A how to question

Greetings
So I am stumped.
I have acquired a BBM project in a box. I’m ready to install the Jesel belt drive. It’s my first encounter with one of these things.
So how do you hold the cam to torque the 3 bolts holding the sprocket drive to the camshaft? I’m ready to clamp it in some soft jaws, but maybe there’s a smarter way.
Thanks
Rip

The Jesel kit should have come with a "spanner wrench" kind of tool to hold 2 of the 3 holes at a time to allow you the torq one bolt at a time...Other than that just torq them once it's all together and just put a socket or dowel of some sort in one of the crankshaft balance holes and turn the crank until the socket rests against the pan rail

Clamp the cam in a vice between two pieces of wood as close to the end journal as possible. Torque to spec and you're golden.....Just make sure to use blue loctite.....and the torque spec isn't much, something like 25ftlbs or so....

It is just a steel rod, about a foot long, with two Allen bolts with the same O.D. as the I.D. of the hub. The bolts are exactly the same distance apart as any of two of the three holes in the hub.

You just hold the hub with the took and torque the third bolt, roatre to the next two hole and repeat, and so forth.

Here is the whole installation kit:

Thanks! I had no idea that there was such a tool. I'll confess that I clamped it between two pieces of wood, which worked fine.

Can easily make one with two allen head bolts and a piece of steel. What I did years ago and works just fine. Allen bolts slide in the holes on the cam gear steel rod to hold it.

That's why I posted both options!

Some folks are more handy with building their own tools than others!

Nop reason to be so touchy, just reiterating what you said. Which is EXACTLY what the Jesle tool is.
