Oil pump replacement Husqvarna 137 

Very professional snd educational work!!! Good job

You dont want to put anything in the motor to block the piston... you can use a 13mm socket on the opposite side to hold the clutch from moving. This will prevent any damage to the piston

Hey there, great video. When I tried this technique it worked to push the tab back, but then sprung right back to where it started. Does it every time and wont click in. Any ideas? Thanks!

Kako je moguće da se uljna pumpa blokira od piljevine zar nema plastična zaštita sa druge strane

Cleaning the parts not necessarily. 😳

What about oilpump drive lubricating? Not neccessary?

очень грязно - мог бы хотя бы продуть.
