HIYA well i drove out today to get some parts and came home with a massive log splitter....12 HP longer than my little truck and heavy! the guy wanted it gone, and $200 was the price. it needs a new engine, no problems because I have 2 of the exact engine that on it... easy part. its a vert well made home made thing, the neighbor guy said they used it and when they parked it, it was working ok. I dont see any oil leaks, I know the guy i dont think he would lie about it for 200 bucks... he wasnt even trying to sell it, i just spied it there in the weeds. anyhow, I want to drain the hydo fluid and clean it out, change the filter ect. engines I know... hydrolics, well I'm clueless. I will assume they pretty much are all alike functionwise. once I drain the fluid should i or can i even clean/flush out the whole hydrolic system? once I refill it, how do you bleed off all the trapped air? is there anything dangerous I should know before monkeying around with the system? what type of fluid is best? any help I appreciate, i will put some links to pictures of it if you all need em for reference or to see whats where. THANKS!!
