Ok I can confirm that a Powertorque module will work fine on a full crank. I just fitted one on a full crank 550 and it works fine. The next thing is does anybody know how Victa set up the blade carrier boss on these, I have not come across this before where it is held on by a bolt up into the crank similar to a Briggs fitted on a Victa. This is self propelled so it has the drive belt running off the shaft. I wasn't going to pull the motor off because a mate wants it and that is why I pulled it out from the garage, but I think it might be important for future reference if I take some pics of it. I also had a bloke drop a 550 in last night and that was fitted with a standard Powertorque and this is probably why this one is not self propelled. My thoughts are they probably put an extension boss on the crank that incorporated the drive pulley and probably lifted the motor up on spacers to suit to keep the blades at the correct height?
