I have a L3560 HST Cab with LA805 loader and BH92 Backhoe. FEL works fine. The boom on the backhoe is very reluctant to retract when fully extended with dipperstick also at full reach, without a load in the bucket. When partially loaded, the only way the boom will lift seems to be if I curl the bucket and retract/drag the dipperstick back closer to the machine. Dipperstick and bucket seem to be working fine. Swing is also okay. Stabilizers are good although seem a little less able to lift the back of the machine than they initially could.
The backhoe was "used", sat in the dealer's lot for ??? (maybe a year or so. Original owner traded it in on a snowblower, had purchased the BH in 2015). The dealer installed a hydraulic thumb which seems to work fine, although with the weak boom it hasn't had much of a workout. When operating the bucket and dipperstick at the same time, they both move at the same time. Anytime the boom function is engaged with any other function like swing or dipperstick, the boom just stops responding. Needless to say flat, level trench bottoms are a real challenge. HST fluid is in the dipstick range and machine has just over 20 hours. All grease fittings have been greased twice. I changed the bucket from a 16" digger to a 24" ditching (no teeth) bucket and the extra weight of the bigger bucket is noticeable on the boom function. All functions seem to work at initial machine startup but as it warms up, the boom malfunctioning is more evident. The cylinders seem to get warm but not really hot.
Any suggestions and insights are greatly appreciated. Thanks.
