    tricks of the trade

    One thing I always try to get my guys to do (all 2 of them) is to coordinate your work so that it is easier on the other guy. It doesn't take hardly any extra time for the excavator to place downed trees so the dozer can easily access or push them into the burn pile and the dozer operator can...

    Sizing an excavator

    I have a Cat 311 which weighs about 26K. I bought it mainly for septic tank and storm shelter install work but have done some clearing with it. Right now I'm almost done with a 250 acre clearing project. Most of the trees were cedars, bois'd arc, ash and hackberry with the occasional pecan...

    Cat 311 Air Conditioner charging question

    The compressor was cycling on and off. During the off cycle the pressure was about 25 and when the compressor kicked in it went to about 40. The ambient temp at the time was 85. I even tried sitting the can on top of the engine with the hopes of raising the pressure in the can to allow it to...

    Cat 311 Air Conditioner charging question

    The AC on my machine needs charged and I can't seem to get it to take any R134. I have the full gauge set and after I hook up the low side I can read the pressure on the system but when I try to add freon it won't transfer. I've recharged my trucks with no problem but can't figure out why the...

    D5G tilt cylinder advice

    I tried every way to get the pin out without a torch and in the end I had to torch it out. I heated both bushings twice with no effect, welded a big bolt on the end and tried to beat it out with a BFH and then decided not to waste any more time and replaced the rosebud tip with a cutting head...

    D5G tilt cylinder advice

    Time for cutting torch yet? I got the parts today and tried everything I could think of to get the pin out short of the flame wrench and it would not budge. In the photo I have a 20-ton bottle jack under the pin and it would not move. I liberally soaked it with PB Blaster, tried to turn it...

    D5G tilt cylinder advice

    It doesn't look like the D5M setup. I know it will come apart easily as there is no more spherical part any longer. I'll let you know how everything works out. My field service setup is a bare minimum so if I can fix it then it shouldn't be too bad....(beat to fit and paint to match) For me...

    D5G tilt cylinder advice

    Thank you for the info Don! From the photo it looks like 1 each 6A and 6B is all I need.

    D5G tilt cylinder advice

    Yesterday when I was starting on a stock tank, I noticed the blade on the dozer seemed very loose and wandered back and forth on the tilt axis. When I checked out the connections, I found the tilt cylinder ball joint completely destroyed (the one attached to the dozer and not the ram end) and...

    Cat D6C auction find

    I don't have any insight to offer on your cat purchase as the only D6 I've run is a D6D, but I was in the same situation as you 30 yrs ago. I tried the college thing but after one year I decided that I would never be able to take sitting at a desk all day wishing I was outside. It won't be...

    Help needed for blown track adjustment seal

    Thanks for the advice. As usual, after great wailing and knashing of teeth, the cat parts people could not find the grey market part number so I am gambling that a 311B seal will work. I found the master pin with the keeper and will have to use a flame wrench to get the pads off. I'll try and...

    Help needed for blown track adjustment seal

    Thanks for the info mw. Do you have a recommended procedure to press the pin out? Does it take a special tool?

    Help needed for blown track adjustment seal

    It was one of those days today, broke a tooth on the excavator and my dozer operator let a tree get away from him and now I have two broken windows in the dozer. Near the end of the day, I jumped off the excavator and the track seemed very loose. When I looked at it, it was very obvious that...

    Proper Towing Rig

    When I bought my excavator I moved up from a single axle international 4700 towing a 20 ton double tandem to a semi-lowboy combination. During hard braking my dozer (D5G) on the double tandem used to push the truck and I really had to stand on the brakes to stop. I know I would not have wanted...

    Video of 150 year old railroad demolition by Excavator with hydro thumb.

    Nice work! Video well done! I've been thinking about getting a camera to add videos to my website. What software did you use to speed up the time?

    Does oil breakdown?

    Not sure why but the Rotella was priced at 17.99/gallon and the Delo at 12.99. I think I'll stick with what seems to be working. None of the machines use enough to add between changes and the SOS comes back good.

    Does oil breakdown?

    I was going to start a thread about oil but thought this one was appropriate. I've always used Shell Rotella in all my trucks and machines and buy it by the 5 gallon pail. Today while getting some filters for oil changes, I noticed that Delo 400 was substantially less than the Rotella. I...

    Parts manual page needed for D5G

    Thanks for looking up the parts Don. Looks like it will be a little more work than I first thought. I'm glad its not the AC compressor in the middle of summer!

    Parts manual page needed for D5G

    First photo is the assembly minus the lost twisted ribbon. Second photo is where the ribbon attaches to the brass fitting. I'm trying to determine if the twisted ribbon part can be ordered or if one must buy the complete assembly.

    Parts manual page needed for D5G

    Does anyone have the parts manual exploded drawing for a 2005 Cat D5G dozer on the environmental controls. My temp control knob started to spin freely and not control the temperature so I removed the panel to have a better look. I lost the "twisted ribbon" metal piece into the bowels of the...
