95 E300D my new tensioner modification

My old tensioner assembly was a little worn & bouncing. After researching what might cause wear, I decided to try adding a zert and mixing MoS2 powder with a Krytox grease. I used a small grease tool left over from my tractor tools that allowed a small quantity of grease to be loaded and gently tapped into the tensioner pivot arm. I quit tapping when it felt like all the air inside had been replaced with grease. The shock, pulley wheel, and arm are new. Stabilizer shock, INA arm and pulley. Old pivot bolt measured minimal wear so I reused it. Also reused the thin seal ring from the back of the old arm.

Pictures show products used to make the grease. I mixed about 10% powder to the Krytox. They are both top rated lubricants.

Also a picture to show that the tensioner bolt appears to go in far enough to contact a rubber seal with a hole that exposes the timing chain. I put a little silicon grease on that seal in an attempt to make it last longer.

I know it may not prove out, but I'll feel better knowing I can add a high quality lubricant when I want to.
