reinstalling crank hub and pulley, few questions?

i took the crank hub and pulley off with the pulley arrow in the straight up position (12 o'clock) i think or was it 1 o'clock hmmm
which ever way, the crank key way looked like it was at ruffly 1 o'clock
i know i should have marked everything

when i took it off #1 and #6 were at TDC and since then it has been turned over with the hub and pulley still off (adjusting rockers)

question is if i bring #1 and #6 back up to TDC then reinstall the hub and then the pulley (since it only fits the hub 1 way) it should be back to the original position it was when i 1st took it off right?
white mark on the hub pointing up and arrow on the pulley pointing up....
the whole front of the motor is assembled, cover, opti, waterpump etc. tearing that all off again really isnt an option but only a LAST resort

what is the best way to get the hub back on, i did a search and read something about an "all thread" what exactly is that? and how is it used for this purpose?
kinda scared now to use the wooden mallet and block of wood method
any tips/tricks/tactics for me?

thanks
Steve

With #1 & #6 @ TDC the hub should go with the pointer at 45° or at 01:30 o'clock position. The best way to install the hab is with an installer, but it's very doable with a peice of wood nd hammer.

the althread you read about is a 6-8 inch piece of hardened 7/16-20 threaded rod. You screw it into the end of your crank where you would normally screw the bolt in. Then you put just a touch of oil on your seal and then slide the hub over the protruding piece of rod. Start it on the end of the crank and then put on a big washer and thread the bolt on. tighen up the bolt and it will press the hub upon to the crank. when it starts to get real hard unscrew the rod assembly and install your balancer and bolt.

No, no. With 1 or 6 at TDC the pointer is straight up at 12 o'clock, the keyway is at 1:30.
