Chainsaw Repair

I've got an 019T disassembled waiting for an oil pump to arrive. Also have a Mac 10-10A that isn't automatic anymore apart needing oiler repairs. (waiting on ambition), And I have the handle off the Stihl 070 and am in the process of putting rubber on the tubing. I need to spin up about 3 chains too when I get a chance. Wasn't in the shop at all today. Maybe tomorrow... I did get some trees felled last evening. Good thing as it's very windy today.

Bustedknuckles when you install the oil pump in the 019T, two things
1) there is a window on the plastic case where the oil pump drive gear shows through the center of which is marked by being more roughly finished than the rest of the plastic, if the pump drive gear is not centered in that area the pump will not work.
2) when you install the pump using the screw you used to pull it out, be mindful of how much resistance there is to putting the pump in place. I have noticed that the plastic shrinks and the fitment of the pump is not tight enough to keep it in place. If this is the case you can wrap a little fuel proof Teflon tape around the pump body to get a tight fit. Don't cover up the inlet hole in the pump body itself OBTW if the pump was not centered in the opening the when you took it apart it would look s though the pump was bad when in fact it may not be. JMO from fixing the same saw four times.
