I have 1999 e320 with 33K miles and freshly out of warranty. I was working in the yard when I heard this loud noise from a car driving up the block. I t was my wife with the radio blasting and no clue what was going on. Towed the car to the dealer (first time at this dealer) yesterday and today I found out that it needs a new timing chain/cover and oil pan. But I guess I am lucky since the dealer told me that MB agreed to pay the entire bill.

Hi Sterling! (funny meeting you here!) -

Would you like to see one from my '80 928 S Euro? LOL!

DR.D

I wish there are more Tech like yourself. FAIR PRICE and on the lookout.

Qustion Dr. D

I am goign to change my Crankshaft Balancer on Monday.
I am changing this as a preventative meaasure.

How come you changed the BOLT. do I need to change mine as well.

Also, do I need to lookout for anything different. Also, changing the Motor mount L R.
I want to make sure this mechanic does it right on these 3 items.

Thanks

Like most MB engine bolts, the crank bolt uses a strech shank and
has a maximum service measurement. when you are dealing with torques of around 400+NM, I tend to replace these things.
Just like steering wheel bolts, why chance it to save $4?
Make sure your guy uses the correct balancer counter holding tool! If not, and he uses a flywheel lock or ring gear cheater,
you can bend or even break these crankshafts.
It takes the correct tool to hold these when loosening and torquing. PN# 112 589 00 40 00.
The torque is very important also.
step 1 ----- 200nm
step 2 ----- 95 degree angle of rotation.

Motor mounts are self explanitory.
Good luck.
DR.D

I HAVE A 1999 E320, SHOULD I REPLACE BALANCER NOW BEFORE IT FAILS OR JUST KEEP AN EYE ON IT. IT LOOKS OKAY NOW. DOES IT JUST FAIL OR WILL IT SHOW SIGNS BEFORE GOING BAD. THE CAR ONLY HAS 26K ON IT NOW. THANKS

1999...

I heard they fixed the problem in late 1998, see below.
I am sure DR. Diesel can put some input on it.

The rubber ring ( approx. 10-12mm wide ) near the circumference of the pulley is the problem. Prior to complete failure there is usually a noticable wobble of the pulley which can be seen with the engine running at idle.

"Group 3 - M112 & M113 crankshaft balancers that fail should be replaced with part number 112 035 08 00 or 112 035 09 00.

Improved balancers entered production as of engine end number 661775 for V6 and 166563 for V8."

Thanks Merc1. Hope Dr.D. is reading. My C280 was manufactured april 99. I'm already breathing easier.

So when you say "Improved balancers entered production as of engine end number 661775 for V6 and 166563 for V8."

You are refering to the last 6 numbers of the "11394460007935" number that is listed on my NETSTAT VMI printout for my 1999 AMG C43 manufactured on 5/7/1999?

That would mean that I have the bad part even though the car wasn't produced until May?
Thanks

Sweating with 55k miles....

Problem Fixed.

Changed the motor mounts, and runs great.

Also changed Crankshaft balancer as a precaution, noticed rubber was warped in the back. Whoow. Relief. Also, recommendation from Dr, Diesel, I also changed the bolt.

Another one in the shop today. 1999 Ml 320 with the belt slung off and balancer blown.

CUSTOMER COMPLAINT??? LOSS OF POWER STEERING!

Engine is out. We are replacing the front timing cover and upper oil pan.

I have a copy of the power steering clamp recall. What a joke. Mercedes states they are concered for our saftey.

IF this is the case? Why have they not done the balancers?????

If everyone who has had this failure reported it to https://www.peachparts.com/shopforum/www-odi.nhtsa.dot.gov/ivoq/Consumer.cfm then maybe there would be an offical recall like with the power steering clamp on the M Class.

Ok we have a 99 SLK230 and a 98 C280 should I go ahead and replace the org crank pullies with the updated parts?

112-035-08-00 Balancer updated $95.76
006-990-70-04 bolt $ 4.79
