The Extec C12 Jaw crusher destroyed?

Is this the end of the Extec Crusher?
I sold it to a contractor knowing it was worn out, even though I told them there were issues with the crusher I feel sorry for them. In this video Extec C12 year 2008, Volvo EC380EL, Metso 106, Keestrack K4 scalper. Cat 982M Loader, and my Toyota Hica ;)

The final set up was fascinating to watch and very efficient. 1 in to 3 out and sorted. Wonderful! Thank you.

Why did you keep running it if you suspected a problem !!

[@ConstructionMachineryChannel]

Once again thanks for the nice close ups, much appreciated .

[@allistairc123]

Great to see some crushing content! What is the bucket on the Volvo designed for looks like a boulder handler!? It looks awful with that super long edge and teeth, weak curl force

[@jameslindley924]

Super long to retain deep slabby stone and get under virgin slab

this is the first time i have watched a video of a crusher that sounds like that it just did not sound right to me but it's first time i have seen a video of this crusher to so i don't know what it should sound like

[@merlinjust4753]

Wondered why they kept running it

[@thenussbaum44]

Looks like this other contractor brought some man size equipment to the job.

My question is how did hydraulic oil get into the engine? Yes you said a seal broke but that means that another seal possibly broke or something else major.

[@ashboy225]

Hydraulics run within multiple thousands of psi, where as an engine might only been 50/200psi range. So the hydraulic pressure just blows past the engines main crank seals quite easily seeing as its not made to hold back thousands of psi

[@thecoffeecup144]

@@ashboy225 you have a point, I completely forgot that hydraulic oil can be compressed to the thousands in psi

[@ryanozbun8933]

a leaking pump even internally leaking is hardly the end of a machine. Ive fixed pumps like that several times, and the hydraulic fluid will not lock up an engine due to lack of lubricity.

[@evjone]

but it eventually will cause engine to hydrostatic lock due to engine oil filling the cylinder below the piston....

[@ryanozbun8933]

@@evjone sure no doubt you've gotta fix it. It had to of been leaking a while for that. Typically it starts leaking s little before it jjst completely lets got

[@jameslindley924]

Did Hydraulic Oil get through the Hydraulic Pump drive seal and through the Crankshaft seal into the Engine please???????? What Engine is in that C12 ??- They usually fitted CAT 3306 Engines but i think there were some Air Cooled Deutz also

[@evjone]

Yes it did, Deutz V6 engine. Dont know exactly engine name

[@Radionut]

Have you ever found anything unusual or strange Wiles crushing and sorting your rock? I mean like bones or something unexpected? Great video I love the sound of the crusher

[@evjone]

Lots of tools and spare parts ;) fossils, ancient wood rare minerals, no gold or diaminds...yet...

[@sufianofficial7390]

Nice for making road

[@xxbal1inxx]

We had one of these at my old job, very fast but was super unreliable

[@evjone]

Its sort of reliable, in a way. There is no electronics, and mostly mechanical parts

[@jameslindley924]

What Country are you Guys in ?

[@evjone]

Norway

[@Megashovelman]

Looks like 3 different stone sizes being made.

[@evjone]

0-20mm , 20-60mm. 60-120 mm

[@Sasskin]

Is the extec your crusher or are you renting it?

[@evjone]

it WAS mine, sold it now

[@TomJones-zm3kz]

Yes something is wrong with the engine. These systems are usually designed to have higher oil pressure so that if a seal goes it pumps engine oil into the hydraulic. You'll know bc you will lose engine oil and the hydraulic will start looking very dirty. I suspect your engine had low compression.

[@jameslindley924]

Top Crusher was C12+ !!!!!!! Belting Machine !!!!

[@helicopter269]

The extec is a mutch faster crusher
