JB Weld Cam Chain Tensioner?
04/17/24 at 07:36:00
Having zero welding experience, a desire to DIY, and a tensioner which needs elongating, I am tempted to attempt affixing to the end a drilled piece of metal using JB weld epoxy. Is this a bad idea? The tube claims to be able to withstand over 4700 psi of force, but naturally, this bond is something I absolutely do not want to fail. Does this seem like a good idea? What other options do I have?
I have also seen photos of 3D printed extensions which attach at the original hole on the tensioner. Does anyone have a 3D model for this?
Thanks for looking!

If it fails to hold, your wallet and your engine will both experience catastrophic damage. It is much cheaper and safer to find someone that can weld yours or just purchase a modified tensioner from Versy here on the forum. The Versy tensioner is pinned so it can't come apart inside your engine, which is another reason to go with the Versy tensioner.

Bad idea. Trying to use a wad of JB Weld like some kind of super glue will fail between the stress and vibration. When it fails, you'll have a torpedo and scrap metal fying around in your engine case.
Get the Versy cam chain tensioner.

Do it right or do it twice...and be prepared to spend a lot of money the second time.

Sure 4700 psi on a.150*.630 surface or .26 square inches equals 1119 pounds of strength versus the strength of steel 30,000 psi
No welded steel is going to be much better
