So on the r33 that I bought not to long ago a new fault has apeared. There is a ring that is fitted behing the harmonic balancer and this seems to work its way loose and rub on the timing belt cover. is this a common issue. is there something that wasnt put back on when it was taken off. What will I have to do to stop this from happening as when it starts making its noise it sounds like the engine is running with no oil in it.

Have you got pics of what you are referring too? Sounds bad...

So what seems to happen is after a few days of driving the ring seems to slide back on the shaft and start rubbing on the timing cover. To rectify this in the short term I just lever it back into the crankshaft pulley with a large screwdriver. Think that pic pretty much shows it.

Harmonic balancer is probably done. That ring with the timing marks is part of thr balancer.

Unoess you mean the little silver washer that sits between the balancer and timing gear. But this cant rub on the timing case anyway

nah it is the timing ring. the balancer is tight, just that ring seems to be seperating. looks like its just another part that has to be replaced... now I know why they say never buy a mechanics car.... they can dodgy alot of shit that seems to go a month after owning it.

you mean the front backing plate that sits between the balancer & the cam sprocket?

You can buy them here:

Don't use those homo looking harmonic balancers, great way to smash a motor. Use a genuine one or a Ross Metal Jacket

ok so I have had a setback and progress.... I managed to find someone local to get a balancer off. Got it back home and the mechanic said there are hairilne cracks in the rubber so not to use it....$50 down the drain... come with a powersteering pump though cause he threw that in so I might be able to sell that to get some money back. Went and bought a removal tool as I didnt want to use a bearing puller like most people do and destroy the rings and set to stripping down to get to it. Back to the store to get some longer bolts. M6 x 1.0 x 70mm are the best to use.

Done some ringing around after pulling mine off and identifying that the bonding of the rubber between the timing ring and the main assembly has faid. $180 from a local nissan wrecker for a second hand part... not sure on whether this would be wise to get another 20 yr old part. New balancers priced from $480-580. Then I found a company in sydney that specialises in reconditioning balancers. They strip them down and rebuild them. Incl freight from bris to wagga wagga and back again it should only set me back approx $300, which is better on both sides as at least I know it will be a like new part but for alot less. Now just have to wait a week or so to get it back. well time to take a few things off around the engine bay, paint and refit.

Yep they are a pretty pricey bit of gear :)

Mine failed so i replaced it with a Ross Metal Jacket which cost me a fortune, only to find out someone had a brand new Nissan one for sale online here at SAU for half the price :/ Ah well!

Ross got the thing made overnight which was pretty damn impressive!

post-70965-0-94607800-1371212509_thumb.jpgI'm a bit confused as to how this goes together, does the plate get pressed onto the sprocket by the harmonic balancer or is it supposed to sit on this little half moon?

Edited by AngryRBGTX

ok. The keyway is just a small piece of metal like a half moon. It is removeable but not able to have its position changed. The harmonic balancer has a key hole in it so it can only go on the crankshaft the one way. I have another one here that I was unable to use that I will take a picture of and post on here shortly. Plus I will take a pic of that same washer that sits on the crankshaft coverint the timing belt pulley.

yep, you're 100% correct.. also don't get the plate on backwards, will destroy your belt

r34 uses different drive belts.

It could fit, don't quote me on that.

Have you had a look at Ross Nexus balancers? They're about 450$ New, cheaper than an OEM one. Or just bite the bullet and go metal jacket for 650$.

Pretty sure mine was different to a 33 as Ross had to change mine around...

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
