    2005 Z60 Cranks no start

    55002 so I am using the 75861 but it appears to be not matching what I am seeing.

    2005 Z60 Cranks no start

    Went with a crank position sensor and I am not surprised that I still lack spark.

    2005 Z60 Cranks no start

    Greetings, We have a Z60 dual fuel LGR-425 that will crank and not start. Last week it came back and was put in its spot. I needed to move it and it cranked fine but no start. I have a sweet buzz from my fuel pump and no spark with my tester. I pulled flash codes and got a 1-2-3 for as long as I...

    450A Bang Bang functions not working

    I finally resolved the platform issues. In diagnosing the original problem the technician switched the swing and the tower cartridges. The swing dumps back to tank in neutral and the tower and telescope do not. I have adjusted the reliefs on the swing and I have good pressure at the block. I...

    450A Bang Bang functions not working

    Well the valve (IF available) is more than twice what I thought. The tear down and inspection of the valve did not uncover anything. All valves had their O-rings and seals. I did find an internal plug and sealed it. It was tight. All passage that were visible looked clear.

    450A Bang Bang functions not working

    Damn it man. I told the owner of the machine I was going to remove the block put it on the bench and remove everything on it for cleaning and inspection. At the end of my rope and out of options, I called yesterday for a price on the main block and the block is sold as a complete assembly. I...

    450A Bang Bang functions not working

    That is correct. The telescope appears to have a demand that is less than the lift so it gets priority. I tried all combinations today and only tower lift combined to the other bang bans will get them to work.

    450A Bang Bang functions not working

    I went and tried all the possible combinations. Only the tower selection gets the bang bang functions to work, from ground or platform. Steer will only steer drive only drive. Selecting two bang bang functions at once does nothing.

    450A Bang Bang functions not working

    The way I explained that last part was confusing. I see main lift in the operation manual and upper lift in the parts book are the same. When operating the main lift it works however; working a bang function along with the main lift only the main lift works. When working the tower lift we get...

    450A Bang Bang functions not working

    Here is what I have: From the platform it will drive and steer. I was working on the issues from the ground control to keep it simple. I am using platform right as my go to bang bang function to be consistent. At G2 Platform right at idle 200 PSI no movement. Power up pin 11 to get high idle...

    450A Bang Bang functions not working

    I just switched the load sensing shuttles and then I went through each coil to see if any coil in addition to the function selected are pulling in the cartridge and I found nothing out of the ordinary.

    450A Bang Bang functions not working

    I swapped the lift and steer sequence valves. (again)Nothing changed. Next I removed P1 input to the manifold and capped it at the manifold and ran P1 directly back to tank. I wanted to see if some type of pressure was corrupting the P2 side. Nothing changed. Then I removed the level coil from...

    450A Bang Bang functions not working

    That is a great break down. I have no psi with the engine running and nothing selected. When I power up pin 14 I get 2,800 psi. I had a can issue on a roll off to resolve so I had to walk away the rest of the day. I pulled the shuttle and it was clean and I could push it back and forth with a...

    450A Bang Bang functions not working

    JPV Bang bang is the way the JLG pioneers describe the functions that are switched on or off. Some controls are proportional like the boom while others are either on or off like swing right. The latter is just on or off and called bang bang.
