my linkbelt 2700q had a cab fire and I need to move it and load it on low lowboy. is there any way to unlock the brakes with out disassembling the final drives. thanks
The only way I know of is popping the covers off the finals and pulling the sun gear out, then put the covers back on. I'm not familiar with Linkbelts finals, but most machines can be moved dead this way.
Thanks mj that's what it looked like in the parts book. Its got hydash finals. Same a Case 9020b.
The amount of work (and mess) involved in tearing down the drive motors to release the finals is considerable. I'd sure try the easy way first. The amount of mess from oil spill is much less and easy to contain. Good luck, cab fires most times salvage the machine. Hopefully you can find good used components to keep costs down.
the insurance guy came out to day so wont no if its totaled for a day or two. but I would like to move it out of my way. so if I pop off the covers on the finals pull the sun gears she will roll.
disconnect the oil lines to the tracks, connect them to a different hydro source, maybe a skidloader. use the skidloaders hydraulics to walk the hoe wherever you want it.
The easiest way is to remove the bolts on the drive sprockets so they free wheel on the hub. No mess, no fuss and replace them when you need to.
just fyi maybe your brand is different but our deere 350d burned and we just popped the final drive covers off and pulled the axles out piece of cake put the covers back on and pulled it wherever we wanted to
I have done what Tones said for a short movement. worked alright.
On this model, by far the easiest is to pull the center sun gear in each final (as others have stated) This has a GM24 Teijin Seiki, aka HY-DASH. stumpjumper83's suggestion is what we will do if a machine is in the brush. We found it was easier to crawl it out than to drag it over a distance. There is much more preparation required for this method, but it does work great!
thanks for the help. I ended up pulling the hole planetary out. sun gear had a ridge on the back and wouldn't pull out. when we pulled on the sun gear the hole planetary pulled out.
Hate to see the fire damage td15c . Now that you have the excavator where it will roll free will the plan be to get the boom folded up & winch it on the lowboy ?
stumpjumper83 method: (disconnect the oil lines to the tracks, connect them to a different hydro source use the skidloaders hydraulics to walk the hoe wherever you want it.) where would you connect the hydraulic lines on the skidloader?
Aux. hyd's usually on the loader arm of the skid steer. Steering would require some creative thinking though.
Thanks, would a smaller skidsteer be able to make a 15 ton excavator move? What about the brake on the excavator, how to remove it?
What make & model exactly of excavator are you talking about.?
hitachi 135
You'll need someone with knowledge of JD/Hitachi in that case. If the brakes are integral in the travel motors removing the motors completely would allow the machine to be towed. The downside is that if the ground on which it's being towed is not level there is always the possibility that the machine could run out of control.
^ my 120 carbody was easy to pull with the mini. I could see that getting away from you!
i dont want it to be towed i want to find a way to power the final drive with external hydraulic and remove the brake and yes it will have to climb a hill so i need to be able to put back the brake on if anything happens.
I will defer to those with specific JD/Hit knowledge but I will say I have never come across a procedure to move a dead excavator using an external hydraulic source. That's not to say it's not possible. The usual way of thinking in the circumstances you are facing is to use a much larger machine than the failed excavator to do the towing and oversized everything in the towline, shackles, etc, dept.
unfortunatly i dont have access to a bigger machine.
Why do you need to tow ? Major engine failure? Electric fire? Hydraulic failure? Please remove cover from inside final post pic of travel motor area.
Similar to this one
Sorry couldn’t see clear enough. Basically need to know how many hydraulic lines are in that housing. 3 probably has brakes internal to motor or requires motor to have hydraulic power 4 probably has brakes internal to final housing that line can be pulled and pressurized with ports power to release brake
There is 3
So pop final cover pull gear reinstall cover and tow will have no brakes. To hook another machine up hydraulically will require a fair amount of redneck engineering
maybe there is a redneck engineer around!
https://www.stuff.co.nz/national/11...k-in-mud-cant-be-moved-because-permits-needed This machine was driven out with the aid of another machine and a powerpack connected to the boged digger. A bloody expensive exercise though. Usually machines have a design feature built in so they breakdown in the worst place on a job and that's why I advocate for the removal of the sprockets retaining bolts, no environmental damage, no mechanical damage because **** can't get in. Also with an excavator with track drive problems the upper works can still be used to assist.
I get the impression that this particular excavator has suffered an engine failure although the OP never actually came out and said that.
One fellow I worked with years ago was from another dealer in the chain. He was saying at the shop he came from they had a powerpack type setup and they'd connect it to the drive motors when doing midlife overhauls. Split the hoe in half, walk the undercarriage out the door and then walk it back in again once it was time to put it all back together.
We had a hydraulic powerpack for towing the big Cat off-highway trucks. It could be hooked up to the dump body cylinders to dump the load if the truck happened to be that way. It provided hydraulic pressure to get the parking brake released, and also provided power for the on-board electric supplemental steering pump so the towed truck could both steer and stop. Fantastic, stupendous, it did exactly what it said on the can - the only drawback was that it cost around $100k...!!
oh ****!!
You can pull the sun gear in the finals for about thirty minutes of labor. You can pull the travel motors and cap the hoses for about $100 in caps and plugs and labor. You can unbolt the sprockets and probably leave them in place and hope they don't get tangled up in the tracks against the final and track frames for a couple of hours of labor. Add renting another machine to tow the broken unit onto a trailer to move it somewhere it can be repaired. You can try to haywire some hoses into the main control valve and find some kind of other power unit to move the machine and pay at least of couple of days of finagling labor, the cost of the hoses and all the diapers you will need to catch the lost hydraulic oil that spills all over when you start breaking fittings loose. Add to that the cost of another machine with a hydraulic system and the same time to haywire the hoses into its system and then move the machine onto a trailer. It's all dollars and cents to which ever way to want to use your money.
If the tracks are properly adjusted the sprockets slip on the hub without any tangles, you can even do turns like on a windy road. As I've post before I had to do this on multiple occasions.
If you run hydraulics to the main system to allow folding, braking, swing, etc, you still need electrics and switching to open the appropriate solenoids. Have a dead Kobelco digger with similar problems I'll get to some day. I plan on using a port-a-power to release the swing motor brake, and either the sun gear out or unbolt the drive sprockets to run it onto the trailer. Folding it up is just going to be messy and will all be done with a skytrak and chains/load binders.
8 year old necrothread. I 'spect the original hoe is razor blades by now.
I've picked up a dead excavator from ACE before. We lifted it with a crane, but it got to their yard on a transporter, with the help of a guy who has built a remote power-pack for recovering dead equipment
Can interior electronics still function with engine removed?
Unlikely.
