![]() The engine randomly spikes after stroking the controls and peaks for a few seconds to 3,400RPM. How do I adjust the model "SF" Precision Governor? Currently the idle is about 1400RPM(should be 800) mid-range is 1,500 and high is around 3,000. Who has the best pricing on JLG parts these days? My parts list is growing daily. I will be replacing the weather checked hoses. If the boom is mostly vertical it will stop. The whole machine shakes(pretty aggressively). What would cause this problem: When the tower boom is up and the main boom is horizontal(empty basket- I'm staying on the ground until repairs are made) the machine shudders(slip-sticking) when the tower telescope is being extended. I'll clean up the pads and post another picture of them. I hope the prior owner was not using it as a crane. I will replace the pin and both bushings. Also, the pin is secure and not rotating. I can't imagine a lack of grease would cause this? The bushing on the other side is in better shape. Like a tremendous amount of pressure smashed the bushing flat and caused it to deform and widen. You can't see it, but the other end of this bushing is the same way. What would cause the brass bushing to break apart and flatten out like this? No broken welds or other signs of damage. I will tackle getting the propane system up and running at a later date.īelow is the main boom pivot bushing. I don't know the history and there may be more missing and bad parts. It's a dual fuel machine, but the propane tank and several hoses and other parts are missing. It's taking me a lot of hours to get familiar with all of these parts since I don't know anything about this machine. Yes, it looks like the gas fuel lock in the parts manual. For example, how do you check and change the gear oil in the drives? The service manual is hard to understand because they talk about parts and pieces without any pictures. Is there more than one tilt mechanism? I'm guessing this should be repaired for safety reasons? The horn is missing along with the tilt warning light. What is the gizmo(circled in red) mounted to the left of the engine? It's disconnected. Would Costco AW46 hydraulic oil made by Citgo be OK to use?.What should I use for engine oil weight?.Very few below freezing days and a few days near 100 degrees. ![]() I live in the Willamette Valley in Oregon which gets 4 seasons, but is mild overall. I find the JLG engine and hydraulic oil charts difficult to interpret. ![]() Overall it's in OK shape for its age, but needs some things repaired. I just bought a 1996 JLG 45HA 4X4 articulated boom lift. ![]()
