Clutch oil for a Hartman?

[Terry Armstrong]

Guys,

Sure do appreciate all the advice! It's good to know that their are options available since nobody has the Hartman oil. I have never had the opportunity to run a Hartman clutch, so I'll probably go the ATF route. Synthetic seems like a wise choice since most or all synthetics perform better at extreme temperatures, and I assume these clutches run quite hot.

That's what is so great about Vintage karting; lots of people willing to share knowledge on what works!

Thanks again.

These old motors, clutches and pipes don't run like today stuff so don't "overslip" the clutch and heat won't be a problem.

Now I'm really scratching my head. L&T "rocket lock" is a very thick clutch oil, for organic wet disc clutches. This goes against what was posted....what is the deal??
