![]() My best guess is, that even Check point support is puzzled by this, I have spoken with them, provided dumps and maybe all available logs. Traffic is permitted in rulebase, other time it works flawlessly. During that time, no backup is running, no policy update, routing is static and rather simple (default + directly connected), no drops in traffic logs, CPU 15% max. This is randomly visible in dumps many times from midnight to 2AM and then. Such behavior is for 10 or even 30 seconds, many timed during two hours time window. We are observing clearly retransmissions, so packet arrives to external, but it is not forwarded. And really, we are able to identify, that on outside interface in given time we are observing packets, which are not visible on internal. Initially hard to believe for weekend we have switched off fwaccel and setup tcpdump on internal and external interfaces on one of virtual system. To make story short, a customer started to complain, that every Sunday and Monday around 0:10AM is observing on monitoring traffic drop. I just run out of options and even opened support case, but so far no luck. Call today so we can find the right final drive or hydraulic component for you, or check out our online store to find your O.E.M. Texas Final Drive is your partner in providing new or remanufactured final drive hydraulic motors from a single mini-excavator to a fleet of heavy equipment. If your final drive motor seems to be weak, be sure to eliminate high speed mode as a potential cause before you assume it is a final drive issue. High speed mode won’t allow them to generate the same torque as they can at slower speeds. Final drives will behave as if they are weak when they become trapped in high speed mode. Just because final drive seems to lack power doesn’t mean the source of the problem lies within the final drive. Pilot pressure should be similarly simple to check. It’s not uncommon for something to get trapped in the linkages and cause problems. Control linkages would be the easiest thing to check first. If your machine uses mechanical controls, then the speed control would be adjusted by control linkages and pilot pressure. Depending on your skill level in electronic troubleshooting and repair, this might be a job better left to a professional. If you’re lucky, the problem might just be a loose wire or a loose connection. You may need to track down some wiring diagrams and additional equipment to pinpoint why the speed mode isn’t working correctly. For example, if your machine has electronic controls for travel and speed, the problem may be an electrical issue such as a relay, solenoid, or controller. Fixing the ProblemĪfter you've identified the problem, the solution will vary based on what type of machine you have. If performance doesn't change, there are some other things you can checkbefore sending in your final drive for evaluation and repair. ![]() The easiest way to determine if your final drive motor is stuck in high-speed mode is to temporarily disconnect the two-speed line to see if the performance is altered. The result is a final drive that seems to be weak. If your machine is in high speed due to an issue with speed control, it simply cannot generate the same torque that is available in low-speed mode. Remember that speed and torque are inversely related: an increase in speed (high speed mode) will reduce available torque. This is a problem with the speed control system, NOT with the final drive motor! ![]() In high-speed mode, even a perfectly healthy final drive may have problems trying to generate enough torque to move a significant load or drive up a steep incline. If so, there is a chance that it is trapped in high-speed mode. If your final drive seems weak, check to see if it is a two-speed model. Why High Speed Mode Mimics a Weak Final Drive In this Shop Talk Blog post, we are going to talk about why high-speed mode can be a problem and what you can do to resolve it. Even though it makes your final drive seem weak, it isn’t really a problem with your final drive. If your machine keeps steering to one side or has issues trying to climb an incline, one of the final drives may be trapped in high-speed mode.
