    Repairing Bobcat 773

    i just dont want to see people duplicating those mistakes and either costing themselves more money, downtime, or a lost-time accident. it's nothing personal. be careful, work safe, and ask a professional if you don't know what youre doing. if you're having a hard time doing something, there's...

    Repairing Bobcat 773

    especially when he admits in the comments section that there was a 50/50% oil/water emulsion in the chaincase. why did he leave it in there? not really sure why he slid the outboard bearing on the axle shaft before sliding it into the tube, then removing the hub to install the seal... why didnt...

    Anybody Experience with Shantui Dozers

    anyone who has burnt their pension and walked out of a shuttered factory would disagree that the lowest price is all that matters. every dollar is a vote, and to spend a dollar on a chinese knockoff when you know it's chinese and you could have a domestic article for a dollar and change, is a...

    Repairing Bobcat 773

    new chains arent going to break the bank, as atco suggested the carrier shaft is where you should be looking first but 900 hours of operation (i might question that number on a 2003 unit) with no lubrication is plenty of time to cause all kinds of havoc including stretched chains. price the...

    The End...or only The Begining?

    what bothers me about this feature is that if it levels the operator playing field, and the technology catches on, operator wages will nosedive. then you will end up with an unfair situation whereby a skilled operator is busting his hump on an older machine without the technology to match the...

    Pulling seized pins

    the one we used for this job was called an oxytherm system, cost about $1000. uses special rods which are copper tubes with five or six rods of dissimilar metals in the tube, then the ends are rolled shut. they stick into the gun handle which looks like a pressure washer gun with a brass collet...

    Hitachi EX270 mystery part

    it's some sort of positioning washer that holds the head of a bolt in a certain position while the pointer on the outside sits into a recess of the same shape to keep the bolt from turning out of position. last time i seen one of those was inside a john deere inboard planetary gear set.

    11 year old boy operating a 80 longreach excavator video safely

    never mind the "safety police" try putting in a claim for workman's comp or health insurance if anyone gets hurt while a kid is operating. and if someone else's kid is operating? kid sprains an ankle and tells mommy and daddy how it happened and boom, lawsuit. what will you tell the court? the...

    Excavator for George Jetson

    that video was created for investors who run like cattle toward shiny things and run away from scary things, not operators, contractors or mechanics who actually have a clue about excavators.

    Pulling seized pins

    thanks for all the support. one of the guys at the other branch caught wind of what was going on and sent up a hollow core cylinder, an oxytherm system with 3/8 rods, and i got to put the boom up on blocks. cylinders came out without incident. if you want to keep coming with suggestions i am...

    Pulling seized pins

    hi, sorry for not mentioning. The bucket is removed. The ends of the loader arms are resting on the edge of an empty scrap bin, the kind that is carted around by luggers. this one is the same dimensions as the V-shaped bottom ones, but goes straight down on the side the loader arms are resting...
