Default New harmonic balencer.Pully assembly install ?

I'm just now got the new HB or pully assembly installed and I have the pin in it, do I need to use any thread lock on the ARP crankshaft bolt ?

Nope, Blind hole. Torque per ARP with their lube.
240 ft/lbs off the top of my head, with the ARP lube on the threads, faces of bolt and washer.

I snapped an ARP head stud once and called them and they said "Did you put oil on the flat part?" I said "No, that's not in the instructions." They said it was a must. I only say this because it was not in the paperwork. Prop_Joe said it. I am just trying to impart importance.

Strange they told you that, because only the stud threads and bottom of the nut get lubricated with ARP ultra torque for studs. The washer goes in dry.....and that is in the instructions.

OK, I need some guidance, Now how do I hold the crankshaft in one place as I tighten the APR Crankshaft bolt ?? There isn't a flywheel to lock it up with ?

I have a tool from Summit Racing that I purchased to hold the crankshaft while tightening the harmonic balancer bolt. Other option is to purchase a flex plate holding tool which requires removing the starter to install the tool.

What are you trying to communicate? The engine is on a stand? You have an auto transmission?

You might check with autozone and ask if their harmonic balancer installer rental tool kit has the locking tool as part of the kit.

I'm assuming you have the proper tool that presses the balancer onto the crank already? That being said, Depends which dampener you have. I installed a Fluiddampr and had to use the one with bolts on the hub of the balancer. If you have a stock stye HB with the three slots there is another you can use.
Bolt on style:

Tool bolts to the front of the hub of the HB
Tool bolts to the front of the hub of the HB


Three pin design for oem/stock balancer:

OEM or stock style

You can probably rent a tool at Auto Zone. Many times you can purchase the tool and return it, in essence a rental. I just did this to use a steering wheel puller from Auto Zone, when done, I returned it and got a full refund.
