hey all. I have to pull off the balancer from my RB30 bottom end and it is just a short motor. I rung an engine reconditioning place and they told me how they do it and I am not really keen on doing it till someone else says it will be OK.

they said a rattle gun will not have enough torque so forget that.

they told me to remove the sump and wedge a bit of wood between the crank and block then get a HUGE breaker bar on the balancer nut and apply a lot of force.

Will this possibly damage the crank? last thing I want is a bent crank...

sorry for the newb question :)

otherwise has anyone else got any ideas on how to remove the balancer from a short motor not installed in a car?

Hi CEF11E,

This is how i have done it before, and it doesnt damage the crank thats why you need to use wood as its softer than the crank so wont damage it.

I used a 3 foot breaker bar when i undid mine and it stil ltook alot of effort, and even then i needed to use a gear puller to remove it from the crank shaft.

hope this helps you

cheers

depends on how good your rattle gun is and air supply...

You should be able to do it with a normal breaker bar with 32mm socket i think from memory, if flywheel is on, use a screwdriver between teeth and the dowel on the block for the gbox. If no flywheel, put two bolts into the flywheel holes and put screwdriver between those two to hold the crank from turning while someone else undoes the crank bolt.

Then a puller to get the balancer off the crank.

27mm from memory.

the 'piece of wood between the crank and block' trick works well.

you arent wedging it on the main part of the crank, you're wedging it between the big counter-weights, and they are pretty meaty. you will not do any damage to it at all.

if u needed to remove the balancer with the motor in the car could you put the car in gear with handbrake on or will this damage gearbox?

to remove the bolt, get a breaker bar and have it lean over to the left hand side of the motor (right hand side if you're looking into your engine bay) so that it is levering on the ground.

then just crank the car and it will undo the bolt.

Yes, I believe that you are supposed to leave it in gear to undo it; alot easier this way too!

May get away with it this way with an rb30 balancer - I doubt it though as it will just slip the clutch. You can also remove the starter motor and jam the flywheel or drill a small hole through the bottom of the bellhousing and jam it that way.

lol you'd go to all of that trouble on a short motor when you could simple jam a block of wood in the crank somewhere?

Its seriously not that tight.

You just need a big breaker bar. :blink:

With a 1m piece of steel tube as an extension.

      For DBA, check out their guide table here. https://dba.com.au/wp-content/uploads/2023/01/Direct_Replacement-Guide-2021.2.pdf   Additionally they have some other guides and info on how to make sure you choose the right pad.

      Sorry, just assumed that talk of coloured pads meant EBC red/green/yellow/shit stuff. I don't know the DBA pads, but it's a reasonable bet that they will be OK. DBA make good stuff generally. Those 4000 series rotors I linked to are very good. I may well replace the RDA rotors I have with those when required.

      The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
