I’m stuck please Cher my photo and see if you can help
I bought the puller from repco. Removed 24mm bolt
And bought n M6 70mm bolts to attach the duck foot.
I’m stuck as no matter what I do the balancer wont come loose
Any ideas ? I need to remove it to. replace the seal it’s pouring out oil.
I don't know how politically correct this is but it has worked for me in the past.
Tighten the bolt in the centre as much as you can then tap the end of it with a hammer, the shock can release it.
Like I said, it has worked for me several times without any problems but it might not be the right thing to do.
You are going to have to use some common sense here.
Put the main bolt back in place but not all the way in, and use the head of the main bolt to pull against.
MAKE SURE once the puller has come out a little that you then move the main bolt out further BUT NOT TOO FAR THAT IT HAS VERY FEW THREADS TO HOLD IT.
Put plenty of oil on the threads of the centre bolt. You don't need friction getting in the way when pulling the balancer off.
A rattle gun or long breaker bar may also help.
You really need this. I have heard of people getting them off with the tool you have but it can take a long time.
Rambunctious is on the money. Put the centre bolt in (not done up or anything, wind it in so there's like a centimeter of threads showing) and then use the puller. The puller uses the centre bolt to push against.
Hmm I see some issues in pics..no harmonic bolt in so threads are prob damaged in the crank..hope the 3 puller bolts are short or the CAS has prob been damaged...anyway... as above balancer bolt in till 5 to 10 mm of thread showing...ring spanner on balancer bolt head(to stop puller screwing bolt in as tension go's on) then puller over the top of that,puller bolts done up so you have a few good threads inside the balancer...tighten puller up till tight and walk away for a few min then 1/4 of a turn on puller wait few min another 1/4 of a turn and so forth eventually the puller center bolt will be easier to turn then just undo until balancer hits the bolt head reset and do it again...the balancer is friction fit so it will be tightish 90% of the way.....
once you opened the 24mm bolt on the outside of the harmonic balancer just leave it on a couple of screws, then use the balancer tool to pull it once pulled as far as the 24mm bolt uncrew it all the way off and Harmonic Balancer should slide off with ease just did a ecotecs balancer into a super 6 balancer and thats how i got it off.
Thanks to your advice I have used the Center bolt and bought longer M6 bolts 100mm to be able to push on the main bolt and release the harmonic ballencer. I removed the old seal and replaced it with a fresh (new) one. I made a seal assistance tool to gently tap in the new seal. Worked a treat was very pleased with the job it did. If anyone I was interested I have posted a photo of this.
So at this stage Im ready to reinstall that’s ballancer. I have lined up the key way and hand fit the balancer on the shaft.. I have inserted the 24mm bolt back in the center.
My new question is how do I push the new balancer back in ? The bolt doesn’t seem like it will do it easily. So close to the finish and yet another step I am going to need to educate myself on with your assistance I get this done.
Am I missing a tool ? Can anyone please help ?
I already have one thanks for the advice.
Worked a treat thanks
Thanks for your help. The puller worked out excellent
236 dollars for a puller lol
yeah it is crazy but that is what they charge and you can't pick up the Commodore puller anywhere for 60 bucks like you can with the normal finger type one. Can't they be bought for about $165? I've seen them that price.
If a manufacturer read that they would want to jack the price up ...
I have this type of harmonic balancer tool and covers most makes and models to both remove and install.
In your case, put a little oil on the crank snout and inside the the balancer and use the bolt to pull the sucker on. Once the balancer is fully seated, remove the bolt and clean any oil off the front of the balancer/crank snout, then put a little sealant on the washer and re-install and torque to spec.
edit> And don't forget to put a little oil on the balancer shaft OD where the seal sits, if it's installed with a dry seal it will likely burn out and fail in short order.
I was wondering if those kits would work on a Commodore. I heard they should work. I have a Dayco one in my eBay watch list that i plan on buying at some stage.
Some do, some don't. Need to double check. Mine also fits the older Holden 308/304 engines which was what I bought it for primarily. The best part of these kits are the mandrels that screw into the snout of the crank which makes everything much easier. Mine also has a Torrington bearing which removes a lot of the friction when cranking on that bolt.
found one on ebay $165
