water pump gear
« on: March 09, 2009, 01:53:13 PM »
anybody have a good way to remove water pump gear from crank? i was originally gonna drill/tap and thread in a bolt for the slide hammer, but none of my drill bits would even scratch the surface. i then tried to weld a bolt and slide hammer out but the bolt broke. any ideas. thanks

motor is still assembled fyi, guess a fried crank seal is better than new crank.

You can get "cold spray" to test electronics.  I was going to suggest starting fluid (ether) but thought that might get really exciting, heating it up then spraying highly flamable fluid on it. Any spray with a cold propellant will work. If the popane doesn't work then Mapp gas it quite a bit hotter. Cam.

i bought several cans of dust off, co2 is the propellant so hopefully no big bang. also bought some welding pig snot thats supposed to protect against heat. also gonna make some sort of heat shield to better my chances. it all goes down tomorrow.
