Febi tensioner vs Mercedes

I have been reading all the posts about changing the timing chains but
I have a couple of quality questions. The mercedes brands on the tensioner is about $345 and on the gears about $180 each. The Febi brand is about $80 for the tensioner and $25 for the gears. The chain I get using Mercedes but is there that much difference difference in the other parts. All of a sudden if I use Mercedes parts one is looking at $1000 for parts alone. So convince me that the difference is worth using an oem tensioner. Thanks

Hi Stutz,

In addition to the above wisdom…

In my opinion, this one part is SO critical to have right, its just NOT worth it to futz around in an attempt to save possibly a couple hundred dollars….

It would be a massive and avoidable shame to have an aftermarket chain tensioner bleed down .. chain jump time … etc…. Possible subsequent damage & costs might well be staggering by comparison.

Good luck man,

Yeah, avoid the Febi tensioner. Febi isn't universally junk (I have a "Febi" oil pump in my SEC that's just a re-boxed OE pump, for instance), but it's a brand that has at least as many misses as hits, quality-wise. Caveat emptor. Not sure what the failure rate is, but I've heard enough bad reports that I'd leave the original tensioner in before I'd use the Febi one.

You should be able to do the whole job for $500-600 in parts. I priced it out a couple months back, but can't remember the exact number. Most people don't replace the sprockets, and it's not necessary unless you've got really high mileage and/or they show a lot of wear. It's the tensioner and plastic guide rails that cause failures.

The chain (iwisketten, means iwis chains) are the same whether from the dealer, or at lower price from various online sellers.
However, the dealer has a nifty looking bronze master link I am partial to for only a few bucks extra.

Thanks guys. I will heed your advice. One quick question on the work. The searches all talk about doing the timing chain work but do not mention whether to do valve seals when you have it almost that far apart. I also have not seen where the seals are an issue, but is this something I might want to tackle while doing this? The car has 100,000 on it. I do appreciate all the comments. I also have a R129 and without that combined Mercedes knowledge I would be lost.

I don't know about the seals either but with the chain guides in particular the consensus is that they should be changed every 100K miles but especially with our cars now at 25+ years even the low mileage examples should have them changed. The tensioner, as was stated before, should go ahead and get a MB part instead of taking the expensive roll of the dice with aftermarket. The window and boot rubber are another to go MB with. That list that PWogaman posted, I have it saved here and refer to it when shopping for parts

Some days it's just not worth chewing through the restraints
