Does anyone know the length or link count in a te 610 silent timing chain? I want to try a different brand of chain. These factory chains stretch out way to fast. A good chain should last a lot longer than 6-10.000 miles.
They are 122 links in length. Husqvarna supposedly used three different DID chains in the 610 engines: DID SCA0412A SDH DID SCA0412SV-122 DID SCR0412SV-122 Supposedly, the "SV" marking indicates a special coatings on the pins, which reduces wear. I ordered a DID SCR0412SV-122. I have found documentation from D.I.D. that shows that the chains that have an "SCR" prefix have a slightly higher average tensile strength than those that have the "SCA" prefix. So that is why I ordered the one I did. My engine is at about 8000 miles, and the adjuster was at 7 clicks. I had the engine apart for another reason, so I thought it was a good idea to replace it now. I don't know if any other brands besides Husqvarna (DID) would give any longer life.
Your the man. Thank you a ton for the wealth of information. IOU a Bucket of beer if your in my area.
I'm curious--is there a way to tell when you remove the old chain which one it is? Is it stamped on the chain links?
My old chain has "04 SDH" stamped on the sideplates. My new chain has "SV" and "SCR" stamped on it. The "SCR" chain is the same inside width as my old chain: 7.15mm, but it is slightly narrower when measured at the pins: 10.30mm vs. 11.00mm. You can also see a difference in appearance. The interesting thing is that the old chain "looks" like it is stronger or more heavy-duty. But according to DID the "SCR" chains are slightly stronger. Time and mileage will tell me whether I made the right choice. I hope so....
