Crankshaft Dampner Separated -- Arghh!

I can do that. BTW, here's a plug for Barry's book (which came today) just in case he's too shy to do it himself.

The new dampner has yet to arrive, but I went ahead and started on pulling off the old one. I picked up the KD Tool Harmonic Balancer Removal & Installation tool. It's like all the rest of them, you have three little claw type things, a big bolt that goes through the middle of it, and a little pole that fits in the bolt and which pushes out in to the crank thus pulling the balancer off.



Of course, the little triangle claw things didn't fit worth a darn on my existing broken dampner and/or pulley and had a tendency to try and fall off (the dampner was on there pretty tight). The steel claw part comes apart and it was easy to fab up the pulley in front of the steel brace that the big bolt goes through, along with new two inch long 3/8-16 bolts (Grade 5) and hardened washers and then screw those new bolts directly in to the existing dampner. The little copper wire is just there to hold the steel brace lightly on to the pulley so it will self-center.







Once done, it comes out slowly, but easily.





And last, but not least, a shot of my "two piece" dampner. When my new Romac arrives I'll post shots of the install. I think the KD Tool will actually work for that.

Harmonic balancer torque specs for a 428FE are 70 to 90 ft.lbs. Forget the spring arm torque wrench. Get a digital or a click type torque wrench. Worth thier weight in gold. I use a torque wrench all the time from lug nuts to torquing spark plugs in aluminum heads!

Ahh, the new ROMAC aluminum/steel balancer is a dang nice piece. No timing marks, so I added three white lines at TDC, 10BTDC, 20 BTDC, and a RED line at 35BTDC.

Yep. Same one I have. A very nice piece!!
Good luck with it.

The ROMAC is on. A little anti-seize on the snout and the ARP bolt takes her right in. Torqued to 100 ft/lbs with blue loctite. With the slightly larger 7.5" dampner the water pump pulley had to come off as well. Tomorrow I'll put the pulleys back on her, adjust the timing pointer, and that should be it. Note the new-fangled ARP bolt that Barry was talking about. It has the 1/2" drive built in to it.

Amazon delivered mine this week too! Thanks Barry, looks like a great book!
