Not pumping??
When you do put it back together, make sure the arm of the pump goes UNDER the eccentric.
I have seen them stuck in and the people wondered why it wouldn't pump. Because the arm was on top. :banghead:
Oh, and blue.
As long as you have the hollow bolt for the cam retainer (upper left) the dripper and an oil slinger you should be fine.
If there is a slinger there, on the crank snout, pay attention which way you take it off and put it back the same way. Some folks pull it and then can't remember. lol
