Nice explanation. I just bought a YM187D and I'm going through the fluids and changing hydraulic lines. ( had one blow yesterday ) I have yet to drain the hydro fluid and clean screen. Your vid makes it doable.
Since these machines were also painted green and sold as John Deere's, the fluid to use per the Yanmar/John Deere Specs is J20C. You might need to change the fluid again as the 303 doesn't protect the seals and will become 25% thicker due to use in time. JD303 was discontinued almost 45 years ago as an outdated hydraulic fluid. Plus, it has been banned in several states.
Not really, it's pretty straight forward. I would definitely wire brush your bolts down to get any build up that might be on them and to also allow your socket or wrench to fit tightly. Good luck!

Good to know. Thanks for the info
B maverick i would think the only way the oil would become thicker is if water gets into the system.???
Great video. I was not familiar with the screen, it didn’t look to hard I may try to tackle that... any issues to watch out for?

Did flushing it with diesel work out?
It did remove a lot of gunk. I'm going to change the fluid again when I get a chance with a premium fluid.
