Ok Rodbolt, got it apart so I can see a pin with inside thread on top and a pin in slot. Looks very badly corroded. Pored gogo around top of pin, will have to fashion a puller using threads. I can only get heat to top, can't reach bushings. My unit not like anything in in the maual. The drive shaft housing and power head mounting base are a one piece casting and the pin doesn't look like anything in the manual that I can see! I had to remove the four dyna-float locking rubber mounts to move drive shaft housing and get at tiller braket and pivot pin Any more advise.
