I looked into making a variation of the Zat tensioner, not too hard to do,
But I was cautioned against selling any. The liability issues are huge.
Do you have any hydrolic ones greg? They work great dry.
I have and have used pretty much every variation of tensioners. I don't like the mechanical one-period. It will work in a motor sports application by either pinning its rotation in place or as RJ says, simply rotate it to use up all the spring travel. But..
It roller is plastic and can wear & break down and the entire thing is a flimsy casting that looks like pot metal. Use it as stock with a hotter cam or upgraded valve springs and you have a guaranteed failure.
The hydraulic one is good when used dry. I feel it is not enough tension for a race motor that way though.
I modified a hydraulic one to use a bolt down the center so I could rigidly tension it. It works well, but is big and bulky. This is now installed on the Milano I race in LeMons. Belt skip is now a thing of the past. I run at 7300 RPM red lines all day long for double 8 hour race days. That's 3 to 4 races a year for two years going with this setup. The motor has even been spun backwards when the car was spun.
The ZAT tensioner I have is now on the GTV6 and I really like it. Its simple, robust and easily adjusted.
Belt technology has advanced light years since these motors were designed. The original tensioners were made to accommodate the weak points of the belts of that day.
I get the whole liability thing. That's where our country is going wrong... Personal responsibility, its a good thing.
Maybe I will post a drawing of the Zat tensioner and "open source it".
Hard work usually pays off.
After months of searching we got it.
