Gt750 block pulling inserts
Just had crazy idea. As the main head bolts are quite thick could a machinist make inserts with a shoulder that would install from below head with 1/2" internal threads so we could just use an old head as a block puller. These could be cnc fairly easy and help a world of gt owners. Or am I just crazy. My machine shop has two of my engines with no hope of getting blocks off.

Re: Gt750 block pulling inserts
Have not done this myself. Have seen rebuild topics where they use a flat plate to pull the head off.
A simple design & pretty easy for a shop to make.
Am busy. Will look for the info when I can if someone else doesn’t provide the links.

Re: Gt750 block pulling inserts
Oh I have seen the block pulling plates but to ship one or build one would be costly. I just thought this idea would be easy to ship and help gt750 owners worldwide.

Re: Gt750 block pulling inserts
Not sure what exactly you have in mind. If you make a sketch someone might be able to provide some insight into how well it would work.

Re: Gt750 block pulling inserts
Those look simple enough. So how would you use them?

Re: Gt750 block pulling inserts
Pull the head and install between block and head. Re bolt head to block and use 7/16 bolts to push down on studs lifting block off.

Re: Gt750 block pulling inserts
Interesting.
That could work for the T500 as well. The GT750 & T500 nuts look similar but have different part numbers.
I have a T500 restoration in the queue. Some PO used sealant of some sort where the base gasket should be. So removing the cylinders will be a PITA.

Re: Gt750 block pulling inserts
Be careful to lift them a flat at a time, or the head might be distorted.
Think of how stupid the average person is, then realise that half of them are more stupid than that.
