Crank pulley Bolt..locking down engine tricks
so I'm replacing my front crank seal and Im at the point where I'm removing the crank pulley bolt and need to lock the engine down from turning to get he bolt out... after much research and printing of tips/tricks on the forum.. it seemed the threading of a bolt through the torque converter was the way....I did this and with minimal pressure...that just sheered the bolt off... so while I now drill that bolt...im looking for either the proper or better procedure.
as always many thanks

I just removed my rad fan setup on my S55 and with belts still in place I "shocked" the bolt by hitting the ratchet sharply with a "dead blow" hammer multiple times......it eventually gave way......maybe not for everybody but it worked for me.....

Hmm...I could put my belts back on and see if that will provide enough to hold...I've also read to put a flat Prybar wedged into the hole where the flywheel is when you remove the dust cover and that will wedge things from turning.....apparently I did not think to use a hardened bolt when I tried that method ...lesson learned...bUT now I'm wary of trying that process again....don't want to drill out another sheared bolt...

Find somebody with the correct MB tool or rent it , not worth the hassle of messing something up,you have to torque it real tight when done anyway,and be real carful lining up the balancer on re assemble with the short bit of key way they give you to do so.

The MB balancer holding tool (shown above) works great if you have access to one ... however, It does not work on aftermarket pulleys (in my experience).
Another way to go is the Miller flywheel locking tool ... I have one and it works like a dream (but requires you remove the starter motor). Reasonably priced at $40 or so.

1-borrow a holder
2-apply a thin coating of grease to the inside of the crank pulley, this will make it slide onto the key way with no effort
3-no grease on crank pulley seal
4-torque to spec
5-mark crank bolt and pulley with white paint
6-torque until the white mark on the bolt is 90* from the white mark on the crank pulley
i would not trust a flywheel holder, bolt, or any other tool to lock the flywheel in place. those are meant to hold the flywheel when torquing the flywheel bolts, not the crank pulley bolt.

I have found out the hard way on many projects to just stop work and wait... Or you spend way too much time cleaning up messes.
Get about $80 worth of hardened bits good luck getting that sucker out. At least it is easily accessible or at worst you can rip the Trans out in 3-4hrs.

I would like someone's name on the install for the fact in case it ends up being the 1 out of 3 that fall off :-/
Is it under advisement to get in on, locked down to spec then to another shop to complete/verify install. Hell, pay them to remove new ARP bolt, install weistec keyway kit reinstall etc... That is what I was planning on anyway.
I have a 185cp to put bc the factory CP is separating (trying no to thread jack )... need a little direction too if possible.
I have a performance shop who just put a kleeman race motor m113k with drysump etc into an 06slk I was going to use and I guess for insurance claim purposes I would like to have someone else responsible for all the damage when/if it is in the 33% failure group. Hate to be a pessimist just being realistic.

Be careful if you hold it from the flexplate.. crank pulley bolt is on pretty tight and flexplate teeth may easily break if you pry against them

the fit was perfect so the wheel does not move a spec...the bolt actually came off fairly easily with my breaker bar with using my jack handle for an extension... no big deal.... now to put it all back together !
