Parts Used
Removed shroud and then spark plug. Made sure piston head was bottomed and then put rope in cylinder and then but wrench on clutch and took it off the shaft. Removed large washer and got to pump and removed old and replaced with new. Reassembled in reverse order. Filled with gas mix and bar chain oil and started chainsaw up and all worked great. Pump worked great so went and cut down a tree!! If you don’t understand this I advise you go to UTube and watch your make and model being repaired.

Oil pump stopped working.

Difficulty

Time
30-60 minutes
Tools Used
Screwdriver, Pliers
Parts Used
Basically had to disassemble the chainsaw to access the little oil pump. That was no problem, but after undoing the two screws attaching the pump I had to pull the two small little plastic oil lines loose. That was like doing open heart surgery, but after a little time and a lot of patience I managed to get it all back together and the saw and oiler are working fine now.
