mr broke....what you call a wedge, i call a collar, that being said I would prefer the splined one from perkins. make sure you torque the main bolt to 300 ft lbs+ (check that spec). getting back to the damper...on one of the faces there is a finger nail sized steel circle, which is the fill point for the "oil". what happens over time is the "oil" leaks out and vibrations occur. that is why the front pulley "walks" off the crankshaft. the rebuilder for those is dale manufacturing good luck

Looked over mine and it has two round protruding "pegs" about 5/16 wide and placed exactly opposite of each other on the face of my balancer. They protrude from the face of the balancer about a fingernail thick if thats what you mean. I'm guessing they are pressed in as they do not have any means of backing them out and perhaps there is or was liquid in there at one time? When I shake it it feels like no liquid is present in there. I am trying to educate myself on the design of this part. Hopefully the Perkins dealer can get me fixed up. Thanks for the info on the repair shop if I need to go that route.
