Interesting comment Brian, must admit I was in the camp that thought a very wee clearance was required before using loctite. Do you have the loctite number for press fits, I will get some in! Nice piston rods Pete.Chris
If it were me I would try to leave the flange on the crank pulley and remove the flanges on the 2 cam pulleys. You really only need the flange on one of the pulleys and it probably doesn't matter which one has it. My thought is to keep the flange on the pulley driving the belt. Unless the cam pulleys are misaligned (highly unlikely) the belt should track around the cams without any trouble.
