    Tilt bucket cylinder bushing source

    I picked up an old SEC tilt bucket that needs some welding/pin/bushing work. The worst bushing is the rod end on the cylinder. It's not terrible but I think it'll translate into extra slop at the bucket. It appears to be some kind of Teflon coated bushing? Any idea where the best place to source...

    EX60 travel issues

    So my machine sat most of the winter and I was out using it today and noticed some things that were working just fine before aren't now. 1. Tracking the machine doesn't disengage the auto idle. 2. Travel speeds don't work Machine works just fine aside from those. The control levers disengage...

    How do I install this door glass?

    Trying to figure out how to install new sliding glass in my EX60 door. The frame is rigid and I'm a bit at a loss. Does the rubber center need to come out and somehow be slid around it after?

    Groove on seal surface in center joint. Cause?

    I've been having an issue with my track motors and narrowed it down to my Center joint was bypassing an excessive amount of oil through the case drain. I have put new seals in it already and I don't know how I didn't notice these grooves but I'm pretty sure they are the culprit. What would cause...

    Final drive irregularities - EX60-2

    I’ve been clearing brush on a steep lot for the past week and a half and noticed some weird action while tracking around. I’ve noticed that every once in a while a track will act like it’s jammed. Motor lugs down, motor goes full relief but it barely has any power. If I let off the pedal and...

    EX60-2 throttle servo noise

    I just rigged up a bell rank so my throttle motor now works with my engine swapped excavator and when turning the key off the servo motor jumps. It's like it's bouncing off a stop before hitting a limit switch. Am I on the right track?

    Understanding Max Pump Flow

    I am trying to size a motor to plan a brush hog build. I've attached an image from the spec sheet. Do I double the GPM or or is 20.9 GPM the max flow?

    EX60 swing gear seal gone aleady?

    I've got about 10hr on a newly sealed swing gear box and I just noticed this seeping out. Checked the dipstick and oil doesn't show on the level. I haven't checked it since I filled it. Is it all common for these to use any oil as they settle in? I doubt it but hoping I don't have to yank that...

    Need to make engine run hotter. Ideas?

    Some of you may know I have an EX60-2 with a 2.2L Kubota engine swap. The original engine was a 3.0L and the original cooling system is in use. The problem is I can't get the engine to build much heat. I ran it for 3hrs straight today in 38f weather and the thermostat housing was reading 120 and...

    Spinning hydraulic pump faster?

    My machine has has a different engine swapped in that makes its rated power at 2600RPM vs the OEM engine at 2200RPM. Is it fine to spin it faster to stay in the meat of the power or should I run it lower? If it's fine for the pump I should just expect faster movements right?

    Hitachi EX60 Light/Wiper Switch Panel Dead

    I have no power on the 4 button panel under the gauges That operate the Lights, Wipers, Washer and Buzzer Silent functions. It seems as though there just is no power to the panel. I'm not sure where power is supplied from. I've got the panel somewhat torn apart but came up empty on getting...

    EX60 Power and Travel Controls not functioning

    The previous owner tipped the machine and subsequently ruined the engine. He replaced it with a similar power Kubota engine and converted the throttle to a manual lever bypassing the computer control. I'd like to see if I can get it all working again for a few different reasons. The main reason...

    EX60-2 Thumb Circuit

    I'm planning to add a thumb to my EX60-2 and need a hydraulic circuit to run it. I'm thinking of using the unused offset boom spool. It'll require me to fab up a pedal and run a cable to the spool since it's not hydraulic. This seems to be the most fool proof way but it will be pedal actuated...

    BD2G Steering Brake Issue

    I've got a new to me BD2G DD dozer that is acting up. When I pull back on the steering levers, the clutches work properly. I can stop the machine by pulling both of them and they work smooth. The problem I'm having is the brakes work very sporadically. Sometimes they lock up great and sometimes...
