Installing new Crank pulley/Harmonic B

[CruisinGA]

I'm swapping crank pulleys to a 2F double pulley one for P/S, I've removed the old crank and am trying to install the new one.

The old one took a LOT of cranking on the puller to get off.
I cannot get the new one or the old one back on.
I measured the ID of both, they measure to the same 1/64", but the needle is just a tiny bit to the left of the mark for the new pulley.
I rented a harmonic balancer installer, however my crank doesn't have the threaded inner hole needed to use an installer.
I've cleaned the shaft and the ID of the pulley with sandpaper, greased both, and checked the keyway and key for any mishapeness, etc.
I tried heating the I.D. of the pulley with MAPP gas to get it to expand to no avail.

I'm out of ideas and need some help. I really need to have my truck back on the road tomorrow. Thanks.

Try some dry ice (from Baskin Robbins) on the shaft.

In my experience, more effective than heating the pulley.

So you like using dry ice on your shaft, largenfirm?









We have better ways of dealing with that problem!

That's the only way to make it shrink, man...

Welllllll
got 2 pounds of dry ice,

broke off two apple sized pieces, proceeded to try and cool the shaft as much as possible.....
Got it frosty white cold. REALLY cold.

I can get the pulley on about 1/2" and no more.

PLEASE help.

cool off the shaft like you did and heat the pully real hot shoould slide on with no effort!

Heat the pully and freeze the shaft. Just be ready to put it on quick. the temp will even out fast.

Don't have to worry about toasting the front main seal?

I didn't have an extra hand today, I'm leaving in an hour for my soccer team's training camp. I will get an extra hand and try that when I get back. Hafta drive the 80 instead of the 40 cause I couldn't get that damn pulley on.

Yeah, just get the whole pulley nice and warm. Bake in the oven if you can(make sure its PERECTLY clean, or it'll smell up the house, and your next pie will taste funny.) I'm not sure how hot you can get it before you'll cook the seal though....I'd guess 200F would be ok sice the engine runs at 190.
