Cmark's random photo thread

Cmark, do you have your own shop where you do machining? Do you have a bunch of employee's? Your work is impeccable!

Thanks for the compliment. Yes, I have my own shop with medium size lathe, milling, welding, component rebuild facilities. In the past I've had 5 employees, a couple of apprentices and some subcontractors to help out at busy times. I've scaled back a bit now though.

Very impressive the scope of work you do and in the quality of repairs. I have a slow hyd. leak and am dreading that I'll probably have to pull the belly pan again. The swing pivot repair I did with a boring head in a drill press is working great though.

Zero tail swing 314E. Counterweight off for everything. *facepalm*

From a maintenance perspective the best thing for that POS would be 5 gallons of diesel and a match, IMHO........

If it's only 4 bolts to remove the counter weight and you gain that much access if doesn't seem that bad.

Provided you have another machine available close by with the capacity to lift the 4-ton counterweight I'd agree with you, but on how many small construction sites might something like this be the only machine operating.?

Wasn't machinery supposed to become SIMPLER over time?????

Did a main harness on one of those. Even with the counterweight off it sucked.

Like Nige says the worst bit is smaller machines like this are used in the main on smaller sites on their own or with other smaller equipment, an idea would simply be to make it either hinge or demountable on a ram so at least it's self-sustainable

I wonder what kind of damage can happen when people put those weights back on and don't torque up the bolts properly.

Yup. 2100 ft lb torque wrenches are not part of the normal tool kit of most mechanics.

A 600 Ft lb torque wrench works with a 4 to 1 multiplier but how many people have that set up?

I thought that machine could doo a "Reach Around" on itself.....

Answers on a postcard to the usual address please.

Bigger machines have the ability to remove their own weights…

We torqued slewing ring bolts with 2 multipliers stacked together and I think it was 80# on the torque wrench. Was quite a job to hold all that up when tightening from the bottom. d.d.

 

[Welder Dave]

Yeah, you'd need a good sized loader or something else to safely lift an 8000lb. counterweight. You'd also need a helper. Machines like that should come with a way to more easily remove or at least move the counterweight out of the way. Hyd. or an electric winch maybe that holds it in place and then a few bolts that could be tightened with a 600 ft./lbs. torque wrench.

Surprisingly enough on the one I had to deal with one time, only paint damage. Found the bolts, cleaned the holes out and put it back on. Hyundai 330 from memory, fresh from the dealer.
