scroll, external gate, Haltech, flex setup, Samsonas, dis dat, etc will be .... a while away!

      Should have taken that opportunity to slot in a twin scroll turbo setup. Maybe next time.
