Are rb30 balancers the same as rb25 balancers, as i have spun the harmonic balancer on the rb25 in my 32.

need answer if you are absolutely sure

thanks

anybody????

im pretty shore the rb30 one is different cos the belts are differnt on the rb30 u need the rb25 one so that all your belt line up and fit correctly

Lots of people use rb25 balancers on their rb30det's. Not always that simple though.

im pretty sure they are very similiar except the rb30 has a v belt for the aircon i think from memory whilst the alt and power steering are the same....or i could have a few mixed up there.

[nick81xd]

well i dont have aircon. just the usual power steering and alternator. does this mean it will be right to use?

[munro'sgts-t]

should be by the sounds of it by wat r33-racer is saying its just he air con that is different being a v-belt

thanks for the help so far .

might just get one tommorow and give it a shot, only $15 for a 2nd hand one anyway haha

not if you want to run a v belt for the aircon. the 30 ones are smaller aswell and less suited to revs. bigger the better or by by oil pump. i can see you went to repco or something and pulled out the ol mckay balancer book lol.

[nick81xd]

aircon is not a issue in this case. i wouldnt of thought the oil pump as any thing to do with the balancer as the two are not connected mechanically.

the car parts stores in bundaberg are useless, they just looked at me blankly when i asked for a set of lifters for a RB25, so not even going to bother about the balancer.

just wanna know if it will be right to use temporarly so i can see if its the noise i have and until i can track down a proper one.

what u gota do nick is,make sure u gap ur synthetic oil,then make sure all ur muffler bearings r polished then maybe the tick wil go away so i can flog tractors lil heart out hahahaha...mmmm

[nick81xd]

for the record RB30 balancers and keyways will work on rb25 cranks. as mentioned the aircon pulley is different though .

thanks.

are you sure this is correct, coz i went out and bought a 25% underdriven power bond balancer which is obviously much smaller and is ment to be a lot better than the stock ones due to its smaller size. and all the power bond balancers on display for drag etc were much smaller than normal hence it must be better??
