Is a R32 GTR harmonic balancer the same as 3.0Lt VL commodore or Aussi. skyline

Yes it should be.

The 20, 25, 26 and 30 are all the same but there was one difference in all of them and that was the power steering belt. Some used a 4 rib belt and some a 3. You have to make sure the balancer matches your application but even if the 30 has a 3 rib for the p/steer, you can still use a 3 rib belt on the 4 rib p/steer pulley.

The p/steer is the section on the balancer closest to the front of the car.

BTW when would you need a harmonic balancer?
^ anyone?

i hope these questions arent related.

i cant be 100% but EVERY engine has a harmonic balancer..

cant think of any that dont.

ATI lightweight balancer are for engines that are built for more revs than std.

a harmonic balancer balances the odd vibrations in the crankshaft caused by the explosions in the cylinders. a cranckshaft doesnt rotate perfectly if it wasnt balanced using a balancer it would rotate itself to shreds. the cracnk in a manual car is has to be balanced by a balancer due to clutch engagements and disengagements on the outher side of the crancnk which also causes odd virbrations

also its not a balancer, its a damper. It has nothing to do with the internal balancing of the engine components within. It simply sits on the end and absorbs harmonic vibrations and converts that energy into heat as its absorbs through the rubber rings that are within the hub.

A balancer implies that it is essential to have on the motor as the whole engine would be out of balance internally without it, a damper can be off the motor and it would still retain a 'balanced' state, however the shocks and vibrations would sure as shit kill everything.

I think alot of old style motors have true balancers eg. many v8's from the day.

Also you would most definetely need an aftermarket damper such as the ATI one when your are pushing the factory engine past its reliable redline, making obscene amounts of power or your into the serious drag racing thing.

      I left the ceramic coating off this bit, hopefully it just comes off after a few drives.   The gap between the spokes is too tight for anything on a stick, its only marginally bigger than my finger. I have to use a brush to get in there and its a big reason why I thought I'd try the coating.   Absolutely will do. I have EBC Blue Stuff pads to put on the front which will make them a bit dirtier. I'm hoping a pressure wash will just get most off. The shine is different to most, its very thin but seems very well 'attached' so hopefully it lasts.

      Barrels don't need to be shiny clean. But they are certainly nicer when they are not polluted with years of brake dust, and worse the rotting corpses of the last 17 balance weight sticky pads scattered all around.

      Use text replace function to auto-link to referred threads?

      By GTSBoy · Posted

      Yeah, type a special character like ^ or | to initiate the equivalent of the "at"ing for thread links. Although, it might not get any easier to manage. Imagine 30 or 40 threads that kinda match what you want, and the one you want is lost after a long list of useless ones. The magic keyword version I proposed would be a manual effort to set up each case. More of a directed effort from the greybeards to facilitate exposure of useful content. I'm not against the auto complete stuff being considered - maybe por que no los dos? (And where I said "triggered automatically" in my OP, I meant "triggered accidentally". Of course I want it to be automatic!!)

      Ah yes, fair enough! I was purely thinking about cleaning the spokes and front of the wheel with the mitt. For the barrel the rag on a stick makes more sense. I've tried cleaning the barrels on mine and gave up in frustration. Between brakes being in the way or spokes being in the way and limited space to constantly move the car front and back it was just too annoying. The barrel being as shiny as the rest of the wheel sounds amazing though. At this point I'm not even sure if they have the same surface finish on mine. But I feel inspired now to find out.
