Luck was in.

Post by Ivanerrol » Thu 02 Nov, 2017 5:45 pm

Just come back from driving Melbourne - Noosa return - in the W210.
30 k's from Melbourne I had to gun the engine to get out of the way of an idjit.
Just after there came a knocking noise and squeeling noise from the engine when the AC was actiavted.

M112 harmonic Balancer failed. Lucky I made it home.

M112 harmonic balancer problem was a compulsory recall in the U.S. But of course not in OZ :bs:

Having said that. The harmonic balancer itself is not that expensive. But needs a special MB tool to remove.
Anybody got one they can lend or want to sell? :dontknow:

Otherwise I'll just have to buy the tool from the U.S.

Skip the tool you can do it with a impact wrench if you have one. Even a $50 one with 100PSI at the regulator should be able to pop it easily. Otherwise you will need the tool. This is also one of those jobs it's probably cheaper to take to a shop to do, just bring your own part as the cost of the tool will outweigh any of the labour as it's very easy to get to on this engine.

This also looks like an easy and cheap way around the tool:

Canadian Mercedes youtube mechanic Fupabox has a video on removing the harmonic balancer.
He bought the correct tool to do the job. Even with the special tool he needed a pile of force to remove the centre bolt.

I've spoken to a couple of MB specialists about changing the balancer. They'll do for less than buying the tool and importing it from the U.S.
Having said that I'll be removing the viscous fan clutch and fan shroud before taking the car to get the unit changed. I have bought a new unit already.

Yeah that think is on pretty tight, un-necessary in my opinion but im not an engineer. I think its like 200nm + 90 degrees. I'm not sure what this comes out to. But I just bought a impact wrench for $50 that will do 360nm. Anyway glad you got it worked out and no major damage. My M112 w209 doesn't look to be running perfectly but looking at all youtube videos they all seem to have a little wobble, so I'm leaving it till it's more ovious plus its 03 so it should be out of the problem range.

It's the AC compressor causing the issues :Doh:
Costs more to fix than the harmonic balancer. :banghead:

It's the bearings in the compressor and not the clutch bearing

Oh sorry to hear man, I was thinking it's a bit fishi that it just went bang as normally the harmonic balancer starts to make some weird noises for a while before it craps it's pants.

I would honestly just get a compressor from a wrecker and change it myself it's pretty easy. Here's the basic things you need to know if your interested:
1. Take it to AC place and get them to vacuum out all the old gas.
2. Drive the car home, don't turn the AC ON! Alhtough im pretty sure it wont work anyway it will probably self cut off with no refrigerant.
3. Remove the compressor
4. Drain the oil out of the old compressor and out of the wreckers compressor and put it in your newly sourced compressor (the oil from your old one that is).
5. Attach compressor
6. Go to you local AC place again and get them to recharge.

I'm thinking tops the whole thing will cost you $300-$500 depending on the deal you can get on the Used unit, being the W210 and M112 which is as common as hell I think you could easily find one for $150 on ebay or gumtree, just bargain with the wreckers they are very negotiable.

More luck.

(a) I found the correct compressor lurking in a cupboard in the garage.

(b) The W210 is sold :Doh:
Mate came in and bought it -wanted it for some asylum seekers
I'll change the compressor and seals but they'll pay for the regassing.

The trouble with getting the compressor out of the cupboard in the garage is wondering whether or not it's any good :banghead:
I usually mark bits with a NFG if they aren't right :whistle:

I've sourced 3 separate units from sleezeebay and wreckers - all have seized compressors :bs: The sellers swear black and blue that the compressors have been tested and are OK. more :bs:

Are you sure they are seized that seems like incredible bad luck with that many.

Seized. Out of the last 6 used compressors I've bought at wreckers 4 have been NFG.

The compressor I put in seized at the shop putting the Gas in. :banghead:

I have one more in the garage - if that one is no good I'll end up getting a new one from the U.S.
