jeroen_decker Posted June 18, 2013 Posted June 18, 2013 Hi there, I just picked up a Chappy LB50 that had been severely abused. I pulled every single component of the bike apart for a thorough cleaning and inspection. When putting the oil pump back together I had a washer left over (this is never good). I checked all the part schematics but none of them show the internals of the pump (when you get to the plunger and spring mechanism). I am looking for someone who has pulled the oil-pump completely apart (or has an old pump and willing to pull it apart) and can give me some guidance on where this 1/2 inch washer might fit within the oil-pump chamber. The hole of the washer is about 1/4 inch. When I slide it against the plunger wall next to the spring the pump no longer rotates when tightening the bolts. I appreciate any help. https://www.dropbox.com/s/oprvcxslo7rqb6m/Chappy02.jpg Thank you, Jeroen
jeroen_decker Posted July 1, 2013 Author Posted July 1, 2013 I found another oil pump and confirmed that the washer slides over the plunger before the spring. I can only deduce that I tightened the bolts unevenly which put pressure on the internal workings of the pump.
