Got excellent dealer service to repair a bad seal in the backhoe ram. As explained in an earlier post, even with the engine running the backhoe would slowly drop.
Once a new seal was installed, all was well. But, after a few hours of digging, the problem returned. Another call to the dealer. The factory asked that I warm things up well, then extend the backhoe and turn the engine off. They wanted me to measure how many inches the ram extended (bled down) after ten minutes with the engine off. The measurement was easy. It had bled off the full extension of the ram after only 5 minutes.
I reported this back to the dealer. Fortunately, the hoe is useable although its a little annoying that it moves on its own. I'm waiting on word back, but the guess was that they might want to replace the entire ram. I'm not a mechanic, but I'm wondering if there is something internal that is scoring the seals and causing them to leak.
