snowmobile02067 Posted July 2, 2013 Share Posted July 2, 2013 I was not sure whether to ask this in this or the antique forum, but I have a flathead mack question. I am tearing down a stuck EN377 and got the crankshaft out and am now working on valves and pistons. My big question is the distributor drive shaft. With the oil pump off, does the shaft just lift up or is there any pin or something that holds it in? Mine is quite frozen, as in it doesn't spin, but I do not want to break anything. Thank you Quote Link to comment https://www.bigmacktrucks.com/topic/31778-en377-distributor-shaft-removal/ Share on other sites More sharing options...
j hancock Posted July 2, 2013 Share Posted July 2, 2013 Been a loooooong time, but my recollection is the shaft should come out the top. Soak it with penetrating oil and GENTLY tap with a brass punch from the oil pump side toward the head. Quote JimIt doesn't cost anything to pay attention.
