[QUOTE="Sam_French, post: 27462, member: 2556"] Thank you all for replying. Here is what I have learned this week. I did not have bucket high enough when I pulled lift cylinder pins. I pulled the front pin out of cylinder on other side. I tried to jack up the bucket but kept raising the whole front of the machine up. I called Mike person who rebuilt it. He said put some blocks under the back to keep machine from pivoting. I put some blocks under the engine door frame. Had cylinder out in 2 min. Grease Zerks I used a 7 mm to take out zerk then 12mm to take out the main zerk body. Metric NAPA zerks are different from Bobcat. Threads are cut different also NAPA zerk is threaded deeper and will screw deeper in the pin. So I ordered new zerks from Bobcat of Antioch TN Zerks on the machine are painted and will not take grease so I am replacing ALL of them. If I can't grease the machine I WILL NOT run the machine. As far as hydraulic fluid is I will top it off and run it a little while. I will pull the chain case plug just to and check fluid level just to be safe. I am using AW-68 as Mike put in it. How hard would it be to raise the cage and pull the seat out so I can look deeper in the chain case? Again thank you all very much [/QUOTE]
