Message: <blockquote data-quote="JNT" data-source="post: 19542" data-attributes="member: 2129"><p>Hello, First post here. Great site. I just purchased a late 80's 743 that had the main hydraulic manifold/valve out of it. I have since had a new lift spool installed, cleaned and checked out by my local dealer. It is installed and everything seems to be working. The machine has not been run in more than a year. There was no fuel or hydraulic fluid in the tanks. The engine will puff white smoke then fire immediately with a half second shot of ether while it is being cranked. Fuel supply and glow plugs will be checked. I have learned here that the key turned to the left is the glow plug selection and not accessories like I had thought (aftermarket switch) I will try glowing the plugs for 10-20 seconds and see if that makes a difference (it has been around 50 degrees F when I have tried to start it) The hydraulics chatter while being raised but, silent on way down. The hydraulic fluid is foamy. I will try operating the lit/tilt while driving at midrange rpm's being careful to not bottom out the rams and see if that clears it up(per a rocommendation in another thread). I put in all new nipples on the valve body and had many new lines made; so air intrusion should not be an issue. I used standard hydraulic fluid (what I use in a Case 580 backhoe) to fill tank. I asked at the dealer yesterday what they recommend and they said the Bobcat brand Hydraulic/hydraustatic fluid is different. Will the "incorrect" fluid be harmful to the machine and/or cause foaming? Thanks for the help....any thoughts, advice or opinions are welcome.</p></blockquote><p></p>
