Balancer query

[Drew Pojedinec]

I've never used a performance harmonic balancer, so not 100% sure on what is normal

From crank snout to outer edge of balancer I've got .190  (so crank sits just inside of balancer).
Only .035 between water pump pulley and balancer.... seems a bit tight.

Do I need a smaller water pump pulley or is the balancer not all the way on?
(I do indeed have a tool to install balancer btw, it felt like it bottomed out)

Many thanks,
Drew

Some balancer/dampers require a hone, or polish of the crankshaft snout to get the clearance necessary for the damper to fit against the crankshaft timing gear.  Also, some dampers require you to boil it in water to increase the clearance from expansion, and quickly install it on the crankshaft before it cools, and torque to 75-100#.  Joe-JDC

Hadn't torqued it on there yet.  The spacer is against the crank slinger, the balancer is hard against the spacer so I don't think a hone or heating would help a lot.
I'll torque it on tight in the morning and see where it ends up.
Worst case I can't use the waterpump pulley, or I need to work it a bit on the lathe.

Thanks for the input Joe, appreciate all of your work.

Guess the install tool didn't pop it all the way on.
It went in a hair more when I torqued the bolt down.

.080 clearance now, which I feel better about.
