Removing Harmonic Balancer Out Of Car - Will This Be Ok?

[CEF11E]

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.

Thanks!

will give t a try on the weekend!

cheers dudes

wait yeh...27mm sounds better haha. i know where i got 32mm from haha stupid speedflow fittings and not having proper 1 1/4" spanner.

I did the piece of wood, and break bar trick too.

Worked too easy.

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?

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

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.

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.

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