I have to remove a pair of Hydromatic Hamilton Standard props from the R2800 engines. I am trying to find what specific tools are needed to remove the props. I have found a list online of all the tools needed for taking the props off and apart. I need to know what tool or tools are needed once the dome is off? Any assistance is greatly appreciated as I want to be able to show up with everything needed on hand to do the job. Thank you.

Welcome to the forum. A little about your self and the aircraft you are working on would be welcomed by most members.
If you go to the thread Manual Index - American any Erection and Maintenance manual for any aircraft that has Hydromatic props will give you the details you need. Note there is a locking screw that must be removed before you can undo the dome retaining ring.
Today I am getting an error message for every link from the above web page. Had that problem not existed I would have given you a specific link.

Thank you I will take a look. I am actually removing engines and props from a newer aircraft, but since these were common engines across older models I thought I would try here. Fairchild C123K, Aerial Visuals - Airframe Dossier - Chase C-123K Provider, s/n PNP-022 PNP, c/n 20144, c/r N8190B

Thanks for the background. A nice addition to the collection.
she appears rudderless in that last photo. It is a common problem to get rudder damage in storage. I know it was put to rights and ferried to the new home, but I wanted to comment on that.
It is hard to block them both top and bottom and a big wind exerts so much force across the rudder in an unnatural way.

The C123 props look similar to the Canadair CL-215, 43E60's. The basic order from memory is remove the dome cap and remove flyweights if installed, and then the oil tube. Remove locking screw from the dome nut, and then the dome. Remove the serrated locking piece that goes between shaft nut and the oil transfer unit, you will need a 10-32 screw to get the lock out, after removing the locking ring. Remove oil transfer unit, you would need the long round wrench with the internal serrations. There may be a locking pin on a thin metal strip that goes through the inside of the engine shaft into the propeller retaining nut. You would then need the long round wrench with the external serrations to remove the propeller retaining nut. This is a very high torque nut, so you may need a torque reducer to break it loose. Wind the shaft nut out until you break the propeller loose from the cones,.

If the engines were ever run with those props on there, be prepared for lots of oil coming out of the dome and have several big buckets on hand and a way to suppor them before you crack anything loose.... BTDT and had to clean up the mess.... 
The dome is very heavy and really should be a two man operation during removal. You will also need a pair of long endless slings to crane the props off.
