Pre heating a Powermax piston on heat setting number 5,the piston cools as you slide the pin in,this requires further heating as the piston then re heats to regain temprature.
The polished steel gudgeon pin is fitted to a hot alloy piston,the circlips must still be fitted using a set of circlip pliers.
The new plus 60 thou, Powermax pistons fitted to a 1966 Singer Chamois Sport engine block (hillman imp) this is the maximum over bore an Imp block will go to without fitting new liners and pistons.The new piston set take the normal 875cc block out to 916cc.
