older roller lifters

[john kunsak]

they sound like the crane lifters i used in the 80's. the springs that were used in the lifters to position the tie bars in the lifters would push the lifters away from the cam & they would not touch the base circle of the cam &i felt that was why i had a few failures on even low use lifters until i installed the crane rev kit springs& plates to keep the rollers in constant contact with the lobes..i think the axle shafts were hollow that failed.
