No bar oiling

Difficulty

Time
15-30 minutes
Tools Used
Screwdriver, Torn, piston stop, clutch spanner
Removed clutch.
Removed oil pump
Installed new drive gear, one-piece oil pickup pipe, and new oil pump.
Reassembled and tested. OK.
FYI. The old pickup pipe was two pieces which I ordered one of each. They both superseded to the single piece pickup pipe. The order did not reflect this and now I have an extra. Anyone need a new-style single piece pickup pipe?
