Re: [MBZ] OM606 Timing Chain Wear Measure
Larry, 274k miles, only have maintenance record in booklet completed up to about 175k miles, almost all dino oil (Shell) but some Mobil 1 as well. Once I get this project running, and the memory of the expenses thus far fade a little, I'll probably install a new timing chain. If I can get access to a good dial indicator I may try to measure the chain wear using the official method. -Max -Original Message- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of LarryT Sent: Thursday, February 18, 2010 6:01 PM To: Mercedes Discussion List Subject: Re: [MBZ] OM606 Timing Chain Wear Measure Hi Max, How many miles are on the engine and what kind of oil has been used?

[MBZ] OM606 Timing Chain Wear Measure

Re: [MBZ] OM606 Timing Chain Wear Measure
Answering my own post here. Searched the archives and found an exchange between Ned Kleinhenz and Marshall Booth, here's the key part below. Ned if you're still on this list, I'd like permission to also post this great tidbit on the MBCA forum and credit to your name. -Max -- Glad I took Marshall's advice and replicated the chain stretch measurement on my '95 E300D with the OM 606.910 engine. My first measurement on Saturday was 4 deg. The subsequent measurements, today, were 3 deg, 2 deg and 2.5 deg. Think I'll keep this chain and check it again in 30 or 50k miles. I discovered an important trick that other 606 engine owners may want to know - The cam can be indexed for #1 piston TDC by running a pin through holes that align the left cam gear and the front cam tower. One of the bolts that holds the cam cover on the head is the perfect size to use as this pin. This bolt will fit tightly enough that I estimate the bolt will only fit through both holes within 1/2 deg of crank rotation. When looking at the engine from the front of the car, correct crank rotation is clockwise. To measure chain stretch, you must approach the index postion only from the clockwise direction. Backing the crank off a fraction of a degee reverses the play in the chain and makes the measurement meaningless.
