Harmonic balancer holder tool M112/113

Post by Manya3084 » Mon 08 Oct, 2018 10:07 pm

Hi all,

Does anyone know in melbourne where i could borrow or even rent the harmonic balancer holder tool...or even a tip on a way to remove it without the tool.

My clk320 balancer is cactus, and the rubber has started to deteriorate. I have one on order that I should be getting sometime this week.

Thanks in advance.
Anthony

Well, didn't get any response here so I ended up sourcing & purchasing the tool through Alibaba for $90 delivered.
It arrived today and it took not even 20 minutes to remove the old one and install the new one (new bolt as well).
With the new one installed, my belt tensioner finally stopped bouncing up and down like crazy.

So if anyone in Melbourne needs assistance with a harmonic balancer replacement, I have an awesome paperweight that could come in handy from time to time :laughing6:

Sorry no one came back to you. I read your post but had nothing intelligent to offer.

Can you post some pictures please?

The rubber on the M112/113 harmonic balancers is a known problem.
Originally a recall in the U.S. - but not here.
It's common.
Allegedly caused by oil leaks (oil leaks from the oil cooler gasket or the inspection plate gasket)

If you have oil leaks at the front of the engine in the oil cooler area, get them fixed pronto.
A failed harmonic balancer can come off and cause so much damage to the front engine area, the cost to fix maybe more than the car is worth.

The cost of the oil cooler gasket and others required is ridiculously expensive. Stealership - $160+.
However the ebay PRC ones are junk

Amazingly, I didn't have any major oil leak. I did have a very slight leak from the oil cooler and I used the china seals. So far they have been good (6 Months). Think I paid $7 for the kit, although I had to buy the silly 46mm socket to remove the oil filter housing.

Anyway, here's some picks of the tool and a demonstration of how it hold the balancer. You'll need a really good breaker bar and even a steel pole to crack the old nut. I used an old fence pole i had lying around.

You'll see the rubber from the old balancer started to detach revealing the shiny metal within. It's also quite cracked at the back.
