Why doesn't the installer work?
You could try putting it in the oven for a few minutes to heat it up, that will usually heat it up enough to expand it and make it easy to put it on. I have never had an issue with mine, so I have not had to do that.

hey irish, order a new keyed hub from cncmotorsports if your crank can be keyed. but what you have to do is get a 7/16 20 thread 5-6" bolt with some large washers. the bolt is hard to find. What i did personally was to use the origanal bolt and removed the washer and then got it finger tight.
I totally agree with you about this hub. my car sat for a week because i couldnt get the POS thing back on.

Do a cz28.com search for a homemade installer that a guy made. Basically its a threaded rod with some washers and 2 nuts to push it on. That way the pressure is on the threaded rod and not the threads in your crank. I started installing mine with the stock bolt until it wouldn't push it on any further. I'm going to take the bolt out and put the rod in once I get back to it.

its really not that bad to put on while the engine is in the car. I did it in under 10 mins. take a dead blow hammer. get the balancer lined up so it isnt on weird. start tapping it on. ull get it far enough use ur OLD bolt and thread it in by hand. after ur sure its threaded in a fair amount let the bolt pull it on the rest of the way. replace with new bolt and ur good to go.

And hope you dont rip the threads on your crank out. They make tools for this, always a good idea to use the correct tool for the job.

i had the motor out of the car but i took a hammer and beat on it and it slipped back on with some massaging, i agree though its the worst LT1 part by far, even over the opti. (only for people who have dealt with installing or uninstalling one of these)

I purchased the j-tool (j-39046) years ago and has come in handy many times. Comes off and goes on easily every time with no beating on anything. First time the hub ever came off I replaced it with a keyed unit.

the reason the crank pulley is hard to remove is because its a freakin lt1, the lt1 engine requires a special lt1 crank pulley remover. thats right i ran into that problem a couple of years ago when i installed my underdrive pulleys well i didnt do it i had a performance shop in tucson,az (thats where i lived at the moment) do it for me they had that lt1 pulley remover/installer. i dont know where you would find it maybe summit or jegs or gm direct. the pulley remover you rent from the auto parts store doesnt work i broke two of them..good luck
