My new project, 190e 2.6

Bit of an update since last time.

I finally got the idler pulley tensioner thing in the post from eurocarparts, as it had to be ordered specially. Put it all back together with a new belt and the engine is a lot quieter now. Its still a bit whiney, but nowehere near as much as it was before.

The next issue that had arisen was a nasty droning/vibration through the whole car at specific speed. Around 55-70. It was really quite intrusive.

As it was purely road speed related, was there on acceleration, slightly worse on overrun and braking, but dissapeared if the clutch was pressed, It was fairly obviously a drivetrain issue.

After doing a bit of searching and posting on a 190 forum I was told there is a few main causes for this.

Flex joints on the propshaft failing
Propshaft centre bearing failing
Gearbox or Engine mounts perishing
Or differential about to blow up :(

So the other day I jacked the car up to have a gander.

Front Flex Disc. Looks in good condition. Somebody has changed this fairly recently I think

Centre Bearing. This had me worried at first. While it turned smoothly there was a lot of movement in the rubber here.

Rear Flex disc, similar condition to the front.

Now this had me worried at this point. The discs looked good, so this pointed to either gearbox, diff, or mounts. :mad::mad:

Then after doing a bit more prodding I found one of the bolts on the front flex disc was very loose! So loose I could spin it about with one finger! I took a video of it here for anyone interested:

To get to the bolt I had to remove the rear gearbox mount thing, and then I could get a spanner behind to hold the nut while I tightened the bolt.

So, then I put it all back together again, in the hope this loose bolt may have partly caused things. I got down the road into an NSL, and accelerated. No Noise, No vibration. Just a smooth ride.

:D I coudn't beleive it, one bolt, was causing an incredible vibration.

So thats one more issue sorted.

There is a touch of vibration, and squeeling on the brake pedal now, and looking at the discs they are fairly worn all round. So my to do list looks like this now

Discs and pads all round. OEM discs, Greenstuff pads.
Oil Change
Springs. The rear springs are very tired, and it means the back is sitting too low, causing excessive wear on the inner tread of the tyres. New springs all round I think. Possibly some -40mm ones.

1 bolt - Nice one!

So glad the engine on my C180 seems to be in pretty good nick, but its only the 1.8 so not quite the same smoothness as that big Straight 6'll have.

When does it get its' first polish then? :p
 
Its already had a bit of a clean, but I'm not really a very good cleaning car person. The best i can do is throw some water and shampoo at it. I tried to t cut one of the panels but got bored as they are too far gone really.

Hoping to get hold of some decent panels for it to tidy it up, but I think it needs new wheels first really as they are obviously correded and let the whole car down a bit really.

i know naff all about mercs, and naff all about RWD cars.. but the flex disc spins, yeah - so instead of taking the gearbox mount off to get to the bolt.. why not just rotate the prop?
 
Because the flex disc is set back in behind and above the rear gearbox mount. The only way to get a spanner to the back of it to hold the nut, is to support the gearbox, and remove the mount. This just about lets you access the bolts at the 4 and 8 o clock positions if you follow.

most cars don't have wide angle mirrors on the passenger side, so it's not like you're losing that, but my leon has two full size mirrors and they're out of the vw parts bin so it's very strange.
it's probably for city driving, so you can drive closer to parked cars without hitting mirrors..

My mums Golf Mk 4 has two identical mirrors.

got ya. i hadn't realised the picture was of the rear flexy disc, and was thinking it had plenty of room to get the bolts at the bottom!
 
I didn't really have much knowledge at all before I owned my last two cars. I have always been quite mechanically minded, and able to take things apart, and fix things.

My first of those cars was a 106. The diff exploded on it, and I couldn't really afford to let a garage fix it. So decided to give it a stab myself. Eventually got it fixed, and then sold it on.

But with this car, I just read the buyers guide on the 190 forum, and asked for advice as I've gone along. The only real way to learn is to get stuck in really. Just buy something cheap and try and maintain it yourself.
