Call for help...

[The Extractor]

Hi guys , new here and pretty new to the big stuff. Cool stuff going on here!
I used to work at a machine and welding ship in CA that my Grandfather started in 1947 as a machinist and repair guy. Anyway now I am in CO and my landlord has a forwarder that needs repair and if I can get it fixed by the 3rd of Jan I get a free months rent= $500 . I have done some hyd work but not really system trouble shooting. I have basically a pressure guage to work with. He will buy whatever I need pretty much. It has a grapple boom on the rear and blade in the front. The boom does not work at all and the blade is very slow. The boom has hyd/hyd and elec/hyd controls. the blade is elec/hyd. I would really appreciate ANY help you guys can provide. I can post pics of the machine. I hope I can get some help here or be pointed in the right direction. Thanks in advance. - Andy:notworthy

What kind of machine is it? Start by making sure it is full of oil. Go to the main implement pump check output pressure, then to the filter housing check the pressure through it, You might have to get a flow meter or borrow one from a local dealership if they will let you.Check the gallon per minute through the pump and valve body.

[The Extractor]

The bad thing about this machine is that it is a one off prototype Kamaco.
There is good clean oil in the tank. I will see about getting a flow meter to test the flow. It seems to have pressure everywhere I can test except I found one line that has no pressure and probably should.http://i17.photobucket.com/albums/b83/OLDARMY45/DSCN1482.jpg

more later , have to get back to work.

there's SNOW in that picture...i HATE snow!!!

[The Extractor]

I dont really have any love for snow either.... I need to get this thing fixed...
It is snowing right now.... I think Im sol on this....:crying

[Countryboy]

It is articulated right? Will it turn or is that a problem too?

[The Extractor]

Yes, it is articulated. It steers no problem. The trans also functions correctly.
It just seems that all the "accessories are having problems. Thanks for the reply.:)

Good luck with the job extractor but for troubleshooting you really need a hydraulic and electrical schematic to understand how the machine is supposed to work, whether it has gear, piston pump or other how the spools are shifted etc.

Tellling us the manufacturer of the hydraulic system and describing the implement pump might help though...

[Dwan Hall]

All in all the price for the repair should run well over the $500 credit you will be getting unless you spend less then 10 hours on it.

[Countryboy]

Did he buy it from a dealer? I searched the net for Kamaco and came up with absolutely nothing. Not even a picture or even anything about equipment. In your second post you said its a prototype. Do you mean its the only one? I just don't see where you will be able to find the parts because it doesn't sound like a quick fix or atleast not for $500. I could be wrong but thats my gut feeling.

Good luck. :yup

Most of the hyd parts are parker and vickers. The tags are misssing from all 3 darn pumps. I have the electrical schematic which is good, but there is no hyd one available as it is a one of a kind machine. Kamaco(sp?) makes sugar cane harvesting equipment. I think he bought is off of ebay. The spools are mostly
elec over hyd with rocker switches. I am not paying for any parts just my time is all I am investing. This last weekend I found a line that had no pressure at all no matter what I turned on or off. I am pretty sure it is related but not sure how to proceed. I really do appreciate all the help. Keep it comin. Thanks - A

This is a link to my album with photos of the hyd system under the cab.

Your pictures show that the machine is pretty complex and I don't recognise the pump manufacturer or type. Is it possible that the machine is a Cameco because they have been acquired by Deere. If this is the same manfacturer they may still have schematics and technical staff that could help?

[The Extractor]

It is a Cameco. It is also a prototype with no HYD schematic available. The owner asked for it and they said one didnt exist because it is a one of a kinda machine.:Banghead

Can you access the hydraulic filters or return screens on the machine? Contamination in either the return filter or return screen would indicate component failure. The type of material found could determine which component failed ie, pump, cyl. Furthermore, contamination could further cause the relief valve of control spool to hang open thus diverting delivery oil back to tank. Based on the picture you sent, it looks as though the front attachment requires much less volume than the boom assembly thus indicating a volume or flow issue which further points to the pump. I would definitely inspect the filters and screens to start.

[The Extractor]

Thanks for the help. It is all kind of moot now however . I fell asleep at the wheel on my way to CO from CA for the Holidays and have a compression fracture in my back.

Thanks for the help. It is all kind of moot now however . I fell asleep at the wheel on my way to CO from CA for the Holidays and have a compression fracture in my back.:confused: Ouch!!

Good luck, and I hope you have a speedy recovery.:yup

[Countryboy]

I hate to hear that especially during the holidays. Back injuries aren't nothing to play with. Best of luck with your recovery. :)

[Jeff D.]

The Extractor, if you don't mind me asking, how bad of shape did you end up in? What vertebra did it fracture? What did the doctors do with it?

I ask because in '88 I fractured my c-5 vertebra, and bruised the spinal cord enough that I was paralized for about 2 weeks, from an accident. It was very scary for me. Couldn't move anything. The Doctors cut out a piece of my hip and fused the c-5 and c-6 vertebra together, along with adding some metal. It was a long, but almost complete recovery for me that took about a year.

I can empithise(sp?) with what it must be like right now for you.

Stuff like that sure can make a guy realize what's really important in life, fast.

[LowBoy]

I have the remedy to the whole dilemma, Extractor. Chain the front blade up, take the flame wrench and mow the loader off the back. Have the owner buy 2 truck-mounted loaders and just load the forwarder with one, and haul the logs down to the header with it. At the header, loader #2 will unload it.
You can enjoy a full recovery without getting your hands dirty that way, and production is at a premium. Plus you don't have to rack your brain figuring the problem out.

Just a thought.:laugh

[The Extractor]

it is my T-12 I think.... The one the bottom rib attaches to. I am so very blessed that I am not in worse shape than I am. Basically they sent me home with brace. There is a small piece of the bone somewhat loose in there,
but it is a long way from "the cord". It doesnt even really hurt that bad I am up and around with not much trouble which is awesome. Lots of small tasks are now a challenge but I can deal with it. Ill see about getting some pics up.

[Jeff D.]

It's not good to hear that you got busted up, but it is good to hear it wasn't worse.:yup

That thing was tore up bad. Wow!

[jmac]

Wow you are lucky, I think you had an angel on your shoulder! Driving that truck helped. Hope every thing turns out ok.
