Looking forward to hear what others say about IHI. But if I can find the right machine at the right price.
Winter time isn't the best time to get one of these things as it would mostly sit. Would like to know what others have paid for an 80NX. I honestly think the machine is worth less than that, but I don't know. Sales guy came down on price from $31,500 to $29,500. The equipment place that is selling the machine was friendly and claims that he knew the owner. I have found a 2006 80NX near me (28xx hours), but it looks to have seen a hard life and there were no records for it. Would really like to know what people think that own or have run these machines. The 80 series seems a little large for most of what I'll be doing but I like the idea of the addition capacity that it would have. I've been doing some research and see that IHI makes a pretty nice "no frills" machines. I will use it for lots of weird projects around our farm and do some small logging duties with it. I've been looking for a mini excavator for quite some time now. Test wiring related to 2 speed and lockout lever with the test light while operating the machine.I've been a long time lurker, but figured that it was time to ask a few questions. If light stays on, move test light to wire sending power to pump solenoid from switch. Operate the machine, engaging/disengaging the 2 speed while driving the machine, monitor the test light to see if the power ever goes out when 2 speed acts up. Probe into a connector or terminal on the power supply to the foot switch with a test light. What I would do though, just to get a feel of what to do, is take the floor plate out so you can access the two wires going to the switch on the 2 speed pedal. Unless you have a wiring diragram it would be hard to follow how the power supply to the circuit is wired on the machine. Machines use connectors throughout the harness, I'd bet you have a connector causing a break in the electrical supply or something like that. I'm thinking you have an electrical problem, and the safety lever and two speed may share an electric supply circuit. I can't say for certain as I don't know your machine, but I'd wager you safety lever is electrical instead of operating a hydraulic diverter valve like on larger excavators.
Ok, safety lockout acts up at times as well. This should activate solenoid at the pump and make oil pressure come out of the line you have placed in the drain pan. Start engine and place safety lever in operate position, then select high speed drive. You can also test if high speed drive is getting pressure at the drive motor by removing the line that connects to the high speed control fitting on the motor and send that line to a drain pan. Check motor on other track in same manner. I can't remember the acceptable leakage amount, but I'd say if you're getting more than a 1/2 gal to 1 gal per minute out of that drain, may have a failed drive motor. Operate the drive for that side and monitor how much oil comes out of the case drain fitting. Swing digging bucket over the track that you're testing and use the boom/bucket to lift that track off the ground. Find some type of hose that will fit over case drain fitting still on drive motor and send the hose to a bucket or drain pan. Once you've determined which line is which, you remove the case drain line from a drive motor, and you'll need the proper plug fitting to block the disconnected line, else you'll have a constant flow of oil from the line. The will require the engine running and the safety lever in the operate position while working on the machine. You have to deterimine which line is the case drain and which one is the high speed drive control line.įirst of all, be very cautious performing these procedures. One is for the high speed drive, the other is the motor case drain. There are two small lines going to each drive motor. Checking the internal leakage of the drive motors isn't difficult, have to have a couple of things though to keep it from being a messy job.
