Komatsu D38E-1 Pops out of Reverse

The machine pops out of reverse but all the pressures are good. It doesn't matter which range it is in. Machine has a joystick control for direction, range and steer right or left. When in reverse it seems to me that the control has no detent left and easily pops out of gear. I checked the parts book which only shows a detent for the range selection. Basically turning the handle changes the ranges. There is nothing shown on the spools for direction. Looking at the diagram, it looks like only...

580C light brown leak from right brake to case

I just got done replacing the Master and Slave Cylinders. I sprayed a lot of brake cleaner and it just rained here. When the brakes are applied the wheels will stop if they are spinning off the ground. I pulled the diff lock cover to free up the diff lock input shaft and found what looks coffee light leaking out of the right brake where it mount to the differential.

I checked the diff oil right away. The oil is good and clean. The brakes haven't been moved in the long time. It also...

Where is Case 580 Super L Rear Differential Part Number ?

I am going to change the fluid in the rear differential and planetary drives on my Case 580 Super L Backhoe. I found a reference that says the oil requirement is different depending on part number for the rear end on these machines - Axle Numbers 114367A2 and 114367A3 use MS1317 oil which is and 85W 140 with friction modifier. Axle numbers 114367A4 and later use MS1207 which is a HyTran Fluid.

CAT 299D3 XE

Can anyone help me with understanding what a step pump is and how it would de rate the motor into limp mode on a 299d3 without throwing a code?
I’ve been having nightmares with this new machine from one problem to the next and now I’m told it’s the step pump and it “MIGHT” be covered under warranty. This is a 2020 with 72 hours on it so I’m getting concerned with my CAT

Cat 955 L

Hello to everyone, i am a new member to this forum, but i have found much help in the past in various posts.

I Just purchased a 955 L. I dont know the date of the machine, there is a small plate welded on the engine side of the "dashboard" that reads 8Y8710. Is that the serial number?

The loader has been sitting for two years due to cylinder head failure, combustion was leaking in the cooland circuit. The previous owner took the head out but never got it fixed.
I Had a look at the...
